  1. 1. LiFeSO4F as a Cathode Material for Lithium-Ion Batteries : Synthesis, Structure, and Function

    Author : Adam Sobkowiak; Fredrik Björefors; Kristina Edström; Anna Andersson; M. Rosa Palacin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Li-ion battery; cathode; LiFeSO4F; tavorite; triplite; synthesis; performance; structure; coating; PEDOT; XRD; Mössbauer spectrocopy; SEM; TEM; electrochemistry; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : In this thesis, two recently discovered polymorphs of LiFeSO4F, adopting a tavorite- and triplite-type structure, were investigated as potential candidates for use as cathode materials in Li-ion batteries. The studies aimed at enriching the fundamental understanding of the synthetic preparations, structural properties, and electrochemical functionality of these materials. READ MORE

  2. 2. Structure and stability trends in the platinum metal-silicon systems

    Author : Kenneth Göransson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Transition metal silicides; electronic band structure; monosilicides; FeSi structure type; MnP structure type; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Abstract : The stability of group 8-10 silicides has been studied by LMTO-ASA band structurecalculations. In the Rh-Si and Ir-Si systems the lowest calculated heat of formation isfound in compounds near the equiatomic composition. READ MORE

  3. 3. Sobolev-Type Spaces : Properties of Newtonian Functions Based on Quasi-Banach Function Lattices in Metric Spaces

    Author : Lukáš Malý; Anders Björn; Jana Björn; Tomas Sjödin; Andrea Cianchi; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Newtonian space; Sobolev-type space; metric measure space; upper gradient; Sobolev capacity; Banach function lattice; quasi-normed space; rearrangement-invariant space; maximal operator; Lipschitz function; regularization; weak boundedness; density of Lipschitz functions; quasi-continuity; continuity; doubling measure; Poincaré inequality;

    Abstract : This thesis consists of four papers and focuses on function spaces related to first-order analysis in abstract metric measure spaces. The classical (i.e., Sobolev) theory in Euclidean spaces makes use of summability of distributional gradients, whose definition depends on the linear structure of Rn. READ MORE

  4. 4. Structure-Magnetic Relationships in the Fe-Mn-P-Si System for Energy Applications

    Author : Viktor Höglin; Yvonne Andersson; Per Nordblad; Martin Sahlberg; Mogens Christensen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Magnetocaloric; X-ray powder diffraction; Neutron powder diffraction; Magnetization measurements; Phase diagram; Crystal structure; Magnetic structure; Incommensurate structure; Ferromagnetic; Antiferromagnetic; Fe2P; Fe-Mn-P-Si.; Kemi med inriktning mot oorganisk kemi; Chemistry with specialization in Inorganic Chemistry;

    Abstract : Demands for new, energy-efficient appliances have greatly increased in response to our growing need for a more environmentally friendly society. Magnetic refrigeration is a technique that utilizes the magnetocaloric effect, with possible energy savings of up to 30% compared to commercial gas compression refrigerators. READ MORE
