  2. 1. The effect of nano-confinement on hydrogen uptake in metallic superlattices

    Author : Sotirios A. Droulias; Max Wolff; Gunnar K. Pálsson; Björgvin Hjörvarsson; Daniel Azofeifa; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The absorption of hydrogen is exothermic in vanadium whereas it is endothermic in iron and chromium. Investigations of the hydrogen uptake within Fe/V(001) and Cr/V(001) superlattices allow therefore a detailed exploration of finite size effects and the influence of boundaries on hydrogen absorption.

  4. 2. Synthesis and characterization of Ga-containing MAX phase thin films

    Author : Andrejs Petruhins; Johanna Rosén; Per O A Persson; Erik Lewin; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The study of magnetic Mn+1AXn (MAX) phases (n = 1 − 3, M – a transition metal, A – an A group element, X – C or N) is a recently established research area, fuelled by theoretical predictions and first confirmed experimentally through alloying of Mn into the well-known Cr2AlC and Cr2GeC. Theoretical phase stability investigations suggested a new magnetic MAX phase, Mn2GaC, containing Ga which is liquid close to room temperature. READ MORE

  5. 3. Carbide and MAX-Phase Engineering by Thin Film Synthesis

    Author : Jens-Petter Palmquist; Ulf Jansson; M. Jochen Schneider; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Thin films; microstructure; epitaxy; carbide; WC; MAX-phase; Ti3SiC2; DC magnetron sputtering; PVD; Reciprocal Space Mapping; RSM; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi;

    Abstract : This thesis reports on the development of low-temperature processes for transition metal carbide and MAX-phase thin film growth. Magnetron sputtering and evaporation, far from thermodynamical equilibrium, have been utilised to engineer the properties of the films by physical and chemical control. READ MORE

  6. 4. Coherent Diffractive Imaging with X-ray Lasers

    Author : Max Felix Hantke; Filipe R. N. C. Maia; Janos Hajdu; Martin Svenda; Edgar Weckert; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; coherent diffractive X-ray imaging; lensless imaging; coherent X-ray diffractive imaging; flash diffractive imaging; single particle imaging; aerosol injection; electrospray injection; substrate-free sample delivery; carboxysome; phase retrieval; X-ray diffraction software; X-ray free-electron laser; XFEL; FEL; CXI; CDI; CXDI; FXI;

    Abstract : The newly emerging technology of X-ray free-electron lasers (XFELs) has the potential to revolutionise molecular imaging. XFELs generate very intense X-ray pulses and predictions suggest that they may be used for structure determination to atomic resolution even for single molecules. READ MORE

  7. 5. Self-assembly of magnetic particles

    Author : Hauke Carstensen; Max Wolff; Vassilios Kapaklis; Björgvin Hjörvarsson; Benjamin Yellen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; self-assembly; tunable interactions; phase transition; ferrofluid; Fysik; Physics;

    Abstract : Self-assembly is the spontaneous formation of larger structures from small building blocks. This process is driven and determined by the interactions between the constituents. READ MORE
