TL;DR: In this paper, a good agreement between the structural transitions observed by x-ray diffraction and the vibrational modes observed in the Raman spectra is found over the whole substitutional ranges, and in particular, spectroscopic signatures of a PbZrO3-type structure for Bi0.8La0.2FeO3.

TL;DR: In this article, the authors focus on the protonicisuperprotonic electrolytes used for application in direct methanol and direct urea/urine fuel cells.

TL;DR: The crystal structure of Ca2Fe2O5 has been studied as a function of temperature up to 1000°C as discussed by the authors, and the magnetic structure was refined in space group Pcm′n′.

TL;DR: The structural behavior of caesium lead fluoride, CsPbF3, has been investigated as a function of temperature in the range 148(2)≤T (K) ≥276(2). The presence of a structural phase transition at ~190 K reported from previous nuclear magnetic resonance measurements (Bouznik V M, Moskvich Yu N and Voronov V N 1976 Chem. Phys. Lett. 37 464) has been confirmed by impedance spectroscopy and powder neutron diffraction studies as mentioned in this paper.

TL;DR: In this paper, temperature-dependent inelastic light scattering was used to study the origin of the strong multiphonon scattering of a local oxygen breathing mode present in the mixed $B$-site orthorhombic (space group $Pnma$) perovskite.
