1. Structural Dynamics of Glass-Forming Liquids
Abstract : Neutron and light scattering experiments on glass-forming liquids, an oxide network, a polymeric system and a polymeric electrolyte, were performed. The network glass-former B2O3 was investigated from 60 - 1300 K. The experimental results were interpreted using mode coupling theory and the soft potential model. READ MORE

2. Preparation, characterization and properties of nitrogen rich glasses in alkaline earth-Si-O-N systems
Abstract : Nitrogen rich glasses in the systems Ca-Si-O-N, Sr-Si-O-N and AE-Ca-Si-O-N (AE = Mg, Sr and Ba) have been prepared using a novel glass-synthesis route. The limits of the glass forming regions in the Ca and Sr systems and substitution limits in the AE-Ca-Si-O-N systems have been determined and physical properties of the glasses measured. READ MORE

3. Dynamics of biological membranes and associated water
Abstract : An ingenious assembly of biomolecules and water constitute what we call biological tissue. The presence of water in this assembly is fundamental for the physiological processes and can make the difference between life and death. READ MORE

4. Computer Simulations of Simple Liquids with Tetrahedral Local Order : the Supercooled Liquid, Solids and Phase Transitions
Abstract : The understanding of complex condensed matter systems is an area of intense study. In this thesis, some properties of simple liquids with strong preference for tetrahedral local ordering are explored. These liquids are amenable to supercooling, and give complex crystalline structures on eventual crystallisation. READ MORE

5. Novel Route of Oxynitride Glass Synthesis and Characterisation of Glasses in the Ln-Si-O-N and Ln-Si-Al-O-N Systems
Abstract : The present work has been primarily focused on the glass forming region in the La-Si-O-N system, and attempts have been made to find glass forming regions by adopting a new synthesis route to produce glasses in oxynitride system. This goal can be attained by adding a network modifier in its metallic form instead of as an oxide. READ MORE
