  1. 56. degradable electroactive polymers: Synthesis, Macromolecular architecture and scaffold design

    Författare :Baolin Guo; Ann-Christine Albertsson; Patric Jannasch; KTH; []
    Nyckelord :Poly lactide ; poly ε-caprolactone ; ring-opening polymerization; carboxyl-capped aniline trimer; carboxyl-capped aniline pentamer; phenyl amino-capped aniline tetramer; coupling reaction; DCC DMAP system; degradability; electroactivity; conductivity; macromolecular architecture; chitosan; hydrogel; block copolymer; functionalization; oxidative coupling reaction; self-assembly; toxicity; tubular porous scaffold; neural tissue engineering.;

    Sammanfattning : Electrically conducting polymers induce specific cellular responses at the molecular level. One of the crucial limitations of the use of conducting polymers in tissue engineering is their inability to degrade. LÄS MER

  4. 58. Life Cycle Assessment (LCA) of Industrial Milk Production

    Författare :Merete Høgaas Eide; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dairy; cleaning; sustainability; packaging; LCA; Life Cycle Assessment; toxicity; milk;

    Sammanfattning : Life Cycle Assessment (LCA) was applied to milk production and processing in a study of the Norwegian dairy industry. This method, LCA, is used to assess the potential environmental impact of a material, product or service throughout its entire life cycle, from the extraction of the raw materials, the production process, and the user phase, to the final disposal.

  5. 59. Exploring Novel Catalytic Chalcogenide Antioxidants

    Författare :Henrik Johansson; Lars Engman; Helena Grennberg; Troels Skrydstrup; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; antioxidant; tellurium; selenium; catalytic; toxicity; ROS; neutrophil; glutathione peroxidase mimic; macrophage.; Organic chemistry; Organisk kemi; Kemi med inriktning mot organisk kemi; Chemistry with specialization in Organic Chemistry;

    Sammanfattning : This thesis is concerned with the synthesis and evaluation of regenerable chalcogen containing antioxidants. Variously substituted 2,3-dihydrobenzo[b]selenophene-5-ol antioxidants were evaluated in order to gain information about structure/reactivity-relationships. LÄS MER

  7. 60. Neonatal Exposure to Highly Brominated Diphenyl Ethers and Perfluorinated Compounds : Developmental Dependent Toxicity and Interaction

    Författare :Niclas Johansson; Per Eriksson; Anders Fredriksson; Henrik Viberg; Hellmuth Lilienthal; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Ecotoxicology; ekotoxikologi;

    Sammanfattning : This thesis investigated the developmental neurotoxic effects of neonatal exposure to highly brominated diphenyl ethers (PBDEs) and perfluorinated compounds (PFCs), alone or in combinations, during a critical period of the brains’ rapid growth and development, in mice. The compounds investigated were the decaBDE (PBDE 209), nonaBDE (PBDE 206), octaBDE (PBDE 203), heptaBDE (PBDE 183), and three PFCs, PFOS, PFOA, and PFDA. LÄS MER
