  2. 6. Enzyme Immobilization in Mesoporous Silica

    Author : Hanna Gustafsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  4. 7. Novel Syntheses, Structures and Functions of Mesoporous Silica Materials

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

  5. 8. Formation of mesostructured silica based on non-ionic interactions

    Author : Andreas Sundblom; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mesoporous silica; non-ionic block co-polymer; SBA-15.; colloidal suspension; silica-PEO interaction; formation mechanism; inorganic silica;

    Abstract : Mesostructured silica is a material consisting of a silica matrix with an organization in the meso range of 2-50 nm. The silica matrix is most often amorphous while the organization, induced by a structure directing agent, may generate a long-range mesoorder. READ MORE

  6. 9. New Materials for Environmental Applications:Thermoelectrics and Low-Temperature Oxidation Catalysts

    Author : Ali Saramat; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; selective oxidation; Czochralski; YMn4Al8; clathrate; heterogeneous catalysis; thermoelectricity; noble metals; mesoporous; phonon glass-electron crystal; figure-of-merit ZT ;

    Abstract : New materials have been researched for environmental applications as thermoelectrics and low-temperature oxidation catalysts. One of the main objectives of this thesis was to prepare and characterize new efficient thermoelectric materials (TM’s). READ MORE

  7. 10. Nanoscale Osseointegration : Characterization of Biomaterials and their Interfaces with Electron Tomography

    Author : Kathryn Grandfield; Håkan Engqvist; Peter Thomsen; Anders Palmquist; Alexandra Porter; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electron tomography; transmission electron microscopy; hydroxyapatite; titanium; titania; bone; implant; osseointegration; interface; mesoporous; Materialvetenskap; Materials Science;

    Abstract : Bone response is one of the key determining factors in the overall success of biomaterials intended for bone regeneration and osseointegration. Understanding the formation of bone at an implant surface may lead to the improved design of biomaterials for the future. READ MORE
