6. Microstructure technology in silicon, quartz, and diamond
Sammanfattning : Microstructure technology can be defined as a set of fabrication processes enabling three-dimensional structures featuring dimensions in the micrometer to millimetre range, with micrometer accuracy. Microstructures can be assembled or manufactured integrated with other structures and/or microelectronics forming complex microsystems. LÄS MER
7. Exploration of Non-Aqueous Metal-O2 Batteries via In Operando X-ray Diffraction
Sammanfattning : Non-aqueous metal-air (Li-O2 and Na-O2) batteries have been emerging as one of the most promising high-energy storage systems to meet the requirements for demanding applications due to their high theoretical specific energy. In the present thesis work, advanced characterization techniques are demonstrated for the exploration of metal-O2 batteries. LÄS MER
8. Design and Characterisation of new Anode Materials for Lithium-Ion Batteries
Sammanfattning : 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. LÄS MER
9. Organic functionalization of graphene for applications in energy storage devices and optoelectronics
