Nanomaterials Recycling

Mahendra Rai is an internationally recognized scholar with extensive contributions to microbial biotechnology and nanobiotechnology research, particularly in the green synthesis of metal nanoparticles using fungi and their application as nano‑antimicrobials. His work is highly interdisciplinary, bridging microbiology, biotechnology, and nanoscience, and he is an active member of several scientific societies. He has received multiple national and international distinctions, including the Father T.A. Mathias Award from the All-India Association for Christian Higher Education and the Medini Award from the Government of India. Professor Rai has also held numerous visiting scientist and visiting professor positions across Europe, South America, and Asia, contributing to long‑standing research collaborations in countries such as Brazil, Argentina, Hungary, Switzerland, Italy, Germany, and the United States. His sustained academic impact is reflected in his inclusion among the global top 2% of scientists in nanoscience and nanotechnology, and recognition as one of India’s leading researchers in biology and biochemistry, including a Biology and Biochemistry India Leader Award from Research.com. Tuan Anh Nguyen is a Senior Principal Research Scientist at the Institute for Tropical Technology, Vietnam Academy of Science and Technology, Hanoi, Vietnam. He received a BS in physics from Hanoi University in 1992, a BS in economics from Hanoi National Economics University in 1997, and a PhD in chemistry from the Paris Diderot University, France, in 2003. He was a Visiting Scientist at Seoul National University, South Korea, in 2004, and the University of Wollongong, Australia, in 2005. He then worked as a Postdoctoral Research Associate and Research Scientist at Montana State University, United States in 2006-09. In 2012 he was appointed as the Head of the Microanalysis Department at the Institute for Tropical Technology. His research areas of interest include smart sensors, smart networks, smart hospitals, smart cities, complexiverse, and digital twins. He has edited more than 74 books for Elsevier, 12 books for CRC Press, 1 book for Springer, 1 book for RSC, and 2 books for IGI Global. He is the Editor-in-Chief of Kenkyu Journal of Nanotechnology & Nanoscience.
