  1. 16. Photo-polymerization as a tool for engineering the active material in organic field-effect transistors

    Författare :Andrzej Dzwilewski; Ludvig Edman; Xavier Crispin; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Field-effect transistor; photo-polymerization; PCBM; C60; Fullerene; Physics; Fysik; fasta tillståndets fysik; Solid State Physics;

    Sammanfattning : The emergence of organic semiconductors is exciting since it promises to open up for straightforward and low-cost fabrication of a wide range of efficient and novel electronic devices. However, in order for this promise to become reality it is critical that new and functional fabrication techniques are developed. LÄS MER

  2. 17. Dielectric Properties of Liquid-Impregnated Porous Solids

    Författare :Bo Nettelblad; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fluid-solid interface; porous microstructure; temperature; ion-containing liquid; transport properties of porous media; brine; salinity; electric conduction; models of composite media; interface phenomena; dielectric relaxation; rock;

    Sammanfattning : Dielectric spectroscopy is a versatile tool that can often be used as a non-destructive, indirect way of measuring other important properties (such as content of crude oil or degree of curing of a resin). The dielectric properties of materials are thus of interest in several circumstances and not only for materials used for electrical purposes (such as electrical insulation). LÄS MER

  3. 18. Reactions on nanostructured and microporous surfaces

    Författare :Anna Clemens; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cu-CHA; XRD; solid-state ion-exchange; materials characterisation; electron microscopy; NH3-SCR; zeolites; catalysis; nanostructured graphite; Water ice; DRIFTS; XPS; NOx reduction; Cu-SSZ-13; temperature programmed desorption; ultra-high vacuum; intercalation; UV-Vis spectroscopy;

    Sammanfattning : Interactions between surfaces and molecules play a central role in various fields where catalysis is one example. In order to understand different surface processes, physicochemical characterisation of the surface materials and molecules is required. LÄS MER

  4. 19. Experimental data and Total Monte Carlo : Towards justified, transparent and complete nuclear data uncertainties

    Författare :Petter Helgesson; Henrik Sjöstrand; Arjan Koning; Stephan Pomp; Dimitri Rochman; Klaes-Håkan Bejmer; Denise Neudecker; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Sammanfattning : The applications of nuclear physics are many with one important being nuclear power, which can help decelerating the climate change. In any of these applications, so-called nuclear data (ND, numerical representations of nuclear physics) is used in computations and simulations which are necessary for, e.g., design and maintenance.

  5. 20. From Metric to Connection. Actions for Gravity, with Generalizations

    Författare :Peter Peldan; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The search for a theory of quantum gravity has for a long time been almost fruitless. A few years ago, however, Ashtekar found a reformulation of Hamiltonian gravity, which thereafter has given rise to a new promising quantization project; the canonical Dirac quantization of Einstein gravity in terms of Ashtekar's new variables.
