Dr. Aftab Aslam Parwaz Khan is presently working as an Assistant Professor in the Center of Excellence for Advanced Materials Research, King Abdulaziz University, Jeddah, Kingdom of Saudi Arabia. He earned his Ph.D. in Chemistry from Aligarh Muslim University, Aligarh, India in 2011. He has authored 3 books, 15 chapters and more than 130 research papers published in journals of international repute. He is also an Editorial Board Member, as well as a reviewer of many reputed international journals. His research encompasses all aspects of nanomaterials, synthesis, and characterization as well as application in chemical sensing, biosensing environmental remediation of pollution, and drug delivery system for mechanistic and interaction studies using a wide range of spectroscopic techniques and thermodynamic parameters. Dr. Mohammed Nazim is working as a research scientist in the Division of Energy Technology, Daegu Gyeongbuk Institute of Science and Technology (DGIST), Daegu, Republic of Korea to produce clean energy materials. He is an experienced scientist with more than ten years research experience in clean energy technology applications via organic and hybrid solar cells. He has published more than 17 research articles of high quality, 6 chapters and 2 research patents with a high national and international exposure of research in scientific conferences and seminars. He simultaneously worked in various fields of chemistry, chemical engineering, and material science including nanomaterials, energy materials, green energy, and clean technologies. 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
