Sasadhar Majhi received B.Sc. (Honours) degree in Chemistry and M.Sc. (Organic specialization), both from Visva-Bharati (a Central University founded by Rabindranath Tagore, a Nobel laureate). He received M.Phil (Chemistry) in 2009 and obtained a PhD from Visva-Bharati University under the supervision of Prof. Goutam Brahmachari. Currently, he serves as the coordinator of the department of chemistry (UG & PG departments) of Triveni Devi Bhalotia College (Government Sponsored and Affiliated to the Kazi Nazrul University, Asansol, previously affiliated to the Burdwan University), Raniganj, West Bengal, India. He started his professional career as an Assistant Professor of this college and worked as Assistant Lecturer at Patha-Bhavana, Visva-Bharati University (a Central University), Santiniketan, West Bengal. He is a member of IQAC and the Coordinator of the environmental science of TDB College. He teaches undergraduate and postgraduate students of chemistry and also undergraduate students of biochemistry. With over ten years of teaching experience, Dr Majhi has published several research papers in national and international journals of high reputate. Dr Majhi is co-editor of Science and Technology: A Concise History and Evolution. He has also participated in various national and international conferences and symposia. His research interests focus on the isolation and structural determination of natural products, semisynthetic products, total synthesis, green chemistry, as well as biological activities of phytochemicals. Prof. Sivakumar Manickam (Siva) is a chemical engineer with over 25 years of experience in nanomaterials, nanopharmaceuticals, and process engineering. Currently at the University of Technology Brunei, he previously worked at the University of Nottingham Malaysia, serving in leadership roles including Director of Research and founding director of the Centre for Nanotechnology. His research focuses on cavitation reactors, natural product extraction, water treatment, pharmaceutical nanoemulsions, and biosensors. He has authored over 250 papers, supervised 50+ students, and received numerous awards. He is also an executive editor of Ultrason Sonochem.
