Development of Porous and Ultra-Low density materials 

Materials with low density and high strength are demand for energy efficient and high speed automotive, aerospace, electronic and biomedical etc. applications. Utilizing energy efficient bottom-up synthesis approach, we explore different methods to interconnect nanomaterials such as carbon nanotube, graphene, silicon carbide, ceramic/metal nanoparticles and boron nitride etc. Such approach results in highly porous materials with ultra-density (lower than 1g/cc) with a reasonable strength.

Metal-intermetallic based high-temperature in-situ composite                                                 

The high-temperature strength of Eutectic alloys attracted the attention of metallurgist community. Such class of alloys can have high strength as compared to conventional alloys, but room temperature ductility is posses a big challenge. The ternary alloy system provides addition degree of freedom to tune the composition and hence microstructure, which can enhance the plasticity. In the current project, our team is looking to develop Al, Cu, Ti, Ni, Nb and Co-based alloys with eutectic microstructure.

Materials Science and engineering for society                                                                  

Under this theme, we would like to explore the possibility of usages of our materials understanding to solve the problem for society/humanity. We have been working on beneficiation of e-waste using environmental friending techniques, porous materials for CO2 absorption and conversion of waste materials into useful energy source etc.
