  1. 11. Synthesis of xyloglucan oligo- and polysaccharides with glycosynthase technology

    Författare :Fredrika Gullfot; Harry Brumer; Tuula Teeri; Jerry Ståhlberg; Mats Martinelle; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glycosynthase; xyloglucan; xyloglucan endo-transglycosylase; retaining glycoside hydrolase; xyloglucanase; polysaccharide synthesis; Bioengineering; Bioteknik; Enzyme engineering; Enzymteknik; Bioorganical synthesis; Bioorganisk syntes; Biomaterials; Biomaterial;

    Sammanfattning : Xyloglucans are polysaccharides found as storage polymers in seeds and tubers, and as cross-linking glycans in the cell wall of plants. Their structure is complex with intricate branching patterns, which contribute to the physical properties of the polysaccharide including its binding to and interaction with other glycans such as cellulose.

  3. 12. On dental ceramics and their fracture : a laboratory and numerical study

    Författare :Wen Kou; Göran Sjögren; Tore Dérand; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dental ceramics; Finite element analysis; Fixed partial denture; Fracture; Numerical modeling; Surface treatment; Biomaterials; Biomaterial; odontologi; Odontology;

    Sammanfattning : Background Surface treatments and irregularities in the surfaces may affect the fracture of ceramics. The effects of various treatments on the surface texture of different types of ceramic cores/substructures was therefore qualitatively, quantitatively and numerically evaluated. LÄS MER

  4. 13. Calcium-Aluminate as Biomaterial : Synthesis, Design and Evaluation

    Författare :Jesper Lööf; Håkan Engqvist; Sture Hogmark; Elis Carlström; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Calcium-aluminate; Biomaterial; Dental materials; Vertebroplasty; Chemically Bonded Ceramics; Synthesis; Biomaterials; Biomaterial;

    Sammanfattning : In this thesis different aspects of calcium-aluminate (CA) as biomaterial are presented. Calcium aluminate is a chemically bonded ceramic with inherent properties making it suitable for use as biomaterial in some applications. LÄS MER

  5. 14. 3D Printed scaffolds as cancer microenvironment medels for drug discovery

    Författare :Jennifer Rosendahl; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D Printing; Breast cancer; Biomaterials; Drug development;

    Sammanfattning : Cancer is one of the most common diseases in the modern world and major efforts are made globally to develop new diagnostics and treatments. It originates from a cell which, at some point, has begun to divide and grow uncontrollably. The most common type is breast cancer, and like all other cancers there is a need of more efficient drug therapies. LÄS MER

  7. 15. Wood Plastic Composites made from Modified Wood : Aspects on Moisture Sorption, Micromorphology and Durability

    Författare :Kristoffer Segerholm; Ove Söderström; Magnus Wålinder; Mats Westin; Pia Larsson Brelid; Per Johan Gustafsson; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wood plastic composites; WPC; acetylation; heat treatment; furfurylation; moisture sorption; micromorphology; decay; UV laser; soil test; Biomaterials; Biomaterial;

    Sammanfattning : Wood plastic composite (WPC) materials have seen a continuous market growth worldwide in the last decade. So-called extruded WPC profiles are today mainly used in outdoor applications, e.g. decking, railing and fencing. LÄS MER
