  2. 1. Solid-State NMR Characterization of Lipid Membranes

    Author : Vasco Castro; Arnold Maliniak; Göran Lindblom; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Solid-State NMR; Membranes; Lipids; Glycolipids; Local Anesthetics; Hydration; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Abstract : This thesis deals with the study of lipid bilayer systems by solid-state nuclear magnetic resonance. Two-dimensional 1H-13C separated local field experiments under magic-angle spinning were employed to investigate structural and dynamical modifications of cell membranes, resulting from the addition of compounds with some biological relevance.

  4. 2. Quantum State Analysis : Probability theory as logic in Quantum mechanics

    Author : Anders Månsson; Anders Karlsson; Gunnar Björk; Ingemar Bengtsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; quantum; quantum mechanics; state; state analysis; probability; probability theory; logic; Photonics; Fotonik;

    Abstract : Quantum mechanics is basically a mathematical recipe on how to construct physical models. Historically its origin and main domain of application has been in the microscopic regime, although it strictly seen constitutes a general mathematical framework not limited to this regime.

    Abstract : Hydrogen fuel cells represent one of the most promising sustainable technologies for energy conversion. The advantages of the combination of a solid state electrolyteand low operational temperatures (... READ MORE

  6. 4. Dynamic Structure Discovery and Ion Transport in Liquid Battery Electrolytes

    Author : Rasmus Andersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ion transport mechanisms; electrolytes; dynamic structure discovery; lithium-ion batteries; statistical physics;

    Abstract : The lithium-ion battery (LIB), the realisation of which earned the Nobel Prize in Chemistry 2019, has since its 1991 commercialisation become the dominant energy storage technology first for cell phones and other mobile electronics, then for power tools and other domestic appliances, and currently for electric cars and other vehicles. However, many applications would still benefit from higher power and energy densities, longer life-lengths and safer batteries. READ MORE

  7. 5. Atom Probe Tomography of Hydrogen and of Grain Boundaries in Corroded Zircaloy-2

    Author : Gustav Sundell; Chalmers tekniska högskola; []

    Abstract : Due to their low thermal neutron capture cross-section, zirconium alloys are widely used in the nuclear industry for fuel cladding and structural components. The lifetime of the fuel assemblies in the reactors are largely dictated by the ability of the fuel cladding to withstand corrosion and mechanical damage. READ MORE
