Title: Probing Crucial Interfacial Dynamics of Nanohybrids for Emerging Biomedical Functionalities


Nanohybrids are composite of two individual counterparts, interacting at the molecular level exhibiting unprecedented properties than the constituents. The modified properties of the hybrid material have often dictated by the interfacial junction between the two moieties. Thus, it is crucial to understand the various critical interactions present at the interfacial position. The commonly used techniques for structural characterization as electron microscopy (SEM, TEM) or x-ray diffraction (XRD) can only be able to visualize the inorganic counterpart whereas the Fourier transformed infra-red spectroscopy (FTIR), Nuclear magnetic resonance (NMR) can distinguish the organic part predominantly. However, there exists necessity to probe the interfacial dynamical properties of the hybrids. There lie the advantages of ultrafast optical spectroscopic methods to envisage the interfacial properties. The junctional charge transfer or energy transfer processes which are the basis of unusual properties in nanohybrids can be rationalized using excited state lifetime measurements. Finally, the nanohybrids depict unprecedented biomedical applications in destruction of infectious diseases, liver diseases and cancer. The talk will be highlighted about various hybrid materials, their interfacial properties using ultrafast spectroscopy followed by enhanced biological activities.

Keynote Speaker 2: Prof. M.R.Ravi, IIT Delhi

Title: Biomass Gasification – Science, Technology and Applications


Conversion of biomass into clean energy is often achieved by first converting it into a clean gaseous uel and subsequently using it for applications that need a clean fuel, such as internal combustion engines. Biomass gasification is the thermochemical route to such conversion, and has been demonstrated to be a reliable and scalable technology for applications of small to medium sizes – a few kW to a couple of MW. The talk will dwell on the basic science of gasification, and discuss the translation of the science to working technology. In fact, this is another example where technology preceded science – just as in the case of many energy conversion technologies. The talk would throw light on technologies that exist commercially today for biomass gasification for various applications. Fixed bed gasification has been established as a robust technology, and downdraft gasification has been demonstrated to be reliable to generate engine-worthy clean producer gas, as early as during the times of World War II – and perfected in the past 3-4 decades. The talk would discuss design features of downdraft gasifiers, and some work done in simulating such gasifiers done by the author’s group would be presented. The talk would end with the outlook for such technologies to benefit climate concerns such as crop residue-burning in northern India and energy security for village industries.

Prof. M. R. Ravi is a Professor in the Department of Mechanical Engineering at IIT, Delhi, where he has been a faculty member since 1996. He obtained his Bachelors in Applied Science from University of Madras and Master of Engineeringand PhD from Indian Institute of Science, Bangalore. Prior to joining IIT Delhi, Prof Ravi held research positions at TU Delft and ChercheurAssocié, Laboratoire FAST, CNRS, Orsay, France and was a faculty member at IIT Bombay. His research areas include Heat Transfer, Computational Fluid Dynamics, Combustion, Biomass energy, Rural energy systems. He is currently involved in a number of projects which include Combustion characteristics of gaseous fuel mixtures, measurement of burning velocity of such mixtures, to investigate the effect of composition and equivalence ratio on burning velocity and stability regimes of flame. Computational simulation of open flames of such mixtures to study the effects of stretch field and preferential diffusion effects on the stability regimes; development and investigation of Biomass Gasification and Combustion systems, with specific interest in small scale (<=20 kW) systems for thermal and electrical applications, and powdery biomass based systems;   Energy Audit of rural industrial systems such as pottery kilns, soap stoves, smithy kilns etc. with an objective of fuel savings in such systems by applying basic principles of heat transfer and combustion.  and development of energy-efficient alternatives for such systems.


Keynote Speaker 3: Dr. Mahati Chittem, IIT Hyderabad

Title: Understanding difficulties in performing medical procedures in the hospital setting: A qualitative study


Background: The standard technique for peripheral intra-venous (IV) access (i.e., vein insertion) often results in many cases of difficult trials and multiple needle penetrations, thereby making the process very painful and risky. Consequently, this project at large, is developing a 3D vein viewer to help reduce these difficulties.

Objectives: The behavioural arm of this project aims to explore and determine the reasons for and experiences of difficulties in performing peripheral IV intra-venous from the perspectives of healthcare providers (i.e., physicians, nurses and technicians).

Methods: Practicing doctors’ (n=25), practicing nurses’ (n=25), practicing technicians’ (n=25) were recruited from various hospitals in Hyderabad. Conventional content analysis was used to analyze the data.

Result: Themes includes: (1) difficulties in performing peripheral vein intrusion: reasons for and experiences of performing the IV insertion, (2) managing difficulties: approaches to handle difficulties and ways by which they can be avoided/reduced, (3) role of communication in handling the procedural difficulties and (4) attitudes towards novel technology for vein viewing/IV insertion devices. The Cohen’s Kappa scores was calculated for all themes and there was more than 75% agreement between the coders.

Conclusion: The study findings reveal that healthcare professionals believe that the standard procedure of peripheral vein intrusion was difficult with major issues focused on viewing and accessing veins. A preference for more advanced device that offers better visibility, quick access and makes the process less painful and affordable was strongly suggested.

Keynote Speaker 4: Mr. Rashid, K., Co-Founder & Director at Genrobotic Innovations

Title: Empowering Society Through Technology


Manual scavenging is the world's worst job and one manual scavenger dies every 5 days in India despite the prohibition of Manual Scavenging by the Hon'ble Supreme Court's MS Act 2013 and over 4 million people engaged in manual scavenging as their livelihood in India. The manholes could kill a man within a short time during the cleaning process by releasing the poisonous gases which are trapped inside the sewage waste. Apart from the social atrocities, they are also exposed to different health problems by virtue of their occupation.

This problem can be only solved by technology and thus Genrobotics developed Bandicoot – The world’s first robotic scavenger capable of identifying the blockages inside the manholes and clearing them at a high speed of operation when compared with manual cleaning. The Human comparable innovation works with human-level flexibility inside the manhole which has the potential to change the lives of millions of manual scavengers. The advanced version Bandicoot V2.0 has poisonous gas sensing, automatic sewer line detection, 4 machine vision, wide-angle IR Light sensor cameras, IP 68 machine, smart UI system with self-learning algorithm, and tutorial videos in the local language for the workers to operate the Robot much easier.
