1. Studies on Rechargeable Fe-air electrodes in Alkaline electrolyte
Sammanfattning : Energy storage system is an important component in the energy system based on variable renewable energy sources into the grid. Energy storage system could contribute to decarbonization, energy security, offset the demand and supply of the electricity sector, especially for the electric grid. LÄS MER
2. Colloidal fumed silica and soluble silicates — Interactions and microstructure
Sammanfattning : Colloidal dispersions and gels are important material systems with applications in many industrial processes and consumer products. This thesis aims at increasing the understanding of colloidal interactions and the phase transition from a colloidal dispersion to an arrested structure in two systems based on silica. LÄS MER
3. Rechargeable Aqueous Batteries Based on Available Resources : Investigation and Development towards Efficient Battery Performance
Sammanfattning : Batteries employing water based electrolytes enable extremely low manufacturing costs and are inherently safer than Li-ion batteries. Batteries based on zinc, manganese dioxide, iron, and air have high energy relevancy, are not resource restricted, and can contribute to large scale energy storage solutions. LÄS MER
4. From Facets to Flow: The Electrooxidation of Glycerol on Pd-based catalysts
Sammanfattning : Glycerol, a by-product of biodiesel refineries, has uses in industries such as cosmetics, food, and pharmaceuticals. However, its usage is small compared to the amount of glycerol produced from biodiesel production. LÄS MER
5. Structure and Dynamics of Silica Dispersions and Gels
Sammanfattning : This thesis deal with the sol-gel transition of two quite different systems, both based on silica. The overall aim is to understand what interactions lead to this sol-gel transition and how the structure and dynamics change as a result of this.The first project concern the gelation of water glass, also known as alkaline sodium silicate solutions.
