Inhibiting octahedral tilting for stable CsPbI2Br solar cells
InfoMat, 2022 The intrinsic phase instability of CsPbI2Br perovskite hinders its development and application in solar cells. Herein, we adopt 1‐butyl‐3‐methylimidazolium hexafluorophosphate (BMIMPF6), a hydrophobic ionic liquid (IL), to improve the phase stability of ...

Synthesis and crystal structure of dipotassium nickel polyphosphate
Acta Crystallographica Section E: Crystallographic CommunicationsSingle crystals of K2Ni(PO3)4 were obtained by solid-state reaction. The structure consists of infinite zigzag polyphosphate chains, running along the c-axis direction, linked by Ni2+ ions and delimiting large tunnels in which the K+ ions are located ...

Progress in octahedral spherical hohlraum study
Matter and Radiation at Extremes, 2016 In this paper, we give a review of our theoretical and experimental progress in octahedral spherical hohlraum study. From our theoretical study, the octahedral spherical hohlraums with 6 Laser Entrance Holes (LEHs) of octahedral symmetry have robust high

Unlocking surface octahedral tilt in two-dimensional Ruddlesden-Popper perovskites
Nature Communications, 2022 The surface octahedral tilt in exfoliated 2D perovskites is directly visualized by STM and the degree of the tilt varies with the number of layers of inorganic slabs and result in different amounts of excitonic red shift in photoluminescence.

, 2018 Rotations and distortions of oxygen octahedra in perovskites play a key role in determining their functional properties. Here we investigate how octahedral rotations can couple from one material to another in La$_{2/3}$Sr$_{1/3}$MnO$_3$/SrTiO$_3 ...

Mössbauer characterisations and magnetic properties of iron cobaltites CoxFe3−xO4 (1 ≤ x ≤ 2.46) before and after spinodal decomposition [PDF]
, 2013 Iron cobaltite powders CoxFe3_xO4 (1 ≤ x ≤ 2.46) were synthesized with compositions in between the cobalt errite CoFe2 O4 and Co2.46Fe0.54O4. The cationic distribution of pure spinel phases was determined by Mossbauer spectroscopy: as Co content ...

Spatiotemporal symmetries in the disynaptic canal-neck projection [PDF]
, 2007 The vestibular system in almost all vertebrates, and in particular in humans, controls balance by employing a set of six semicircular canals, three in each inner ear, to detect angular accelerations of the head in three mutually orthogonal coordinate ...

An unexpected rhenium(IV)–rhenium(VII) salt: [Co(NH3)6]3[ReVIIO4][ReIVF6]4·6H2O
Acta Crystallographica Section E: Crystallographic Communications, 2019 The title hydrated salt, tris[hexaamminecobalt(III)] tetraoxidorhenate(VII) tetrakis[hexafluoridorhenate(IV)] hexahydrate, arose unexpectedly due to possible contamination of the K2ReF6 starting material with KReO4. It consists of octahedral [Co(NH3)6]3+
