Electrochemical water splitting technique is an alternative method to produce renewable energy which shifts the dependence on hydrocarbon based energy resources to a new avenue. For overall water splitting, efficient catalyst is required for both OER and HER, using low-cost and stable electrode materials. In recent developments to spin specific water splitting, it has been observed that OER can be controlled by spin manipulation at the electrode-electrolyte interface by coating/decorating a chiral molecule on the surface of the electrodes. We demonstrate the effect of chiral structure on the spin manipulation at electrode's surface and study the catalytic behaviour of the organic chiral molecule coated electrodes for both OER and HER.

Spin filtering by chiral molecules with inversion asymmetry results in a remarkable spontaneous yield of spin-polarized electrons. The chiral-induced spin selectivity, describing the aforementioned effect, has been accomplished by taking structurally different biomolecules such as DNA , proteins and peptides , etc. The ubiquitous influence of the CISS effect in different areas of applications includes chiral molecule sensing, enhanced oxygen evolution reaction (OER) ,DNA damage detection, etc. We have built a label-free DNA hybridization sensor based on the CISS effect and used it to detect the Dengue virus. Our research has shown encouraging outcomes, and it can be used in the development of commercial spin-specific DNA hybridization sensors.   

Among energy storage devices, supercapacitors are gaining huge attention owing to their unique features. These include high power/energy density, fast charging–discharging ability, and long cycling life; meanwhile require low maintenance cost . Therefore, supercapacitors are very attractive as the energy source for portable electronic gadgets, memory backup systems and hybrid vehicles. Nevertheless, efficiencies of supercapacitors are highly dependent and affected by the electrochemical properties of the electrode materials employed therein. We examine various properties of different nanocomposites to be utilized in supercapacitors. Moreover we also study the role of magnetic field in enhancing the properties of the composites.
