  2. 1. Shaping Macroporous Ceramics : templated synthesis, X-ray tomography and permeability

    Author : Linnéa Andersson; Lennart Bergström; Ludwig Gauckler; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Alumina; ceramic; CO2 capture; colloidal processing; expandable microspheres; gel casting; layer-by-layer; macroporosity; near-net shape; non-destructive evaluation; permeability; porosity; sacrificial templating; X-ray computed tomography; Chemistry; Kemi; Materials Chemistry; materialkemi;

    Abstract : Macroporous ceramic materials have found widespread technological application ranging from particulate filters in diesel engines, tissue engineering scaffolds, and as support materials in carbon capture processes. This thesis demonstrates how the pore space of macroporous alumina can be manipulated, analysed in three-dimensions (3D) using visualisation techniques, and functionalised with a CO2-adsorbing material.

  4. 2. Exploring expandable microspheres as a novel pore former in gel-cast macroporous alumina

    Author : Linnéa Andersson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gel casting; macroporosity; Al2O3; near-net shape; expandable microspheres; layer-by-layer adsorption; polyelectrolyte; multilayer; colloids; X-ray micro-computed tomography; Lab CT; Organic chemistry; Organisk kemi;

    Abstract : Expandable microspheres have been explored as sacrificial templates for the production of macroporous ceramics. Concentrated alumina powder suspensions that contain expandable microspheres have been consolidated by gel-casting. READ MORE

  5. 3. Removal of endocrine-disrupting compounds from wastewater using molecular imprinting

    Author : Mathieu Le Noir; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; molecular imprinting; Endocrine-disrupting compounds; wastewater; macroporous gel; trace contaminants;

    Abstract : Endocrine-disrupting compounds (EDCs) such as hormones and certain pharmaceuticals (i.e. birth control pills, oestrogen replacement products and other steroids) can interfere with the regulatory systems of humans and wildlife. Many of these compounds are excreted by humans and released with sewage. READ MORE

  6. 4. Preparation and Characterization of Macroporous Cryostructured Materials

    Author : Harald Kirsebom; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Macroporous hydrogels are regarded as interesting materials both within biotechnology and biomedicine due to their properties. These materials can be prepared from a wide range of synthetic or naturally occurring compounds using a number of different techniques for their production. READ MORE

  7. 5. Templating and self-assembly of biomimetic materials

    Author : Christian Mille; Lennart Bergström; Mika Linden; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biomimetic; biotemplating; self-assembly; triply periodic minimal surfaces; the gyroid; photonic crystals; band gap; structural color; chirality; butterflies; membrane proteins; lipid bilayers; sol-gel; mesostructured; polyhedral nanofoams; Materials Chemistry; materialkemi;

    Abstract : This thesis focuses on the use of biomolecular assemblies for creating materials with novel properties. Several aspects of biomimetic materials have been investigated, from fundamental studies on membrane shaping molecules to the integration of biomolecules with inorganic materials. READ MORE
