Various Types of Steel

Although steel consists mostly of iron and carbon, the World Steel Association reports that more than 3,500 grades of steel are in existence, each featuring unique chemical, physical and environmental properties. The amount of carbon, additional alloying elements, and level of impurities contained determine the properties of each grade. Even though the most commonly used grades of steel contain between 0.1 and 0.25 percent carbon, some can have a carbon content of up to 1.5 percent. All grades of steel contain elements like manganese, phosphorus, and sulfur. While the last two are known to have deleterious effects on the strength and durability of steel, manganese has significant benefits.

 

Steel is produced in various forms, each featuring unique properties that may have been manipulated to fit specific applications. These properties are the basis of every grading system used to distinguish one form of steel from the other. According to AISI, steels can be grouped into the following categories depending on their chemical compositions or metal alloy contents:

 

• Carbon steels

• Alloy steels

• Tool steels

• Stainless steels

 

Carbon Steels

Carbon steels contain iron, carbon, and trace amounts of other alloying elements. Carbon is, however, the main alloying constituent of carbon steels, which account for approximately 90 percent of all steel productions. Because it has small enough atoms, carbon can travel through iron’s crystal lattice, filling the gaps between the metallic atoms and distorting the metal’s lattice slightly. As a result of this, the metal becomes much stronger and a lot more rigid. Carbon is the hardest element, which is why carbon steel products are also very hard. Varying the percentage of carbon produces steel with different qualities. However, higher carbon content often translates to stronger yet more brittle steel. Depending on the level of carbon contained, carbon steels can be classified into the following groups:

• Mild or low carbon steels that contain up to 0.32 percent carbon

• Medium carbon steels, containing 0.30-0.59 percent carbon

• High carbon steels, known to contain over 0.6-0.99 percent carbon

• Ultra-high carbon steels that usually contain about 1.0–2.0 percent carbon

 

Also known as wrought iron, low carbon steel is the commonest and most cost effective form. It is easy to work, making it suitable for decorative products like lamp posts and fencing. As one of the stronger variants, medium carbon steel is often used to forge large structural applications and automotive components while high-carbon steel is mostly used for high-strength wires and springs. Also known as cast iron, ultra-high carbon steel is the hardest form of them all and often used for knives, axles, punches and other special purposes. Since carbon steels do not contain chromium, they tend to corrode faster than almost every other type of steel.

 

Pros

Depending on the variant, carbon steels are:

• Strong

• Durable

• Extremely hard

• Ductile

• Affordable

• Resistant to wear

• Malleable

• Offer exceptional machinability when treated with sulfur

• Can be tempered to great hardness

 

Cons

• Poor rust resistance

• Relatively low tensile strength

• Some types suffer from yield-point runout and can, therefore, require high levels of maintenance.

 

Alloy Steels

The name comes from the fact that steels in this group contain a small percentage of other metals besides iron. Alloy steels contain common alloy metals in varying proportions, which makes this type of steel suitable for specific applications. These alloy metals include aluminum, manganese, nickel, titanium, silicon, copper, and chromium, the addition of which produces properties that are different from those found in regular carbon steels. When added, alloying elements can change properties like strength, ductility, formability, hardenability, and ability to resist corrosion. For instance, stainless steel is produced by adding chromium and nickel whereas the addition of aluminum results in a more uniform appearance. On the other hand, the addition of manganese is known to make steel extremely hard and strong. Alloy steels can have diverse mechanical properties due to the broad range of compositions possible.

 

Pros

Depending on the variant, alloy steels are:

• Economical

• Widely available

• Easy to process

• Resistant to corrosion

• Hard

• Strong

• Responsive to heat treatments

 

Cons

• The hardness has a negative impact on workability

• Can be allergic, especially if it contains nickel

 

Because of the properties mentioned above, alloys steels serve a broad range of applications including the manufacture of pipelines, transformers, auto parts, electric motors and power generators.

 

Tool Steels

This type of steel is alloyed at very high temperatures and often contains hard metals like tungsten, cobalt, molybdenum and vanadium. Since they are not only heat resistant but also durable, tool steels are often used for cutting and drilling equipment. Even so, there are various types of tools steels, each containing varying quantities of different alloy metals. As a result, each type of tool steel offers a different level of heat resistance and durability.

 

Pros

• Extremely durable

• Highly heat resistant

• Strong

• Hard

 

Cons

• Limited application

• Difficult to manipulate

 

Stainless Steels

Although stainless steels comprise of several metal alloys, they usually contain 10-20 percent chromium, making it the primary alloying element. Compared to the other forms of steel, stainless steels are approximately 200 times more resistant to rusting, especially the types that contain at least 11 percent chromium. As a result, stainless steel is highly valued for its ability to resist corrosion. Based on their crystalline structure, stainless steels fall into one of the following categories:

 

1. Austenitic steels

Although austenitic steels contain trace amounts of nickel (eight percent) and carbon (0.8 percent), they are high in chromium. In general, austenitic steels have a chromium content of about 18 percent. With applications like the manufacture of pipes, kitchen utensils, and food processing equipment, austenitic steels are the most commonly used type of stainless steel. Even though austenitic steels are not responsive to heat treatments, they are valued for their non-magnetic properties.

 

2. Ferritic steels

Apart from containing trace amounts of nickel, less than 0.1 percent carbon, and about 12-17 percent chromium, ferritic steels usually contain alloy metals like molybdenum, aluminum or titanium in small quantities. Ferritic steels are magnetic, tough, and very strong. However, cold working can be used to strengthen them further. Unfortunately, they are not responsive to heat treatment, meaning no heating technique can be used to harden them.

 

3. Martensitic steels

In addition to containing moderate amounts of carbon (about 1.2 percent) and nickel (less than 0.4 percent), martensitic steels contain 11-17 percent chromium. Aside from having magnetic properties, martensitic steels are also responsive to heat treatments. This type is mainly used to make dental and surgical equipment, blades, knives, and several other cutting tools.

 

Stainless steels have the ability to withstand most of the wear and tear caused by everyday use, making them highly durable. Additionally, an invisible layer of chromium serves to prevent oxidation, making stainless steels resistant to scratches and corrosion.

 

Pros

Stainless steels are generally:

• Low maintenance

• Highly resistant to scratches and corrosion

• Durable

• Hard

• Affordable

 

Cons

• Easy to dent

• The inclusion of nickel raises allergic concerns

• The hardness means limited workability

 

As evidenced by the properties offered by each of the forms, steel has qualities that can meet a broad range of applications. In fact, steel serves an array of construction, appliance, energy transport, and packaging purposes in today's world.

Portable Geo Specific Water Filtration Bottle

Students of Indian Institute of Technology Madras Ramesh Kumar and his team member Anupam Chandra won the award appreciation for developing a prototype of Portable Geo Specific Water Filtration Bottle. He carried his project work under guidance of Prof. T. Pradeep.

In all natural calamities, those who get most affected are the poor and affordable solutions are essential for alleviating their sufferings. In regions, such as West-Bengal and Assam where flood water can also contain regional contaminants such as arsenic, rapid removal of particulates, microbial, chemical and regional contaminate such as arsenic and fluoride require a combination of technologies to be effective at acceptable flow rates. A personal water purifier to deliver one liter of clean water from arsenic contaminated water requires materials with enhanced removal kinetics and high adsorption capacity so that filter is effective. This is currently possible only with advanced nano-materials in conjunction with other technologies such as nanofiltration, reverse osmosis, etc. Here it demonstrates an affordable purifier involving multiple technologies for microbially, chemically and heavy metal safe drinking water. In this purifier bottle, feed water passes through four stages of filtration, 1) reusable pre-filter, which removes all particulate matter, 2) microfiltration / ultrafiltration hollow fiber membrane cartridge, which removes all microbial and viral contaminants, 3)geo-specific filtration unit, which removes geo-specific contaminant such as arsenic, fluoride and pesticides, 4)silver nanoparticles decorated activated coconut charcoal, which provides antimicrobial and organic contaminant removal capacity to the water purifier bottle. To develop pressure required in feed water container vessel for microfiltration or ultrafiltration, a hand operable bellow pump is added to the unit. Cheap and indigenously developed filtration membranes make this water purifying device affordable for mass distribution to the affected population of a natural disaster.

Design of Highly Efficient and Inexpensive Membrane Equipment as Import Substitutes for Demineralized Water Production and Hemodialysis

Students of CSIR- Indian Institute of Chemical Technology, Hyderabad Harsha Nagar including her team members M. Madhumala, Shaik Nazia, Y.V.L. Ravi Kumar won the award appreciation for developing a Design of Highly Efficient and Inexpensive Membrane Equipment as Import Substitutes for Demineralized Water Production and Hemodialysis. She carried her project under guidence of Dr. S. Sridhar.

Demineralized (DM) water has gained huge applications in various industries including hospitals, laboratory for culture preparation, cooling systems, laser cutting etc. Therefore Membrane Separations Group of IICT has designed a highly compact and low cost two stage cascaded membrane system which would produce 40-60 L/h capacity of demineralized water with a total dissolved solids (TDS) of zero ppm. The system costs Rs. 35000/- only as compared to Rs. 5 – 10 Lakhs charged by multinational companies. The unit produces demineralized water at a cost of 5 Paise per liter with a low maintenance. The another innovation reports the design of low cost spinneret for making synthetic polymeric hollow fibers having different sizes which are used for Dialysis and water purification. The spinneret consist of a bore fluid pin, the lower part of the extruder/polymer solution reservoir which is connected to venturi shape taper with varied diverging part where various concentric polymer clearance can be achieved according to the application. The detachable bore fluid pin mounting design allows hollow fibre with inner diameter ranging from 110 microns to 800 microns. Different sizes of diverging part of venturi shape of taper connected to polymer reservoir allows for the manufacture of hollow fibers having different sizes.

A Mechanism for Toilet Seat Sanitation

Students of Indian Institute of Technology, Madras Arvind Pujari and his team members Shashwat Jain, D V S S S Kushal Kumar Reddy, Subham Kumar Sahana and Tanay Garg won the GYTI award appreciation for developing a A Mechanism for Toilet Seat Sanitation.

A simple, purely mechanical device is developed to ensure the sanitation and cleaning of the toilet seat by the push of a foot pedal which can be implemented as an add-on to the existing toilet structure. The mechanism consists of three parts. a) A Lifting Mechanism: A foot pedal lifts the seat, as seen in dustbin lids. b) A Spraying Mechanism: When the seat reaches its apex position, a nozzle is automatically pressed, spraying a sanitizing liquid onto the seat. There are four such nozzles, thus ensuring that the entire seat is sterilized. c) A Wiping Mechanism: The wiper is a rod attached with a removable sponge, located at the back end of the seat, so that it does not encumber the user. When the foot pedal is pressed, the seat is lifted and the wiper is lifted along with the seat until it reaches the front edge, thus cleaning the seat of any dirt or water left by the previous user. Then the spray heads attached to the lid of the seats are pressed and spray a sanitizing liquid on the seat. The spray is uniformly spread and wiped across the seat, by the wiper, thus completely sterilizing it. There are many advantages of this mechanism over currently implemented methods (such as disposable seat covers, sanitary wipes, sanitary sprays and UV light). Thus, this device provides a low cost (the device will cost less that 1000 to manufacture and set up), user friendly, touch free and electricity free method of sanitizing and cleaning the toilet seat by the simple push of a foot pedal.

Grid Interactive Solar PV Based Water Pumping Using BLDC Motor Drive

Rajan Kumar, student of Indian Institute of Technology, Delhi received the Gandhian Young Technological Innovation Award-2017 appreciation for developing a prototype of a Grid Interactive Solar PV Based Water Pumping Using BLDC Motor Drive under the guidance of Prof. Bhim Singh.

Being a grid-isolated or standalone system, the existing brushless DC (BLDC) motor driven water pumps fed by a solar photovoltaic (SPV) array, rely only on solar PV energy. Due to its intermittency, the solar PV generation exhibits its major drawback which results in an unreliable water pumping systems. In the course of bad climatic condition, water pumping is severely interrupted, and the system is underutilized as the pump is not operated at its full capacity. Moreover, an unavailability of sunlight (at night) leads to shutdown of an entire water pumping system. This innovation proposes a bidirectional power flow control of a grid interactive SPV fed water pumping system. A BLDC motor-drive is used to run a water pump. This system and control enable a consumer to operate the water pump at its full capacity for 24-hours regardless of the climatic condition and to feed a single-phase utility grid when the water pumping is not required. The full utilization of SPV array and motor-pump is made possible in addition to an enhanced reliability of the pumping system. Using a single-phase voltage source converter (VSC), a unit vector template (UVT) generation technique accomplishes a bidirectional power flow control between the grid and the DC bus of voltage source inverter (VSI) which feeds a BLDC motor. The maximum power point (MPP) operation of SPV array, and power quality standards such as power factor and total harmonic distortion (THD) of grid are met by this system

Paper-based device for rapid detection of Dengue

Sanjay Kumar and his team member Pulak Bhushan won the award appreciation for developing a Paper-based device for rapid detection of Dengue. He carried his project work under the guidance of Prof. Shantanu Bhattacharya, Indian Institute of Technology, Kanpur.

Dengue virus is diagnosed using conventional techniques like PCR (polymerase chain reaction) and ELISA (enzyme-linked immunosorbent assay), and even though these methods are highly accurate they need a highly clean lab and expert people to perform these tests. They are also highly expensive and time consuming. The previously developed devices have one major limitation from the commercial point of view. They utilize saliva or serum as their samples. Even though they are an important source of biomarkers and have less interference, they require pre-processing before they can be used. The pre-processing can only be done in a laboratory rendering it useless for developing commercially available lateral flow test strips. Several rapid diagnostic devices are available in the market for detection of dengue. The devices that detect NS1 are only capable of doing so after 3-4 days, since that is when the concentration of Ns1 increases to a considerable amount. Whereas, the devices that can detect IgM and IgG, suffer from the problem that these antibodies are produced in the body only after 4 days and 7 days respectively (primary infection), hence rendering them useless for early detection purposes. The primary objectives of this project are as follows: Development of a device which can detect dengue NS1 in the first 1-2 days itself, when the concentration of NS1 is considerably low. This shall make the device capable of providing an early diagnosis which will further aid the doctors in treating the patients in an effective way. Using whole blood as the sample, eliminating the need of pre-processing which requires external equipment and expertise.

OCR++: A Robust Framework For Information Extraction From Scholarly Articles

Students of the Indian Institute of Technology, Kharagpur were received the Gandhian Young Technological Innovation Award-2017 for developing a website of OCR++: A Robust Framework For Information Extraction From Scholarly Articles.

Mayank Singh Including his team members Barnopriyo Barua, Priyank Palod, Manvi Garg, Sidhartha Satapathy, Samuel Bushi, Kumar Ayush, Krishna Sai Rohith, Tulasi Gamidi developed this website under guidence of Dr. Pawan Goyal and Dr. Animesh Mukherjee.

This project proposes OCR++, an open-source framework designed for a variety of information extraction tasks from scholarly articles including metadata (title, author names, affiliation and email), structure (section headings and body text, table and figure headings, URLs and footnotes) and bibliography (citation instances and references). A diverse set of scientific articles written in English to understand generic writing patterns and formulate rules to develop this hybrid framework is analysed. Extensive evaluations show that the proposed framework outperforms the existing state-of-the-art tools by a large margin in structural information extraction along with improved performance in metadata and bibliography extraction tasks, both in terms of accuracy (50% improvement) and processing time (52% improvement). A user experience study conducted with the help of 30 researchers reveals that the researchers found it to be very helpful.

For this project Prof. Anil K Gupta Co-ordinator, SRISTI and Founder, Honey Bee Network, honored Mayank Singh and his team members Barnopriyo Barua, Priyank Palod, Manvi Garg, Sidhartha Satapathy, Samuel Bushi, Kumar Ayush, Krishna Sai Rohith, Tulasi Gamidi, Indian Institute of Technology, Kharagpur, with the prestigious Gandhian Young Technological Innovation (GYTI) Award 2017 at Rashtrapati Bhavan.

Fish-Inspired Propulsion System for Remotely Operated Surface Ships and Underwater Vehicles

Mannam Naga Praveen Babu won the award for the research project ‘Fish-Inspired Propulsion System for Remotely Operated Surface Ships and Underwater Vehicles’. He carried his research work under the guidance of Prof. Krishnankutty P. Department of Naval Engineering, Indian Institute of Technology Madras, Chennai.

The Autonomous Marine Vehicles (AMVs) are much in use for exploring subsea natural resources, monitoring marine pollution, performing hydrographic surveys, etc. Energy for AMV operations are taken from battery cells provided inside the AMV. The energy consumption can be reduced by providing the AMVs with a propulsion system which is more efficient than the conventional screw type thrusters. Recent advances in planetary sciences shows that NASA is trying to explore liquid atmospheres such as methane lakes, icy crust atmospheres in Jupiter's largest moon Europa and Titan planets with the help of robotic eel fish and underwater submarines. The use of marine vehicles on earth ocean's world exploration advances into planetary atmospheres. Compared to conventional marine vehicles, bio-inspired swimming vehicles have shown higher performance in comparison to screw propellers. This performance results in efficient cruising, maneuverability (turning and stopping ability), noiseless motion and eco-friendly. These are defined as fish-like bio-inspired vehicles which propel through undulation or oscillation motion of the fish body or its fins. Flapping foil propulsion are more efficient (80%) than the conventional screw propulsion system (60%). Use of flapping foils also disturbs the water less compared to screw propellers, thus making it more environment friendly and create less noise. With these perspectives under consideration, the present research reports the studies carried out on a remotely operated surface ship model and underwater vehicle fitted with a fin at the aft end, resembling caudal fin of a thunniform fish. The aft (tail) fin has freedom to oscillate in the horizontal plane about the longitudinal axis. Self-propulsion tests are carried out for determining the thrust performance of marine vehicles

Never Ending Learning Of Sound

Ankit Shah including his team members Rohan Badlani, Benjamin Elizalde, Anurag Kumar National Institute of Technology, Surathkal received the Gandhian Young Technological Innovation Award-2017 for developing an application on Never Ending Learning Of Sound. He carried his project under guidance of Prof. Bhiksha Raj.

Sound recognition is critical to the development of artificial intelligence. However, sound recognition remains an arcane task for computers, given the incomplete understanding of how humans are able to recognize sound and understand its meaning naturally. Never Ending Learning of Sound (NELS) is a system that will continuously learn about sounds through direct supervision or automatically, and expand its vocabulary of sounds through analysis of audio and multimedia recordings and thei r corresponding metadata. It will eventually present a comprehensive repository of sounds – an invaluable resource in many fields – ranging from automatic video content analysis to audio forensics. India is on its path to a digital transformation, and a semantic understanding of sounds from NELS will help create smarter cities, robotics, automated surveillance systems and will also redefine tangible experiences for approximately 60 million deaf people in India. NELS will identify known sounds and detect the occurrence of new. Then, learn to recognize new sounds and associate their semantics and metadata to increase its vocabulary. It will also learn hierarchies in the structure of sounds, learn physical and common-sense structural and temporal relationships between sounds, and associations between sounds, their meaning and semantics and categories. NELS system will provide the largest and most up-to-date available repository of sounds in the world.

Dr. Francis Gurry, Director General of the World Intellectual Property Organization (WIPO), honored Ankit Shah and his team from Department of Computer science, Information technology & related fields, National Institute of Technology Surathkal, with the prestigious Gandhian Young Technological Innovation (GYTI) Award 2017  at a function held at Rashtrapati Bhavan on March 5.

Blood Quality Assessment using Digital Holographic Microscopy

Mandeep Singh including his team member Azhar Muneer won the award for the research project Blood Quality Assessment using Digital Holographic Microscopy. He carried his research work under the guidance of Dr. Kedar Khare and Dr. Sarita Ahlawat Indian Institute of Technology, Delhi.

The stored blood in blood banks is used regularly in surgical procedures or transfusions. Blood quality assessment is therefore an important routine task. Current blood quality assessment protocols involve a number of chemical assays or impedance measurements making the process cumbersome and difficult to standardize. In recent years IIT Delhi has developed and patented a superior DHM technology for accurate high resolution 3D imaging of biological cells for blood cell classification and quality assessment. DHM operates on the principle of interference of light and can provide accurate information regarding minute refractive index changes in the cells that are ultimately related to cellular changes in response to ageing, physical cell damage or infections. Using the novel 3D imaging capability of this prototype system has indicated that fresh and old red blood cells have clearly distinguishable morphological features.

Mandeep SinghThe specialty of the DHM technology is that the usual wet-lab processing of cells prior to their analysis can be minimized thus significantly reducing recurring costs for chemical reagents. With a more systematic effort in this direction the aim is to develop a methodology for blood cell classification and quality testing that can benefit large number of hospitals, blood banks and pathology labs across India and beyond. The work is expected to lead to an early application of an indigenously developed microscopy technology with superior imaging performance.

Enhancement of Distribution System Performance using High Voltage Alternating Current (HVAC) Boost Converter and Fuzzy Controller

Anusha Vadde Student of the M. S. Ramaiah University of Applied Sciences, Bengaluru received the Gandhian Young Technological Innovation Award-2017 for developing a prototype Enhancement of Distribution System Performance using High Voltage Alternating Current (HVAC) Boost Converter and Fuzzy Controller. She carried her project under guidance of  V. S. N. Sitaramgupta V.

Power quality is one of the key factor in electrical systems and is taken into consideration to meet the demands of the customer. Voltage dips, momentary interruptions, harmonics and transient surges affect the reliability and quality of the power supply. The reliability and cost of any electrical system depends on the quality of the supplied power and consumed by the system. High Voltage Distribution System (HVDS) is one of the methods used to improve the quality and reliability of the distribution system through a reduction in losses, voltage fluctuations and power consumption. In HVDS, power is transmitted from the distribution station to consumer premises through the booster transformers and voltage regulators. Inrush currents or magnetizing currents and heating of insulation have been observed in transformers due to non-linear loads. As a result, the current drawn by the system is high. To overcome these effects, a step-up power converter with fuzzy controller has been designed. In this research work, High Voltage Alternating Current (HVAC) Boost Converter with fuzzy controller has been proposed for a costeffective solution to reduce distribution losses. Simulation studies have been carried out for verifying the utilities of the proposed design. The performance of the designed fuzzy logic controller is compared with that of the existing booster transformer scheme by using the simulations. It has been found that the efficiency is improved by 4%, and power losses are reduced by 1.4% to maintain the voltage fluctuations within the acceptable levels. The proposed controller in the case study of old city area in Hyderabad has been shown that revenue savings are increased by 12%.

Dr. R A Mashelkar, Chairperson, Research Advisory Committee, SRISTI and NIF, honored Anusha Vadde, Department of Electrical, Instrumentation & Related Fields, M. S. Ramaiah University of Applied Sciences, Bengaluru with the prestigious Gandhian Young Technological Innovation (GYTI) Award 2017  at a function held at Rashtrapati Bhavan on March 5.

Affordable Paper Microfluidic Device for Blood Glucose and Cholesterol Detection

Avisek Barla and his team members Abrar Ali Khan, Sameer Sharma, Vijay Anand, Nitish Kumar Singh  won the award for the research project Affordable Paper Microfluidic Device for Blood Glucose and Cholesterol Detection. He carried his research work under the guidance of Dr. Vignesh Muthuvijayan, Indian Institute of Technology, Madras.

Non-communicable diseases (NCDs) can easily be held responsible for majority of the deaths worldwide and India is no exception. The work is done on detecting diabetes, cholesterol and predict its cumulative effect. There are specific cases of brain stroke leading to complete or partial paralysis including severe cognitive impairment in the long term. The huge demand for diagnosis has flooded market with Point of Care devices for diabetes, but not yet for cholesterol. The cost of an average device is Rs 800-1500 in the market, but in this project, the price point of the strips used is around Rs 15-50. Thus, a lowcost paper based sensor meant for the masses is made. One would require to add a few drops of blood to the device and colour change will happen in the specified region. A camera is used to quantify and measure colour to display the concentration. The data collected will be used to map the prevalence of the disease and predict the occurrence of strokes. The work is in the process of making a blood drawing mechanism and plasma separation unit which will complete the picture of a true consumer device at nominal price.

Indigenous Technology of Soft Body Armour for Defence Applications Using 3D Woven Aramid Fabrics

Animesh Laha, Student of the Indian Institute of Technology, Delhi received the Gandhian Young Technological Innovation Award-2017 for developing a prototype of Indigenous Technology of Soft Body Armour for Defence Applications Using 3D Woven Aramid Fabrics. He carried his project under guidance of Dr. Abhijit Majumdar. 

Soft body armours are developed by using multiple layers of high performance fabrics. Generally, 30-40 layers of 2D fabrics woven aramid fabrics (Kevlar, Technora etc.) or ultrahigh molecular weight polyethylene (UHMWPE) sheets are assembled together to make soft armour panel which becomes heavy and inflexible. In this innovation, two approaches have been amalgamated to reduce the weight of body armour. 3D fabrics, in which yarns are arranged in three perpendicular directions, namely X, Y and Z were produced in the laboratory. 3D fabrics were then treated with shear thickening fluid (STF).

STF treated 3D fabric prototypes developed in this research have been tested against 9 × 19 mm bullets (430 m/s). Soft armour panel having STF treated 3D fabrics stopped bullets fired at 430 m/s. The areal density of the panels was 4500 g/m square. Moreover, the depth of back face signature for these fabrics was varying from 31 to 39 mm which is within the acceptable limit (44 mm). The panel containing STF treated 3D fabric showed dome formation, crack generation and fibre breakage to a lesser extent as compared to those of fabric panels containing untreated 3D fabrics.

Swayam- Passively Stabilized Communication Satellite

The COEP Satellite Initiative team from College of Engineering, Pune received the award for the project 'Swayam- Passively Stabilized Communication Satellite'. They carried their project work under the guidance of Dr. M. Y. Khaladkar and Dr. B. B. Ahuja.

Swayam is a pico-satellite developed by undergraduate students of College of Engineering, Pune. Swayam is a passively stabilized communication satellite of dimensions 10 X 10 X 11.35 cm and mass 990 g. Swayam was launched by ISRO on 22nd June, 2016 by PSLVC34. Swayam is currently in-orbit and data is being downlinked at COEP ground station and analysed on a regular basis. Student satellites offer a distinct challenge in terms of reliability and interdisciplinary nature of design. To achieve the highest standards of design and fabrication, the project was organized into five constituent subsystems. Attitude control is achieved by a passive magnetic attitude control system to satisfy the space and energy constraints. This system consists of an orthogonal arrangement of magnet and hysteresis rods. Volume, strength and placement of magnetic materials are the major design considerations. A numerical simulation has been developed to conclude the effect of various design parameters on stabilization time and its feasibility for the communication payload. Swayam has a half-duplex communication subsystem. Beam of the antenna is optimized to offer maximum communication link time in conjunction with the available pointing accuracy. To satisfy the power budget of the satellite, the autonomously sent beacon is sent at lesser power than the digital payload data. The power subsystem of the satellite is fully analog capable of functioning independently. Swayam as a template is ideal for carrying low profile payloads which do not require magnetically clean environment. Swayam is also an experiment which shows the cohesive application of passive stabilization for a communication satellite in low power environment.

A Novel Bio-engineering Approach to Generate an Eminent Surface Functionalized Template for the Selective Detection of Female Sex Pheromone of Certain Agriculturally Hazardous

Dr. Parikshit Moitra and Dr. Deepa Bhagat from Indian Institute of Science, Bengaluru were given the Gandhian Young Technological Innovation Award-2017 for developing a prototype of A Novel Bio-engineering Approach to Generate an Eminent Surface Functionalized Template for the Selective Detection of Female Sex Pheromone of Certain Agriculturally Hazardous under guidancep of Prof. Santanu Bhattacharya.

Plant pests exert serious effects on food production due to which the global crop yields are reduced by ~20-40% per year, as estimated by FAO. Hence to meet the world's food needs, loses of food due to crop pestsmust be reduced. Herein silicon dioxide or zinc oxide based MEMS devices are covalently functionalized for robust and efficient optical sensing of the female sex pheromones of the pests like Helicoverpa armigera, Scirpophaga incertulas and Bactocera oleae for the first time in literature.A Novel Bio-engineering Approach to Generate an Eminent Surface Functionalized Template for the Selective Detection of Female Sex Pheromone of Certain Agriculturally Hazardous

The relative sensitivity of the functionalized MEMS devices is improved by the variation in functionalization protocols that either increased the number of amine or β-cyclodextrin functionalities on each anchor site. The functionalized devices are also capable of selectively measur ing the concentration of this pheromone at the femtogram level which is much below the concentration of pheromone found at the time of pest infestation in an agricultural field. Again, the reversible use of the functionalized devices in any season under ambient conditions, photochemical and thermal stability of the devi c e s and absolut e ly t roubl e f r e e transportation of these pheromone nanosensors heightens their potentials for commercial use. Overall, a novel and unique approach is reported herein for the selective and reversible sensing of female sex pheromones of certain hazardous pests which may be efficiently and economically carried forward from the research laboratory to the agricultural field to determine the stage of prior pest infestation. Necessary actions can then be taken as and when necessary in a confined region of alerted pest attack.

Navyo – The Smart Glove

Madhav Aggarwal, Mohd. Suhail and Bhavesh Pachnanda, Students of the Delhi Technological University, Delhi were given the Gandhian Young Technological Innovation Award-2017 for developing a prototype of a Navyo – The Smart Glove under guidance of  Dr. Vikas Rastogi.

In the midst of the fast paced life and era of technology, a blind person is still in state of confusion that how will he/she manage to reach his/her destination. Due to his/her impairment, he/she is unable to find his direction (i.e. from where to take a left or a right turn) and eventually gets lost every now and then. So, another person becomes necessary for guiding him along the path. This makes him/her highly dependent on others for his mobility.

Navyo the smart gloveWith this, not only does he reduce his productivity but also, loses his freedom and confidence to walk alone. So, to cater the aforementioned problem a smart glove that will guide the person turn by turn to reach the destination via vibrations is created. Navyo is accompanied by a mobile App, interface of which is simple and easy to use. User simply needs to speak out the destination in App. Navyo then connects to app via Bluetooth and the person is ready to go. As per the map, when the left turn approaches, the frequency of vibration also starts increasing in left portion of hand indicating left turn and stops when turn is taken. This way by following different vibration patterns at different maneuver points (i.e. right turn, overhead bridges, underpass etc) destination can be reached out easily. In case, user has missed out any vibration instruction on glove, then it can be repeated by simply pressing a button on Navyo. The solution is based on haptic feedback technology which is safe and non-distractive from blind person's point of view. Also, this solution provides the hassle-free way for navigation by allowing user to speak the destination and walk with mobile phone inside pocket/purse etc.

Non-invasive, Point-of-care Diagnostic System for Early Detection of Oral Cancer using Digital Infrared Thermal Imaging

Manashi Chakraborty, Dr. Santanu Patsa and Dr. Nishat Anjum received the award for the research project Non-invasive, Point-of-care Diagnostic System for Early Detection of Oral Cancer using Digital Infrared Thermal Imaging. She carried her research work under the guidance of  Dr. Sudipa Mukhopadhyay, Indian Institute of Technology, Kharagpur.

This project is the pioneering attempt to develop a non-invasive, non-ionizing, radiation hazard free, point-of-care computer aided diagnostic framework for oral cancer detection using machine intelligence and Digital Infrared Thermal Imaging (DITI). Oral cancer is the most common cancer in India where approximately 14 people die/hour. Patients are unable to avail diagnosis due to scarcity of state-of-the-art infrastructure and oral-pathologist. Patients are reluctant to go for invasive biopsy. All these along with absence of screening facility pose hindrance to early diagnosis. Due to abnormal metabolic activities in carcinogenic facial regions, heat signatures of patients are different from that of normal subjects. Asymmetry of temperature distribution was compared between facial regions (opposite sides of frontal image and between left and right profile images) for patients and normal subjects.

Disparity_AnalysisThe analysis suggested that patients manifest greater asymmetry compared to normal subjects. This project requires only a one-time investment of a long infrared thermal camera, image processing and machine learning software and a laptop/workstation. Thus, there is minimal resource requirement. Also, Digital Infrared Thermal Imaging (DITI) has no recurring or maintenance cost. The image acquisition protocol is so simple that even a high school student can acquire the images. It provides on-spot oralcancer screening facility and is portable. Thus, screening camps can be organised even in remote villages with minimal infrastructure. As DITI has no recurring cost, it can be scaled up to cater the huge population of developing countries like India.

Affordable detection kit for Cervical Cancer

Appidi Tejaswini, Syed Basseruddin Alvi , Anurag Meena Students of the Indian Institute of Technology, Hyderabad were given the BIRAC-SRISTI Gandhian Young Technological Innovation Award-2017 for developing a prototype of an Affordable detection kit for Cervical Cancer under guidance Dr. Aravind Kumar Rengan.

Cervical cancer is treatable, if diagnosed early. The screening/diagnostic procedures available are time-consuming and explorative. A system which is simple, economical with immediate results is needed to increase frequency of screening. The innovation has paved way for the development of one such system.

Strip based device for detetcion(2)A technique is developed to quantify the acetic acid that is used for protein coagulation which is responsible for the aceto-white patches in VIA [Visual Inspection with Acetic acid, a conventional screening procedure for detection of Cervical cancer/Cervical intraepithelial neoplasia (CIN)]. The percentage of acetic acid is quantified; such that various percentages would result in various colors. This will help to identify the presence of cervical cancer/CIN without naked eye observation as required in VIA. This technique will be embedded into a paper/strip based device which can be initially used as an assistive technique but has the capability to emerge as self-screening tool. A qualitative screening procedure VIA is also quantified which can be easily embedded into paper/strip based device for the development of an economical, easy to handle kit which will increase the frequency and improve the ease of screening which would in turn increase the Cervical cancer survival rate.

Portable Biosensing Platform Based on Conducting Polymer Decorated Optical Fiber for Bacteria as well as Heavy Metal Sensing in Tap Water

Sutapa Chandra, Rosna Binish, Arvind Dhawangale students of the Indian Institute of Technology, Bombay were given the BIRAC-SRISTI Gandhian Young Technological Innovation Award-2017 for developing a prototype of a Portable Biosensing Platform Based on Conducting Polymer Decorated Optical Fiber for Bacteria as well as Heavy Metal Sensing in Tap Water under guidance of Prof. Soumyo Mukherji.

The presence of water borne bacteria and heavy metals in tap water could be a potential human health risk and may lead to death of young children and adult. To address this issue, a common platform is developed for detection of water contaminants (bacteria and heavy metals) in tap water. The primary sensing mechanism is based on change of optical properties of polyaniline (conducting polymer) due to the binding of water contaminants on the polyaniline coated fiberoptic sensor probe. The experimental setup consists of a broadband light source, light focusing optics and fiber-optic spectrometer. Depending on the analyte (heavy metals, bacteria etc.), polyaniline coated optical fibers were functionalized with different receptors. Thus, by changing the surface chemistry of the polyaniline coated sensor probe, it can be made specific towards detection of different analyte. As a proof of concept, it is demonstrated that as low as 20- 60 cfu/ml concentrations of E. coli and 1 picomolar concentration of lead ions are detectable using this system.

sutapa chandraThe deliverable will be a marketable prototype of an optical fiber sensor integrated with microcontroller unit. The novelty lies in the alteration of optical properties of polyaniline and its utilisation for water contaminants sensing. The detection limit aimed by this technology will surpass the conventional methods available for detecting these analytes. The sensitivity and specificity available by this technology ensures its applicability in water industry.

For this innovation Dr. R A Mashelkar, Chairperson, Research Advisory Committee, SRISTI and NIF, honored Sutapa Chandra, Department of Bioengineering, Indian Institute of Technology, Bombay, with the prestigious BIRAC-SRISTI Gandhian Young Technological Innovation (GYTI) Award 2017 at Rashtrapati Bhavan on March 5.

Affordable and Rapid Paper-based Test Kits for Antimicrobial Susceptibility Assays

Students of the Indian Institute of Technology, Kharagpur were received the BIRAC-SRISTI Gandhian Young Technological Innovation Award-2017 for developing an Affordable and Rapid Paper-based Test Kits for Antimicrobial Susceptibility Assays.

Shantimoy Kar including team members Tarun Agarwal, Shubhanath Behera, Varun Varma developed this test kit under guidence of Dr. Suman Chakraborty and Prof. Tapas K. Maiti. At the present scenario, increasing drug resistance of the pathogenic microbes is a global threat to the human mortality. To meet this challenge, there is a need to develop a rapid antimicrobial susceptibility testing platform. The cur rent methodologies for detec ting antimicrobial susceptibility suffer from severe limitations, thereby negatively effecting patient's survival rates. These techniques are time consuming, labor intensive, require sophisticated infrastructures and skilled personnel; which collectively increase overall cost of the diagnosis. In this context, herein, a simple paper based microfluidics platform for easy and rapid execution of antimicrobial susceptibility assays is developed.

Device schematicsThe device consists of a paper-based platform which includes four different layers: a base layer, a bacterial suspension layer, a drug layer and a top layer containing a chromogenic substrate which changes color in accordance to the bacterial metabolic activities. The developed technology provides faster detection (~ 5-6 h) and multiplexing (upto 8 different samples could be analyzed) in comparison to the gold-standard stereotype laboratory practices. Moreover, portable nature and ease of fabrication method collectively make it more convenient for functioning at resource limited settings.

NeuroBuds: Brain Wave Mapping Smart Earphones for Rural India

Nitin Vasanth, student of the Cochin University of Science & Technology, Cochin received the BIRAC – SRISTI Gandhian Young Technological Innovation Award-2017 for developing a prototype of a NeuroBuds: Brain Wave Mapping Smart Earphones for Rural India under the guidance of Prof. Unni A M.

NeuroBuds PrototypeAn average human brain consists of over 80 billion neurons. These communicate with each other by sending short ionic impulses, which in turn creates small voltage fluctuations around the proximity of brain. By placing highly sensitive sensors, these fluctuations can be used to understand the brain activity. NeuroBuds is a pair of smart earphones that have these specially fabricated sensors embedded into it to understand the brain activity of user. These sensors are integrated into the architecture of an earphone along with a pre-processor. The data from the sensor is passed on to the Smartphone from where the rest of processing is done. This way of utilization of smartphone processor and smartphone battery to power NeuroBuds reduces the requirement for dedicated on-board processor and battery module reducing the size of device greatly. More importantly this helps reduce the device cost to a price point that makes it accessible to common man who is usually unable to explore other expensive brain activity solutions that exist now. The brain data is analysed to look for anomalies in pattern that indicate brain disorders like Epileptic seizures. This kind of early detection helps in doing pre-emptive action and sending out alerts/SOS. The brain wave data is also used to analyse the mental state of the user, their concentration levels and stress levels. At a time when the working population suffers from stress related issues and sleeping disorders due to a fastpaced lifestyle, NeuroBuds can be used as a mental health monitor. Once the application has enough data coming in from different users, it can recognize patterns and optimize algorithms on its own using the underlying neural network. NeuroBuds serves as the perfect link between the user and the smartphone to monitor other body vitals including heartbeat.

Design & Development of Automated Five Axis CNC Ball End Magnetorheological Finishing Machine

Dilshad Ahmad Khan and his team member Faiz Iqbal, Zafar Alam won the Appreciation award for the project Design & Development of Automated Five Axis CNC Ball End Magnetorheological Finishing Machine. He carried his project work under the guidance of Dr. Sunil Jha, Indian Institute of Technology, Delhi.

The project is an innovation and technology based work aimed at providing nano level finish on various materials of complex shapes and size. This project is related to the design and development of a fully automated five axis CNC ball end magnetorheological finishing (BEMRF) setup from the conceptual idea to an industry standard machine. The developed machine caters to the demand of today's advanced industries which deals in finishing of 3-D dies, high precision lenses, orthopaedic implants, jewelleries and gems etc. In the first phase of the project an idea is conceptualized to finish 3-D complex surfaces using magnetorheological polishing (MRP) fluid. After checking the feasibility of the concept, a BEMRF tool is developed which is later mounted on a CNC machine setup. The newly developed finishing process is used to finish ferromagnetic as well as nonmagnetic materials of complex shapes and sizes using specially prepared magnetorheological polishing fluid. Apart from nano finishing on the surfaces, the measurement of surface roughness of the workpiece is also needed to be wear free which is not the case in stylus based measurement systems. Therefore, a non-contact roughness measurement instrument (confocal sensor) is incorporated in BEMRF machine. The confocal sensor is light, compact and easily mounted on the BEMRF tool for quick and error free measurement of surface roughness after the BEMRF process. In BEMRF machine the forces can be controlled automatically thereby enabling the user to select suitable force according to the material to be finished.

Low Cost Automated Handheld Melamine Detection Device (for Testing Melamine in Milk)

Students of the Indian Institute of Science, Bangalore Dhiraj Indana including his team member S.C.G. Kiruba Daniel, Varun S, Prateek Katare who worked under the guidance of Dr. Sai Siva Gorthi received the Gandhian Young Technological Innovation Award-2017 for developing a prototype of a Low Cost Automated Handheld Melamine Detection Device (for Testing Melamine in Milk).

Device_PhotoEven though a number of kits and devices are available for detecting common milk adulterants like urea, boric acid, water, sugar and detergents, there is hardly any portable device available for the detection of melamine. Till now, bulky instruments like Gas Chromatography (GC), HPLC, GC-MS and LC-MS are being used for detecting melamine which costs between 25 to 50 lakhs rupees, as well as requiring skilled personnel for operation. A fully automated handheld device to detect melamine from milk with integrated milk pre-processing step done using chemical dried cotton is developed. Melamine is finally detected through interference in Silver nanoparticle formation. Both the preprocessing and detection steps are innovative and patented. The cost of the device may be few thousand rupees which is almost 1000 times lesser than the price of existing conventional instruments. The developed device is user-friendly Low Cost Automated Handheld Melamine Detection Device (for Testing Melamine in Milk) which can give the level of melamine adulteration in ppm directly. Thus, the device not only tells the user whether the milk is fit for consumption or not but also gives the exact concentration of melamine in milk. This device fulfills the goal of taking melamine sensing to every household so as to protect every person from melamine adulteration.

Near Infrared Fluorescence Probes for Diagnosis of Alzheimer’s disease

K. Rajasekhar and Kavita Shah received the award for the research project Near Infrared Fluorescence Probes for Diagnosis of Alzheimer's disease. He carried his research work under the guidance of Prof. T. Govindaraju, Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), Bengaluru at a function held at Rashtrapati Bhawan on March 5.

K. RajasekharSelective detection and staining of toxic amyloid beta (Aβ) plaques found in the Alzheimer's disease (AD) brain is crucial for clinical diagnosis and monitoring of the disease progress. Herein, a coumarin-quinoline (CQ) conjugate-based molecular rotor type, turn-on near-infrared (NIR) fluorescence probe for selective and specific detection of Aβ fibrillar aggregates is designed. The probe CQ selectively binds to Aβ fibrillar aggregates over other toxic protein aggregates such as Tau, α-synuclein (α-Syn) and islet amyloid polypeptide (IAPP), and exhibit ~100 fold fluorescence enhancement with nanomolar binding affinity (82 nM). CQ effectively displace Thioflavin T bound to Aβ fibrillar aggregates and exhibit multiple binding sites on Aβ fibrillar aggregates which is extensively studied through fluorescence resonance energy transfer (FRET) and molecular docking. Remarkably, CQ unambiguously stains Aβ plaques in human brain tissue over its co-existing Tau aggregates, neurofibrillary tangles (NFTs), which are strongly associated in AD and in various tauopathies. This is a highly desirable attribute to distinguish AD from disease conditions caused by Tau pathology.

Prophylactic Transdermal Patch Against Neurotoxin Poisoning In Biological Warfare Situations

Subham Banerjee won the award for the research project Prophylactic Transdermal Patch Against Neurotoxin Poisoning In Biological Warfare Situations. He carried her research work under the guidance of Dr. Pronobesh Chattopadhyay, Dr. Animesh Ghosh Defence Research Laboratory, Tezpur Birla Institute of Technology, Mesra.

Drug-in-adhesive matrix type combinational prophylactic transdermal patch composed of eserine and pralidoxime chloride (PAM) against acetyl choline agonist (±)-anatoxin a neurotoxin poisoning was developed. Initially, a simple RPHPLC method was developed and validated for the s imult aneous de t e rmina tion and quantification of eserine and 2-PAM using UV detection. The method was validated as per ICH guidelines for validation of analytical procedures, and was applied for the routine analysis of these two drugs in fabricated transdermal patches.

Product DesignAdhesive matrix type transdermal patches containing eserine and 2-PAM were prepared by solvent casting method. The drug combinations were incorporated in adhesive matrix type system supported by a polyester film laminate backing membrane and attached to a temporary releaseliner. The dermal patches were having desired properties such as thin, circular, opaque, smooth, homogeneous, sticky, uniform, flat and flexible in nature. The drug release was sustained from all the formulations up to 72 h and following anomalous (non-fickian) diffusion and fickian release mechanism for eserine and 2-PAM, respectively. Optimized transdermal patch exhibited highest acceptable levels of tackiness with good adherence capacity and showed promising stability potential with respect to all points of analysis. From safety point of view, the optimized transdermal patch was safe for application to the skin with no dermal and mutagenic toxicity as well. Pharmacodynamic study proved that the optimized transdermal patch was effective against acetyl choline agonist (±)-anatoxin a neurotoxin poisoning. While pharmacokinetic study revealed that the systemic absorption of the drugs from the fabricated best optimized patch through the skin was sufficient enough to achieve pharmacodynamic efficacy.

STERI-FREEZ: Flash Freeze Sterilization

Saugandha Das including her team member Archit Devarajan won the award for the research project STERI-FREEZ: Flash Freeze Sterilization. She carried her research work under the guidance of Prof. Padma V. Devarajan Institute of Chemical Technology, Mumbai.

STERI-FREEZ_IMAGE 1Surgical site infections are one of the most common complications associated with surgery, with reported incidence rates of 2-20%. The problem is enhanced in rural or under-resourced clinics in under-developed or developing countries with about one-third of surgical patients getting infected, a rate which is nine times greater than in developed countries. Of the various causes, the use of contaminated medical instruments that have not been properly cleaned and sterilized directly contribute to surgical site infections with around 20 million post-operative patients infected. In absence of proper sterilization and disinfection protocols or methods these situations may become life threatening. Rural clinics in developing countries cater to 3 billion people worldwide, but do not have minimum provisions necessary to prevent post-surgical infections. Considering India has over 60% of the population living in villages, this is a serious problem and hence needs great attention.

STERI-FREEZ_Schematic IMAGE 2Thus STERI-FREEZ provides an AMAZINGLY SIMPLE on-site technology, which provides a ready to use, economic yet effective solution to the existing lacuna. This portable, cold sterilization device comprises of an insulator box housing a metallic vessel covered with a lid containing a green cryogenic biocidal mixture or Flash Freeze Elixir (FFE). Sterilization is achieved using a combination of biocides acting at subzero temperatures (-70 degree Celsius). Surgical instruments to be sterilized are kept immersed in FFE and removed just prior to use without leaving any toxic residue on the surfaces. Conventional methods of medical sterilization (autoclave, hot air, chemical and gaseous sterilization) require energy intensive instruments and long processing time while alternative sterilization techniques (Boiling in water) are not considered effective enough.

Targeted Theranostic Nanomedicines for Brain Cancer Therapy

Sonali Singh Doharey including her team member Rahul Pratap Singh, Poornima Agrawal won the award for the research project Targeted Theranostic Nanomedicines for Brain Cancer Therapy. She carried her research work under the guidance of Dr. M. S. Muthu, Prof. B. L. Pandey Banaras Hindu University, Varanasi.

Brain cancer is considered as one of the most devastating diseases because it is hard to treat and cure. Chemotherapy is the most common method for the treatment of different types of brain cancers. Unfortunately, the diagnosis and therapy of brain cancer are very unsatisfying because of the existence of the blood-brain barrier (BBB), which excludes more than 98% of small molecules and almost 100% of large molecules. Another obstacle in cancer therapy is to maintain the desired concentration of therapeutic agents and/or diagnostic agents at tumor site.

Sonali1The innovator developed targeted and controlled release nanomedicine systems including transferrin conjugated D-alpha-tocopheryl polyethylene glycol 1000 succinate (TPGS) micelles and transferrin / arginine – glycine – aspartic acid (RGD) conjugated TPGS liposomes (i.e., transferrin conjugated liposomes and RGD conjugated liposomes) to deliver docetaxel (DTX) and quantum dots (QDs), simultaneously through receptor-mediated active delivery for brain cancer therapy. Innovator demonstrated that RGD or transferrin TPGS decorated theranostic liposomes were highly effective in delivering desired concentration of therapeutic agents and diagnostic agents across BBB without any signs of brain damage or edema in brain histopathology. These advanced platforms can diagnose brain cancer at early stages, initiate first-line therapy, monitor it, and if needed, rapidly start subsequent treatments. In future, brain theranostics will be able to provide personalized treatment which can make brain cancer even curable or at least treatable at the earliest stage.

Revealed: Dual Functional Characteristics of Escherichia Coli Outer Membrane Protein Wzi And Its Implications In The Design Of Novel Antibiotics

Shivangi Sachdeva and Narendar Kolimi won the award for the research project Revealed: Dual Functional Characteristics of Escherichia Coli Outer Membrane Protein Wzi And Its Implications In The Design Of Novel Antibiotics. she carried her research work under the guidance of Dr Thenmalarchelvi Rathinavelan, Indian Institutes of Technology, Hyderabad. 

The emergence of multidrug resistance in bacteria is a major cause of infection and mortality worldwide. In Gram-negative bacteria, polysaccharide layers are one of the major virulent determinants that are involved in the evasion of host immune response as well as offers impermeability to antibiotics. Thus, inhibiting the capsular polysaccharide (CPS) biogenesis or surface exportation or its attachment to the bacterial surface may be an attractive strategy to generate avirulent Gram-negative bacterial strains. Here, the focus is on multidrug resistant Gram-negative Escherichia coli (E. coli), which is a common cause for urinary tract infections (including infections in the kidney), bloodstream infection, intra-abdominal infections such as peritonitis, skin and soft tissue infections, neonatal meningitis, diarrhea and food borne infections.

An E.coli outer membrane protein Wzi that acts as an anchor for CPS onto the bacterial surface (viz., a lectin) also exhibits a bidirectional passive water conduction property (viz., a porin). Such a dual functional role of Wzi was not realized earlier due to the occluded pore, a property that can be used to treat E. coli infections. It is observed that three water specific entry points across extracellular face regulate the water diffusion involving different mechanisms and a luminal hydrophobic plug governs water permeation across the channel. Thus, a drug molecule that can either interfere with the water conduction by Wzi or the attachment of CPS to Wzi may aid in reducing the bacterial virulence and make them susceptible to antibiotics or host immune response

A Novel Hybrid System for Textile Dye Waste Water Treatment

Bhaskar Bethi won the award for the research project A Novel Hybrid System for Textile Dye Waste Water Treatment. He carried his research work under the guidance of Dr. Shirish Hari Sonawane Department of Chemical Engineering, National Institute of Technology, Warangal.

In this project, Ultrasonic irradiation is used to initiate the emulsion polymerization to form hydro gel through the generation of free radicals as well as the uniform distribution of clay across the hydro gel polymer matrix. Recently, some attempts have been made to modify the properties of polymeric hydrogels by the incorporation of nano- or micro-particles of inorganic materials, such as montmorillonite, kaolin, mica, bentonite into the polymer networks. Hydro gels loaded with dispersed clays are a new class of composite materials which combine elasticity and permeability of the gels with high ability of the clays to adsorb different substances. The developed hybrid system for the treatment of dye waste water can be easily scaled up to industrial scale for the treatment of bulk volume of textile wastewater. It is due to its simplicity in design, less cost of material construction, low cost of operation and higher cavitation yield compared to the ultrasounic cavitation. The developed technology will be efficient for the removal of dye from aqueous medium with in short duration of operating time compared to the most of the conventional treatment techniques such as biological wastewater treatment as well as the single treatment techniques include adsorption, coagulation etc. This innovative technology mainly involves unique feature of both the degradation and subsequent absorption of dye organic pollutants from the waste water in a single set of unit.

Atomic power plant leak – Pallava Bagla

Dear all,

Greetings from Techpedia!

Inviting students working on material science, chemistry or any other discipline to suggest possible reason.

MUMBAI, Mar 19 (PTI): In a highly guarded Indian nuclear reactor complex, toughened radiation resistant pipes have contracted ‘small pox’. As a consequence, literally in a plot similar to a Bollywood thriller Indian scientists are burning the midnight oil to unravel the mysterious nuclear leak at the Kakrapar Nuclear Power Plant in Gujarat. This 21st century atomic pot boiler is actually unfolding through the hard work of scientists, who actually share a wall with the famous property where renowned Bollywood film star Raj Kapoor used to live.

Here, they are working over-time to find out the real cause of the cryptic leaks at twin reactors in southern Gujarat. To avoid any panic and any further accidents, the Indian nuclear watchdog – the Atomic Energy Regulatory Board (AERB) – has shut down the affected plants till the cause has been found. Nuclear experts say pipes, made from a rare alloy, have contracted what seems like ‘small pox’ and this contagion has spread all over the critical tubes in two Indian Pressurised Heavy Water Reactors (PHWR) at Kakrapar in Gujarat.And, to make the matters worse, after more than a year into the investigation, the teams of scientists really do not understand what has gone wrong.

It was on the morning of March 11, 2016, and as fate would have it exactly five years after the Fukushima reactors in Japan started exploding, unit number 1 of the 220-MW PHWR at Kakrapar developed a heavy water leak and had to be shut down in an emergency.

The indigenously built nuclear plant suffered a heavy water leak in its primary coolant channel and a plant emergency was declared at the site. No worker was exposed and no radiation leaked outside the plant, confirmed India’s Department of Atomic Energy. India’s nuclear operator, Nuclear Power Corporation of India Limited (NPCIL) said “reactor had shut down safely” and “no radiation leaked out”. It confirmed that safety systems had functioned normally.

The atomic thriller really begins when experts are trying to find out why a leak recognition system failed, in the first place it should have given an alarm. “There is a leak detection system in place in all PHWRs, but in this case it failed to detect the leak on March 11, 2016,” confirms AERB Chairman S A Bhardwaj. AERB speculates that the crack developed so rapidly that the electronic leak detection system just did not had the time to react. Subsequent investigations revealed that the leak detection system was fully functioning and the operator had “NOT shut it down” to cut costs.

Nothing in the core of a nuclear reactor can be done in a jiffy and several weeks after the first leak, initial probe using a specially designed tool revealed that four big cracks had formed on a coolant tube which led to the massive leak.

The discovery of the crack was only the beginning of the mystery, further efforts to find the root cause established that the outside of the tube, the part which was not exposed to high temperature heavy water, was also for some unexplained reason “corroded”.

This was a stunning discovery, since the outside of the failed tube was exposed only to high temperature carbon dioxide and there had been no recorded case of a similar corrosion having been seen on the outside of any tube. It is also very hard to access this part since the space was very tiny in the annulus.

The AERB then ordered that all the tubes made out of a special alloy of zirconium-niobium be checked on the outside, to their surprise, they discovered that the contagion of the “nodular corrosion” or what in layman’s language can also be described as “small pox-like” was very widespread in many of the 306 tubes. Tubes made from the same batch and used at other Indian reactors continue to operate faithfully, without corrosion. The needle of suspicion now pointed to the carbon dioxide, a gas known to be very stable in high radiation environments.

A further post mortem revealed that the Unit-2 which is twin of the affected reactor had also been affected by a similar leak on July 1, 2015 almost ten months before the Unit 1 had a sudden appalling failure in March 2016. Investigations into why the Unit-2 failed were ongoing but no conclusive result had been found. This literally back-to-back failure of two fully functional nuclear reactors befuddled the engineers.

Unrelenting in trying to find out the root cause, the AERB ordered that entire assembly and not just the affected tube be safely pulled out and brought to India’s foremost nuclear laboratory, the Bhabha Atomic Research Center (BARC) in Mumbai for detailed failure analysis. It is this laboratory located at Trombay in Chembur, in Mumbai that shares geography with India’s famous Bollywood Kapoor family. In addition, since India operates another 16 similar nuclear plants, a full-fledged investigation was carried out on the coolant channels of all atomic power plants and lo-and-behold the investigating team found that the “small pox” like corrosion was confined only to the two units that operated at Kakrapar.

While this gave a sigh of relief to the NPCIL but it increased the complexity on trying to unravel the true cause of the leaks at Kakrapar. Today, Bhardwaj says the investigators are wondering if the carbon dioxide used in Kakrapar may have been contaminated which caused the “nodular corrosion” on the outside of the pipes.

The source of the carbon dioxide was further back traced and it seems only the Kakrapar plant was sourcing its gas from a “Naptha cracking unit” and possibly it has some contamination of hydrocarbons. No conclusive evidence on the contamination has been forthcoming and forensic analysis is still under way.

As it turns out nuclear engineers are masters of book-keeping especially when ageing of equipment is concerned and a more detailed check in the history of the plants revealed that in 2012 two tubes had been extracted from the Kakrapar plant as part of routine maintenance and had been safely stored in a safe warehouse. When these were re-examined in 2017, the investigators were surprised that the “small pox” like corrosion on the exterior of the tube was not present.

This now makes the investigators suspect that something went wrong after 2012. Meanwhile, the AERB and the atomic energy establishment has also reached out to the vast global nuclear community to try and help resolve this mystery.

The global watchdog the International Atomic Energy Agency in Vienna and ten other global forums have been informed that a mysterious leak is dogging the Indian reactors at Kakrapar and if the global community could be of some help. The international community is as much at a loss in explaining the failures as are the Indian teams. India operates 18 PHWR reactors and over the years it has accumulated some 348 years of operating experience of these unique nuclear plants powered using natural uranium and in all these years, the Department of Atomic Energy asserts no radiation related death has taken place at any nuclear plant and no radiation has ever leaked out of the Indian PHWR’s.

In addition to it, 29 PHWRs are today functional in Canada, Argentina, Romania, China, South Korea and Pakistan and none have reported any issue like the ‘small pox like corrosion’ on any of its nuclear plants.

Bharadwaj says right now there are only hunches but teams at BARC are exposing the Zircalloy tubes to carbon dioxide spiked with various contaminants and they are being placed in a high radiation environment to accentuate the aging process to try and determine the exact cause of the two processes—“small pox like nodular corrosion and the development of cracks in the coolant tubes.” These could be linked or independent, says Bhardwaj, who feels that in the next few months, the root cause will definitely be deciphered till then the reactors will remain shut.

India currently operates 22 nuclear reactors with an installed capacity of 6,780 MW and hopes to ramp up nuclear output to 32,000 MW by 2032. Meanwhile, the continuing nuclear mystery is giving the vast Indian nuclear establishment and its atomic sleuths ‘nuclear jitters’.

a) non-uniform alloy itself, that is if alloy has been made in batches , then some batches may have had slight difference leading to patches like distortion; b) using an analogy of with disease in chickpea, where the fungus exists among roots of healthy plants also but disease manifest only in patches, probably because of changing c/n or c/p ( carbon phosph or nitrogen) ratio in those patches; the root cause may be more widely prevalent but problem may come in patches, c) is it possible that surface physics has to explain the problem.

Rotary ultrasonic Bone Drilling

Dr. Vishal Gupta received the award for the research project Rotary ultrasonic Bone Drilling. He carried his research work under the guidance of Prof. Pulak Mohan Pandey Mechanical Engineering Department, IIT Delhi.

Bone drilling is one of the steps in a typical surgical operation i.e. performed around the world for reconstruction and repair of the fractured bone. Fracture of bones is a common problem due to age factors, sports injuries, transport and industrial accidents, etc.There is always a necessity to minimize the magnitude of drilling force and torque during the bone drilling process. Thus, to minimize the rise in temperature, force and torque during surgical bone drilling process for more efficient and successful orthopaedic and trauma surgery. To attain the aforesaid, a new noble bone drilling method has been introduced recently named as RUBD. In the present research, a novel bone drilling technique i.e., rotary ultrasonic bone drilling named as RUBD has been successfully attempted to minimize the forces, torque temperature and microcracks during bone drilling. In order to perform the experimental investigations to find out change in temperature, force, torque, temperature and microcracks with RUBD using diamond coated hollow tool on bone, rotary ultrasonic tool assembly was designed and fabricated in house.

The drilling experiments were planned and carried out on porcine bones using design of experiments (Response Surface Methodology). Analysis of variance (ANOVA) was carried out to find the effect of process factors such as rotational speed, feed rate, drill diameter and ultrasonic vibrational amplitude on the force and torque. Statistical models were developed for the force and torque with 95% confidential interval and confirmation experiments have been carried out to validate the models. The results of microcracks by SEM revealed that RUBD process offered a lower force, torque, temperature and minimum microcracks, making it a potential process for bone drilling in orthopaedic surgery. It was also found that RUBD generated a much lower temperature, force and torque as compared to the CSBD.

A Virtual Reality (VR)-based Immersive Simulator for Endoscopy Training

Shanthanu Chakravarthy received the award for the research project "A Virtual Reality (VR)-based Immersive Simulator for Endoscopy Training". He carried his research work under the guidance of Prof. G. K. Ananthasuresh, Department of Biomedical Engineering, Indian Institute of Science, Bengaluru.

Virtual Reality (VR) together with haptics offers an immersive and flexible platform for training doctors in medical procedures. In this project, a VR-based endoscopy simulator together with the force-feedback system is developed. Endoscopy is minimally invasive and is used as an important diagnostic tool to detect abnormal tissues, ulcers, tumours, polyps, cancers, etc. Gastrointestinal (GI) endoscopy, including colonoscopy, is a complex procedure involving a high degree of hand-eye coordination.


These procedures are generally carried out by highly skilled clinicians. In order to practice endoscopy safely, a training system that does not involve patients is deemed important. VR-based training system developed in this work has many advantages. It is economical over a long run and usable any number of times; the training model can be changed and designed as per requirements including the incorporation of in-situ cases. It can be used for quantitatively assessing skill as recorded training sessions can be used for identifying mistakes. The developed endoscopy simulator also has many novel features. It consists of a three Degree of Freedom (DoF) haptic device, force models for real-time interaction, computer graphic models for visualization, and an ins t rumented endoscope for reali s tic interactions.Shanthanu Chakravarthy3

All the units of the simulator are uniquely integrated to provide immersive endoscopy s imulation. The device is kinematically designed to mimic real endoscopy. Furthermore, the endoscopy simulator developed in this project has the potential for extension to other interventional procedures such as colonoscopy, bronchoscopy, and endovascular training.

White Light Emission from Vegetable Extracts

Dr. Vikram Singh received the award for the research project White Light Emission from Vegetable Extracts. He carried his research work under the guidance of Prof. Ashok Kumar Mishra, Department of Chemistry, Indian Institute of Technology, Madras.

White light emission (WLE) is generated from natural dyes extracted in the laboratory using a green and simple procedure. The optimized mixture of vikram singhtwo suitably chosen plant extracts using acidic ethanol, aided by a FRET cascade from polyphenolics to curcumin to anthocyanins, generates almost pure white light, with CIE values of (0.35, 0.33) in solution, (0.26, 0.33) in gelatin gel and (0.33, 0.25) in PVA film. The colour temperature of the WLE is conveniently tunable by simply adjusting the concentrations of the component emitters. The primary emitting pigments responsible for contributing to WLE are pol yphenol s and antho c y anins f rom pomegranate, and curcumin from turmeric. WLE from such cheap and nature friendly resources could be important in the context of lighting and sensing application. It would be interesting to see if such system can be used as dyes for tunable dye laser applications. Given the vast number of excellent natural fluorescent dyes obtainable from renewable biosources, approaches similar to the present could lead to a more extensive range of low-cost and efficient WLE biomaterials with ease of adjusting colour temperature, which will obviate more expensive alternatives currently being pursued.

IIT Kanpur: Students felicitated for developing Braille slate ~ indiatoday.in

Students of the Indian Institute of Technology-Kanpur (IIT-K) were given the Gandhian Young Technological Innovation Award-2017 for developing a prototype of a Braille slate called 'Anubhav' at a function held at Rashtrapati Bhawan on March 5.

Gandhian Young Technological Innovation (GYTI) Awards celebrates the spirit of student innovation in all the fields of engineering, science, technology and design through extremely affordable/frugal solution or the ones pushing the technological edge.

As per an HT report, there were 2,715 nominations from 308 institutions and universities from 27 states and two Union Territories across 54 different subject disciplines. This year, 22 innovations were selected for the award and another 17 for appreciation. 

First device to help visually impaired read and write simultaneously:

The idea was to develop 'Anubhav' was initiated by Sachin NP and Vimal Chandru, design programme students who worked under the guidance of Prof Shantanu Bhattacharya. According to them there was no single device that could help the visually impaired read and write simultaneously before this.

Sachin, who graduated from IIT-K and is currently working with a German company, said: "The award is a reward for our hard work. It will inspire us to do more innovation and bring about a change in society. Technology should be used for the betterment and welfare of society."

 "So we thought of sorting out the issue. The idea was to make a single device that can perform the functions of both the Braille slate and the Taylor's board," said Sachin and Vimal.

87165 The Braille slate has two polymer-based pads hinged to one side, a single row of metal stencil with Braille cell patterns etched on it and an ergonomic stylus with a hollow cylindrical tube.

'Anubhav' consists of cells with raised dots arranged on a slate and a stencil that slides down vertically from one row to the other. Using the hollow-tube stylus, the raised dots can be embossed on a paper placed between the pads. 8041IMG_20160503_164708

"The device has been tested with visually impaired children in Kanpur (Andh Vidyalaya students), and the results have been very encouraging," claimed Sachin, adding, "This project has been in progress for the past one year. 'Anubhav' was the result of thorough research. Now, we are trying to approach the state government to make this product available in the market."
