Title: Sol-gel synthesis of glasses and structural characterization through High resolution Solid state NMR.

Abstract of Research Project

The sol-gel process has proven immensely successful for the preparation of amorphous oxide materials, offering a number of advantages including high chemical purity and homogeneity, amenability to forming many shapes (e.g. films, coatings, powders, fibers, monoliths, gels), large compositional flexibility and low temperature processing. While much of the initial work focused on the preparation of silicate based materials, more recently the development of sol-gel routes towards non-siliceous system has attracted considerable interest.

My field of research will focus on sol-gel synthesis of new non-siliceous glass such as aluminate, phosphate, tellurite glasses. Optimized preparation conditions for these new materials will be developed and their physical properties and microstructures will be characterized. The solution state chemistry and the structural evolution of sol - gel - glass will be characterized and monitored in situ using advanced high resolution liquid and solid state NMR methods.
