1. Design and Characterisation of new Anode Materials for Lithium-Ion Batteries
Abstract : Reliable ways of storing energy are crucial to support our modern way of life; lithium-ion batteries provide an attractive solution. The constant demand for higher energy density, thinner, lighter and even more mechanically flexible batteries has motivated research into new battery materials. Some of these will be explored in this thesis. READ MORE

2. Hydrogen reduction route towards the production of nano-grained alloys.- Synthesis and characterization of Fe2Mo powder
Abstract : With a view to design processes based on gas-solid reactiontowards the production of fine-grained novel alloys andintermetallics, studies of the reduction of the mixed oxides ofFe and Mo by hydrogen towards the production of Fe-Mo alloyshave been carried out in the present work. The route offersexcellent potentials toward the bulk production of nano-grainedmaterial of tailored-composition in bulk in a green processpath. READ MORE

3. Modulations in B8-type Intermetallics
Abstract : The B8-type regions of the Mn-Sn and Cu-In systems have been investigated by means of electron and X-ray diffraction. The importance of the combination of these techniques in the study of B8-type phases is pointed out. In addition to the B8-type phases an alloy with a quasicrystal approximant structure has been studied. READ MORE

4. Solving Mysteries and Outwitting Transitions : Investigating the Incommensurate Crystal Structures of AuIn and Sn3Sb2
Abstract : This thesis introduces two new incommensurate alloys. AuIn shows variable amounts of modulation, depending on the measurement temperature. At 400°C the diffraction pattern shows diffuse scattering and a thallium iodide type Cmcm space group. READ MORE

5. Temperature Dependent in situ Studies of two Simple Structure Types Revealing Modulation : or the Art of Making Glitter
Abstract : In the first part of this thesis, three intermetallic compounds are discussed, that were originally thought of as thallium iodide type compounds. Starting from small evidence that there is more than meets the eye, investigations began to find the true structure of AuIn. READ MORE
