1. Electrochemistry of Heme Containing Enzymes - Fundamentals and Applications
Sammanfattning : The thesis is a bioelectrochemical study of heme enzymes, mainly peroxidases and cellobiose dehydrogenases (CDH). It covers both fundamental and applied aspects, viz. studies of the direct electron transfer and kinetics of enzymes on electrodes, and the development of amperometric enzyme-based biosensors.

2. Aqueous Organic Redox Flow Batteries - Electrochemical Studies of Quinonoid Compounds
Sammanfattning : Society faces a large challenge in transitioning to sustainably generating electricity from renewable energy sources such as wind and solar. One of the biggest obstacles to this transition is the intermittence of the sources, leading to a mismatch of supply and demand, a problem most commonly solved by installing large‐scale energy storage.

3. 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
4. Studies of Electrocatalytic Reactions of NADH at Mediator Modified Electrodes and of H2O2 at Peroxidase Modified Electrodes
Sammanfattning : This thesis addresses: (1) studies of direct and mediated electron transfer and kinetics of peroxidases on electrodes and the development of amperometric peroxidase-based biosenors, (2) electrochemical and kinetic studies of NADH oxidation at mediator modified electrodes. The direct and mediated electron transfer of horseradish and tobacco peroxidase were investigated on graphite electrodes by using wall-jet electrode methodology. LÄS MER
5. Critical potential and oxygen evolution of the chlorate anode
Sammanfattning : In the chlorate process, natural convection arises thanks to the hydrogen evolving cathode. This increases the mass transport of the different species in the chlorate electrolyte. There is a strong connection between mass transport and the kinetics of the electrode reactions. LÄS MER
