  1. 1. Multiscale Modeling of Interfaces

    Författare :Sven Johansson; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; misfit; Peierls-Nabarro model; semicoherent interfaces; interfaces; cemented carbides; grain boundaries; microstructure; VN precipitates; density-functional theory;

    Sammanfattning : Understanding strength and stability of interfaces between dissimilar materials or phases is a highly active field of contemporary materials research. Knowledge of interface structure and energetics is important for modeling of complex materials both on a mechanical and thermodynamical level as well as for many functional properties. LÄS MER

  2. 2. Phthalocyanine interfaces the monolayer region

    Detta är en avhandling från Stockholm : KTH

    Författare :Pål Palmgren; Mats Göthelid; Mats Fahlman; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phthalocyanine; III-V semiconductor; transition metal oxides; adsorption; self-assembly; TECHNOLOGY Engineering physics Material physics with surface physics; TEKNIKVETENSKAP Teknisk fysik Materialfysik med ytfysik;

    Sammanfattning : Organic molecules adsorbed on inorganic substrates are the topics of interest in this thesis. Interfaces of this kind are found in dye sensitized solar cells that convert solar energy to electricity, a promising environmentally friendly energy source which might provide a route to replace fossil fuels.

  3. 3. Organoleptic Interfaces: Exploring Embodied Methods in Foodscapes

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Anna Maria Orru; Göteborgs universitet.; Gothenburg University.; [2016]
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; urban-making; embodiment; artistic-based research; foodscapes; relational assemblages; deeper commitment to environment; performativity; imagineering; critical cartography; choreography; performativity; imagineering; critical cartography; relational assemblages; deeper commitment to environment; embodiment; foodscapes; choreography; artistic-based research;

    Sammanfattning : In the move to re-acquaint urban green and in-between spaces as solely parks and open spaces, this research looks to the concept of emerging foodscapes to form a transformative behaviour with food in the city. Urban population growth, unstable food security, environmental consequences of industrial food production are all motives for concern, alongside individual awareness of food provisioning, seasonal availability and behaviour.

  4. 4. Mass-Transport through Interfaces

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Sofie Gårdebjer; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; poly 3-hydroxybutyrate ; permeability; diffusion cells; poly lactide-co-glycolide acid ; mass-transport; polyethylene; poly lactic acid ; ethylene acrylic acid; interfaces; cellulose;

    Sammanfattning : Many of the products in our daily life consist of layered structures, where packaging materials and wound care products can be mentioned as examples. These structures often consist of different kind of polymeric materials and between these materials interfaces are formed. LÄS MER

  5. 5. The Multiple Faces of Interfaces Electron microscopy analysis of CuInSe2 thin-film solar cells
