    Abstract : Ceramics are distinguished from metals and polymers by their inorganic nature and lack of metallic properties. They can be highly crystalline to amorphous, and their physical and chemical properties can vary widely. READ MORE

  4. 2. Characterization of some natural and synthetic materials with silicate structures

    Author : Edwin Escalera; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Konstruktionsmaterial; Engineering Materials; Materialteknik; Engineering Materials;

    Abstract : The present thesis deals with characterization of silicate structures with a determined morphology and structure such as ordered mesoporous silica and layered silicates. Mesoporous silica groups are amorphous solids exhibiting highly ordered pore structures with narrow pore size distributions and large surface areas. READ MORE

  5. 3. Novel Syntheses, Structures and Functions of Mesoporous Silica Materials

    Author : Rambabu Atluri; Alfonso E Garcia-Bennett; Maria Strömme; Paul Wright; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Materials science; Teknisk materialvetenskap; Materialvetenskap; Materials Science;

    Abstract : The field of mesoporous silica has been studied for about 20 years but it is still an area attracting a lot of attention. The use of novel templating molecules and several issues related to the synthesis and fine structural details are still poorly understood. READ MORE

  6. 4. Enzyme Immobilization in Mesoporous Silica

    Author : Hanna Gustafsson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; immobilization; lipase; Mesoporous; particle morphology; feruloyl esterase; enzyme; encapsulation; silica; pore size; trypsin;

    Abstract : Catalysts are widely used in many industries for production of chemicals, pharmaceuticals, fuels and energy. There is a need for more sustainable production processes, with reduced energy and raw material consumption together with a reduction in waste and toxic by-products. READ MORE
