Summary: The study reports the design, synthesis, structure, and properties of two complex layered phosphide nitrides, highlighting the significant antiferromagnetic interactions and strong electron correlations present in the compounds.
Properties such as interlayer charge transfer and built-in chemical pressure from specific layers have effects on the lattice and atomic positions of phosphorus in the compounds.
There are both local moments and itinerant electrons present in the compounds, with dominant antiferromagnetic interactions shown in first-principles calculations when additional Coulomb repulsions are considered.

Summary: Deracemization, the process of converting a racemate into a single enantiomer without separating the intermediate, has regained attention in asymmetric synthesis due to its atomic economy and high efficiency. However, this process requires selective energy input and careful reaction design to overcome thermodynamic and kinetic constraints. With the development of asymmetric catalysis, catalytic strategies combined with exogenous energy input have been explored to enhance nonspontaneous enantioenrichment.

Summary: The study focused on the changes in electrical and structural parameters of nontronite with temperature variations from 25 degrees C to 325 degrees C. Heating causes nontronite to lose water from the interlayer space, leading to significant structural alterations. The experiments showed that the mineral loses only a small part of water between the layers at 35-60 degrees C, resulting in changes in interlayer distance and electric permittivity. The main process of losing interlayer water molecules starts at 60 degrees C and finishes close to 160 degrees C.

Summary: In this study, a catalytic version of the Vilsmeier-Haack reaction enabled by a P(III)/P(V)=O cycle was reported. The reaction provides a convenient and efficient route for the direct construction of C1-deuterated indol-3-carboxaldehyde under mild conditions. The products have a high deuteration level and are not affected by non-selective deuteration. Furthermore, this transformation can be used to transfer other carbonyl groups.

Summary: In this study, intergrowth of multiferroic compounds Bi4RTi3Fe0.7Co0.3O15-Bi3RTi2Fe0.7Co0.3O12-delta (BRTFCO15-BRTFCO12) (rare earth (R) = Dy, Sm, La) were prepared using solid-state reaction method. The X-ray diffraction Rietveld refinement revealed orthorhombic structure with three-layered and four-layered compounds. Magnetic measurements showed that the Sm-modified intergrowth compound had a larger magnetization compared to Dy- and La-doped ones. The higher magnetization can be attributed to distortion in the unit cell, bonding of Fe3+-O-Co3+, and possible mixture of FexCoy-type nanoparticles formed during synthesis of intergrowths. The results demonstrate that the RE-modified intergrowth method is an effective approach for preparing higher-layer Aurivillius multiferroic ceramics.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
