Vijay Kumar is an Assistant Professor at the National Institute of Technology Srinagar, Jammu and Kashmir, India. His current research endeavors include the synthesis, processing, and characterization of functional materials, solid-state luminescent materials, soft and ceramic materials, biopolymers, drug delivery devices, and wastewater treatment. During the last ten years of his research career, he has published more than 90 research papers in various reputed international journals. He has published one book and several book chapters in several excellent books. He is an expert in chemical lab work and characterization techniques for defects in metal oxides. He has admirable skill in the synthesis of materials in 0D, 1D, 2D and 3D forms with various shapes and sizes via different physical and chemical synthesis routes. He has in-depth knowledge in materials physics. His specialty is photoluminescence spectroscopy and its applicability towards display device application, LED fabrication, fingerprint detection, barcode detection, and security ink applications. Recently he is involved with the fabrication of flexible white light emitting diodes based on inorganic materials and development of Mini/ Micro- LEDs with the help of perovskite quantum dots. Dr. Vishal Sharma is presently working as an Assistant Professor at the Institute of Forensic Science & Criminology, Faculty of Science, Panjab University, Chandigarh, India. He currently heads the Institute at Panjab University. He has obtained his Ph.D. degree in Physics from Kurukshetra University, Kurukshetra, India and Inter University Accelerator Centre, New Delhi, India. He is the recipient of DAE Young Scientist Research Award in 2011. Recently he has been conferred the best researcher award by Panjab University under Promotion of University Research and Scientific Excellence (PURSE), DST Govt. of India grant and Dr. P.D. Sethi National Award in 2018. He is the author of more than 90 peer-reviewed scientific papers, six book chapters and three books as editor. His current research focus is in the field of Material Science and includes the synthesis of smart materials for different applications, nanophosphors, hydrogels, sensors (drug sensing, fingermark sensing). Hendrik C. Swart is a senior professor in the Department of Physics at the University of the Free State, South Africa. His research investigates the degradation of phosphors for field emission displays, as well as developing materials for nano solid-state lighting. He has been key in the development of processes to synthesize and deposit thin films of several types of semiconductor nanoparticles to enhance the color, luminescent intensity, and lifetime of such displays.
