  2. 1. Enzyme immobilization in mesoporous silica

    Author : Hanna Gustafsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pH probe; Mesoporous silica; particle morphology; immobilization; pore size; quartz crystal microbalance with dissipation monitoring; enzyme; biocatalysis;

    Abstract : Enzymes are highly effective and versatile biological catalysts, with a high chemo-, stereo- and regioselectivity while operating under mild conditions, such as physiological temperature and pH and atmospheric pressure. Therefore, enzymes are a sustainable alternative to conventional catalysts in organic synthesis processes. READ MORE

  4. 2. Atom Probe Tomography Investigations of Biologically Relevant Nanoparticles

    Author : Gustav Eriksson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface modification; Nanoparticles; silica; hydroxyapatite; electron microscopy; ligands; atom probe tomography; titanium;

    Abstract : The study of materials at the nanoscale is essential in many scientific disciplines. For example, in materials science the size of the building blocks of a material is directly linked to its properties. READ MORE

  5. 3. 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

  6. 4. Housing Aquaporins in Nanostructured Glass

    Author : Simon Isaksson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membrane protein; Water; Interface; Aquaporin; Silica; Formation; Silicification;

    Abstract : Proteins are a group of biomolecules that perform versatile tasks, which in many cases are essential for life. The magnitude of their importance is perhaps expressed by the word protein itself, coined by the Swedish chemist Jöns Jacob Berzelius in the summer of 1838. READ MORE

  7. 5. From Silica Nano-Particles to Silica Gels and Beyond - Salt Induced Aggregation of Silica Nano-Particles and the Stability of Resultant Gels

    Author : Christian Sögaard; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Silica; Nanoparticles; grouting; Specific ion effects; Nanomaterial;

    Abstract : Aqueous silica nanoparticle suspensions are widely available and used within a number of industries. A relatively new area of application is as a grouting material for sealing narrow fractures in tunnels. READ MORE
