    Detta är en avhandling från KFS AB

    Författare :Christian Persson; Lund University.; Lunds universitet.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymerteknik; biopolymers; Kemiteknik och kemisk teknologi; Polymer technology; Chemical technology and engineering; Materiallära; materialteknik; Material technology; Makromolekylär kemi; Macromolecular chemistry; proton-exchange membrane fuel cell; structure diffusion; thiol-ene reaction; segmental mobility; high temperature; benzimidazole; block copolymers; polymer electrolyte; anhydrous proton conductivity;

    Sammanfattning : Proton transport is a fundamental process that can be found in many systems in nature, as well as in technical devices, such as fuel cells, electrochromic devices and various types of sensors. Fuel cell technology is considered as environmentally friendly because fuel cells are not limited by the Carnot cycle, and efficiently converts chemical energy into electrical energy which can be used for powering cars, laptops, buildings etc. LÄS MER

  4. 4. Ru-Based Water Oxidation Catalysts Development and Mechanistic Studies

    Detta är en avhandling från Stockholm : Department of Organic Chemistry, Stockholm University

    Författare :Andrey Shatskiy; Stockholms universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ruthenium; catalysis; water oxidation; artificial photosynthesis; Organic Chemistry; organisk kemi;

    Sammanfattning : Oxidation of water constitutes one of the most challenging processes in artificial photosynthesis, which aims at storing solar energy in the form of chemical bonds of high-energy fuels. To facilitate this process, efficient and durable water oxidation catalysts have to be developed and integrated into the complete photosynthetic cells. LÄS MER
