  2. 6. Mesoporous Building Blocks : Synthesis and Characterization of Mesoporous Silica Particles and Films

    Author : Emma M. Björk; Magnus Odén; Fredik Söderlind; José Córdoba; Mika Lindén; Linköpings universitet; []
    Keywords : ;

    Abstract : Catalyst supports, drug delivery systems, hosts for nanoparticles, and solar cells are just some examples of the wide range of exciting applications for mesoporous silica. In order to optimize the performance of a specific application, controlling the material’s morphology and pore size is crucial. READ MORE

  4. 7. Colloidal suspensions of mesostructured silica

    Author : Andreas Berggren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; formation mechanism; non-ionic surfactants; silica; inorganic silica; colloidal suspension; control of particle size;

    Abstract : Mesoporous silica is a porous material with walls made of silica and pores in the size range of 2-50 nm. Since the silica most often is amorphous, the material lacks short range order but the pores may be arranged in different structures generating a long-range order. 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. Toxicological and Immunomodulatory Properties of Mesoporous Silica Particles : Applications in Life Sciences

    Author : Natalia Kupferschmidt; Alfonso E Garcia-Bennett; Susanne Gabrielsson; Mika Lindén; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mesoporous silica; biocompatibility; adjuvants; drug delivery systems; obesity;

    Abstract : Mesoporous silica particles offer great potential benefits as vehicles for drug delivery and in other biomedical applications. They present a high loading capacity due their ordered and size-tuneable pores that allow molecules to be loaded and released. READ MORE

  7. 10. Dynamics of Enzyme Immobilization in Mesoporous Silica Particles

    Author : Pegah Sadat Nabavi Zadeh; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; fluorescence spectroscopy; real-time monitoring.; fluorescence anisotropy; pore filling; Enzyme immobilization; mesoporous silica; kinetics; rotational mobility; rate of immobilization;

    Abstract : The focus of this thesis is placed on the dynamic behavior of proteins in confining environments which is studied as a scientific challenge for a deeper understanding of the immobilization mechanism and a better designing of enzyme immobilization in porous materials. Enzymes are immobilized in porous materials to improve the enzyme activity and simplify their purification from the product solution in biocatalytic applications. READ MORE
