Dr. Jaiswal-Nagar is an Assistant Professor at the School of Physics, Indian Institute of Science Education and Research Thiruvananthapuram (IISER-TVM), India. Her area of interest is very wide ranging from superconductivity, quantum criticality, charge transport at nanoscale to hydrogen storage and nanomaterials synthesis for gas sensing and chemical detection. Dr. Jaiswal-Nagar has contributed to the scientific community by publishing many peer-reviewed research articles in the above-mentioned areas. Dr. Dixit is a Postdoctoral fellow at the School of Physics, Indian Institute of Science Education and Research Thiruvananthapuram (IISER-TVM), India. Her area of interest is focused on hydrogen storage. She has studied many materials such as metal hydrides, nanomaterials, and alloys for hydrogen storage application. She has also worked on bio-waste materials for water filtration. Currently, she is focused on studying the hydrogen sensing behavior of hybrid nanomaterials using the green chemistry synthesis route. Dr. Devasahayam is a senior research fellow at the Department of Chemical Engineering, Monash University, Australia, currently focusing on carbon dioxide reduction through advanced energy conversion and utilization technologies and energy and emission reductions towards sustainable processing of materials. She has already edited Sustainability in Mineral and Energy Sectors, CRC Press 2017. She has authored many peer-reviewed papers in related areas.
