  1. 21. Low Molecular Weight Organic Acids and Their Aluminium Complexes in Forest Soils

    Författare :Patrick van Hees; F. C. Ugolini; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The significance of low molecular weight (LMW) organic acids and their aluminium (Al) complexes in soil solutions of podzolized soils was examined. Methods for the analysis of these compounds and complexes were developed, and the impact of these substances on the weathering and podzolization processes was studied. LÄS MER

  3. 22. Stereo and regio controlled halogenation, and synthesis of low molecular weight carbohydrates

    Författare :Rolf Johansson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The regio- and stereoselective introduction of halogens as well as unsaturation into carbohydrates is investigated with triphenylphosphine - halide systems. Three different glycosidation methods are presented. LÄS MER

  5. 24. Synthesis and Characterization of Self-Assembling Low Molecular Weight Copolymers for Bioengineering Applications

    Författare :Jenny Fagerland; Anna Finne-Wistrand; Tim Bowden; Natalia Andronova; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cooligomers; bioengineerng applications; polymer synthesis;

    Sammanfattning : The constant need for improved biomedical materials and the interest in producing materials with similar properties to the extracellular matrix in different tissues has resulted in increasing interest in research on hydrogels. Over the last decade self-assembling copolymers have been of particular interest since they form hydrogels in response to external stimuli such as temperature. LÄS MER
