1. Solution-Chemical Synthesis of Cobalt and Iron:Zinc Oxide Nanocomposite Films
Sammanfattning : The potentially most important challenges today are related to energy and the environment. New materials and methods are needed in order to, in a sustainable way, convert and store energy, reduce pollution, and clean the air and water from contaminations. LÄS MER
2. Synthesis, Characterization, and Evaluation of Ag-based Electrical Contact Materials
Sammanfattning : Ag is a widely used electrical contact material due to its excellent electrical properties. The problems with Ag are that it is soft and has poor tribological properties (high friction and wear in Ag/Ag sliding contacts). LÄS MER
3. Thermodynamic modelling of aqueous solutions and applications in some functional materials synthesis
Sammanfattning : Modern advances in science and technology require thedevelopment of functional materials with improved performance.Such engineered materials often have a very complex compositionand specific microstructures. These factors impose a seriouschallenge for the synthesis and processing of advancedfunctional materials. LÄS MER
4. Carbothermal synthesis of nano-structured metal, carbides and nitrides, using solution processed precursors; from precursor to product
Sammanfattning : This thesis describes how solution chemical based carbothermal syntheses can be used for the synthesis of nanostructured zirconium carbide and nitride nanophase powders as well as a nickel-metal coating on NbC for use as a sintering agent. The focus is on the development of novel synthesis routes using atomic or small nanoscale level mixing of the metal oxide and carbon source in the starting precursors, enabling the use of lower synthesis temperatures and non-agglomerated nanosized powders.
