Summary: A high-pressure yttrium allotrope, hP3-Y, was synthesized and its stability and electronic properties were studied. Derivative hydrides, hP3-YHx, with different hydrogen contents were also synthesized. Similar structures were found for hP3-NdHx and hP3-GdHx hydrides. These results are significant for understanding the behavior and properties of materials under high pressure.

Summary: By studying the lattice strain in rutile-type RuO2 epitaxial thin films grown at different temperatures, it was found that the strain is influenced by growth-mode-induced effects and thickness. Within a certain range, the lattice strain had no significant impact on the electrical properties of RuO2, ensuring its reliable applications as catalysts and electrodes.

Summary: Na3.6Lu1.8-x(PO4)(3):xEu(3+) phosphors were synthesized by high-temperature solid-state reaction, and their structure and optical properties were studied. The study found that the highest Eu3+ luminescence intensity was achieved when x = 0.5, but further increase in Eu3+ content led to concentration quenching. In addition, enhanced temperature stability of Eu3+ emission was observed at an excitation energy of 3.23 eV.

Summary: This paper investigates the magnetic spin structure and phase transition in CoVO3. The experimental results show that the spins of Co2+ form a zigzag order on the honeycomb lattice without an external magnetic field. A weak ferromagnetic phase transition is observed in CoVO3 under specific magnetic fields. These findings are significant for understanding the magnetic behavior of CoVO3 material.

Summary: A family of edge-sharing bi-octahedral (ESBO) diruthenium(III,III) compounds has been prepared by reacting Ru-2(R'CO2) (+)(4). These compounds have a similar ESBO structure, with the Ru atoms bridged by two mu-O2CR' and two mu-OR in a trans manner, and each Ru atom coordinated with an eta(2)-L ligand. The Ru-Ru distances fall in the range of 2.4560(9)-2.4771(4) angstrom. The compounds exhibit strong absorption bands at around 345 cm(-1) in the Raman spectrum, which can be assigned to the stretching of the Ru-Ru single bond.

Summary: The growing interface structure of pearlite in 100Mn13 high carbon high manganese steel was investigated using SEM and TEM after solution treatment at 1323 K and subsequent aging treatment at 823 K. The results show that longer pearlite lamellae, consisting of ferrite and cementite lamellae, are formed in the initial growth stage of the pearlite colony, with protrusions and branches present in the M3C/g interface. The cementite lamella is divided into two parts along the (010) M3C plane, which differ in terms of edge dislocations and (010) M3C lattice arrangement. Additionally, the wavy morphology of the ferrite lamella's edge interface, including two peaks with small curvature radius, accommodates more C atoms and accelerates the transformation process. Physical models for the growth of cementite lamella with protrusions and branches, and ferrite lamella with two peaks and three troughs, are proposed.

Summary: MS-1 is a small-pore iron silicate with a 3D porous system, an analogue of the rare mineral imandrite. It is the lowest framework density iron silicate, one of the most siliceous (Si/Fe = 6) iron silicates, the first iron cyclosilicate achieved at hydrothermal conditions, and the only synthetic iron-based member of the lovozerite mineral group.

Summary: In this study, various ruthenium complexes were synthesized, characterized, and evaluated for their cytotoxic activity against different cell lines. The complexes showed activity in the lower micromolar range and exhibited higher efficacy than cisplatin, with one complex inducing apoptosis and caspase activation in a cisplatin-resistant cell line.

Summary: In this study, a new orthorhombic polymorph of yttrium carbide, gamma-Y4C5, was synthesized under high pressure conditions. The structure includes carbon groups such as [C-2] dimers and [C-3] trimers, with unusually high noninteger charges and unique bond orders. These results expand the understanding of possible carbon states at extreme conditions.

Summary: The study investigates the effect of alloying Ru with Fe2P on the hydrogen evolution reaction (HER) performance. The results show that Ru acts as an electron dopant, leading to a decreased water dissociation barrier and an improved electron-transfer Volmer step. The (2 (1) over bar1) facet of Ru-Fe2P is found to be more active than its (001) facet.

Summary: During the spheroidizing annealing process, the dissolution and coarsening progress of different initial structures are asynchronous due to varying interlamellar spacing. The granular cementite in the spheroidized structure is fine, uniform, and dense. The initial structure of degenerated pearlite (D-P) is highly sensitive to the austenitization temperature, with cementite easily coarsening under high temperatures.
