Summary: By using carboxymethyl chitosan hydrogel as a template, CuO nanoparticles wrapped into nitrogen-doped carbon nanocomposites (CuO@NCs) with abundant oxygen vacancies (OVs) were synthesized in one step. The obtained CuO@NCs showed excellent photothermal catalytic properties, achieving efficient activation of molecular oxygen under visible-light irradiation and effectively degrading bisphenol F (BPF) in complex aqueous environments and actual water matrices. Density functional theory (DFT) calculations revealed that the enhanced properties of OVs for molecular oxygen adsorption and the accelerated properties of graphitic N for electron transfer contributed significantly to the molecular oxygen activation and charge separation efficiency, resulting in a large amount of reactive oxygen species (ROS) generation.

Summary: CH4 and CO2, as greenhouse gases, can be converted into valuable syngas through solar-powered photothermal dry reforming of methane (DRM) process, which also enables solar energy collection and storage. However, conventional photothermal catalysts lack sufficient catalytic activity for enhanced light at high temperatures. In this study, a photothermal catalyst Ru/SrTiO3 is reported, which shows 1.4-1.5 times higher yields of CO and H2 compared to the thermocatalytic process under 600°C and 300-W xenon lamp irradiation. The mechanism of photothermal DRM is clarified, providing a useful guide for future solar photothermal conversion of greenhouse gases.

By using CRISPR/Cas9-mediated gene editing, we generated a homozygous ABCA7-knockout induced pluripotent stem cell (iPSC) line. This ABCA7-deficient iPSC line maintains a normal karyotype, expression of pluripotency markers, and trilineage differentiation capacity.

Summary: The close relationship between the gut microbiota (GM) and the central nervous system suggests potential strategies for treating neurological diseases. However, due to the complexity of the gut microecosystem, there is currently no theoretical framework for selecting the optimal window period and bacteria for GM interventions. In this study, a complex network-based modeling approach was used to evaluate the topological features of the GM and determine the optimal window period and bacterial candidates for interventions in Alzheimer's disease (AD). The results identified the third month after birth as the optimal window period for GM interventions and suggested specific hub bacteria as potential candidates for interventions.

Summary: Carrier transport plays a crucial role in enhancing photocatalytic efficiency, especially in organic photocatalysts with indefinite structures and low crystallinities. In this study, we develop a strategy to enhance carrier transport in IMZ-alkyl-PDI photocatalysts by controlling the p-p stacking distance. Among different alkyl groups, ethyl-linkage exhibits the shortest p-p stacking distance and leads to the fastest carrier transport. IMZ-ethyl-PDI shows remarkable enhancement in phenol degradation and oxygen evolution rate, as well as high-flux phenol removal in microchannel reactors. These findings provide valuable insights for molecular design of high-performance photocatalysts and elucidate important carrier transport mechanisms.

Summary: The influence of amorphous silicas (nano-silica and silica fume) on the mechanical contribution of coarse aggregates (CA) in Ultra-High Performance Concrete (UHPC) is investigated. Results show that silica fume generates more C-S-H and microcracks due to its higher content, while nano-silica results in a higher percentage of high-density C-S-H. The fracture of CA in pure tensile cracking is controlled by the competition between high-density C-S-H content and microcracks, whereas the fracture of CA in pure shear cracking is governed by microstructure compactness.

Summary: This study comprehensively investigates the hydrophobicity properties and reaction products of FSBG modified by isooctyltriethoxysilane admixture to reveal the mechanisms involved in the generation and evolution of hydrophobization effect. The reduction of porosity is caused by the siloxane products of silane after condensation reactions and thus does not show consistencies to the decreasing compressive strength as well as the formation of hydration products. The evolution of contact angle on the surface of modified FSBG is dependent on the mutual effect of superficial density of silane and porosity, with the former controlled by the amount of coupling sites.

Summary: A novel triazine-based covalent organic framework (TFPT-Bz COF) was synthesized using deep eutectic solvent (DES) as the reaction medium for the condensation of 2,4,6-tris(5-formyl-2-pyridinoxy)-1,3,5-triazine (TFPT) and benzidine (BZ). Pd ions were introduced into the TFPT-Bz COF matrix, resulting in the TFPT-Bz COF/Pd composite which exhibited excellent catalytic activity for C-H arylation of azoles with aryl halides in 2-methyltetrahydrofuran. The protocol allowed for the efficient arylation of various substituted azoles with diverse aryl halides in high yields, and the TFPT-Bz COF/Pd catalyst could be recycled multiple times without significant loss in activity.

Summary: This study assesses the combined toxic effects of cadmium (Cd) and aniline using a bacterial consortium as a model system. The results show that the consortial bacteria have stronger tolerance to Cd and aniline compared to single species. The joint toxicity of Cd and aniline displays a concentration-dependent behavior. Aniline retards the cellular accumulation of Cd and increases enzymatic activities. The bacterial community undergoes compositional changes under single and combined toxicities.

Summary: This study presents a convenient and efficient strategy for Fe doping into BiVO4 and hybrid CoO(x) OECs to achieve a Fe-BiVO4/CoO(x) photoanode. The resulting photoanode demonstrates a photocurrent density of 4.0 mA/cm2 and high charge transfer (74.4%)/separation efficiency (71.2%) at 1.23 V vs RHE under AM 1.5 G illumination. The synergistic effect of Fe doping and CoO(x) OEC loading significantly enhances the electrical conductivity and carrier density of BiVO4. This work provides valuable experimental data for improving the PEC performance of BiVO4.

Summary: This study investigated the mental health of Chinese civil servants during the COVID-19 pandemic. The results found a high prevalence of anxiety, depression, and insomnia among civil servants, with low self-reported risk at work and support from mental health workers. Higher-ranking civil servants had lower levels of anxiety and depression. Poor perceived health status was associated with more mental health problems. Social support and work-family conflict significantly mediated the relationship between occupational stress and mental health problems.

Summary: Using a low-cost, 2D semi-paracrystalline conjugated polymer PTQ10 as the second polymer donor, we achieved improved photovoltaic and mechanical performance in PM6: PTQ10: N3-based organic solar cells (OSCs), compared to OSCs based on the benchmark PM6: N3 blend. By studying the effects of the second polymer on the mechanical and photovoltaic properties of the ternary blend system, we gained a deeper understanding of the relationship between film structure and mechanical properties in such systems. This work also provided a theoretical model for predicting the elastic modulus of these ternary blend films composed of dual-donor polymers.
