    Författare :Caroline Häggström; Mats Lindblom; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Sammanfattning : The common European Energy and Climate policy states that in 2020 the share of biofuels for inland transports should be 10 %. Such a stipulation calls for a commercially sustainable biofuel production. LÄS MER

  3. 12. Nanostructured Ceramics - Synthesis and Understanding

    Författare :Farnaz Ghajeri; Wei Xia; Freddy Kleitz; Uppsala universitet; []
    Nyckelord :Material Science; Nanoporouse Silica; Calcium Phosphate; Synthesis; Characterization; Adsorption; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : During the last years, nanostructured ceramics have been favored for use in the industry due to their beneficial properties. For example, calcium phosphate ceramics with their biocompatible and bioactive characteristics are beneficial in biomedicine. LÄS MER

  4. 13. Exploring the structure of oligo- and polysaccharides : Synthesis and NMR spectroscopy studies

    Författare :Hanna Jonsson; Göran Widmalm; Antonio Molinaro; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbohydrates; NMR spectroscopy; synthesis; lipopolysaccharides; conformational studies; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : A deeper understanding of the diversity of carbohydrates and the many applications of oligo- and polysaccharides found in nature are of high interest. Many of the processes involving carbohydrates affect our everyday life. This thesis is based on six papers all contributing to an extended perspective of carbohydrate property and functionality.

  5. 14. Synthesis of Ring-fused Peptidomimetics : Interacting with Amyloid Fibrils

    Författare :Dan E. Adolfsson; Fredrik Almqvist; Anna Linusson; Morten Grötli; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organic chemistry; synthesis; peptidomimetics; thiazoline fused 2-pyridones; Alzheimer s disease; Parkinson s disease; Amyloid; Amyloid-beta; alfa-Synuclein; method development; organisk kemi; Organic Chemistry;

    Sammanfattning : Parkinson's and Alzheimer's disease are the two most common neurological disorders in humans. Both conditions involve progressive death of neurons in the central nervous system, decline in bodily functions and eventually (and invariably), death. So far, no cure exists and the available treatments can only ease symptoms. LÄS MER

  7. 15. Asymmetric Synthesis of C-Glycosylated Amino Acids : Incorporation in Collagen Glycopeptides and Evaluation in a Model for Rheumatoid Arthritis

    Författare :Tomas Gustafsson; Jan Kihlberg; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Total synthesis; stereoselective synthesis; chiral glycine templates; Evan’s alkylation; asymmetric hydrogenation; alpha-amino acid synthesis; C-glycoside; rheumatoid arthritis; MHC; T cell; Organic chemistry; Organisk kemi;

    Sammanfattning : This thesis describes stereoselective syntheses of four amino acids, three of which are C-glycosidic analogues of glycosylated amino acids. The overall goal of the project was to probe the interactions between MHC molecules, glycopeptide antigens and T cell receptors, that are essential for development of collagen induced arthritis.
