Summary: Sluggish oxygen evolution reactions on photoanode surfaces significantly limit the utilization of photoelectrochemical (PEC) water splitting. Loading cocatalysts onto photoanodes has been recognized as the simplest and most efficient optimization strategy, which can decrease the surface barrier, provide more active sites, and enhance the surface catalytic reaction kinetics. However, the introduction of cocatalysts inevitably creates interfaces between photoanodes and oxygen evolution cocatalysts (Ph/OEC), resulting in severe interfacial recombination and hindered charge transfer.

Summary: FeOOH/Ni-BiVO4 photoanode synthesized by a facile wet chemical method shows improved charge transport and separation efficiency. The water oxidation photocurrent density reaches 3.02 mA cm-2 at 1.23 V vs RHE, and the surface separation efficiency is boosted to 73.3%, about 4 times higher than that of the pure sample. Ni doping promotes hole transport/trapping and introduces more active sites for water oxidation, while FeOOH co-catalyst passivates the Ni-BiVO4 photoanode surface. This work provides a model for the design of BiVO4-based photoanodes with thermodynamic and kinetic advantages.

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: 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.
