A nonlinear peek into electronic symmetry Strong interactions among electrons in some materials can cause them to assume configurations that are less symmetric than the underlying crystal lattice. These so-called nematic states usually have inversion symmetry, but theorists predicted metals with strong spin-orbit coupling, be lost. Harter et al. teased out of order compound Cd 2 Re O 7 (see Perspective by Dodge). They found a known structural transition this material is consequence another,...
The fabrication of formamidinium lead iodide (FAPbI3) perovskite solar cells (PSCs) involves the addition methylammonium chloride (MACl) to promote low-temperature α-phase formation and grain growth. However, as added MACl deprotonates volatilizes into methylamine (MA0) HCl for removal, MA0 can chemically interact with (FA+), forming methyl (MFA+) a byproduct. Despite its significance, chemical interactions among FAPbI3 perovskites, additives, their byproducts remain poorly understood. Our...
The rich physics manifested by 5d oxides falls outside the Mott-Hubbard paradigm used to successfully explain electronic and magnetic properties of 3d oxides. Much consideration has been given extent which strong spin-orbit coupling (SOC), in limit increased bandwidth reduced electron correlation, drives formation novel states, as through existence metal-insulator transitions (MITs). SOC is believed play a dominant role 5d5 systems such iridates (Ir4+), undergoing MITs may or not be...
Hydrogenation of carbon dioxide (CO2) to methane (CH4) bears the potential not only alleviate excessive emission CO2 but produce clean energy for direct use. However, due high temperature required activation CO2, it is necessary develop a catalyst with activity and CH4 selectivity at low reaction methanation. In this study, we synthesized titanium (TiO2) supports different rutile contents by calcination investigated relationship between content TiO2 in Ru/TiO2 catalysts their performance...
High quality single crystals of BaFe$_{12}$O$_{19}$ were grown using the floating zone technique in flowing oxygen pressurized to 100 atm. Single crystal neutron diffraction was used determine nuclear and magnetic structure at 4 K 295 K. At both temperatures, there exist local electric dipoles formed by off-mirror-plane displacements Fe$^{3+}$ ions bipyramidal sites. The displacement is about half that room temperature. temperature dependence specific heat shows no anomaly associated with...
Abstract Enhanced coupling of material properties offers new fundamental insights and routes to multifunctional devices. In this context 5 d oxides provide paradigms cooperative interactions that drive novel emergent behaviour. This is exemplified in osmates host metal–insulator transitions where magnetic order appears intimately entwined. Here we consider such a material, the perovskite NaOsO 3 , observe between spin phonon manifested frequency shift 40 cm −1 largest measured any material....

ABSTRACT The protection of steel based on microbial biomineralization has emerged as a novel and eco-friendly strategy for corrosion control. However, the molecular basis process in mineralization bacteria remains largely unexplored. We previously reported that Pseudoalteromonas lipolytica EPS+ strain provides against by forming hybrid film. In this study, we identified point mutation AT00_08765 ( wspF- like) gene, responsible encoding chemotaxis protein regulates swimming motility...
Two new compounds ACo 5 (SeO 3 ) 4 (OH) 2 F (A = Rb, Cs) were synthesized by introducing − , exhibiting a distorted 2-uniform T29 lattice.
We prepared four isomeric phases of CdVO(SeO3)2, α-, β-, γ-, and δ-phases by hydrothermal reactions characterized their structural, thermal, magnetic properties. These compounds all exhibit one-dimensional (1D) chains made up distorted VO5 square pyramids such that the apical oxygen Oap each pyramid acts as sixth ligand to an adjacent form (V–Oap···V–Oap···)∞ chains. The Se4+ ions (SeO3)2– anions bridge basal atoms Obs V–Obs···Se4+·· Obs–V spin exchange paths within chain in γ- δ-phases, but...
A series of transition metal sulfate compounds, M7(SO4)3(OH)8 (M = Co, Ni, Cu), have been hydrothermally synthesized and exhibit unique topological spin lattices composed mixed kagomé triangular motifs. Co7(SO4)3(OH)8 Ni7(SO4)3(OH)8 feature alternating layers along the c-axis, while Cu7(SO4)3(OH)8 shows merged motifs extending a-axis due to greater octahedral distortion. Magnetic measurements reveal that exhibits a ferrimagnetic at ∼6.5 K with strong frustration, undergoes long-range...

The catalytic activation of CO2 is a crucial process in recycling for both fundamental research and industrial applications. Fe-based catalysts have been demonstrated to be highly active the reverse water gas shift (RWGS) reaction. However, structural complexity dynamic reduction/oxidation/carburization iron-based mean that it challenging understand mechanism these further improve their reaction activity. Herein, we report efficient Pt/Fe3O4 catalyst RWGS reaction, which content Pt only...
