Summary: Ru/Ce0.5La0.5-xTixO1.75+0.5x solid solutions with cubic fluorite structure were successfully synthesized via the polymerized complex method. The Ti substitution enhanced Ce4+ reducibility, but the reducibility showed no correlation with ammonia synthesis activity. Ru/Ce0.5La0.4Ti0.1O1.8 exhibited the highest activity, likely due to the facilitated formation of mesopores.

Summary: By preparing a concentration series of Y3Al5O12:Ce solid solutions, the composition with the highest X-ray luminescence intensity was identified. Luminescent diamond-Y3Al5O12:Ce composite films were synthesized using microwave plasma-assisted chemical vapor deposition (CVD) in methane-hydrogen gas mixtures based on the optimal composition. The luminescence intensity of the composite films could be fine-tuned by varying the amounts of embedded Y3Al5O12:Ce powders.

Summary: Three stacking interface models were constructed based on the relative positions of the C(111) surface and Ti(112_0) surface using the first-principles method. The interfacial adhesion and energy, as well as the electronic characteristics and maximum tensile stress values, were calculated and analyzed. The results show that the 2nd-C(111)/Ti(112_0) interface has better interfacial adhesion properties compared to the 1st-C(111)/Ti(112_0) and 4th-C(111)/Ti(112_0) interfaces.

Summary: We report the electric field-induced out-of-plane ferroelectric polarization in large-scale, freestanding, and strain-free 2D STO membranes at room temperature. High-resolution piezoresponse force microscopy measurements show that polarization in freestanding strain-free STO membranes can be switched by electric field and persist for an hour. Our work unlocks the great potential of freestanding 2D STO for the applications in novel electronic and logic-in-memory devices.

Summary: Using N+-ion implantation at 200 keV with varying fluences, highly conducting n-type diamond can be formed with insulator-to-metal transition observed. Low and medium fluence implantation preserves the long-range order in diamond films, while high fluences lead to the formation of a disordered amorphous carbon network with metallic conduction. Single crystal diamond retains long-range order even at high fluences, with percolative transport occurring through defects or semi-amorphized regions.

Summary: Superior mechanical properties have been achieved in a coarse-grained single-phase face-centered cubic (fcc) medium-entropy alloy (MEA) by carefully designing multi-scale heterogeneous structures. The alloy exhibits high ultimate tensile strength and fracture strain, mainly attributed to the favorable heterogeneous fcc matrix, coherent spherical precipitates, and a high density of crystalline defects.

Summary: This study investigates the potential of Spanish germplasm for creating hybrids suitable for southern Europe, an untapped region for hybrid barley. A total of 140 locally adapted, advanced breeding lines from a Spanish breeding program were examined to expand the germplasm options for hybrid barley development. Through field trials and genomic predictions, lines with high general combining ability were identified for potential two-way hybrid production. The presence of brittle mutations in hybrid combinations, discovered through field trials, underscored the need for further research on heterotic patterns and proper management of brittle genes to broaden the germplasm pool for hybrid barley breeding.

Summary: The nucleation mechanism of CH4/CO2 hydrates in kaolinite particles with different gas concentrations was studied using molecular dynamics simulations. The results showed that the interaction between adsorbed CH4/CO2 molecules and the siloxane surface played a crucial role in hydrate nucleation, while the hydroxyl surface had a minor contribution. These findings provide molecular insight into CH4/CO2 gas separation and CO2 sequestration.

Summary: The twinning mechanisms in pure Ti, including {11 (2) over bar1} twinning and {11 (2) over bar2}-{11 (2) over bar1} double twinning, are systematically investigated using molecular dynamics simulations. The migration of {11 (2) over bar1} twin boundaries is mainly carried out by the slip of twinning dislocations. Two double twinning mechanisms, involving the formation and growth of {11 (2) over bar1} twin at the {11 (2) over bar2} twin tip, are discovered. The interfacial structures of {11 (2) over bar1} twins exhibit terraced character with short coherent facets and coherent twin boundary segments.

Summary: Superplastic deformation of polycrystalline materials is usually achieved by diffusion-assisted grain boundary sliding at high temperatures. Recent research has shown that room-temperature superplasticity can be achieved in ultrafine-grained Al-Zn based alloys, but the underlying mechanism is still unclear. This study utilized in-situ tensile straining, electron microscopy characterization, and atomistic density functional theory simulation to reveal that the superplasticity at room temperature is achieved by grain boundary sliding and grain rotation, facilitated by the continuous diffusion of Zn. The diffusion of Zn atoms from grains to grain boundaries forms a Zn nanolayer, acting as a solid lubricant to lower the energy barrier of grain boundary sliding.

Summary: Vaporization is a significant consequence of giant impacts in planet formation. The last giant impact during the early history of our planet resulted in the formation of a highly vaporized disk that condensed onto the Earth and Moon. This study investigated the thermodynamic state of the disk and its condensation process, finding that the mantle and post-impact Earth reached critical temperatures and pressures. The atomic structure of the silicate fluid within the disk varied with radius, leading to the presence of short-lived chemical species in the outer parts and long-lasting dense polymers in the deeper parts. The condensation of silicate vapor during cooling resulted in the dominance of species along the mantle vapor curve in the post-impact atmosphere.

Summary: The chlor-alkali process is important in the chemical industry due to the diverse usage of chlorine gas. However, current chlorine evolution reaction (CER) electrocatalysts have inefficiencies that result in high energy consumption. This study presents a highly active single-atom ruthenium catalyst for the electro synthesis of chlorine in seawater-like solutions. The catalyst exhibits low overpotential and high stability and selectivity, offering potential for efficient chlorine production from seawater.

Summary: It has been found that carbonate melts may exist in the lower mantle, but their interaction with other lower mantle melts is not well understood. By simulating different melt mixtures, researchers studied the evolution of Gibbs free energies of mixing with pressure. The results reveal that carbonate-metal and carbonate-silicate melts become miscible with increasing pressure, while silicate-metal melts remain immiscible. Further analysis suggests the existence of three miscible melt fields near the endmember carbonate, silicate, and iron compositions at the core-mantle boundary. The study also highlights the potential role of carbon-rich and silicate-rich melt compositions in explaining ultra-low velocity zones.
