Summary: Hydrogen isotope storage in the form of deuterium and tritium has gained increasing attention from researchers, and ZrCo alloy is considered a promising material for this purpose. However, its poor cycle life and capacity retention have hindered its practical application. In this study, a co-substitution strategy of Nb for Zr and Ni for Co in ZrCo alloy is proposed to overcome these drawbacks. The Zr0.8Nb0.2Co0.8Ni0.2 alloy shows superior cycle life (97.6% retention) and remarkable capacity (2.42 H (f. u.)) in 100 cycles, outperforming existing hydrogen isotope storage alloys. These improvements are attributed to the stable homogenous structural phase transformation and ordered migration mechanism of H atom.

Summary: The Prussian blue analogue Co3[Co(CN)6]2 (CoCo-PBA) nanoparticles with three-dimensional cubic structure and uniform size are prepared using the precipitation method. The porous Co9S8/N-doped carbon (Co9S8-NC) nanostructure is fabricated via heat treatment and sulfidation processes using CoCo-PBA as the precursor. The porous Co9S8-NC is mixed with RGO by ball milling to enhance the conductivity and electrocatalytic activity. During the electrochemical hydrogen storage test, the porous Co9S8-NC exhibits higher discharge capacity than conventional Co9S8. The conductivity of Co9S8 is enhanced due to the existence of N-doped carbon. The special porous structure and large specific surface area derived from CoCo-PBA provide more electrochemical active sites. Moreover, the electrochemical properties further improve after RGO modification because of the outstanding characteristics of RGO. A highest discharge capacity of 640.8 mAh/g is obtained for the Co9S8-NC/RGO electrode. Additionally, the cycling stability, HRD and kinetic properties are also enhanced with the addition of RGO. As a consequence, Co9S8-NC/RGO can be regarded as a promising material for electrochemical hydrogen storage.

Summary: The study uses quantum chemistry modeling to accurately determine carbon and hydrogen isotope fractionation factors for butane isomers at equilibrium, showing temperature dependence of these effects. Higher-order energy terms are found to contribute significantly to isotope effects, comparable to current experimental precisions. In addition to anharmonicity, the contribution of hindered internal rotation and diagonal Born-Oppenheimer correction is important for accurate predictions of hydrogen isotope equilibriums.

Summary: Photocatalytic technology utilizing sunlight as a driving force can convert solar energy into other energy sources for storage and use. CdS, as a typical reducing semiconductor, has attracted attention in photocatalysis due to its suitable bandgap and strong reducing ability. However, the photocatalytic performance of CdS is limited by carrier recombination and photocorrosion. Therefore, CdS has been widely developed as a reducing photocatalyst in constructing S-scheme heterojunctions to overcome these limitations.

Summary: A novel compliant spinal fixation based on compliant mechanisms is designed to effectively reduce stress-shielding effect and adjacent segment degeneration (ASD), but it requires high properties of the used materials. Bulk metallic glasses (BMGs), as young biomaterials, demonstrate excellent comprehensive properties, making them attractive for compliant spinal fixation. In this study, the large deflection deformation behaviors of Zr61Ti2Cu25Al12 (at.%, ZT1) BMG beam were systematically investigated, including elastic, yielding, and plastic deformations. The theoretical nonlinear analytical solution curve predicts the load-deflection relation within the elastic deformation regime and assists in capturing the yielding event, serving as a powerful design tool for engineers. To accurately capture the beginning of the yielding event in biomedical implant applications, the concept of bending proof strength (sigma p,0.05%) with tiny permanent strain of 0.05% was proposed and determined, which is significant for setting the allowable operating limits of the basic flexible elements. The plastic deformation driven by the bending moment can be classified into two stages: the initial stage characterized by nucleation and intense interaction of shear bands, and the second stage dominated by the progressive propagation of shear bands and emergence of shear offsets. The plasticity of BMG beam structures depends on the BMG's inherent plastic zone size (rp), and when the half beam thickness is less than that of rp, the plastic deformation of BMGs behaves in a stable manner, effectively serving as the margin of safety.

Summary: The bainite transformation in medium Mn steels has been experimentally and theoretically studied, and it has been found that the transformation kinetics is slow. However, the introduction of dislocations can significantly accelerate the transformation rate. A new "carbon depletion mechanism" is proposed to explain the role of dislocations in the acceleration of bainite transformation, and a physical model is developed to quantitatively understand the kinetics of bainite transformation.

Summary: Fe-based metallic glasses are promising materials in the fields of advanced magnetism and sensors. This study proposes a novel approach to tailor the amorphous structure through liquid-liquid phase transition, and provides insights into the correlation between structural disorder and magnetic order. The results show that the liquid-liquid phase transition can induce more locally ordered nanodomains, leading to stronger exchange interactions and increased saturation magnetization. The increased local heterogeneity also enhances magnetic anisotropy, resulting in a better stress-impedance effect.

Summary: Metal-organic frameworks derived composites are promising EMW absorbers. Cation substitution can improve their absorption performance by regulating morphology and atomic space occupation. However, the mechanisms of how cation substitution affects EMW absorption performance are still not well understood. In this study, imidazolic MOFs were fabricated and tailored by cation substitution strategy to prepare porous composites. The samples showed optimal reflection loss and effective absorption bandwidth values under low filling rate and thin thickness conditions. The intercoupling between multiple atoms and the porous structure introduced by cation substitution contribute to the improved absorption performance.
