  2. 11. N-Heterocyclic Carbene Catalysis in Organic Synthesis - A Green Chemistry Approach

    Author : Linda Ta; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; aerobic oxidation; ionic liquid; sustainability; NHC catalysis; oxidative NHC catalysis; green chemistry; OTHO; Organocatalysis;

    Abstract : The twelve principles of green chemistry were created as a response to the multiple environmental issues caused by the release of waste from the chemical industry. The principles acts as a guide in the development of sustainable chemical processes for the syntheses of important molecules needed to sustain our living standards. READ MORE

  4. 12. Palladium(II)-Catalyzed Oxidative Cyclization Strategies : Selective Formation of New C-C and C-N Bonds

    Author : Andreas K. Å. Persson; Jan-Erling Bäckvall; Matthew Sigman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbocyclization; Palladium Catalysis; Oxidation; Cyclization; Enallenes; Aza-Enallenes; Dienallenes; Allenylation; Oxazolidinones; Biomimetic; Arylation; Borylation; Transmetallation; organisk kemi; Organic Chemistry;

    Abstract : The main focus of this thesis has been directed towards preparation and oxidative carbocyclization of en-, dien- and aza-enallenes.In the first part of this thesis, a stereoselective oxidative carbocyclization of dienallenes was realized. READ MORE

  5. 13. Adsorption, desorption, and redox reactions at iron oxide nanoparticle surfaces

    Author : Lelde Krumina; MEMEG; []
    Keywords : Ferrihydrite; Goethite; Secondary metabolites; Reductive dissolution; Catalytic oxidation; hydroxyl radicals; Fenton reaction; SOM decomposition;

    Abstract : Iron oxide nanoparticles are involved in several important biogeochemical processes. The interfaces between aqueous solutions and iron oxide nanoparticle surfaces are found everywhere in nature, and the chemical and microbial processes occurring at these complex interfaces control e.g. nutrient and contaminant availability and transport.

  6. 14. Retinal glucose metabolism and blood flow : Effects of photic stimulation

    Author : Lin Wang; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; blood flow; darkness; flicker; glucose oxidation; glycolysis; lactate; light; nitric oxide; optic nerve; retina; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

    Abstract : Retinal glucose metabolism was investigated under different light conditions in cats,pigs and rabbits. Glycolysis and glucose oxidation in the outer and inner parts of theretina were assessed by determining arteriovenous concentration differences foroxygen, glucose and lactate, as well as local blood flow.

  7. 15. Degradation of organic matter in wastewater -Enhanced denitrification and removal of refractory organics

    Author : Marinette Hagman; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; leachate; denitrification; carbon source; advanced oxidation; Activated sludge; wastewater; oxygen uptake rate; ozone;

    Abstract : Degradation of organic matter takes place in many processes within a wastewater treatment plant (WWTP). The need for optimisations and extended degradation processes for both organics and nitrogen will increase as outlet demands are strengthened and increasing loads are desired. READ MORE
