Area of Interest

        Electrochemical (EC) Sensors- The focus of the research is to develop materials for sensing pollutants/biomolecules using the electrochemical method.  The environment of focus in our research is water or bodily fluids. The drinking or clean water sources are fast becoming scarce due to industrial and domestic pollution. An overview of analytical chemistry development demonstrates that EC sensors represent the most rapidly growing class of chemical sensors due to their advantage of portability and simplicity. Compared to the optical, mass, and thermal sensors, EC sensors are especially attractive because of their remarkable detectability, experimental simplicity, portability, and low cost.

. Lithium-ion batteries (LIBs) have the highest energy density among all the secondary battery systems. Nevertheless, current LIB technology is not sufficient to meet the requirements for high performance/large-scale energy storage and electric vehicles applications and future energy demands and hence there is a demand for better electrode materials of higher capacity to meet the future requirements.

 

                 In the evolution of these technologies, material science has a vital role to play. In our work, we use the chemistry and the advantage of nanomaterials to build better materials for the above-mentioned applications to improve efficiency and performance. Given below are the outcomes as publications/patents of the work.
