Summary: In this study, beta-Ti alloys with high strengths and low elasticities were designed using first-principles calculations and experimental validations. N, O, Si, and Zr were selected as solute elements to achieve high solid-solution strengthenings and low Young's moduli in beta-Ti alloys. Among them, the beta-Ti alloy with N exhibited significant solid-solution strengthening with the highest ratio of strength to Young's modulus. This computational screening approach is believed to be effective in developing high-performance materials.

Summary: The dissolution and diffusion properties of hydrogen in transition metal carbides were studied using first-principles calculations. It was found that hydrogen tends to occupy the trigonal site in these carbides, with the bonding interaction between hydrogen and the nearest-neighbor carbon atom playing a key role in stability. Temperature-dependent solubility and diffusion coefficients were determined, with hydrogen showing poorer solubility and difficulty in migration in TMC compared to pure vanadium. Additionally, a linear relationship was observed between diffusion barrier and hydrogen solution energy in transition metal carbides.

Summary: This study reveals the adsorption mechanism of water on the C3S surface, and identifies the relationship between adsorption energy, electron transfer, and bond strength. The mechanism of water adsorption is explained by the electron transfer from the C3S surface to the water molecule, resulting in the downward shift of bonding molecular orbital. The water molecules become more structured and motionless as they get closer to the surface, and the stability of adsorption differs between isolated and bulk water.

Summary: The introduction of chemical disorder by substitutional chemistry into ionic conductors is a common strategy to stabilize high-symmetric phases while maintaining ionic conductivity at lower temperatures. Hydride materials, especially Ba2-delta H3-2 delta X, show promising ionic conductivity below 300 degrees C, opening new directions in electrochemical use of hydrogen. The layered anion order in these materials, along with Schottky defects, helps suppress structural transitions and retain a highly symmetric lattice.

Summary: This study investigates the thermal conductivity of MgO grain boundaries in nanocrystalline materials, revealing different thermal conduction scales across and along the grain boundaries. Numerical analyses show that suppressing thermal conductivity in polycrystalline materials is dominated by grain boundary scattering, while in nanocrystalline materials, the reduction of intragrain thermal conductivity along grain boundaries also plays a significant role.

Summary: Understanding the mechanisms connecting heat, electron transport, crystal structures, and defect chemistry is crucial for developing materials with thermoelectric properties. In this study, we synthesized self-doped compounds Cu2+xMn1-xGeS4 and used advanced characterization techniques to reveal the presence of interconnected nanodomains with high-density coherent interfaces. By combining experiments with ab initio calculations, we discuss the relationship between the crystal structure and thermoelectric properties, and demonstrate that substituting excess Cu+ for Mn2+ significantly enhances the power factor and figure of merit ZT.

Summary: Tin-based intermetallics with tunnel frameworks containing zigzag Na chains that excite correlated rattling impinging on the framework phonons are attractive as thermoelectric materials due to their low lattice thermal conductivity. The correlated rattling of Na atoms in the zigzag chains and the origin of the low thermal conductivity is uncovered through experimental and computational analyses. These findings reveal that phonon scattering by the correlated rattling Na chains is enhanced when there is a shorter inter-rattler distance, suggesting potential strategies for the development of thermoelectric materials with low thermal conductivity.

The calculated results show that SiP-PtS2 has good dynamic stability and suitable band gap, making it an effective material for solar energy conversion. An important feature of this heterostructure is that its band edges cross the water redox potential at pH of 0, allowing for efficient hydrogen production.

Summary: The ionic conduction mechanism in M2+-doped lanthanum oxybromide (LaOBr) was investigated through theoretical calculations and experimental analyses. The presence of dopant ions resulted in significant changes in the positions of La3+ ions, which were experimentally supported. The migration of Br- ions was found to be more probable than that of O2- ions. The evaluation of association and migration energies showed good agreement with experimental results.

Summary: This work investigates the formation of adjoining twin pairs (ATPs) at grain boundaries (GBs) in hexagonal close-packed (hcp) metals, focusing on the co-nucleation (CN) of pairs of deformation twins. A continuum defect mechanics model is proposed to study the energetic feasibility of CN of ATPs resulting from GB dislocation dissociation. The model reveals that CN is preferred over the nucleation of a single twin variant for low misorientation angle GBs. Further analysis considering GB character and twin system alignment suggests that CN events could be responsible for ATP formation even at low m' values.

Summary: This study investigates the behavior of electric-field induced antiferroelectric to ferroelectric (AFE-FE) phase transition and reveals the evolution of atomic displacement ordering as the cause for the transition behavior changing from sharp to diffuse. The novel semi-ordered configuration results from the competing interaction between long-range displacement modulation and compositional inhomogeneity, which leads to a diffuse AFE-FE transition while maintaining the switching field.

Summary: In this work, a physics-constrained neural network is used to predict grain-level responses in FCC material by incorporating crystal plasticity theory. The key feature, shear strain rate of slip system, is identified based on crystal plasticity and incorporated into the loss function as physical constitutive equations. The introduction of physics constraints accelerates the convergence of the neural network model and improves prediction accuracy, especially for small-scale datasets. Transfer learning is performed to capture complex in-plane deformation of crystals with any initial orientations, including cyclic loading and arbitrary non-monotonic loading.

Summary: This study attempts to address the gap in cooling rates between thin film deposition and bulk metallic glass (BMG) casting by correlating the glass-forming range (GFR) determined from combinatorial materials chips (CMCs) with the glass-forming ability (GFA) of BMG. The results show that the full-width at half maximum (FWHM) of the first sharp diffraction peak (FSDP) is a good indicator of BMG GFA, and strong positive correlations between FWHM and the critical casting diameter (Dmax) are observed in various BMG systems. Furthermore, the Pearson correlation coefficients suggest possible similarities in the GFA natures of certain BMG pairs.
