Autor: Andrew Robert Drews, Tyler H. Bennett, Melanie J. Kirkham, Robert L. Sacci, Jagjit Nanda, Venkataramani Anandan, Luke L. Daemen

Publikováno v: Journal of Materials Chemistry A. 9:990-996

Select rare-earth alkali halides have demonstrated high lithium ion conductivity. The conductivity appears to be related to the stability of the crystal phase, ordering of the lithium sublattice and the amount of residual H2O. Li3InCl6 can be synthes

Metastable Li1+δMn2O4 (0 ≤ δ ≤ 1) Spinel Phases Revealed by in Operando Neutron Diffraction and First-Principles Calculations

Autor: Jinseon Park, Gabriel M. Veith, Jue Liu, Melanie J. Kirkham, Pamela S. Whitfield, Ashfia Huq, Mina Yoon, Bohang Song

Publikováno v: Chemistry of Materials. 31:124-134

In this work, we examine the reaction mechanisms driven by the lithiation of Li1+δMn2O4 (0 ≤ δ ≤ 1) spinels via in operando neutron powder diffraction (NPD). New reaction mechanisms are proposed involving solid-solution regions within both cubi

Temperature-dependent Structural and Spectroscopic Studies of (Bi1–xFex)FeO3

Autor: M. Mangir Murshed, F. Jochen Litterst, Thorsten M. Gesing, Andrea Kirsch, Melanie J. Kirkham, Ashfia Huq

Publikováno v: The Journal of Physical Chemistry C. 122:28280-28291

We report on temperature-dependent structural and spectroscopic features of (Bi1–xFex)FeO3 perovskite for x = 0.15 and 0.25. Samples were synthesized by heating quantum crystalline precursors obtai...

Determination of Bulk and Surface Atomic Arrangement in Ni–Zn γ-Brass Phase at Different Ni to Zn Ratios

Autor: Anish Dasgupta, Melanie J. Kirkham, Robert M. Rioux, Gaurav Kumar, Charles S. Spanjers, Michael J. Janik, Blake Burger

Publikováno v: Chemistry of Materials. 29:504-512

Previous attempts to characterize the γ-brass crystal structure of Ni–Zn (15.4–24% Ni) have failed to identify the location of the Ni and Zn atoms in the crystal lattice for more than 15.4% Ni content (Ni8Zn44) due to the similar X-ray diffracti

The Debye-Waller factors of refractory bcc solid-solution alloys TiVNbTa and TiVNbMoTa measured by low temperature neutron diffraction are obviously larger than that of the face-centered cubic (fcc) solid-solution alloy NiCoFeCrMn. The bcc lattice of
