Crystal structure and phonon softening in Ca3Ir4Sn13

, 2015
We investigated the crystal structure and lattice excitations of the ternary intermetallic stannide Ca3Ir4Sn13 using neutron and x-ray scattering techniques. For T > T* ~ 38 K the x-ray diffraction data can be satisfactorily refined using the space group

Effect of Deformation Mechanisms on Magnetic Record in Marble Shear Zones

Geochemistry, Geophysics, Geosystems
Processes that form and deform any rock leave distinct imprints on its microstructure. The description and interpretation of these microstructural features aids in understanding rock's evolution.

Understanding and Optimizing Li Substitution in P2‐Type Sodium Layered Oxides for Sodium‐Ion Batteries

Advanced Functional Materials, EarlyView.
This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous
