Summary: A well-designed hierarchical BixOyIz nanoflowers with oxygen defect was obtained by regulating the calcination temperature of BiOI to enhance charge transfer driving force. Oxygen-deficient Bi4O5I2 exhibited prominent visible light photocatalytic degradation performance towards antibiotic tetracycline (TC) and bisphenol A (BPA) due to its strong attraction effect to electrons and stronger oxidation capability. The removal rates for TC and BPA could reach 100% within 10 min and 30 min, respectively, which are significantly higher than that of BiOI.

Summary: Recently, halide perovskites, especially all-inorganic CsPbBr3, have gained increasing attention in the field of photocatalysis due to their superior optoelectronic properties and thermal stability. However, there is limited research on their application in thermocatalysis and photo-thermocatalysis. In this study, a core-shell heterojunction composed of CsPbBr3 nanoparticles encapsulated with a 2D C3N4 (m-CN) layer was rationally designed. The results showed that m-CN@CsPbBr3 significantly improved CO2 capture and charge separation, and effectively drove the thermocatalytic reduction of CO2. When coupled with light, the activity for CO2-to-CO reduction was further enhanced, surpassing that of pure photocatalysis and thermocatalysis. This work expands the application of halide perovskites and provides guidance for utilizing perovskite-based catalysts in photo-assisted thermocatalytic CO2 reduction.

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.
