TL;DR: It is shown that iodide ions in the methylammonium lead iodide migrate via interstitial sites at temperatures above 280 K, which coincides with temperature dependent static distortions resulting in pseudocubic local symmetry.

TL;DR: In this paper, the authors report the development of MgAl2O4-stabilized, Cu-modified, Fe2O3-based redox materials for thermochemical water splitting that show a high reactivity towards CH4 and low rates of carbon deposition.

TL;DR: In this article, the authors apply neutron spectroscopy to show that the same acoustic phonon energy linewidth broadening (corresponding to shortened lifetimes) occurs in the fully inorganic lead halide perovskites.

TL;DR: A Na(+) doping strategy to phase stabilize Al2O3-supported CuO is reported, yielding in turn an inexpensive material with a high redox stability and CO2 capture efficiency and conclusively the improved redox characteristics of the new oxygen carriers developed.

TL;DR: This study provides evidence for ascribing the linear increase in ADPs as well as the expansion of the c axis to the accumulation of foreign species in the crystal, and not to a thermal effect.
