Summary: Doping impure atoms or introducing crystal defects can enhance the photocatalytic activity of semiconductors. In this study, a molybdenum-doped thin ZnIn2S4 material was prepared using a one-pot solvothermal method, in which the coordination of Mo doping and S vacancies enhanced visible light absorption, facilitated the separation of photogenerated carriers, and provided active sites for photocatalytic reactions. The optimized Mo-doped Sv-ZnIn2S4 exhibited a significantly higher hydrogen evolution rate compared to the original ZnIn2S4, demonstrating a new strategy for developing efficient 2D atomic photocatalysts for hydrogen evolution.

Summary: The removal efficiencies of benzene and ammonia using commercial activated carbon were studied under different relative humidity conditions and with or without visible light irradiation. The results showed that light could enhance the removal efficiency of benzene even under nitrogen, and the effect was more significant in the presence of water and oxygen. It was also found that visible light irradiation could enhance the ammonia removal efficiency under optimal humidity conditions. The study further suggested that light and water facilitated more efficient migration of NH3 through the nanoporous channels of activated carbon. Fourier-transform infrared (FT-IR) analyses revealed the changes in surface structure of activated carbon caused by oxidizing agents generated with light irradiation and other reagents.

Summary: Ce and C-S codoped mesoporous TiO2 nanocomposites were synthesized via a sol-gel method integrated with an evaporation-induced self-assembly approach. The synthesized samples were characterized and the results show that the codoping enhances the photocatalytic activity by narrowing the band gap, enhancing adsorption, trapping and transferring excited e-/h+ pairs, and suppressing recombination. The obtained C,S-TiO2/CeO2 materials have large specific surface areas and numerous pores, improving adsorption capability and providing mass and electron transfer channels. The photodegradation efficiency of RhB by C,S-TiO2/CeO2 is nearly 100% within 40 min, with a degradation efficiency 6.63 times that of undoped TiO2. The materials also exhibit excellent recoverability and stability.

Summary: Cu-doped TiO2 samples with different weight percentages of Cu loading (ranging from 1% to 4%) were synthesized using the sol-gel technique. The samples were characterized using powder XRD, SEM, and TEM. Cu-TiO2 with 1% and 2% Cu2+ doping exhibited a major anatase phase and a minor rutile phase, while samples with 3% and 4% Cu loading showed an increase in the rutile phase. UV-Vis absorption spectroscopy confirmed a decrease in the band gap of TiO2 with Cu doping. PL and XPS were used to investigate the optical properties, surface elemental composition, and oxidation state of the catalysts. Photocatalytic activity was evaluated for the removal of Rhodamine B and Cr (VI) under visible light. 3% Cu-doped TiO2 showed the highest degradation and mineralization, and the simultaneous removal of Rhodamine B and Cr (VI) was more efficient compared to individual removal.

Summary: Here, we presented the fabrication of well-crystalline metal-doped BiOCl nanoscale photocatalytic materials through solvothermal synthetic route. Ni doping significantly improved the photocatalytic and antibacterial behavior of BiOCl. The morphological study showed that different metal dopings led to the formation of nanosheet (Ni, Cd), nanoflower (Mo), and nanodisc (Co) morphologies, while Ni doping resulted in large size nanosheets with increased surface area and improved porous structure. The inclusion of Ni into BiOCl nanostructure shifted the band gap and reduced electron-hole recombination, contributing to its excellent photocatalytic performance. Additionally, Ni-BiOCl exhibited excellent photocatalytic antibacterial activity against S. aureus bacteria under visible light.

Summary: The direct electrochemical nitric oxide reduction reaction (NORR) is an attractive technique for converting NO into NH3 with low power consumption under ambient conditions. Optimizing the electronic structure of the active sites can greatly improve the performance of electrocatalysts. In this study, body-centered cubic RuGa intermetallic compounds (bcc RuGa IMCs) were prepared via a substrate-anchored thermal annealing method. The electrocatalyst showed a remarkable NH4+ yield rate of 320.6 mu mol h(-1) mg(Ru)(-1) with a corresponding Faradaic efficiency of 72.3% at a very low potential of -0.2 V vs. reversible hydrogen electrode (RHE) in neutral media. Theoretical calculations revealed that the electron-rich Ru atoms in bcc RuGa IMCs facilitated the adsorption and activation of *HNO intermediate, thus greatly reducing the energy barrier of the potential-determining step in NORR.

Summary: For the X-cube prism 3CCD camera, the spectra of the designed dichroic films in the prism shift with changes in the incident angle of light, resulting in color non-uniformity on the image plane. We optimized the thin film to improve color consistency by considering the influence of the incident angle on color performance in filter design. An optical model was used to calculate the camera spectral sensitivity distribution and correct the non-uniform color on the image plane. The results showed that the optimization and correction methods significantly improved the color performance of the X-cube prism 3CCD camera.

Summary: A universal method for synthesizing well-defined metal sulfides/TiO2 heterostructures was developed by in situ lattice sulfidation synthesis. Under hydrothermal conditions, metal atoms in metal-doped TiO2 reacted with S species to generate metal sulfides in situ on TiO2 surface. Eight kinds of MSx/TiO2 heterostructures were successfully synthesized. Taking CdS/TiO2 as an example, CdS grew tightly and dispersed uniformly on TiO2 surface. The combination with CdS greatly improved the photocatalytic NO removal ratio of TiO2, which was high compared with other works.

Summary: A study used Cu-meso-tetrakis (4-carboxyphenyl) porphine (Cu-TCPP) nanosheets with wrinkled and flat morphologies to assemble energy-efficient nanofiltration (NF) membranes by vacuum filtration (VF) and electrophoretic deposition (EPD). The membrane assembled by wrinkled nanosheets showed a higher water permeance compared to the membrane assembled by flat nanosheets, while maintaining a high rejection rate for the dye. Similarly, the membrane prepared by EPD with flat nanosheets exhibited higher water permeance than the membrane prepared by VF, with similar rejection rate for the dye. These membranes also demonstrated good separation performance under high pressure.

Summary: With the rapid development of foldable electronic devices, there is a growing interest in flexible and insulating composite films with ultra-high in-plane thermal conductivity as thermal management materials. This study successfully synthesized large quantities of Si(3)N(4)NWs using a modified CRN method and prepared super-flexible PVA/Si(3)N(4)NWs composite films using vacuum filtration. The composite films showed a high in-plane thermal conductivity of 15.4 W·m(-1)·K-1 due to the highly oriented Si(3)N(4)NWs forming a complete phonon transport network. Si(3)N(4)NWs also improved the thermal stability, electrical insulation, and mechanical strength of the composite film for thermal management applications in electronic devices.

Summary: This paper investigates the stability of hydro-turbine governing system (HTGS) with sloping ceiling tailrace tunnel (SCTT) and upstream surge tank (UST) considering nonlinear hydro-turbine characteristics (NHTCs). Firstly, a mathematical model based on a nonlinear seventh-order state equation is presented and verified by example analysis. Subsequently, the effect of HTGS parameters on the stability of the system is investigated through numerical simulation. Lastly, the coupling effect mechanism of SCTT and UST on stability under the effect of NHTCs is revealed by contrastive analysis. The results indicate that Ta, Kd, and Twt have a significant impact on the stability of HTGS, while F and Twy have a mild influence. The NHTCs are beneficial for stability under negative load disturbance but unfavorable under positive load disturbance. The coupling effect of SCTT and UST outperforms using SCTT or UST alone, and the introduction of SCTT improves stability and achieves smaller amplitude and lower frequency.

Summary: This study successfully synthesized three different hetero-interfaces by anchoring ultrafine Ru nanoparticles on various MoOx nanotube substrates. MoO2@Ru NT exhibits excellent HER activity with small overpotentials of 89 and 131 mV at current densities of 500 and 1000 mA cm(-2), respectively, surpassing other hetero-interfaces and commercial Ru/C, Pt/C catalysts. MoO2@Ru NT also shows exceptional stability for at least 100 h at 1000 mA cm(-2). Experimental observations and theoretical calculations suggest that moderate electron transfer from Ru to MoO2 enhances the water dissociation kinetics and optimizes the hydrogen adsorption/desorption, thus speeding up the HER kinetics.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
