  1. 21. Structure, Dynamics and Thermodynamics of Liquid Water : Insights from Molecular Simulations

    Författare :Kjartan Thor Wikfeldt; Lars G. M. Pettersson; Francesco Sciortino; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Liquid water; supercooled water; diffraction; structure modeling; molecular dynamics; x-ray spectroscopy; EXAFS; SAXS; Physics; Fysik; Theoretical Physics; teoretisk fysik;

    Sammanfattning : Water is a complex liquid with many unusual properties. Our understanding of its physical, chemical and biological properties is greatly advanced after a century of dedicated research but there are still many unresolved questions. LÄS MER

  3. 22. Direct conversion of methane-to-methanol in Cu-exchanged small-pore zeolites

    Författare :Unni Engedahl; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; partial methane oxidation; SSZ-13; density functional theory; catalysis; micro-kinetic modeling; zeolites; CHA; copper;

    Sammanfattning : Fossil fuel consumption continuous to increase worldwide and of all the fossil fuels, natural gas is growing the most. The combustion of natural gas, which mainly contains methane, is more environmentally friendly than oil or coal thanks to its high specific energy. LÄS MER

  4. 23. Nanostructured carbon materials under extreme conditions

    Författare :Mattias Mases; Fernando Rodríguez; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Experimentell fysik; Experimental Physics;

    Sammanfattning : The discovery of the Buckminsterfullerene in 1985 by Richard Smalley, Robert Curl and Harold Kroto opened an era of great interest to the exploration of nanostructured carbon materials. These materials come in many forms and are often categorized by their dimensionality. Graphene is an ideal 2-dimensional (2D) sheet of sp2-bonded carbon atoms. LÄS MER

  5. 24. Physical Properties of Ternary Metal Oxides and Carbon Nanomaterials Under Pressure

    Författare :Pablo Botella; Alberto Vomiero; Daniel Errandonea; Victor Lavin Della Ventura; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Experimentell fysik; Experimental Physics;

    Sammanfattning : Found in nature or synthesized, materials present amazing properties such as superconductivity, super-hardness, lightweight, or high-energy-density, among others. All these properties can be used in our benefit to improve or develop new applications. LÄS MER

  7. 25. Physical properties and structural stability of carbon nanotubes under extreme conditions

    Författare :Maxime Noël; David Dunstan; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Experimentell fysik; Experimental Physics;

    Sammanfattning : Carbon nanotubes (CNTs) have attracted an immense attention of the research community since reporting on this system by S. Ijima in 1991. A "single-walled" CNT (SWCNT) can be considered as a rolled-up single-layer graphene - a one atom-thick layer of carbon atoms arranged in a hexagonal lattice. LÄS MER
