    Synthesis of metal nanomaterials with unconventional crystal phases and their applications in electrocatalysis by Liu, Jiawei

    Published 2021
    “…On the other hand, phase-controlled synthesis of bimetallic Pd3Sn nanorods, including the ordered L12 phase and the disordered fcc phase, is achieved via wet-chemical methods. Experimentally, the usage of different types of tin precursors and solvents is decisive for controlling their crystal phases. …”

    A signal through the noise: accurate determination of hydrogen atom positions in crystal structures and optimisation of Laue neutron diffraction methods by Sackman, GA

    Published 2021
    “…This has allowed a variety of chemically and crystallographically interesting studies to be performed, specifically:</p> <p>Determining the novel geometry around transition-metal hydride centers, where the signal due to the hydrides can be more confidently distinguished than in an X-ray diffraction experiment; using Laue neutron derived difference Fourier maps to demonstrate that proton disorder can be mistakenly assigned in X-ray derived crystallographic models; performing variable temperature Laue neutron diffraction to identify proton migratory behaviour across short-strong hydrogen bonds; reassigning the space group of a previously reported cobalt(III) coordination complex, in which the lack of inversion symmetry becomes apparent upon accurate determination of the hydrogen atom positions; using Laue neutron diffraction data to more confidently classify systems as co-crystals or salts.…”

    High-spin impurities and surface acoustic waves in piezoelectric crystals for spin-lattice coupling by Magnusson, E

    Published 2016
    “…We concluded it to be a transition induced by acoustic coupling since the signal intensity did not tend to zero when the magnetic field was parallel to the crystal anisotropy axis. Furthermore, this tells us that the coupling is due to a modulation of the E zero-field splitting parameter rather than <em>D</em>. …”
