  1. 11. Mesoporous Silica Particles for a Potential Therapeutic Application

    Författare :Muhammad Naeem Iqbal; Niklas Hedin; Tore Bengtsson; Mirva Eriksson; Jessica Rosenholm; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mesoporous silica; SBA-15; amylase; lipase; electron microscope; adsorption; type 2 diabetes; materialkemi; Materials Chemistry;

    Sammanfattning : Mesoporous silica particles (MSPs) have a high surface area, pore volume, and tunable pore size and surface properties, which makes them ideal for advanced therapeutic, biocatalytic, separation, and drug delivery applications. The work in this thesis shows that MSPs can be employed for therapeutic applications with minimal risk of adverse consequences. LÄS MER

  3. 12. Mesoporous magnesium carbonate : Synthesis, characterization and biocompatibility

    Författare :Sara Frykstrand Ångström; Maria Strømme; Johan Gómez de la Torre; Natalia Ferraz; Mika Lindén; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mesoporous; magnesium carbonate; pore size control; cytotoxicity; in vivo; skin irritation; acute systemic toxicity; hemocompatibility; Ca2 uptake; solubility enhancement; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Sammanfattning : Mesoporous materials constitute a promising class of nanomaterials for a number of applications due to their tunable pore structure. The synthesis of most mesoporous materials involves a surfactant liquid crystal structure to form the pores. LÄS MER

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

    Författare :Edwin Escalera; Farid Akhtar; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Konstruktionsmaterial; Engineering Materials; Materialteknik; Engineering Materials;

    Sammanfattning : 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. LÄS MER

  5. 14. Transition metal ion-chelating ordered mesoporous carbons as noble metal-free fuel cell catalysts

    Författare :Johanna Dombrovskis; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mesoporous materials; electrocatalysis; EXAFS spectroscopy; fuel cell; transition metals; carbon;

    Sammanfattning : Polymer electrolyte membrane fuel cells offer promising possibilities for clean and efficient chemical to electrical energy conversion, though their high price makes them financially unappealing. This is to a large part due to the high cost of the noble metal catalyst used in fuel cells, which makes development of new, cheap and active catalyst materials necessary. LÄS MER

  7. 15. Mesoporous Implants for Localized Controlled Drug Delivery

    Författare :Johan Karlsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; release kinetics; mesoporous titania; biomineralization; drug delivery; Biomedical implants; osseointegration; osteoporosis drugs; nanotopography; stem cells homing;

    Sammanfattning : The use of bone-anchored implants is today a routine treatment for patients with normal regenerative capacity. However, there is an ongoing development within implant research to improve the osseointegration of implants. LÄS MER
