Akil Ahmad is a Research Fellow at University of KwaZulu Natal, South Africa as Postdoctoral Fellow. He was previously Visiting Researcher of Chemical Engineering, Centre of Lipid Engineering and Applied Research, University Technology Malaysia (UTM), Malaysia. His research interest in the areas of environmental pollutants and their safe removal, synthesis of nanoparticles and Nano-sorbents (GO, CNT), photo-degradation and antimicrobial effects, preparation of various Chelating sorbents/adsorbent to prevent the environment, water and wastewater treatment, adsorption and ion-exchange, instrumental methods of analysis, thermodynamic and kinetic studies, and preconcentration and method validation with standard reference materials. Rajeev Kumar received a M.Sc. in Analytical Chemistry (2006), and M. Phil (2008) and Ph.D. degree in Applied Chemistry (2011) from Aligarh Muslim University, India. He is currently working as associate professor at the Environmental Science Department, King Abdulaziz University, Jeddah, Saudi Arabia. His research activities are in the areas of wastewater treatment and material science. Rajeev studies the adsorption and photocatalytic properties of the nanomaterials for the removal of contaminants from wastewater. He has published more than 50 research articles and chapters in the journals such as the Chemical Engineering Journal, Journal of Colloid and Interface Science, RSC Advances, Journal of Environmental Sciences, Journal of environmental management, Journal of Industrial and Engineering Chemistry, Desalination etc. Dr. Mohammad Jawaid is currently affiliated with the Department of Chemical and Petroleum Engineering at United Arab Emirates University. Previously he was a senior fellow (professor) in the Laboratory of Biocomposites Technology at the Institute of Tropical Forestry and Forest Products (INTROP), Universiti Putra Malaysia. He is an eminent scientist with more than twenty years of teaching, and research experience in composite materials. His research interests include hybrid reinforced/filled polymer composites, and advanced materials such as graphene/ nanoclay/fire retardant, lignocellulosic reinforced/filled polymer composites, and the modification and treatment of lignocellulosic fibres and solid wood, and nanocomposites and nanocellulose fibres.
