Current Research Activities
1. Energy harvesting materials: Our primary research is to design and fabricate mechanical energy harvesting materials and their applications. We validate our concept of designing piezoelectric/triboelectric nanogenerator using these materials that can be used to easily harvest mechanical energy form the everyday life such as, body movements (finger imparting, walking, neck up and down, swallowing, etc), heartbeat, blood flowing, sea waves, and air blowing. Currently, we are also working on bio based materials for in-vivo/in-vitro application. The contribution of these research works has been published in Advanced Energy Materials, Industrial & Engineering Chemistry Research, Nanoscale, and RSC Advances.
2. Energy storage materials: We synthesize several new and efficient cost-effective electroactive materials for supercapacitor electrodes applications. We usually assemble two similar or different types of electrodes to fabricate high-performance supercapacitor device. The designed supercapacitor can be used as handy and safe energy storage device for modern electronic industries with a very high power, energy density and stability. Currently, we are also working on self-charging supercapacitor device. The contribution of these research works has been published in various reputed journals, like, ACS Applied Materials & Interfaces, Journal of Applied Electrochemistry, Industrial & Engineering Chemistry Research and Electrochimica Acta.
3. Polymer based electromagnetic interference (EMI) shielding materials: We are working to develop conductive nanofiller based polymer composites with low cost, flexible, light weight, strong corrosion resistance, and broad absorption bandwidth properties for EMI shielding materials. Restriction of both incoming and outgoing electrical and magnetic fields, i.e. high microwave absorption property by polymer composite is the main goal of our research work which are applicable in the area of aircraft, aerospace, automobiles, and fast-growing next-generation electronics. The outcome of our research works were published in the journals like, Carbon, ACS Applied Materials and Interfaces, RSC Advances, and Express Polymer Letters.
