  1. 1. Characterization of Micro-Structures in Materials

    Detta är en avhandling från Göteborg : Chalmers University of Technology and University of Gothenburg

    Författare :Henrike Häbel; Göteborgs universitet.; Gothenburg University.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Clustering; colloidal nanoparticle gels; image analysis; mass transport; point pattern; polymer blended films; pore shape; pore shape; image analysis; mass transport; point pattern; polymer blended films; colloidal nanoparticle gels;

    Sammanfattning : On developing the next generation sustainable soft materials, it is often crucial to understand and control their properties and function. Whereas a characterization of three-dimensional data is desirable in corresponding studies, often two-dimensional data are less time consuming to obtain. LÄS MER

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

    Sammanfattning : 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. LÄS MER

  3. 3. Membrane emulsification: modelling interfacial and geometric effects on droplet size

    Detta är en avhandling från Food Technology, Lund University

    Författare :Marilyn Rayner; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pore geometry; membrane emulsification; Gases; Surface Evolver; fluid dynamics; plasmas; Gaser; fluiddynamik; plasma; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Food and drink technology; modelling; Livsmedelsteknik;

    Sammanfattning : Emulsification is an important unit operation used in the pharmaceutical, food, and cosmetic industry. Membrane emulsification is a relatively new membrane technology which allows the production of emulsion droplets under controlled conditions with a narrow droplet size distribution. LÄS MER

  4. 4. Molecular and ultrastructural analysis of Tpr, a nuclear pore complex-attached coiled-coil protein

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Cell and Molecular Biology

    Författare :Manuela Hase; Karolinska Institutet.; Karolinska Institutet.; [2003]

    Sammanfattning : Anchored in the nuclear envelope, nuclear pore complexes (NPCs) are large multiprotein complexes which serve as the gateway for nucleocytoplasmic transport. In vertebrates, a 267kDa protein termed Tpr has been localized to the nucleoplasmic side of the NPCs. The function of Tpr has remained largely elusive. LÄS MER

  5. 5. Shaping Macroporous Ceramics templated synthesis, X-ray tomography and permeability

    Detta är en avhandling från Stockholm : Department of Materials and Environmental Chemistry, Stockholm University

    Författare :Linnéa Andersson; Lennart Bergström; Ludwig Gauckler; [2011]
    Nyckelord :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; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi; materialkemi; Materials Chemistry;

    Sammanfattning : 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.
