Welcome to The Chakma Research Group at Indian Institute of Science Education and Research Bhopal (IISER Bhopal). The group is a multi-disciplinary group and works on fundamental aspects of ultrasonics and sonochemistry focusing on the understanding of physical and chemical effects of ultrasound and cavitation. The group is also involved in identifying the synergistic effects of ultrasound-based hybrid processes to enhance the yield of the processes. Presently, the group particularly focuses on the synthesis of nanomaterials and their industrial applications such as desulfurization of liquid fuels, mineralization of toxic pollutants discharged from industries such as petroleum, pharmaceutical, and textile industries. The group also works on biodegradation of recalcitrant pollutants and biofuels synthesis through sonochemical route.
