  1. 36. Recombinant amelogenin - Strategies for purification and protein processing

    Författare :Johan Svensson Bonde; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Recombinant amelogenin; protein purification; fusion protein; purification tag; enamel; hydroxyapatite; matrix protein; dental regeneration; wound healing; bone formation;

    Sammanfattning : Amelogenin is an extracellular matrix protein involved in formation of enamel during early tooth development. By interacting with the forming enamel crystallites amelogenin affects their growth, so that highly elongated hydroxyapatite crystals are formed. LÄS MER

  3. 37. Growth and characterization of TiN/SiNx multilayer thin films

    Författare :Hans Söderberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Materials; Materialteknik;

    Sammanfattning : The demands from industry for higher cutting speeds, feeding rates, and reduction of the use of cooling agents during turning and milling operations are increasing. Consequently the requirements on the cutting inserts are increasing and new advanced coatings that can withstand the higher temperatures and larger loads are highly sought after. LÄS MER

  4. 38. A study on nanophase functional materials : high Tcsuperconductors and Zinc Oxide

    Författare :Lingna Wang; KTH; []
    Nyckelord :;

    Sammanfattning : Nanophase materials are an active materials research topicthat has received a great deal of attention over the past fewyears. Tlus mesis deals mainly with the synthesis, processing,and characterization of nanophase functional materials. Twotypes of functional materials were considered: high temperaturesuperconducting oxides (HTSC) and Wnc oxide. LÄS MER
