    Abstract : Lignocellulosic biomass is believed to serve a prominent role in tomorrow’s sustainable energy and material development. Among the polysaccharide fractions of lignocellulosic biomass, the potential of hemicelluloses as a valuable material resource is increasingly recognized. READ MORE

  5. 3. Free radicals in cellular pathology : Mechanisms behind lipofucin formation in cultured myocardial cells

    Author : Rasi Marzabadi Massoud; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Lipofuscin, or age pigment, may be defined as a yellowish-brown,autofluorescent, protein and lipid containing pigment that accumulates inthe lysosomal vacuome of a variety of post-mitotic cell types in man andanimals during aging. Lipofuscin is the end product of peroxidation,fragmentation and polymerization of proteins and lipids. READ MORE

  6. 4. Dendrimers and dendronized polymers : synthesis and characterization

    Author : Andreas Nyström; Anders Hult; A. Dieter Schlüter; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dendrimers; dendronized polymers; atom transfer radical polymerisation; ring-opening metathesis polymerization; reversible addition-fragmentation chain transfer polymerization; 2; 2-bis methylol propionic acid; tri-block copolymers; rheology; differential scanning calorimerty; 1H-NMR self-diffusion; Polymer chemistry; Polymerkemi;

    Abstract : The goal of this work was to synthesize complex macromolecular architectures such as dendrimers and dendronized polymers, and evaluate the effect from the dendrons on the optical and material properties. The work presented in this doctoral thesis, Dendrimers and Dendronized Polymers - Synthesis and Characterization, is divided into one minor and one major part. READ MORE

  7. 5. Functional Degradable Polymers by a Radical Chemistry approach

    Author : Jenny Undin; Ann-Christine Albertsson; Anna Finne-Wistrand; Jukka Seppälä; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : One class of polymers that is inherently of great value for many applications is the aliphatic polyesters. Such polymers are very suitable for use as temporary guides, scaffolds, for tissue formation and other biomedical applications, due to their biocompatibility, degradability and appropriate mechanical properties.
