Summary: This article describes a heavily shocked and melted Suizhou meteorite that contains a minor amount of diopside. A shock-metamorphosed diopside grain associated with ringwoodite and lingunite was found inside a melt vein of this meteorite. Through various analyses, four silicate phases named A, B, C, and D were identified in this shock-metamorphosed diopside grain. Based on high-pressure and high-temperature experiments, it was determined that the diopside grain in the Suizhou meteorite experienced a P-T regime of 20-24 GPa and 1800 - > 2000 degrees C. The orthorhombic (Ca0.663Mg0.314)SiO3 perovskite found in the Suizhou L6 chondrite could be considered as the third lower-mantle silicate mineral.

Summary: Amino-MIL-101(Fe) was synthesized and tested for post-combustion CO2 capture, with a hybrid model providing better agreement with experimental data. The adsorption process of CO2 and N2 at low pressure was found to not be kinetically controlled. The adsorption selectivity of CO2 over N2 was estimated to be 1.6 using IAST.

Summary: This letter investigates the joining of immiscible pure iron and pure magnesium using solid metal deal-loying. The Fe-Mg bicontinuous composite was formed at the weld interface by diffusion bonding and SMD. The Ni composition in the interlayer greatly influenced the weld strength, with optimal results obtained at 30 < x < 50 at.%.

Summary: This study investigates the effect of iron impurities on the corrosion of magnesium alloys using Density Functional Theory simulations. The presence of iron is found to increase the work function of magnesium and decrease the adsorption energy of hydrogen. Furthermore, it is observed that the absorption energy of iron decreases with increasing interaction between iron atoms on the magnesium substrate. These findings provide insight into the atomic-level mechanism of magnesium corrosion.

Summary: Although high pressure enables alloying between hydrogen and iron, the hydrogen-to-iron molar ratio found in experiments is mostly limited to 1. However, we have observed a H/(Fe + Ni) ratio of 1.8 +/- 0.1 from quenched (Fe,Ni)H-x with x >= 1.8, which exceeds the amounts reported for densely packed Fe alloys. The significant H storage capacity of liquid Fe-Ni alloy is important for considering potential hydrogen storage in the interiors of low-density planets as well as rocky planets.

Summary: This study investigated the electrical and dielectric properties of Mg-doped perovskite, revealing two relaxation phenomena and a change in conductivity models at different temperatures. Activation energies were found to be sensitive to Mg composition, with different effects on grain and grain boundary contributions. The evolution of magnetization versus temperature was also measured to assess the magnetic behavior of the compounds with varying Mg content.

Summary: Ab initio calculations and crystal structure prediction algorithms were used to determine the structure and stability of iron-nitrogen compounds under different pressure and temperature conditions. Three new iron nitrides were predicted. Some iron nitrides can be stable under Earth's inner core pressures and temperatures, but they are not the major compounds in the inner core.

Summary: Bis(1-bora-4-phosphorinane) metal complexes were synthesized using a Cp*M-protecting strategy and their structures were identified by NMR spectroscopy and single crystal X-ray diffraction. The synthesis of these complexes is highly dependent on the identity of the vinylphosphine precursor. This approach offers a novel method for generating saturated P,B-containing main-group ring systems.

Summary: Terrestrial exoplanets are similar to and different from Earth, and their compositions are similar to solar-terrestrial objects. The most abundant nonvolatile elements are O, Mg, Si, Fe, Al, and Ca, but the study of Fe at ultrahigh pressures is still incomplete. By using crystal structure prediction method, several stable crystalline phases in Fe-Mg and Fe-Mg-O systems under high pressures were predicted.

Summary: Steric effects of ligand substituents on Fe(III) complexes were investigated, revealing that larger substituents maintain a high-spin state while smaller substituents exhibit spin-crossover behavior, due to the distortion of the complex structure.

Summary: The study used the adaptive genetic algorithm to investigate Fe Mg-x(y) O-z phases under high pressures, identifying three dynamically stable phases; a ternary convex hull for Fe-Mg-O was constructed, clarifying the composition- and pressure-dependence of structural motifs; analysis suggests that O, Mg, or both could stabilize a BCC iron alloy at inner core pressures.
