  1. 6. Carbon Emissions from Western Siberian Inland Waters

    Författare :Svetlana Serikova; Jan Karlsson; Oleg S. Pokrovsky; Hjalmar Laudon; Peter Raymond; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; carbon; carbon dioxide; methane; carbon emissions; river; lake; inland waters; permafrost; Siberia; Limnology; limnologi;

    Sammanfattning : Inland waters (i.e. rivers, streams, lakes, ponds) emit carbon (C) into the atmosphere. The magnitude of global inland water C emission has been estimated to equal the global ocean C sink, thus making inland waters an important component of the global C cycle. LÄS MER

  3. 7. Fullerene-like carbon nitride thin solid films

    Författare :Jörg Neidhardt; Brian C. Holloway; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The subject of this thesis is to establish synthesis-structure-property- performance relations for nano structured carbon nitride thin solid films. This material consists of bent and frequently intersecting nitrogen-containing graphite basal planes, where nitrogen plays an important role for the initiation of inter-planar cross-links and the induction of curvature via pentagon formation, much like in Buckminster Fullerenes - hence, the terminology "fullerene-like carbon nitride".

  4. 8. Carbon Nitride : Characterization and Protein Interactions

    Författare :Torun Berlind; Hans Arwin; Pentti Tengvall; Hans Hultman; Thomas E. Tiwald; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This thesis concerns synthesis and characterization of carbon-based materials and theinvestigation of the possible use, of a selection of these materials, in biomedicalapplications. Protein adsorption and blood plasma tests were used for this purposeutilizing a surface sensitive technique called spectroscopic ellipsometry. LÄS MER

  5. 9. The Mussel Adhesive Protein (Mefp-1) : A GREEN Corrosion Inhibitor

    Författare :Fan Zhang; Jinshan Pan; Douglas C. Hansen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbon steel; mussel adhesive protein; Mefp-1; inhibitor; adsorption; film forming; complexation; cross-linking; ceria nanoparticle; composite film; EIS; AFM; QCM-D; ATR-FTIR; Confocal Raman Micro-spectroscopy; DFT calculation;

    Sammanfattning : Corrosion of metallic materials is a natural process, and our study shows that even in an alkaline environment severe corrosion may occur on a carbon steel surface. While corrosion cannot be stopped it can be retarded. LÄS MER

  7. 10. Microwave-Assisted Synthesis of C2-Symmetric HIV-1 Protease Inhibitors : Development and Applications of In Situ Carbonylations and other Palladium(0)-Catalyzed Reactions

    Författare :Johan Wannberg; Anders Hallberg; David C. Rees; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; HIV; protease inhibitors; palladium; carbonylations; molybdenum hexacarbonyl; dihydropyrimidone; DHPM; microwave; cross-coupling; diazylhydrazines; carbon monoxide; synthesis; C2-symmetric; HIV-1 protease inhibitors; aminocarbonylation; fluorous; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi;

    Sammanfattning : The HIV protease is an essential enzyme for HIV replication and constitutes an important target in the treatment of HIV/AIDS. Efficient combination therapies using inhibitors of the reverse transcriptase and protease enzymes have led many to reevaluate HIV infections from a terminal condition to a chronic-but-manageable disease in the developed world.
