    Sammanfattning : .... LÄS MER

  3. 2. Mesostructured materials : Synthesis towards applications

    Författare :Nina Andersson; Osamu Terasaki; Peter Alberius; Anders Palmqvist; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi; oorganisk kemi; Inorganic Chemistry;

    Sammanfattning : A new class of materials with well-defined structures on mesoscopic (2-50 nm) length scales has attracted considerable interest during the last decade. These mesostructured mataterials are formed from the self-assembly of amphiphillic molecules and inorganic precursors. LÄS MER

  4. 3. Formation mechanism of anionic-surfactant-templated mesoporous silica (AMS)

    Författare :Chuanbo Gao; Osamu Terasaki; Anders Palmqvist; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mesoporous silica; anionic surfactant; formation mechanism; structural control; Chemistry; Kemi; Structural Chemistry; strukturkemi;

    Sammanfattning : This dissertation is focused on synthesis, characterization and formation mechanism of anionic-surfactant-templated mesoporous silica (AMS). Structural control mechanisms of AMS are investigated. LÄS MER

  5. 4. The synergistic role of hierarchical macro- and mesoporous implant surface and microscopic view of enhanced osseointegration

    Författare :Guang Han; Zhijian Shen; Anders Palmqvist; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Porosity; cell adhesion; cell proliferation; surface topography; implant; bone-implant interface; argon ion beam polishing; osteogenesis; osseointegration; Materials Chemistry; materialkemi;

    Sammanfattning : The trend for designing of a titanium implant explored using different chemical compositions and crystallinity materials until people realized that the implant surface character was another important factor affecting the rate and extent of osseointegartion. Titanium received a macroporous titania surface layer by anodization, which contains open pores with average pore diameter around 5μm. LÄS MER

  7. 5. Modeling lichen performance in relation to climate : scaling from thalli to landscapes

    Författare :Anna V Jonsson Čabrajić; Kristin Palmqvist; Jon Moen; Per-Anders Esseen; Mikaell Ottosson-Löfvenius; Göran Ågren; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lichen; growth; model; micro-climate; hydration; activation; photosynthesis; respiration; Terrestrial ecology; Terrestisk ekologi; ekologisk botanik; Ecological Botany;

    Sammanfattning : Lichens can colonize nearly all terrestrial habitats on earth and are functionally important in many ecosystems. Being poikilohydric, their active growth periods are restricted to periods when the thallus is hydrated from atmospheric water sources, such as rain, fog and high relative humidity. LÄS MER
