Title: 3D Paper-based milk adulteration detection device

Due to the high demand and limited supply, milk adulteration is widespread in developing countries. In this study, a low-cost, simple-to-use device is developed using the colorimetric approach to detect food adulterants instantly. The developed 3D paper-based microfluidic device can simultaneously detect several contaminants by utilizing a tiny volume of the liquid food sample (say milk).
The developed device has been successfully tested to detect common adulterants in liquid food in a single test (as defined by the Food Safety and Standard Authority of India, FSSAI). Seven adulterants are detected in milk samples simultaneously with high specificity evaluation and detailed color interference analysis. This proposed device outperforms the other alternatives in terms of cost, sample volume, detection time, energy usage, weight, and other factors. In any resource-constrained scenario, this cheap, portable, and user-friendly 3D microfluidic device can be used to analyze liquid foods before consumption.

Title: High-performance miniaturized physical sensors based on nanocomposite materialsand nanostructures

Polymer-based composites have exhibited great potential in the field of miniaturized flexiblephysical sensors. However, developing flexible sensors having high sensitivity to stimuli, fastresponse time, low power consumption and multi-directional sensing simultaneously stillremains a challenge. Compatible fillers, when used in appropriate concentration can bringsignificant changes in sensor’s performance. Nonetheless, polymer-filler compatibility,uniform dispersion of fillers within the polymer matrix, and their alignment are certain factorsthat determines the sensor’s performance. Similarly, by changing the structural hierarchy ofthe sensing material the sensor response can be tuned. At FERN lab, we design and fabricatehigh performance and mechanically robust physical sensors based on novel nanocompositeswith applications in wearable sensors for health monitoring, energy-saving devices, and smartstructures. We investigate novel nanocomposite materials, strive to understand theirstructure- property relationships, optimize sensing properties using micro/nano-structures,and design and fabricate sensors having superior sensitivity, wider sensing range and smallerresponse times etc. Besides, we also seek for compatible fabrication techniques that can bringdown the cost of production and offers opportunities for mass production. Our currentprojects focus on developing flexible temperature and strain sensors from highly conductivenanocomposite fibres by wisely embedding both metallic and carbonaceous nanofillers inpolymer matrix to exploit their combined advantages without sacrificing their individual ones.Our research is interdisciplinary, combining advanced research fields from material science tomanufacturing and applied engineering and taking a multidimensional approach we aim todeliver solutions to develop high performance flexible sensors.

Keynote Speaker : Dr. Pranab K. Mondal, Mechanical Engineering Department at IIT Guwahati

Title: Low-cost POC devices for detection of Vitamin D-deficiency in blood

Increase in chronic diseases made researchers realize that not only Vitamin-D deficiency affects the bone health but it also aggravates cancer and cardiovascular diseases. Ongoing regulations suggest that 25-hydroxyvitamin D values <12 ng/mL (30 nM) are associated with an increased risk of rickets/osteomalacia, whereas in the healthy general population, 25-hydroxyvitamin D concentrations between 20 and 50 ng/mL (50 to 125 nM) appear to be safe and sufficient for skeletal health. Lateral flow assay plays an important role in analytical sciences due to some exceptional capabilities like sensitivity, specificity, low cost, compact size and user-friendly operation. The proposed prototype, as demonstrated below, is based on the principle of competitive immunoassay in which labelled antibodies after binding with analyte (here Vitamin D3) flows laterally towards the test line for competitive binding with the immobilized vitamin D3. Quantification is done based on the colorimetric signal difference between the test line and the control line. One of the clear benefits of this immunoassay is the ‘sample-in-answer-out’ system, in which the input is whole/minimally blood and the output is a qualitative or quantitative diagnosis of biomarkers of disease or bio-analyte of interest

Title: Short Peptide-based Nanostructures as Microswimmers for Potential Biosensor Applications

The nanomotor chassis constructed from biological precursors and powered by biocatalytictransformations can access intelligent properties.1-3 In this context, we developed cross-β amyloidbased nanomotors (amylobots) from short amyloidogenic peptide sequences.1-3 Importantly, motilesoft nano constructs were exploited to feature navigational ability through a synergistic action oftwo orthogonal bio-engines (enzymes), emulating the advanced traits of bacterial motility. Thedesign principle demonstrated the enhanced diffusivity of urease with increasing fuel concentration(urea) and chemotactic motility of cytochrome C towards the chemical cue (substrate). Further, thedual catalytic engines allowed the amylobots to be utilized for enhanced catalysis in organic solvent;a critical advantage for technological applications of the biocatalysts. In addition, utilizing a complexdivergent cascade, we further exploited the catalytic potential of cross-β amyloid nanotubes todevelop motile fluorescent microswimmers. The short peptide-based paracrystalline nanostructuresfeatured cascade-driven microscopic motility. Moreover, fluorescent microswimmers exploited theorthogonal properties through a divergent cascade network, thus foreshadowing the complexities ofextant biology and with the possibility of sensing analytes in complex mixtures.

Keynote Speaker: Dr. R. Vinu, Dept. of Chemical Engineering, IIT Madras

Title of Talk:  Hydrothermal Liquefaction of Diverse Feedstocks for Sustainable Solid Waste Management and Energy Production in the Indian Context


Hydrothermal liquefaction (HTL) is a promising thermochemical conversion technique to process wet feedstocks. The products of HTL include organic bio-crude, biochar, and non-condensable gases. Compared to other waste-to-energy conversion processes like combustion, gasification and pyrolysis, HTL is a promising route as it does not involve drying of the feedstock for moisture removal, which is usually a costly operation. Although HTL is a reasonably established process in the laboratory in litre-scale to process few milligrams to grams of biomass, it is yet to be employed on a commercial scale to process huge quantities of diverse feedstocks.

HTL is an important process in the Indian context for municipal solid waste (MSW) management. Indian MSW is unique as it is a heterogeneous, unsegregated mixture of bio-organic and bio-inorganic wastes. In this presentation, I will describe our journey in developing HTL technology to convert a variety of feedstocks including biomass residues, micro/macro algae and MSW to fuels and energy. Through a series of well-designed experiments, we have determined the optimum process conditions to maximize the product yields and their quality. I will also discuss our approach to scale-up this process to clean the existing landfills, and the go-to-market strategy.

Keynote Speaker: Dr. Amit Arora, Centre for Technology Alternatives for Rural Areas (CTARA), IIT Bombay

Title of Talk: Green biorefineries towards circular economy: In search of healthy alternatives


The processing waste generated from industries globally account for an average of 1.5 billion tonnes. India is the one of the largest producers of fruits and vegetables in the world with an annual production of around 250 million tonnes. The quantity of horticultural processing waste (HPW) coming from agro processing industries is quite significant.Fruits such as banana, mango, citrus, pomegranate, pineapple, etc. on processing generate waste which is as large as 30-50% of the fruit. The by-products from these industries have high moisturecontent and are thus prone to microbial spoilage. Most of the processing waste ends up going to dumping yards.  The growing need for 'natural products' and the presence of useful bioactive compounds in HPW, defines a converging scope for value addition of the waste.The HPW may serve as an alternative source for recovery of bioactive compounds(Pectin, peptides, carbohydrates, proteins, lipids, and polyphenols) which are highly valuable ingredients for food and pharma applications.

In our lab, myresearch group is focusing on developing processes to extract high value productsin close association with the principles governing the concept of Green Chemistry, which are mainly aimed to reduce wastes and to promote a more efficient use of energy and resources.  The growing need for 'natural products' and the presence of useful bioactive compounds in fruit processing waste defines a converging scope for value addition of the waste and generate high value products.  Also, converting a renewable non-fossil carbon to multiple value added products in an integrated biorefinery model would assure a continual energy and material supply. Over the longer term, opportunities for “bolting-on” such technology to existing biorefineries, or constructing new greenfield developments, would provide important revenue diversification.

Keynote Speaker: Dr. Papita Das, Department of Chemical Engineering and School of Advanced Studies in Industrial Pollution Control Engineering, Jadavpur University, Kolkata

Title of Talk: Circular economy on utilization of waste biomass in pollution control and energy generation


Agricultural biomass, specifically lignocellulosic biomass has the potential of contributing a lot to the global economy. Compared to fossil fuels biomass provides sustainable, greener and cleaner energy options. Lignocellulosic biomass has the potential to be used for the development of various value-added products. Lignocellulosic biomass can be broken down into sugars for their conversion into biofuels and bio products like alcohols, organic acids and hydrocarbons by the use of microorganisms, enzymes and catalysts. Lignocellulosic biomasses itself have their own unique properties. They are themselves natural polymers. Thus, various polymers and its composites could be synthesized from them. The cellulose when obtained from any lignocellulosic material can be converted into nano-cellulose. Moreover, from cellulose and hemicellulose phenol, furfural, succinic acid, levulinic acid can be obtained. Thus, these biomass utilization processes can be planned together, and diverse products and applications can be obtained from lignocellulosic biomasses forming a circular economy when applied industrially and these waste materials may also be used for reducing pollutants present in wastewater.

Title: Opportunities and Constraints in the Translation of Academic Research into a Product Development


Efforts are taken by the researchers throughout the world to develop different technologies for the better life style of the mankind. Most of the research problems addressed by the researches are narrowed research topic and depth to the concepts of Engineering and Technology. As an outcome of the PhD, most of the strategic solutions proposed by the researchers are novel in the state of art. However in the present research scenario, most of the academic researchers transpire the publications of research articles in the SCI journals or in the conferences. A product level development or a patent is materialized as an outcome of very few PhDs. A wide gap exists between the researchers and the power industries to translate the novel concepts or solutions proposed by the researchers as the part of their research in to a product. The major constraints which deviate the academic researchers from the product level development are: the present promotion policies of the academic institutions, criteria considered to award a PhD degree, limited exposures to formulate the industrial level research problems, lack of collaboration between industry and academic, lack of understanding between an academician and an industrialist, insufficient background of knowledge that are required to develop a product as whole, etc.

Keynote Speaker :Dr. Debangshu Dey, Associate Professor, Electrical Engineering Department, Jadavpur University, Kolkata

Title: Synergism of Signal Processing & Machine Learning tools for Condition Monitoring Applications of Electrical Equipment


The growth in economy and developmental index in India has increased the per capita energy requirement in the country. The government has also taken up firm programmes to extend grid power to the entire population. On the other hand, a large section of the power infrastructure in developed as well as developing countries has become old. Statistics show that the majority of large power transformers were installed in the 1960s and ‘70s. Significant numbers of equipment, particularly transformers, are nearing end of their designed life or have already exceeded it. To extend the life of existing infrastructure, most of the power utilities now-a-days give effort towards condition-based predictive testing and maintenance. Costs can be reduced, first of all, by a transition from time-based maintenance (TBM) to condition based maintenance (CBM), as well as reliability can be increased if the actual conditions of the expensive high voltage components within the electric power transmission systems are accurately known. It is pertinent to mention here that such costly equipment like power transformers cannot be replaced overnight, if required. Proper asset management strategy is required which requires advanced methods and systems to obtain reliable condition monitoring data of such critical equipment in the power infrastructure. In India, there exists a lack of indigenous research in this domain, which is evident from number of research publications and possession of intellectual property rights. Most of the equipment and diagnosis packages are based on any single methodology and are foreign proprietary, which are used in our country as a black box. But considering the present scenario of our country’s power infrastructure this is high time to develop indigenous tools for such CBM of various electrical equipment. Hence, the present topic will throw some light on the conducted research and developed systems to address this issue by synergizing data acquisition, advanced signal processing and machine learning tools. This topic has practical importance in Indian power scenario and also has large societal impact considering the economic benefits as well as the benefits in getting uninterrupted power supply derived from such condition monitoring which is in line with the present day need for resource-constrained translational technologies.

Title: Electrical Biosensors Operating in Complex Biological Fluids for Resource Limited Environment


A major opportunity offered by biosensors in the field of diagnostics is enabling technologies that can selectively detect species at ultra-low levels. Such systems are of paramount importance in early detection of cancer and discovery of new biomarkers for treatment of complex diseases since the existing commercial technologies seldom reach these detection limits. In this aspect, we have developed a suite of affordable technologies for detecting species at ultralow concentrations which can operate in resource constrained settings. These technologies are based on label free electrical detection mechanisms which mostly deploy field effect transistor (FET) mode of operation of graphene and zinc oxide nanorods. Conventionally, these sensors demonstrate improved mass transport and are highly sensitive owing to their intrinsic transconductance but their sub-micron feature sizes restrict the fabrication only in specialized clean room settings. Further, the intrinsic device noise and the lack of reliable fabrication deteriorates the signal to noise ratio and hence biomolecule detection and quantification at extremely low levels in physiological fluids become challenging. We have addressed some of these issues by increasing the device dimensions to few hundreds of microns and yet achieve appreciable sensitivity and selectivity by appropriately controlling the device surface roughness and adopting molecular imprinted polymer technology for antibody free biorecognition. These strategies coupled with ring-shaped coplanar gate electrodes surrounding the active sensing regions, localizing the capture of biomolecules on the latter help to overcome the Debye screening effect and enhance the signal to noise ratio.

Title: Functionalized Graphitic Carbon Nitride (g-C3N4) Nanosheets for Flexible and Wearable TriboelectricNanogenerators (TENG)


TriboelectricNanogenerators (TENG) have evolved as alternating power sources for supporting today’s internet of things (IoT) based gadgets. TENG operates under the combined phenomenon of triboelectrification and electrostatic induction and converts mechanical energy to electrical energy. In this context, functionalized graphitic carbon nitride (g-C3N4) nanosheets can be a promising active material for TENG application. Through functionalization of g-C3N4nanosheets, the improvement in triboelectric output can be achieved by modifying the parameters like surface roughness, dielectric constant etc. and may lead to the development of flexible and light weight TENG for generation of power from human biomechanical movements. Additionally, the integration of such nanogenerator with a suitable processor and wireless technology may lead to the self-powered sensors to track human motion from remote location. Consequently, the functionalized g-C3N4nanosheets may form the base of futuristic wearable and flexible power sources that can be compatible for integration to human body at low cost.

Title: Magnesium: A Potential Degradable Bio-metal for Orthopaedic Applications


Magnesium (Mg) has the potential to be used as temporary bone fracture fixation device material owing to its ability to degrade in a physiological environment. Along with degradability, it has a relatively low density and Young’s modulus, good castability, and good biocompatibility, which are essential for bone replacement. However, widespread application of Mg is limited due to their poor mechanical properties and susceptibility to high corrosion rate, particularly when exposed to chloride ions in the physiological environment. Therefore, it becomes essential to increase the mechanical properties and control the degradation of Mg alloys during initial implantation time. In this context, addition of specific alloying elements, which can significantly alter the yield strength and biological properties of Mg, are of great importance. However, corrosion burst during the early stages of fracture plate and screw implantation is the biggest concern among the orthopedic community. Therefore, control of initial corrosion for up to 2 months, post-implantation, can take the materials to commercial success. Surface treatment by employing coatings on the Mg alloy substrate is one of the simplest ways to avoid corrosion of Mg alloys as it has no adverse effect on its mechanical properties.
