1. 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

2. Structural Investigations of Complex Glasses by Solid-state NMR
Abstract : This PhD thesis presents structural investigations of amorphous inorganic materials: oxide and oxynitride glasses and mesoporous bioactive glasses (MBGs), by solid-state Nuclear Magnetic Resonance (NMR). Lanthanum oxide and oxynitride [La-Si-(Al)-O-(N)] glasses have a large number of potential applications due to their physical properties. READ MORE

3. 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

4. Crystallization of glasses in the system (Zr)-Y-Si-Al-O-(N)
Abstract : Glass is a group of materials that has been used for structural and functional purposes for many centuries. Nevertheless, interest in the science and technology of glass has expanded significantly in recent years as a result of the need to develop new materials for advanced applications. READ MORE
