Dr. Mohammad Mansoob Khan is a Professor (Senior Assistant) at Chemical Sciences, Faculty of Science, Universiti Brunei Darussalam. He earned his PhD from Aligarh Muslim University, India in 2002. Afterwards he has worked as researcher, lecturer and Professor at different universities in India, Ethiopia, Oman, and South Korea. Since 2015 he is working as a Professor (Senior Assistant) at Universiti Brunei Darussalam. His main research interests are in the field of nanosciences, nanotechnology and nanomaterials, especially green syntheses of metal nanoparticles, inorganic nanohybrid and nanocomposite materials for Energy and Environment applications such as catalysis, photocatalysis, optoelectronic devices, hydrogen production and sensing.Dr. Debabrata Pradhan has a position as Associate Professor at the Materials Science Center of the Indian Institute of Technology, Kharagpur. He received a PhD in Chemistry from the Indian Institute of Technology in Mumbai in 2003. After postdoctoral research in Taiwan (Tamkang University) and Canada (Univ. of Waterloo) he joined the Indian Institute of Technology in Kharagpur in 2010, first as Assistant Professor, and since 2015 as Associate Professor. His research interests are in nanotechnology, especially the synthesis, characterization, and applications of nanomaterials including metallic and semiconducting nanostructures and their structure-property correlations.Dr. Youngku Sohn is an Associate Professor in the Department of Chemistry at Chungnam National University in South Korea. He received his PhD from the University of British Columbia in Canada in 2004. Afterwards he spent some time as postdoctoral researcher at the same university, before moving to the University of Texas in Austin (USA) in 2005 and then to the University of Waterloo, Canada in 2007. From 2008 to 2017 he held a faculty position at Yeungam University. Since 2017 he has a position as Associate Professor atChungnam National University with broad research interests in Physical Chemistry, Spectroscopy, Surface Chemistry, Catalysis, Energy and Environments.
