Dr. Onoyivwe Monday Ama received his Ph.D. in Chemistry from the University of Johannesburg, South Africa in 2017. His research activities encompass the areas of electrochemistry, water science, materials science, and nanotechnology, with a focus on the applicability of exfoliated graphite nanocomposites in electrochemical technology. He has published a number of peer-reviewed papers in journals such as the Journal of Electroanalytical Chemistry, Electrocatalysis and the International Journal of Eletrochemical Science. Professor Suprakas Sinha Ray received his PhD in Physical Chemistry from the University of Calcutta in 2001, and is currently a chief researcher on polymer nanocomposites at the Council for Scientific and Industrial Research (CSIR), Pretoria, South Africa, and manager of the Centre for Nanostructures and Advanced Materials, DSI-CSIR Nanotechnology Innovation Centre. Prof. Ray’s current research focuses on polymer-based advanced nanostructured materialsand their applications. He is one of the most active and highly cited authors in the field of polymer nanocomposite materials and was recently rated by Thomson Reuters as one of the world’s most impactful and influential scientists and among the top 50 high-impact chemists (out of 2 million chemists worldwide). He has co-authored 3 edited books and authored 4 books and 30 book chapters on various aspects of polymer-based nano-structured materials & their applications; he has also co-authored or authored 350 articles in high-impact international journals and 30 articles in national and international conference proceedings. He holds 6 patents, and he and his research team have commercially developed 19 different products. His honors and awards include the prestigious 2016 South Africa National Science and Technology Award (NSTF), the 2014 CSIR-wide Leadership Award, the 2014 CSIR Human Capital Development Award, the 2013 Morand Lambla Award (top award in the field of polymer processing worldwide), and an award from the International Polymer Processing Society, USA. He also serves as an Extraordinary Professor at the University of Pretoria and as a Distinguished Visiting Professor at the University of Johannesburg.
