1. Application of Rare-Earth Doped Ceria and Natural Minerals for Solid Oxide Fuel Cells
Abstract : Although solid oxide fuel cell (SOFC) technology exhibits considerable advantages as compared to other energy conversion devices, e.g. high efficiency, low emission and fuel flexibility, its high operating temperature leads to rapid component degradation and has thus hampered commercialization.

2. Magnetism in Band Gap Engineered Sputtered MgxZn(1-x)O Thin Films
Abstract : This dissertation presents a comprehensive study of the intrinsic room temperature ferromagnetism, RTFM, in technologically important thin films of ZnO, MgO, Mg@ZnO, the so-called d0–magnets that do not contain any intrinsic magnetic elements. We also present the first report on magnetism in Mn doped MgO films fabricated by dc magnetron sputtering. READ MORE

3. Synthesis, Structure and Proton Conduction of Substituted BaTiO3 and BaZrO3 Perovskites
Abstract : Proton conducting oxides can be beneficial as electrolyte materials in devices such as fuel cells, hydrogen sensors etc. Proton conducting fuel cells (PCFCs), utilising H2 as fuel, stand out as a promising technology for future clean energy generation. READ MORE

4. Density Functional Theory Applied to Materials for Spintronics
Abstract : The properties of dilute magnetic semiconductors have been studied by combined ab initio, Monte Carlo, and experimental techniques. This class of materials could be very important for future spintronic devices, that offer enriched functionality by making use of both the spin and the charge of the electrons. READ MORE

5. Novel room temperature ferromagnetic semiconductors
Abstract : In today's information world, bits of data are processed bysemiconductor chips, and stored in the magnetic disk drives.But tomorrow's information technology may see magnetism (spin)and semiconductivity (charge) combined in one 'spintronic'device that exploits both charge and 'spin' to carry data (thebest of two worlds).
