Dr. Aneeya Kumar Samantara is presently working as a post-doctoral fellow at School of Chemical Sciences, National Institute of Science Education and Research, Khordha, Odisha, India. He has pursued his PhD. at CSIR-Institute of Minerals and Materials Technology, Bhubaneswar, Odisha, India. Before joining the PhD. program, he completed the Master of philosophy (M.Phil.) in chemistry from Utkal University and Master in Science in Advanced Organic Chemistry at Ravenshaw University, Cuttack, Odisha. Aneeya’s research interests include the synthesis of metal oxide/chalcogenides and graphene composites for energy storage and conversion applications. To his credit, he has authored or co-authored 21 (twenty one) peer-reviewed international journal articles, six books (two books for Springer, two for Arcler Press and two in Global Publishing house, India) and four book chapters. Four books and two research journals are in press and are expected to publish soon.Dr. Satyajit Ratha has pursued his PhD at the School of Basic Sciences, Indian Institute of Technology, Bhubaneswar, India. Prior to joining IIT Bhubaneswar, he received his Bachelor of Science, First Class Honours from Utkal University, in 2008 and Master of Science from Ravenshaw University in 2010. Satyajit’s research interests include two dimensional semiconductors, nanostructure synthesis, applications, energy storage devices and supercapacitors. He has authored or co-authored about 20 articles in peer-reviewed, international journals, two books for Springer and two for Arcler Press.
