Dr. Kokkarachedu Varaprasad is working as an Associate Professor in the Facultad de Ingeniería, Arquitectura y Diseño, Universidad San Sebastián, Lientur 1457, Concepción, Chile. He received PhD (2011) in biocidal temperature-sensitive hydrogels from the Department of Polymer Science and Technology, Inda. He worked as an Investigator at the Advanced Polymer Research Center (CIPA). He received 3 International Postdoctoral Fellowships at Creighton University USA, Tshwane University of Technology SA, and Universidad de Concepción, Chile. He developed the bioactivity of hybrid nanomaterials for advanced biomedical applications. He has published over 128 articles, including 2 patents, 2 books, and 30 book chapters, has 40 h-index and more than 6500 citations, and is the recipient of 10 research grants (2 projects ranked as 1st and 4th, respectively. He edited special issues for Journals and was a member of several societies. He guided several students in the nano-bio-materials field. His name has been listed in the Top 2% of scientists in the world under biomaterials, nanoscience, and nanotechnology in a recent survey conducted by Stanford University to recognize (2021). His primary objective is to translate primary nano and polymer technology research results for the next generation of biomedical applications. Prof. Rotimi Sadiku is currently an Emeritus Professor at the Tshwane University of Technology, Pretoria, South Africa.Academic or Professional Affiliation: Institute of Nano Engineering Research (INER), Department of Chemical, Metallurgical and Materials Engineering (Polymer Technology Division), Tshwane University of Technology, Pretoria, South Africa.Professor Emmanuel Rotimi Sadiku started his career as early as in 1976 as assistant Supervisor at the Zaria Industries Limited Nigeria and later received the Nigeria Government Scholarship to pursue a BSc [Hons.] (1980) degree at the University of Strathclyde, Glasgow, Scotland, UK. During this journey, he received numerous awards as best student and then, received the Nigeria government scholarship to pursue his PHD (1986) in Polymer Science at University of Strathclyde. He did a 1½ years postdoctoral fellowship at the CNR/University of Genova, Italy (1989/90) After receiving postdoctoral fellowship award (Swedish Institute Research Fellowship) he joined (1990) the Department of Polymer Technology, Royal Institute of Technology, Stockholm, Sweden. He did spend ½ year at the Faculty of Physics, Freiburg University as Visiting Scientist. In 1999, he later received South African Research Foundation (NRF) Fellowship award to join University of Stellenbosch, Institute for Polymer Science. He has published more than 400 research articles, 110 book-chapters and he currently, has a Google Scholar h-index of 50 with a current citation of 11000. Professor Sadiku has 10 South AfricanPatents and 1 patent in India (registered or under registration). He has supervised many Doctoral and Masters’ students’ and has mentored many Postdoctoral Fellows. He specializes in polymer physics, especially X-ray diffraction, light and electron microscopy, rheology, and viscoelasticity of polymers.
