  4. 2. Single-crystal Mo/V superlattices : growth, structure, and hydrogen uptake

    Author : Jens Birch; Jan-Erik Sundgren; Bruce M Clemens; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Fundamental studies concerning the growth, structural characterization and hydrogen uptake of single-crystal (00 l )-oriented Mo/V superlattices have been performed. The superlattices were grown by dual-target magnetron sputtering in pure Ar-atmosphere < 6·10-3 Torr on (001)-oriented MgO substrates. READ MORE

  5. 3. Cooperative Lithium-Ion Insertion Mechanisms in Cathode Materials for Battery Applications

    Author : Helen Björk; Tsutomo Ohzuku; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Li-ion battery; cathode materials; single-crystal; X-ray diffraction; delithiation; superlattice; phase transformation; charge-ordering; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Abstract : Understanding lithium-ion insertion/extraction mechanisms in battery electrode materials is of crucial importance in developing new materials with better cycling performance. In this thesis, these mechanisms are probed for two different potential cathode materials by a combination of electrochemical and single-crystal X-ray diffraction studies. READ MORE

  6. 4. Solving Mysteries and Outwitting Transitions : Investigating the Incommensurate Crystal Structures of AuIn and Sn3Sb2

    Author : Laura Folkers; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Crystallography; Modulation; Intermetallics; X-Ray Diffraction; Single crystal;

    Abstract : This thesis introduces two new incommensurate alloys. AuIn shows variable amounts of modulation, depending on the measurement temperature. At 400°C the diffraction pattern shows diffuse scattering and a thallium iodide type Cmcm space group. READ MORE

  7. 5. Using Light to Probe Surface Electrochemical Processes

    Author : Weronica Linpe; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electrochemistry; X-ray methods; In situ; synchrotron radiation; Ex situ; Single crystal; polycrystalline; aluminium oxide; Au; Pd; Pt; Sn; Super duplex stainless steel.; Fysicumarkivet A:2021:Linpé;

    Abstract : This thesis shows how various light-based in situ techniques can be used to follow different surface electrochemical processes such as electrochemical deposition into Nanoporous Anodic Aluminium Oxide (NP-AAO) templates and the surface structure of electrodes. Techniques based on both x-rays and visible light were used to follow surface structures and compositions, in situ. READ MORE
