Buzzing Band For Hearing and Speech Impaired

Student of Shri Vishnu Engineering College for Women, Andhra Pradesh , Saka Naveena, Panchakarla Sevya Naga Priyanka, Khande Dhana Lakshmi , Murikipudi Bindu Madhaviwon the award for research work of Buzzing Band For Hearing and Speech Impaired. They carried their project work under guidance of Prof. Ravuri Viswanadham, Prof. K. Padma Vasai .

Communication is part and parcel in every man’s day to day life. But it causes several difficulties for a person who is hearing impaired or speech impaired. Even though sign language replaces general talks for them, it fails to draw the attention of the person who is distant from the speaker. This situation causes lack of interaction among the hearing impaired students and the teacher. To overcome the problem faced by students in classroom and enable him to engage with teacher or with distant student a device that supports mass communication is needed. So to suit this requirement, the proposed solution is a device called “BUZZING BAND”. The key feature of this device is to provide one to many communications (between teacher and all students in class) in addition to one to one communication”. In order to achieve the above said communications RF Technology is preferred. Communication from one device to another is easily achieved by using RF technology. The input to the buzzing band is given with the help of a button. The button is connected to the Arduino nano to which an RF transmitter is interfaced. On the receiver’s side there will be an RF receiver which is interfaced with arduino along with a single digit display and a micro vibrator motor. The future innovation uses programming techniques so that signal is sent to various transceivers with a small time delay between each transmission to a single transceiver.

Development of Smart Wearable Body Warmers Using Graphene Coated Conductive Fabrics

Student of Indian Institute of Science, Bangalore, Nagarjuna Neella, Vaishakh Kedambaimoole won the award for research work of Development of Smart Wearable Body Warmers Using Graphene Coated Conductive Fabrics . She carried her project work under guidance of Prof. K. Rajanna, Prof. M. M. Nayak, Prof. N. S. Dinesh.

Body warmers are generally used to combat cold weather conditions across the globe. Also, they find use in biomedical i.e. electrotherapy treatments, medical blankets for patients to maintain their body temperatures and military worn jackets for soldiers in the defense forces. Moreover, some of the flexible beds employ air cushion which serves as good heat insulator to retain heat but they do not function as body warmer. Additionally, blankets/jackets made up of pure woolens/pashmina from cashmere, caprinae family animal’s fiber may prove to be good body warmer, but quite expensive and hence not affordable for middle class person/common man. Also, no control of warming is available with such garments. Warmers presently available in the market consists of fine wires/films made of metal alloys, ITO and Ga doped Zinc Oxide woven to form high resistances and consumes higher power than proposed RGO. Today’s rapid growth and progress of work in the area of wearable miniaturized electronic devices using nanoscience and engineering concepts have led to the new generation of device technology. Nanomaterials used in elements designed for creating flexible electronics/electrical and fabrics/garments due to their unique properties i.e. large SA/V and dimensionality. Commercial heaters have disadvantages: complicated fabrication and monotonous which leads to special machinery, opacity, heavy and rigidity, intolerance to acid/base, fragile, lower heating efficiency and also bulky, expensive, limited flexibility. So, looking for innovative devices with effective body warming functionality, compatible/flexibility, lower energy consumption & manufacturing costs. Presently developed/invented RGO based cloth fabrication is straight forward either by dipping/pouring solution onto the cloth and curing it suitably. Therefore, our aim is to overcome the above-mentioned drawbacks, wherein the invention provides heating device formed into required shapes, corrosion free, flexible and biocompatible.

Nano-biosensor And Methods For Detecting Potassium Ion Concentration

Students of Junagadh Agricultural University, Junagadh, Jaymin Kanubhai Jadav, Khyati Jagdish Rathod won the award for research work of Nano-biosensor And Methods For Detecting Potassium Ion Concentration. They carried their project work under guidance of Dr. B. A. Golakiya.

The invention’s outcome will help in determination of potassium deficiency from the standing crop even if the plant is not showing any visible deficiency symptoms. Potassium deficiency levels can be determined at any stage and which will help to prevent its further progress. If on determination, the plant potassium content, is found close to the threshold deficit level or deficient; potash fertilizer which is a readily available form of potassium can be applied to the field crops to recover them from the deficiency and prevent the overall yield losses. 

The invention belongs to electrochemical analysis of activity of ions in sample via a potentiometric sensor. This makes it a field portable and a unique class of biosensors that may be very useful in agricultural fields. The sensor is based upon screen printable technology, where a screen printed electrochemical cell is modified using a biomimetic component say; valinomycin- an antibiotic, one of the most potent potassium (k+) ion carrier to function as ion selective electrode. For measuring ion activity in the mentioned plant sap samples, the Ion-Selective Electrodes (ISE) are without any competition. The present research is aimed to solve the problem of detection of potassium deficiency prior as Hidden Hunger i.e. early detection to the actual morphological/visible symptoms appears in the crop plants. If the plant potassium deficiency can be determined before the symptoms, then preventive measures can be taken recover the plant health such applying potassium based fertilizer. This will also control the unnecessary usage of fertilizers, improve soil health and reduce water and atmospheric pollution ultimately reducing the cost or expenses of farming.

New generation periscope fruit picking device

Students of Birla Institute of Technology & Science, Pilani, Hyderabad, Tania Dutta won the award for developing a prototype of New generation periscope fruit picking device. She carried her project work under guidance of Dr. P Yogeeswari.

The estimated extent of annual post harvest losses are: Fruits, about 30 per cent valued at Rs 13,600 crores and for vegetables about 30 per cent valued at Rs 14,100 crores.

The most probable cause for the losses encountered is the untimely harvesting before proper maturation and the harvesting of damaged fruits along with the good ones and storing them together.The post harvest losses can be minimised to a great extent if the harvesters can see the condition of the fruits on the trees before picking them. Thus, I have come up with a design optimised modified tool structure. We have incorporated the idea of a periscope inside a fruit picker in such a way that it gives a complete view of the fruit so that the harvesters can decide if the fruit has ripened or not and pick accordingly. The device also has a focusing and zooming lens set-up for a better image at the end. The rod in the device are placed in a telescopic fashion. 
This allows flexible height adjustment of the rod according to the fruit height on the tree. The design is simple, convenient to use, does not require much technological knowledge, very cheap, easy to manufacture and provides a great loss minimisation in the long run. This product is mainly targeted to help the poor farmers who are still used to with the traditional old methodologies and equipments and have not yet been exposed to the highly advanced technical automated robotic machineries on which current researches are going on abroad.

Eco-Friendly Water Retention Natural Polymer

Students of College of Technology and Engineering, Udaipur, Narayan Lal Gurjar, Shashi Pratap Singh Shekhawat, Ankit Jain won the award for research work of Eco-Friendly Water Retention Natural Polymer. They carried their project work under guidance of Dr. Shailendra Mohan Mathur.

As we know our country is agricultural depending economy and big part of our economy is depends on the agriculture. But production in agriculture is proportional to water availability.

In India 266 districts, in 11 states declared drought affected. The average food grain production between 2010-2011 and 2014-2015 is 255.59 million tons, while in 2015-2016, it is estimated to be at 253.16 million tones. More than 70% districts drought affected in 8 states. The data shows scarcity and unavailability of water causes too many losses. So we tried to create something helpful to retain water for long time, and in this trying we are successful to create a polymer named “Eco-Friendly Water Retention Natural Polymer”. Keeping in mind all the conditions of our country and our farmers we designed this product at low cost with much more efficiency. This polymer is working on properties of SAP. SAP have properties to absorb water of quantities of their own weight. It has more capacity to store water for long time. On testing of our product we found it may retain water for 4 to 6 weeks that means crops irrigated at intervals of 2 to 4 days are now can be irrigated at 7 to 8 days with less water consumption. Therefore, finally farmers can get more crop production in low water consumption. Our natural polymer is designed by use of waste material like banana peels and peepal barks with gel. As all the ingredient used are biodegradable, so our designed product is also biodegradable and completely pollution free i.e. it is easily mixed with soil and does not create any problem in the future.

3D-NuS: A Web Server for Automated Modeling and Visualization of Non-Canonical 3- Dimensional Nucleic Acid Structures

Students of Indian Institute of Technology Hyderabad, L Ponoop Prasad Patro, Abhishek Kumar, Narendar Kolimi won the award for research work of 3D-NuS: A Web Server for Automated Modeling and Visualization of Non-Canonical 3- Dimensional Nucleic Acid Structures . They carried their project work under guidance of Dr. Thenmalarchelvi Rathinavelan.

The inherent conformational flexibility of nucleic acids (DNA, RNA etc.) facilitate the formation of a range of conformations such as duplex, triplex, quadruplex etc., which play crucial roles in biological processes such as mismatch repair, replication, recombination, transcription, translation, gene regulations etc. These unconventional base pairing and structural conformations on DNA/RNA structures at different sequence contexts also induce abruptions in normal cell function which can lead to deformities and diseases (cancer, fragile X syndrome, etc.).

 To understand the role of these unusual nucleic acid structures in aforementioned biological phenomena and diseases, structural details at atomic level is indispensable. But, experimental methods (such as XRAY crystallography, NMR etc.) are not always successful in determining structural details and are very expensive. Further, structural insights about nucleic acid triplexes, which are generally not tractable to structure determination by X-ray crystallography or NMR techniques, are essential to establish their biological function(s). A web server, namely 3D-NuS (http://iith.ac.in/3dnus/), has been developed to generate energy minimized models of 80 different types of triplexes, 64 types of Gquadruplexes, left handed ZDNA/RNA duplexes, RNADNA hybrid duplex along with inter- and intramolecular DNA or RNA duplexes comprising a variety of mismatches and their chimeric forms for any user defined sequence and length. It also generates an ensemble of conformations corresponding to the modeled structure. These structures may serve as good starting models for docking proteins & small molecules with nucleic acids, NMR structure determination, cryo-electron microscope modeling, DNA/RNA nanotechnology applications and molecular dynamics simulation studies. The operational milestones that would be accomplished in future include generation of aforementioned structures with modified nucleic acids such as PNA and LNA, intra-molecular triplexes, complex duplexes and models with user defined structural parameters.

Performance Evaluation and Process Optimization for Production of Ready-to-Eat Therapeutic Food Paste in Pilot Scale Unit

Students of Indian Institute of Technology Kharagpur, Rakesh Kumar Raigar, Danie Shajie A won the Appreciation award for research work of Performance Evaluation and Process Optimization for Production of Ready-to-Eat Therapeutic Food Paste in Pilot Scale Unit. They carried their project work under guidance of Dr. H N Mishra.

Severe Acute Malnutrition (SAM) is an important cause of morbidity and mortality in children below five years of age in India, where 8.1 million children are estimated to suffer from SAM. To combat this stumbling block, an indigenously developed readyto-eat therapeutic food (RTE-TF) is the need of the hour, catering the prerequisite of energy dense and nutrient rich ready-to-eat product containing defined calorie and essential nutrients which would be storage compatible, culturally acceptable; easy to administer; control and deliver at low cost for SAM children. A GMP/GHP compliance PLC controlled pilot scale unit has been commissioned in the Agricultural and Food Engineering Department at IIT Kharagpur aligning with the Make in India vision in treating SAM at community level with financial support from Department of Biotechnology, Government of India, New Delhi for the production of RTE-TF.

 Five RTE-TF formulations were developed using locally produced raw material and fortified with micronutrients. A peanut based formulation was processed for the performance evaluation and optimization of major equipment installed in the pilot scale unit. The material and system parameters for primary processing (batch operations) like roasting, deskinning, grinding etc. and PLC based continuous processing (viz. grinding, mixing & homogenizing) were optimized along with the standardization of PLC based clean-in-place (CIP) sanitization system. Physico-chemical, safety and nutritional characterization of the RTE-TF produced in the pilot scale unit was done and complied as per the norms defined by World Health Organization for SAM. The pilot scale process will reinforce the liability for sustainable production of RTE-TF paste which would aid in management of SAM in children in our country.

A Non-contact Optical Device for Online Multiplexed Monitoring of Diseases of Military Importance in Fragile and Conflict-Affected Settings

Students of S.N.Bose National Centre for Basic Sciences, Probir Kumar Sarkar, Aniruddha Adhikari, Animesh Halder, Soumendra Singh won the award for developing a prototype of A Non-contact Optical Device for Online Multiplexed Monitoring of Diseases of Military Importance in Fragile and Conflict-Affected Settings. They carried their project work under guidance of Prof (Dr). Samir Kumar Pal .

Jaundice, Anaemia and Hypoxia, the three intimately interrelated health problems in military services particularly in fragile and conflict-affected settings take care of significant preventable casualties. These trio also proved to be the major cause for neonatal and maternal mortality in developing world. On the other hand, conventional gold-standard detection strategy through invasive blood sampling has several drawbacks for neonates and is redundant in fragile and conflict-affected settings. Thus a low cost and robust strategy for diagnosis of these diseases in all adverse conditions is of outmost importance to countries like India where huge number of military personnel are deployed in adverse geographical conditions along the border area and where under-5 mortality rate is alarmingly high. We, developed prototype of a noninvasive, non-contact, affordable, easy-to-use, point-of-care reflectance spectroscopy based device for measuring all three parameters at one go based on the spectral signature of bilirubin, hemoglobin and oxygen saturation from the vascular bed lying under conjunctiva (white portion) of eye. As conjunctiva is white independent of race, age or skin color, the device is useful to all. The indigenously developed software makes the device compatible to e-healthcare with possibility of online monitoring through cloud computing. Thus, this strategy will be extremely helpful in critical/low resource conditions like battle field and high altitude border regions for regular routine health check-up of army people who always devoted their life to protect the nation. The innovative noncontact, low-cost technique is expected to have importance in monitoring jaundice, anemia and hypoxia in developing / underdeveloped countries, where the inexpensive diagnosis with non-experts manpower is obligatory.

3D bioprinted skin scar model for drug and cosmetic testing

Students of Indian Institute of Technology Delhi, Shikha Chawla, Aarushi Sharma won the award for research work of 3D bioprinted skin scar model for drug and cosmetic testing. They carried their project work under guidance of Dr. Sourabh Ghosh.

Current anti-scar cosmetic products or medicines are not effective enough due to poor understanding of scar pathogenesis. Results of pre-clinical trials on animals do not always extrapolated to humans . Moreover, pharmaceutical companies are facing a major jolt due to European Union ban on animal testing of finished cosmetic products/ingredients (European Union Council Directive 76/768/EEC).

International Cooperation on Cosmetics Regulation is strongly encouraging development of alternatives for drug testing on animals due to ethical concern, to reduce or eliminate the use of animal models. Hence, there is an urgent need for a human cell-based in vitro engineered tissue models to screen drugs/cosmetics for the prevention of scar. Since past 50 years, many international researchers/industries tried to develop tissue engineered skin for transplantation. But tissue engineered skin received limited success in human clinical trials. Uniqueness of our approach is to develop a relatively simpler, human cellbased in vitro tissue engineered skin model that could 1) be used for rapid screening of anti-scar drugs/cosmetics and 2) help to extend our understanding of the cellular signaling pathways. Our model could recapitulate several hallmarks of scar tissue: (1) fibroblasts to myofibroblasts transition and expression of α -SMA; 2) contraction; 3) excessive collagen and reduced elastin secretion; 4) fibrotic ECM protein expression (SPARC and Tenascin); 5) low MMP secretion and 6) involvement of TGF-β/SMAD and Wnt/β-catenin pathways. To the best of our knowledge, no such in vitro models have been reported, hence it is getting major attention of national/international level news media and pharmaceutical companies.

Road Accident Detection using Perceptual Attributes of Video

Student of Indian Institute of Technology Kanpur, Dr. Sinnu Susan Thomas won the award for research work of Road Accident Detection using Perceptual Attributes of Video. She carried her project work under guidance of Prof. Sumana Gupta and Prof. K S Venkatesh.

According to Annual Global Road Crash Statistics, nearly 1.3 million people die in road crashes every year, on average 3,287 deaths a day. Road accident detection and vehicle behavior analysis is of great interest to the research community in intelligent transportation systems. Surveillance cameras are ubiquitous on the roads and capture videos round the clock. The enormous data collected by cameras may be time consuming and laborious to scrutinize the occurrence of an accident scenario present in the videos. There is a need to reduce the redundant nature of video so that its contents become succinct using video summarization techniques. The project presents perceptual video summarization techniques to enrich the speed of visualizing the accident content from a stack of videos. The problem of vehicle analysis is formulated as an optimization problem. The results establish the versatility of the proposed summarization model.

This model is formulated using cost function based on the change in the appearance of perceptual features such as motion, color, shape, and size. A selective minimization of the cost function leads to an appropriate video summarization of the event. The experiments were conducted for different types of collision such as head-on collision, rearend collision, single-vehicle collision and intersection collision and summarized the events prior, during, and subsequent to the accidents. The reduction ratio achieved is small and true positive detection is higher compared to the conventional methods. The model used for this project can be used for various surveillance purposes

Window Solar Cooker

Students of Indian Institute of Technology Bombay, Avinash Prabhune won the award for research work of  Window Solar Cooker. They carried their project work under guidance of Prof. B K Chakravarthy.

The LPG price hikes every month triggered the thought on Solar Energy which could be a clean and abundant source of energy. There are many types of solar cookers available in the market, but they are not that efficient. Each one has its own pros and cons. In a rapidly urbanizing India, the user segment this product is targeted towards are the people who live in high rise buildings because they don’t have space to use solar cooker and the old solar cookers fail to match their fast-paced life style. For using present type of solar cookers, the users need to have open space where they will get continuous sun light and the users need to track the sun all day.

All these usability issues are the reason why urban users are not willing to consider this as an alternative to conventional cooking methods. This new kind of solar Oven will be mountable in the window or wall like a window AC, while facing towards south where sun is available all year round. Thus the accessibility becomes very easy from inside the house itself and the users need not go out. The cylindrical form provides uniform sunlight all day long. The ‘Dabba’ perception about the box-type of solar cooker has been broken by this new design. The efficiency has been improved and the time taken for cooking is drastically reduced, as compared to any other kind of solar cooker.

Magnetic tool for nano finishing the holes, vertical and horizontal surfaces

Student of Indian Institute of Technology Delhi, Girish Chandra Verma won the award for research work of  Magnetic tool for nano finishing the holes, vertical and horizontal surfaces. He carried his project work under guidance of Prof. Pulak Mohan Pandey.

The developed tool is based on MAF principle for polishing holes, blind holes, grooves and vertical surfaces. The tool developed in the present work consists of five main components, which are two cylindrical magnets (having magnetic flux density of 0.452 T), a mild steel piece, a copper casing, and an upper head made of mild steel. In the developed tool the magnets were arranged in such a way that, similar pole of both the magnets faces each other. Due to this the magnetic lines of force from both the magnets get directed to radial direction. Using this concept of similar pole facing each other; a high magnetic flux density 0.8 T is achieved around the circumferential area of mild steel piece. The developed tool also produces variable magnetic flux density so that material of different hardness can be finished. For obtaining a variable magnetic flux density, the gap between the upper magnet and ferromagnetic piece is altered with the help of nut and bolt arrangement provided on the upper piece of copper casing and upper head. The size of the developed tool can also be modified by using different sizes of magnets and casing, which can be used to finish hole of different sizes. Experimentation on SS304 stainless steel pipe (with initial surface roughness of 541nm) at an optimized condition resulted in a surface finish of 56 nm. The obtained SEM (scanning electron microscopy) images of finished and unfinished surface have showed that all the scratch marks were removed and finished surface was obtained.

Feasibility Study of Wireless Power Transfer Using Metamaterial

Students of Indian Institute of Technology Guwahati, Amit Kumar Baghel, Shashank Satish Kulkarni won the award for research work of Feasibility Study of Wireless Power Transfer Using Metamaterial. They carried their project work under guidance of Dr. Sisir Kumar Nayak, D. Senthil Kumar.

Wireless power transfer (WPT) is the method to transfer power from the source to load without cables or wires started way back in 1903 by Dr. Nicolas Tesla. Nowadays this technique is being used in many applications such as biomedical transplants, UAVs, mobile chargers, electric vehicle charging, antennas etc. But the major problem with the WPT is the decrease in the efficiency as the distance is increased. In near field, the strength of the field varies inversely as the square of distance and cube of distance for far field. One of the novel ways by which we can increase the intensity of field, thus power transfer is with the help of meta-material.

They are manually engineered with negative refractive index and help in beam focusing. It can act as a super-lens. My innovation is about increasing the efficiency of far-field WPT using metamaterial. The metamaterial pattern is made on the 1. 6 mm thick double-sided FR4 sheet (dielectric constant 0.02) having 0.017 mm thick copper plating on both side of the sheet. A total of 40 arrays having 8 unit cell in each is placed at an optimized distance from the aperture of the proposed horn antenna (Tx antenna). The electric field at the distance of 6 m is measured using the D-dot sensor. The receiver antenna is 2×2 patch antenna having RF to DC conversion schottky diode and matching circuit. To charge the batteries of the cellphone (2900 mAh, 3.8 V), the zener diode with RC filter is placed after the matching circuit. An increase in twice the electric field , thus the received power is seen with the proposed antenna and meta-material.

A Novel low cost Polyvinyl alcohol-Nafion-Borosilicate membrane separator for microbial fuel cell treating distillery wastewater

Students of Indian Institute of Technology Khragpur, Bikash Ranjan Tiwari, Md. Tabish Noori won the award for research work of A Novel low cost Polyvinyl alcohol-Nafion-Borosilicate membrane separator for microbial fuel cell treating distillery wastewater. They carried their project work under guidance of Prof. Makarand Madhao Ghangrekar.

Microbial fuel cell (MFC) are bioelectrochmical systems which convert the organic matter present in the wastewater to electricity with the aid of biocatalytic acitvity of a specific group of microorganism i.e. electrogens. MFCs presents a promising solution to both waste removal as well energy generation simultaneously. The high manufacturing cost of MFC is a major hurdle in the path of field scale application. The membrane cost ($1600/m2) alone accounts for around 35% of total MFC capital cost.Hence, development of low cost membranes can ease the path for real world application of MFCs. In the present study, a composite membrane was developed from borosilicate glass incorporated with polyvinyl alcohol (PVA)-Nafion matrix. While utilizing acetate based synthetic wastewater, MFC with PVA-Nafion-Borosilicate membrane exhibited maximum power density of 6.8 Wm-3 and it was comparable with MFC using commercially available Nafion 117 (7.1 Wm-3) membrane separator. Moreover, the method of preparation is simple and cost of the novel membrane is 11- folds lower than commercially available Nafion 117. The study was further extended by utilizing the MFC with the newly developed membrane for distillery wastewater treatment. effluent generated from distilleries are characterized by their high COD and BOD content and acidic pH which can cause serious environmental problems if not properly treated. The MFC was capable of efficiently degrading organic matter present in distillery wastewater in the range of 54.5 – 64.25% along with generating a maximum power density of 4.3 Wm-3. This study demonstrates a novel, low cost, easily synthesizable membrane which was successfully used for treatment of distillery wastewater treatment in MFCs.

An Alternative Technology to Produce Biomass-Based Food Grade Flavors, Fuels and Value Added Chemicals

Students of Indian Institute of Technology Delhi, Shelaka Gupta, Md. lmteyaz Alam, Tuhin S. Khan, Ejaz Ahmad, Fatima Jalid won the award for research work of An Alternative Technology to Produce Biomass-Based Food Grade Flavors, Fuels and Value Added Chemicals. They carried their project work under guidance of Prof. M. Ali Haider.

State-of-the-art technologies applied today to convert biomass into high value fuels and chemicals are based on multi-step catalytic transformation steps, which are difficult to commercialize. Here, as an alternative, a technology (TNEW) based on integrated bio and chemo-catalytic reactions is developed, to carry out the desired conversion of biomass in fewer steps, giving higher product yield. In TNEW, 6- amyl-alpha-pyrone (6PP) is identified as a potential biomass-derived platform chemical. 6PP is produced from the fermentation of waste biomass using Trichoderma species and catalytically converted into 2-nonene-4-one, hydric alcohol, δ-decalactone (DDL) etc., under relatively mild processing conditions. While DDL and 2-nonene-4-one showed direct applications as food flavor and aroma, other products may be used as precursors for polymers, pharmaceuticals and hydrocarbon fuels. Three Indian patent applications related to the commercial development have been filed. Socially, the simplistic nature of our technology is expected to have a wider impact on rural economy and environment. For example, at present large volume of waste lignocellulosic biomass is burnt in the national capital region of India, creating air pollution at alarming levels. Farmers burning such valuable biomass may choose to utilize TNEW and ferment the waste biomass directly to produce 6PP which can be subsequently converted to produce high value chemicals. To the best of our knowledge, this is the first time in our country a novel biomass-derived platform chemical is introduced which is different from the top-12 chemicals proposed by the US Department of Energy. This will add into the portfolio of a futuristic bio-refinery, providing a renewable and sustainable solution.

A multipurpose low cost biological air purifier

Students of Dr. D.Y. Patil Vidyapeeth, Pune, Neeta Ganesh Wagle, Priti Prabhakar Yewale won the award for developing a prototype of  A multipurpose low cost biological air purifier. They carried their project work under guidance of Dr. Neelu Nawani.

In recent years, air pollution has become a major threat to survival of mankind. Looking at the current problem, biological air purifier would deliver a smart solution to circumvent the problem of indoor and outdoor air pollution caused due to motor vehicles, occupational exposure, cigarette smoke and industrial emissions in particular and will also focus on utility of the air purifier in reducing exposure of public to air pollutants. The team has designed and fabricated a prototype of biological air purifier- “Biosmotrap” comprising of compact carriage assembly with replaceable adsorbent packed in biodegradable pouches or wrappers by means of support meshes and clamping structures and further attached to vents, exhaust or any outlet from where gases are released in any process. The microbial biomass and/or natural bio-materials were employed in the form of solid porous material as an adsorbent. The adsorbent is configured to adsorb air pollutants like smoke, aerosols, particulate matter, flue gases, soot or other air pollutants. The shelf life of adsorbent depends on the concentration of air pollutants from the source point. It reduces the levels of organic as well as inorganic pollutants from the air. The onetime cost of carriage assembly is incurred with each biological air purifier. It can be reused for longer duration until it breaks or needs repair. Also, with the use of recyclable adsorbent material the cost per air purifier is lowered by making it affordable to everyone. This lowers the overall cost of maintenance when compared to conventional air purification technologies and increases its utility by encouraging public at large to use such devices. The fabricated prototype is easy to operate, cost-effective, recyclable and environmental friendly.

Roll Pure – Rolling Water Purifier

Students of Indian Institute of Technology, Madras ,Ramesh Kumar, Swathy Ravindran won the award for developing a prototype of Roll Pure – Rolling Water Purifier. They carried their project work under guidance of Prof. Thalappil Pradeep.

In rural India, people, mostly women and kids, still carry water on their head or shoulder from available local water bodies, sometimes even carrying non-potable water. According to a survey carried out in 2012 by National Sample Survey Office (NSSO), about 54% of women from rural areas travel between 200 meters to 5 kilometers, average 20 minutes a day and additional 15 minutes to fetch water, amounting to 27 days of wages per annum for an individual. According to NSSO statistics, less than 10% of rural Indian household has the facility to treat water at home before its end use. This whole process results in physical fatigue of women and waterborne diseases such as diarrhea, anemia and child mortality hence many resulting postaffects. Roll Pure – Rolling water purifier provides solution for the overhead transportation of nonpotable. A user (women) can fill 40 liters of raw water from any water source (i.e. river, canal, pond, municipal hand-pump or tap etc.) and roll it to home, with minimum time required for transportation without any physical fatigue. To make fed water potable, a 1) hand-operable pump and 2) modular geo-genic contaminant specific cartridge is used. Modular geo-genic contaminant specific cartridge has 1) biocidal material, 1000 times biocidal then silver nanoparticles to kill bacterial and viral contaminants and 2) nano-composite material to remove soluble chemical contaminants. To get chemical and biological contaminant-free water with high output flow rate, a pressure differential is generated using bellow pump. Roll Pure can provide chemical and biological contaminant free water to India’s rural BoP with minimal transportation effort and without any power.

Point of Care Nano Diagnostic Kit for Brucellosis

Students of Institute of Chemical Technology, Mumbai, Rohit Shivaji Pawar, Swati Suhas Vyas won the award for developing a prototype of Point of Care Nano Diagnostic Kit for Brucellosis. They carried their project work under guidance of Dr. Vandana B. Patravale.

Brucellosis, a neglected global zoonotic infectious disease is transmitted to humans through consumption of unpasteurized dairy products and direct contact with afflicted animals. Presence of bacteria such as Brucella spp. in dairy products is an immense risk to public health. The innovation herein describes the development of immunochromatographic diagnostic kit (ICDT) based on fluorescence silica nanosensors that serves as a promising nanodiagnostic approach for detection of intact Brucella antibodies in nonserological samples eliminating painful blood collection procedures. Point of care immunoassays are rapid as they can quickly screen various samples in relatively shorter duration, are sensitive, specific, offer great advantage in accurate and fast diagnosis of infectious diseases. We have fabricated a point of care rapid diagnostic assay that employs fluorescent, micellar silica nanosensors conjugated with lipopolysaccharides (Indian patent application 3183/MUM/2013) capable of specifically detecting Brucella IgG antibodies in non-serological samples of afflicted animal (milk, urine, saliva) and human samples (urine, saliva).

 

The developed kit holds its industrial application in agricultural , biotechnological and pharmaceutical arena. We have successfully fabricated and evaluated the aforementioned kit. The developed ICDT provides a rapid, reliable, point-of-care, accurate and reproducible results in accordance with PCR and ELISA results with high sensitivity and specificity.Additionally, well defined antigenic components and surface biomarkers of various disease causing microbes can be broadly incorporated within the purview of this technology for accurate and rapid detection of suspected bovine pathological conditions, and can largely enable rapid field testing that can be implemented in farms and food Industry. Since the developed technology is novel, cost effective yet scalable; it fits “Make In India” initiative to foster innovation, enhance skill development, create intellectual property and generate revenue.
