1. Novel electrolytes for next-generation hybrid supercapacitors - Investigating the interaction between electrolyte and electrode
Sammanfattning : The storage of electrical energy is of outmost importance in today’s society, ranging from cell phones to large scale energy storage of intermittent electricity sources. Batteries, that are most commonly used, struggle with low power density and limited cycle lifetime. LÄS MER
2. Multifunctional silk: from fabrication to application
Sammanfattning : Silk fibers offer untapped internal structures to template the formation of nano-objects and active coatings. So far, access to all or part of the internal and organized structures has been a significant challenge. LÄS MER
3. Studies of Catalytic Low-Temperature CO Oxidation over Cobalt Oxide and Related Transition Metal Oxides
Sammanfattning : The catalytic oxidation of carbon monoxide at low temperatures is important in many applications. The use of a low temperature active catalyst may lower the emissions during the cold-start of a car, and volatile organic compounds in exhaust gases from stationary sources might be treated without the need of preheating the gas.

4. Charge Storage mechanisms and interactions of hybrid supercapacitor electrode materials with next-generation electrolytes
Sammanfattning : The storage of electrical energy is of outmost importance in today’s society for a wide range of applications. Batteries, that are most common for electrical energy storage today, struggle with low power density and limited cycle lifetime. LÄS MER
5. Chemical Processes at the Water-Manganite (γ-MnOOH) Interface
Sammanfattning : The chemistry of mineral surfaces is of great importance in many different areas including natural processes occurring in oceans, rivers, lakes and soils. Manganese (hydr)oxides are one important group to these natural processes, and the thermodynamically most stable trivalent manganese (hydr)oxide, manganit (γ-MnOOH), is studied in this thesis. LÄS MER
