  1. 1. Catalysts for Oxygen Production and Utilization Closing the Oxygen Cycle: From Biomimetic Oxidation to Artificial Photosynthesis

    University dissertation from Stockholm : Department of Organic Chemistry, Stockholm University

    Author : Erik Karlsson; Stockholms universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; oxygen; catalytic oxidation; biomimetic oxidation; artificial photosynthesis; water oxidation; DFT calculations; NATURAL SCIENCES Chemistry Organic chemistry; NATURVETENSKAP Kemi Organisk kemi; Organic Chemistry; organisk kemi;

    Abstract : This thesis describes the development and study of catalysts for redox reactions, which either utilize oxygen or hydrogen peroxide for the purpose of selectively oxidizing organic substrates, or produce oxygen as the necessary byproduct in the production of hydrogen by artificial photosynthesis.The first chapter gives a general introduction about the use of environmentally friendly oxidants in the field of organic synthesis, and about the field of artificial photosynthesis.

  3. 3. Innovative Oxygen Carriers for Chemical-looping Combustion

    University dissertation from Göteborg

    Author : Dazheng Jing; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical-looping with oxygen uncoupling; Combined manganese oxides; Chemical-looping combustion; CuO-based oxygen carrier; Oxygen carrier;

    Abstract : Chemical-looping combustion (CLC) and chemical-looping with oxygen uncoupling (CLOU) are combustion technologies where carbon dioxide is inherently obtained in pure form without any gas separation step. In the processes, fuel is introduced to the fuel reactor and combustion air is introduced to the air reactor. READ MORE

    Abstract : Popular Abstract in Swedish Effekter av narkosgas, låg syrgashalt och blodförlust under blodspädning (hemodilution) på sövda grisar. Blodspädning (hemodilution) används under operation för att minska behovet av blodtransfusion med dess inneboende risker. READ MORE

  5. 5. Oxygen Vacancy Chemistry in Ceria

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jolla Kullgren; Uppsala universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ceria; Density Functional Theory; Oxygen storage; Nano crystals; Sulfur poisoning; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Abstract : Cerium(IV) oxide (CeO2), ceria, is an active metal oxide used in solid oxide fuel cells and for the purification of exhaust gases in vehicle emissions control. Behind these technically important applications of ceria lies one overriding feature, namely ceria's exceptional reduction-oxidation properties. READ MORE
