A structural study of Sm- and Gd-doped ceria was performed with the aim to clarify some unexplained features. (Ce1-xREx)O2-x/2 samples (RE ≡ Sm, Gd; x = 0, 0.1, ..., 1) were prepared by coprecipitation mixed oxalates subsequent thermal treatment at 1473, 1173, or 1073 K in air; they then analyzed room temperature both synchrotron X-ray diffraction μ-Raman spectroscopy. Two models adopted fit experimental data, namely, a fluoritic one, resembling CeO2 structure low RE content, hybrid one...
Temperature dependent single-crystal x-ray diffraction (XRD) in transmission mode probing the bulk of newly discovered K0.8Fe1.6Se2 superconductor (Tc = 31.8 K) using synchrotron radiation is reported. A clear evidence intrinsic phase separation at 520 K between two competing phases, (i) a first majority magnetic with ThCr2Si2-type tetragonal lattice modulated by iron vacancy ordering and (ii) minority non-magnetic having an in-plane compressed volume weak superstructure, The XRD peaks due...

Abstract The rapid progress in mass-market applications of metal-ion batteries intensifies the development economically feasible electrode materials based on earth-abundant elements. Here, we report a record-breaking titanium-based positive material, KTiPO 4 F, exhibiting superior potential 3.6 V potassium-ion cell, which is extraordinarily high for titanium redox transitions. We hypothesize that such an unexpectedly major boost benefits from synergy cumulative inductive effect two anions...
Since their first appearance, organic-inorganic perovskite absorbers have been capturing the attention of scientific community. While high efficiency devices highlight importance band level alignment, very little is known on origin strong n-doping character observed in perovskite. Here, by means a highly accurate photoemission study, we shed light energy alignment perovskite-based devices. Our results suggest that interaction with substrate may be driver for doping samples.
A room temperature structural study has been performed through the whole compositional range of (Ce1–xLux)O2–x/2 system by synchrotron X-ray diffraction and μ-Raman spectroscopy. Samples were synthesized thermal treatment in air at 1373 K coprecipitated mixed oxalates. CeO2-based solid solution with a fluorite-type structure (F) was found to be stable up x = 0.4, while higher Lu content (F + C) biphasic region observed, C being cubic atomic arrangement typical sesquioxides heaviest rare...
Manganese hexacyanoferrates (MnHCF) are promising positive electrode materials for non-aqueous batteries, including Na-ion due to their large specific capacity (>130 mAh g-1 ), high discharge potential and sustainability. Typically, the electrochemical reaction of MnHCF associates with phase structural changes, Jahn-Teller (JT) distortion Mn sites upon charge process. To understand effect structure on its performance, two different vacancies content investigated herein. The results show that...

Manganese hexacyanoferrate (MnHCF) has received increasing attention as a positive electrode for either lithium- or sodium-ion storage owing to its high specific capacity among the Prussian blue analogues (PBAs). During ion release, material undergoes Jahn–Teller distortion arising from oxidation of manganese trivalent state. Typically, is reported destabilize host structure materials based on layered and spinel oxides, resulting in volume changes order 10–20%, which deteriorate cycle...
