RESEARCH INTERESTS o Solidification of concentrated alloys The phase formation under non-equilibrium condition in concentrated alloys is field that remains to be explored. Our research activity deals with understanding the phase selection and morphological evolution using the process of laser resolidification. o Nanostructured materials The research focuses on phase transformation of binary and ternary alloy nanoparticles embedded in crystalline, quasicrystalline and amorphous matrices. Understanding the melting and solidification of alloy nanoparticles is a challenge. We are also working in the area of multicomponent nanoeutectic alloys. o Energy materials (new area) Hydrogen is seen by many as the energy carrier of the future and science and technology to produce, store and utilize hydrogen has emerged as an international research priority. We work on new catalytic materials for production and storage of hydrogen energy. o Size effect of ionic nanoparticles (new area) The research on ionic nanoparticles is new and expanding very fast. The ionic particles are characterized by strong Coulomb interactions between the positive and negative ions. At nanosize, the these Coulmbic interactions get modified leading to change in behavior of the ionic particles. We use top-down approach to prepare the ionic nanoparticle to see anomalous lattice expansion, insulating behavior at nanoscale o Electron microscopy of materials Transmission and scanning electron microscopic tools are utilized to study the phase selection and morphological evolution alloy phase, phase transformation of nanocrystalline as well as amorphous alloys. o Phase transformation Phase transformations of metallic and ceramic materials o Geopolymer (new area) Preparation of geopolymeric cements from fly ash and assessment of compressive behaviour
