Fabian I. Ezema is a Professor at the University of Nigeria, Nsukka. He obtained a PhD and MSc in Physics and Astronomy from the University of Nigeria, Nsukka, and a BSc from the then Anambra State University of Science and Technology, Enugu. His researches are on several areas of Materials Science: synthesis and characterizations of particles and thin films materials through chemical routes with emphasis on energy applications. He is interested in materials for thin film solar cells fabrication and nanoparticle synthesis. For the last 15 years, he has been working on the nano/submicron-sized materials for energy conversion and storage (cathodes, anodes, supercapacitors, thin film solar cells, DSSC, etc.), including novel methods of synthesis, characterization, and evaluation of the electrochemical and optical properties. He was a CV Raman Fellow at the Shivaji University, Kolhapur, India, in 2011 and MIF Fellow at Tokyo University of Science, Japan, in 2013. He is avisiting professor to NRSEMT (MATECSS UNESCO Chair) in Varennes, Quebec, Canada, and iThemba Labs, South Africa. He is also a Fellow of UNESCO-UNISA South Africa Chair in Nanosciences and Nanotechnology (U2ACN2). He was awarded the University of South Africa (UNISA) visiting researcher program (VRP). Fabian is a senate representative to National Center for Energy Research and Development (NCERD), University of Nigeria, and due to his commitment to research and international visibility was appointed Pioneer Acting Director, International Office of the University of Nigeria after the approval of the office by the University Senate. He has served as Coordinator, Natural Science Unit, School of General Studies, UNN. He is the Coordinator of Nano Research Group, University of Nigeria, Nsukka. He is the pioneer Dean, Faculty of Natural and Applied Sciences, Coal City University Enugu, Nigeria. Fabian has published over 180 high-impact papers in various national and international journals and gave over 50 talks at various conferences, workshops, and seminars. His h-index is 37, i10 index of 141 with over 4800 citations as in google scholar.Chandrakant D. Lokhande is presently working as a Dean and Research Director at D Y Patil Education Society (Deemed to be University), Kolhapur, India. He has been working on several areas of thin film technology, ranging from chemical synthesis of thin films to their applications in solar cells, gas sensors, and supercapacitors. Moreover, he made a great contribution to designing several prototype devices such as supercapacitors and heterojunction-based room temperature gas sensors. He received his Ph.D. from Shivaji University, Kolhapur, in 1984, without viva voce examination as his thesis was adjudged as “Excellent.” Later, in 1987, he joined as an assistant professor in Physics and became professor and Head at Shivaji University, Kolhapur, immediately after accomplishing his first postdoctoral stay atthe Weizmann Institute of Science, Israel. He has won many awards and received many honors. He was appointed as Fellow of the Institute of Physics, London, in 1990; was visiting scientist in the Indo-Polish CEP scheme in 1991; was INSA Visiting Fellow in 1993; is the first recipient from Shivaji University of the prestigious Alexander von Humboldt Fellowship, Germany, in 1996 and Brain Pool fellowship of South Korea in 2003; was participant in Noble Laureates Meeting, Lindau, Germany, in 2001; was visiting professor at Hanyang University, South Korea, in 2006; was awarded a Rajya Shishak Purshakar, Government of Maharashtra State in 2009, and Best Teacher Award from Shivaji University in 2010. He is presently an editorial board member of Electrochemical Energy Technology, De Gruyter; the fellow, Maharashtra Academy of Sciences from 2012; an expert member, and a distinguished visiting professor in polymer chemistry, Institute of Chemical Technology, Mumbai, from 2012. He is the author of more than 650 papers in international journals with “h” index 97 and more than 35,200 citations, edited 11 books, fled more than 50 patents, and directed more than 65 PhD theses. Recently, he has been listed at first position in top 2% scientists in the subject of Applied Physics in India by a Stanford University SurveyAbhishek Lokhande is currently working as a Researcher at the Khalifa University of Science and Technology, Abu Dhabi, United Arab Emirates (UAE). He obtained his Ph.D. degree in 2019 in Materials Science and Engineering from Chonnam National University, South Korea. Before that, he obtained his Bachelor's (2012) and Master's degree (2014) in Mechanical Engineering from Shivaji University, India. His research interests include the synthesis, characterization, and development of novel efficient metal chalcogenide nanomaterials/thin films for thin film solar cells, gas sensors, and energy storage/energy conversion systems. He has published over 100 research papers and his h-index is 34, i10 index of 85 with4000 citations as in google scholar.
