My research interests include synthesis, characterization, modifications, properties and assemblies of novel graphitic carbon nanomaterials (Graphene and its derivatives, carbon nanotubes with aligned arrays and doped arrays, hetero-atoms doped graphene/CNTs, carbon onions, carbon nano coils, carbon spheres, etc.), 2D analogous inorganic layered materials (MoS2, WS2, BN, MXenes, g-C3N4 etc.) and 3D-graphene-metal oxide/ graphene-CNTs hybrids, etc. for use in multi-functional applications, especially for energy (energy storage/ conversion), sensing, EMI shielding. Some more details are given below
