Research Interests

Nanomaterials, superconductors. dielectric oxides and intermetallics . Our group has contributed extensively to the field of dielectric and superconducting oxides and polar intermetallics. Our current interests are mainly in the synthesis and properties of 1) microemulsions to design nanomaterials with controlled shape and size 2) anisotropic nanostructures, core-shell nanoparticles and nanocomposites) 3) applications of nanostructures to photocatalysis, hydrogen evolution and water purification and 4) oxypnictide superconductors of the type, Ln(O/F)FeAs. We have been involved in several important Nanotechnology and materials related projects which include setting up of advanced techniques like, X-ray diffraction, light scattering and microscopy facilities AFM/STM/HRTEM/FESEM). We have organised four meetings on Nanostructured materials and nanotechnology (in 2003, 2006, 2007 and 2011) and two on advanced materials (2008 and 2011).
