1. A thermostable alkaline protease from a new alkaliphilic Nesterenkonia sp
Sammanfattning : This thesis concerns a novel alkaline protease produced by an extremophilic microbial specie, designated as AL20, isolated from a feather sample collected at the shore of the alkaline soda lake Abjata in the Ethiopian Rift Valley. The isolate is a heterotrophic, alkaliphilic, halotolerant gram-positive, strictly aerobic, non-motile, non-spore forming bacterium. LÄS MER
2. Electrochemical water splitting based on metal oxide composite nanostructures
Sammanfattning : The occurrence of available energy reservoirs is decreasing steeply, therefore we are looking for an alternative and sustainable renewable energy resources. Among them, hydrogen is considered as green fuel with a high density of energy. LÄS MER
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. Poly(phenylene oxide)s functionalized with cationic side chains: design, synthesis and properties as anion exchange membranes
Sammanfattning : Anion exchange membrane fuel cells (AEMFCs) are considered as one of the most important next-generation energy conversion technologies. AEMFCs convert chemical energy into useful electrical energy and have great potential forachieving high conversion efficiencies. LÄS MER
5. Exploring N-alicyclic quaternary ammonium functional polymers as hydroxide exchange membranes
Sammanfattning : As the global power generation is shifted toward renewable and intermittent sources, the importance of fuel cells and other energy storage and conversion devices is continually increasing. However, many of these technologies are still under development and further research is necessary before they can be implemented. LÄS MER
