Prof. Abdullah M. Asiri is the Head of the Chemistry Department at King Abdulaziz University since October 2009 and he is the founder and the Director of the Center of Excellence for Advanced Materials Research (CEAMR) since 2010 till date. He is the Professor of Organic Photochemistry. His research interest covers color chemistry, synthesis of novel photochromic and thermochromic systems, synthesis of novel coloring matters and dyeing of textiles, materials chemistry, nanochemistry and nanotechnology, polymers and plastics. A major achievement of Prof. Asiri is the discovery of tribochromic compounds, a class of compounds which change from slightly or colorless to deep colored when subjected to small pressure or when grind. This discovery was introduced to the scientific community as a new terminology published by IUPAC in 2000. This discovery was awarded a patent from European Patent office and from UK patent. He is also a member of the Editorial Board of various journals of international repute. He is the Vice- President of Saudi Chemical Society (Western Province Branch). He holds four USA patents, more than 800 Publications in international journals, seven book chapters, and ten books Dr. Inamuddin, is an Assistant professor at Department of Applied Chemistry, Zakir Husain College of Engineering and Technology, Faculty of Engineering and Technology, Aligarh Muslim University, Aligarh, India. He has extensive research experience in multidisciplinary fields of analytical chemistry, materials chemistry, electrochemistry, renewable energy and environmental science. He has worked on different research projects funded by various government agencies and universities and is the recipient of awards, including the Fast-Track Young Scientist Award and young researcher of the year award-2020 of the university. His current research interests include ion exchange materials, a sensor for heavy metal ions, biofuel cells, supercapacitors and bending actuators. Ali Mohammad is Emeritus Professor of Chemistry in the Department of Applied Chemistry, Faculty of Engineering and Technology, Aligarh Muslim University, Aligarh, India. His scientific interests include physico-analytical aspects of solid-state reactions, micellar thin layer chromatography, surfactants analysis, and green chromatography. He is the author or coauthor of 250 scientific publications including research articles, reviews, and book chapters. He has also served as editor of Journal, Chemical and Environmental Research being published from India since 1992 and as the Associate Editor for Analytical Chemistry section of the Journal of Indian Chemical Society. He has been the member of editorial boards of Acta Chromatographica, Acta Universitatis Cibiniensis Seria F. Chemia, Air Pollution, and Annals of Agrarian Science. He has attended as well as chaired sessions in various international and nation conferences. Dr. Mohammad obtained his M.Phil. (1975), Ph.D. (1978), and D.Sc. (1996) degrees from Aligarh Muslim University, Aligarh, India. He has supervised 53 students for Ph.D./M.Phil. and M.Tech. degrees.
