  2. 1. Quantum Nuclear Dynamics in Resonant X-ray Scattering of Gas-Phase and Liquid Systems

    Author : Vinicius Vaz da Cruz; Victor Kimberg; Faris Gel'mukhanov; Hans Ågren; Philippe Wernet; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; resonant inelastic X-ray scattering; X-ray absorption; water; methanol; CO; rotational doppler effect; recoil; wave packet; non-Franck-Condon effect; ultra-fast molecular dissociation; potential energy surface; hydrogen bond; liquid; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Abstract : This thesis focuses on the role of the nuclear degrees of freedom in X-ray induced molecular processes. An important part of it is devoted to establishing theoretical principles to model and interpret high-resolution resonant X-ray scattering experiments in gases and liquids. READ MORE

  4. 2. Development of a methanol reformer for fuel cell vehicles

    Author : Bård Lindström; KTH; []
    Keywords : methanol; fuel cell vehicles; reforming; catalysis; partial oxidation; steam reforming; combined reforming;

    Abstract : Vehicles powered by fuel cells are from an environmentalaspect superior to the traditional automobile using internalcombustion of gasoline. Power systems which are based upon fuelcell technology require hydrogen for operation. The ideal fuelcell vehicle would operate on pure hydrogen stored on-board. READ MORE

    Abstract : In this work, the solubility of butyl paraben in 7 pure solvents and in 5 different ethanol-water mixtures has been determined from 1 ˚C to 50 ˚C. The solubility of ethyl paraben and propyl paraben in various solvents has been determined at 10 ˚C. READ MORE

  6. 4. Devlopment and relaxation of orientation in liquid crystalline polymers : transport properties of liquid crystalline polymer blends

    Author : Göran Wiberg; KTH; []
    Keywords : ;

    Abstract : In this thesis different types of liquid crystallinepolymers have been investigated with respect to build up andrelaxation of orientation. The potential of making new barriermaterials using liquid crystalline polymer blends was alsostudied. READ MORE

  7. 5. Liquid-Jet-Target Microfocus X-Ray Sources : Electron Guns, Optics and Phase-Contrast Imaging

    Author : Tomi Tuohimaa; Hans M. Hertz; Stephen Wilkins; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electron-impact; x-ray; brightness; liquid-jet-target; phase-contrast imaging; Engineering physics; Teknisk fysik;

    Abstract : This Thesis describes the development of an electron-impact microfocus x-ray source and its application for phase-contrast imaging. The source is based on a novel, liquid-jet target concept. Stable and continuous operation can be achieved at substantially higher electron-beam power densities than conventional solid target based systems. READ MORE
