1. Phase transformation and stability studies of the Zr-H system
Abstract : Zirconium alloys are widely used in the nuclear industry because of their high strength, good corrosion resistance and low neutron absorption cross-section. Zirconium has a strong affinity for hydrogen, however, and if hydrogen concentration builds up, the material will gradually degrade. READ MORE

2. Transition Metal Hydride Complexes and Hydrogenated Gallium Clusters : Synthesis and Structural Properties
Abstract : Synthesis and structural characterisation of metal hydrides in two important systems are presented. The first system presented is low valent cobalt and nickel complex hydrides with the compositions BaMg5Co2H10, RbMg5CoNiH10, SrMg2CoH7and Sr4Mg4Co3H19 featuring nickel with oxidation state of 0 and cobalt with oxidation state +I and -I.

3. Synthesis, Properties and Bonding in Hume-Rothery Transition-metal Gallides and Indides
Abstract : In this work the intermetallic systems formed by transition-metals from group 5 to 9 with Ga, In and Zn have been experimentally and theoretically studied in detail. Syntheses, compositional analyses, X-ray and neutron diffraction (single crystal as well as powder) and measurements of physical properties, e.g. READ MORE

4. Tungstate Scintillators Growth, Structures and Properties
Abstract : Tungstate crystals are well-known scintillators, which can be used as detector material for high-energy radiation and are often chosen as references in measurements on new luminescent materials. For measurements of excitation and relaxation properties, single crystals are desirable. READ MORE

5. Structural and Electrical Transport Properties of Doped Nd-123 Superconductors
Abstract : It is generally believed that one of the key parameterscontrolling the normal state and superconducting properties ofhigh temperature superconductors is the charge carrierconcentrationpin the CuO2planes.By changing the non-isovalent dopingconcentration on the RE site as well as the oxygen content in(RE)Ba2Cu3O7−δ, an excellent tool is obtained tovary the hole concentration over a wide range from theunderdoped up to the overdoped regime.
