V. K. Jain completed his Ph.D. in Solid State Physics from IIT Delhi in 1970. He joined Solid State Physics Laboratory in 1972 and worked as Director Grade Scientist until 2003. He was Head of the silicon devices and Micro Electro Mechanical Systems (MEMS) division and developed many new technologies. His research on electro-luminescence in porous silicon was the first international observation and was reported by Photonics Spectra, USA, and Electronics Asia. He has also developed the technology for space quality silicon solar cells. He is among those who have started the MEMS program in the country and also produced many devices. He was also associated with the National Programme on Smart Materials and MEMS technology from the beginning. He has published more than 200 papers in national and international journals, edited a few books, and has filed more than 50 patents (including 12 granted). His research interests include solar energy, thermal heat storage system, sensors, biosensors, water purification, etc. He has started two new institutes at Amity University—Amity Institute for Advanced Research and Studies (Materials and Devices) and Amity Institute of Renewable and Alternative—and working as Distinguished Scientist and Professor. Chandima Gomes is a Full Professor of High Voltage Engineering at the University of Witwatersrand, South Africa. He has about 25 years of teaching experience. His specialization areas include high-voltage engineering, lightning and thunderstorm physics, energies, environmental sciences, and electromagnetics. He has 18 research and 10 program grants, 128 journal publications, 17 chapters, and 200 conference proceedings papers to his credit. He is Senior Adviser to the National Lightning Safety Institution, USA, and was Chief Adviser to African Centers for Lightning and Electromagnetics based in Uganda. Being an engineering consultant for several companies in Asia and Africa, he has over 20 years of international experience in designing lightning protection systems and providing solutions for electromagnetic issues. Abhishek Verma did his Ph.D. in Electronic Science from Delhi University in 2009. He further joined the National University of Singapore, Singapore, as a postdoc in solar cells technologies. Presently, he is working as Associate Professor at Amity University, Noida. His areas of interest are organic and inorganic 3rd-generation solar cells, solar thermal nano-enhanced phase change materials, nanotechnology, Agrivoltaics, clean energy generation, quantum dots, CNT, Graphene, Si NWs, optical (UV and IR) sensors, volatile/toxic gas sensors, LPG sensors, Si nanowire technology-based sensors and devices. He has organized the many prestigious International Conferences, as Secretary. He has filed over 20 patents (2 granted), published 5 books as an editor and published over 60 papers in refereed international journals and conferences.
