Summary: This review discusses the fundamental aspects of bismuth oxyhalide (BiOX) photocatalysts in relation to their modification strategies and associated reduction mechanisms of CO2. The performance of BiOX materials is evaluated in terms of key performance metrics such as quantum efficiency, space-time yield, and figure of merit. The morphology design of BiOX materials is found to be the most efficient strategy for maximizing CO yield, while the introduction of heterojunctions is more suitable for CH4 formation. Therefore, the adoption of proper modification approaches is recommended for efficient CO2 conversion.

Summary: The concentration of zinc vacancy (VZn) was successfully regulated on hierarchical flower spherical ZnIn2S4 (ZIS) by controlling the hydrothermal temperature. Photo-electrochemical experiments showed that the carrier separation efficiency of the UCN@ZIS/SWNTs composite with different VZn concentrations had a significant improvement due to the UCN@ZIS heterojunction and charge transfer provided by SWNTs. The presence of VZn and enriched surface-active site on UCN contributed to CO2 activation and H2O dissociation, enhancing the CO2 photocatalytic reduction performance and product selectivity.

Summary: In this study, ZnIn2S4 nanosheet arrays (NSAs) were synthesized and sulfur vacancies were introduced on the surface through plasma treatment. The enhanced photoelectrochemical (PEC) performance of ZnIn2S4, including increased photocurrent and H-2 evolution rate, was attributed to improved visible light absorption and carrier separation, as well as the trapping effect of the sulfur vacancies. This work presents a novel strategy for enhancing the PEC hydrogen evolution of ZnIn2S4.

Summary: Solar-driven CO2 conversion into chemical fuels using photocatalysts is a sustainable method for renewable energy. However, the low photocatalytic activity is limited by poor photoabsorption, low charge separation efficiency, and sluggish interfacial reaction. To address this issue, a mesh cladding structure of Sr-doped LaFeO3/Bi4O5Br2 photocatalyst with abundant surface oxygen vacancies (OVs) is developed. The optimized photocatalyst with appropriate Sr doping and BOB content shows a considerable methane generation, which is significantly higher than the pristine LFO.

Summary: Rapeseed is an important oil and vegetable crop, but it is often damaged by adverse stresses. In this study, the GLYI and GLYII gene families were analyzed in rapeseed, identifying 35 BnaGLYI and 30 BnaGLYII genes. The expression profiles of these genes varied among different tissues and were up-regulated under stresses. Some BnaGLY genes also showed response to Plasmodiophora brassicae infection, and overexpression of BnGLYI11 gene in Arabidopsis thaliana confirmed its contribution to freezing tolerance.

Summary: Noninvasive photothermal treatment can tighten the skin and subcutaneous tissue, but the mechanism is not well understood. This study found that thermal injury to adipocytes increases ALOX15 in macrophages, which stimulates the production of extracellular matrix (ECM) in fibroblasts. The ALOX15 metabolite 12(S)-HETE activates the p38 MAPK signaling pathway and mediates ECM production in fibroblasts.

Summary: Aquaculture discharge is a significant contributor to antibiotic contamination, but there has been limited focus on removing antibiotics from aquaculture wastewater. This study used nine constructed wetlands with different configurations to treat aquaculture wastewater and evaluate antibiotic removal efficiency and mechanisms. The results showed that the highest removal percentages of certain antibiotics were achieved with the optimal configuration of wetlands. Microbial degradation, particularly anaerobic processes, were identified as the major pathway for antibiotic removal. In addition, specific combinations of substrate, plants, and hydraulic retention time influenced the microbial composition and oxygen conditions in the wetlands, promoting antibiotic removal.

Summary: In this study, a structure-level smart deployable truss (SDT) was further investigated based on a material-level validation of a shape-memory polymer composite (SMPC) sheet conducted in 2016. The SDT utilized a shape-memory alloy (SMA) mechanism and SMPC actuation laminates as replacements for traditional locking and driving mechanisms. Through several cycles of optimization design, a flight hardware form of the SDT that met the strict parameters of mass, size, and stiffness was obtained. Ground-based experiments confirmed that the SDT's overall structural and functional performance met China's aerospace standards.

Summary: This study investigated the prevalence of bovine tuberculosis (bTB) and its associated factors in dairy farms in Henan and Hubei provinces, China. The results showed a high animal-level (18.65%) and herd-level (93.48%) prevalence of bTB. The study also identified the practice of introducing new animals and changing disinfectant water as factors that can reduce herd positivity, and testing older cows and cows in the early or late stage of lactation as factors that can increase the odds of detecting seropositive animals. These findings have important implications for improving bTB surveillance strategies worldwide.

Summary: In this study, a multi-ant colony algorithm based on bidirectional induction mechanism and cooperative game is proposed to solve the large-scale travelling salesmen problem. By introducing a novel heterogeneous multi-population, different populations cooperate to enhance the algorithm's overall performance. A cooperative game in multi-population is proposed, and the pheromone income is distributed based on participants' contribution to balance convergence and diversity. The bidirectional induction mechanism is introduced to further improve convergence by expanding the difference of pheromone concentration between outstanding solutions and mediocre solutions.

Summary: This study focuses on the synchronization problem of multi-agent systems in directed networks under denial-of-service (DoS) attacks. The DoS attacks disrupt communication among agents and hinder synchronization. The paper presents criteria to ensure globally exponentially synchronization in insecure networks with DoS attacks of restricted frequencies and durations. Impulsive control protocols are designed to mitigate the destructive effects of the attacks. Numerical examples are provided to validate the results obtained.

Summary: This paper presents a mathematical model of VD dehydrogenation, which predicts hydrogen removal during the VD vacuum refining process and investigates the effect of controllable parameters. The model considers the behavior of argon bubbles during their uplifting and identifies three sites where the dehydrogenation reaction occurs: the surface of the Ar bubbles, the bath surface of the molten steel, and the bulk steel. The model's calculated results agree with industrial production data. The model also examines the contribution of different reaction sites and the effects of vacuum pressure, argon flow rate, and initial hydrogen content on the dehydrogenation process.
