1. 1. Extraction Properties of some Nitrogen-Containing Extractants and Determination of Nitrate Complex Formation for Lanthanides and Selected Actinides Using Solvent Extraction

   Författare :Sofie Andersson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; actinides; solvent extraction; separation; lanthanides; nitrate complex formation;

   Sammanfattning : Partitioning and transmutation of spent nuclear fuel will reduce the amount of waste and its radiotoxicity in a long-term perspective. At the same time the energy content of the spent nuclear fuel can be used more efficiently by recycling of uranium and plutonium and by using energy from the transmutation reactor. LÄS MER

3. 2. Atmospheric Chemistry of Volatile Organic Compounds: Oxidation Products, Mechanisms and Secondary Organic Aerosol Formation

   Författare :Julia Hammes; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SOA; VOC; anthropogenic; biogenic; FIGAERO; CIMS; HOMs; ELVOCs; atmospheric oxidation; chemical mechanism; NOx; limonene; a-pinene; TMB; ozone; nitrate; OH; radical chemistry; RO2; G-FROST; GO:PAM;

   Sammanfattning : The results from this work are a piece in understanding the complex puzzle of atmospheric aerosol formation. Secondary organic aerosol (SOA) formed by the oxidation of volatile organic compounds (VOC) in the atmosphere is a key component of air pollution with a strong negative impact on human health and influence on climate, but its formation is poorly understood.

4. 3. Heme-copper oxidases and nitric oxide : Reaction mechanisms and supercomplex formation

   Författare :Ingrid Albertsson; Pia Ädelroth; Alessandro Giuffrè; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Heme-copper oxidase; nitrite reductase; nitric oxide reductase; nitric oxide; supercomplex; Paracoccus denitrificans; denitrification pathway; proton transfer pathway; C-type oxidase; Helicobacter pylori; Biochemistry; biokemi;

   Sammanfattning : In the denitrification process where nitrate is stepwise reduced to nitrogen gas, the toxic molecule nitric oxide (NO) is formed as an intermediate. Nitric oxide is produced by the enzyme cd1 Nitrite reductase (cd1NiR) by reduction of nitrite and is later reduced to nitrous oxide by nitric oxide reductase (cNOR). LÄS MER

7. 5. Mononuclear Ruthenium Complexes that Catalyze Water to Dioxgen Oxidation

   Författare :Lianpeng Tong; Licheng Sun; Randolph Thummel; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ruthenium complex; Homogeneous catalysis; Water oxidation; O2 evolution; anionic ligand; Molecular catalyst; Electrocatalysis; Kinetics; Artificial photosynthesis; Light-driven; Immobilization of catalyst;

   Sammanfattning : The theme of this thesis is the development of mononuclear Ru-based complexes that are capable of catalyzing the water oxidation (or O2-evolving) reaction, e.g. 2 H2O → O2 + 4 H+ + 4 e−. Several families of mononuclear Ru water oxidation catalysts were designed and prepared. LÄS MER
