Summary: G-C3N4 (g-CN) with edge grafting of 4-(1H-imidazol-2-yl) benzoic acid (IBA) and NiS cocatalysts showed greatly enhanced visible-light photocatalytic performance for H-2 evolution. The enhanced activity can be attributed to the synergism of edge grafting of IBA and loading of NiS cocatalysts, which improved the absorption in the visible range and effectively separated the photogenerated carriers.

Summary: The presence of heavy metals in aquatic ecosystems is a concern due to their accumulation in aquatic organisms and the toxic effects they cause. The use of dietary probiotics as a potential approach to remove heavy metals from the gut, known as gut remediation, has been discussed. However, there is a lack of comprehensive reviews on the toxic effects of heavy metals at each trophic level and the protective strategies of probiotics. This review summarizes the toxic effects of heavy metals in the organisms of the aquatic food chain and explains the potential of bacterial probiotics in alleviating toxicity and preventing toxicities caused by heavy metals.

Summary: The identity and mechanism of charge transfer process at the heterogeneous interface between heterojunction catalysts plays a crucial role in improving their stability, activity, and selectivity. In this study, a wavelength-dependent Boltzmann function is established using a continuously adjustable monochromatic light irradiation XPS technique, based on a g-C3N4/SnO2 model catalyst. The method provides a blueprint for understanding charge transfer rules and allows the calculation of electron transfer numbers, which can facilitate the development of highly active catalysts.

Summary: In this study, citrate-capped gold nanoparticles were used as a colorimetric probe for the detection of trivalent chromium ions in aqueous solution. The optimal detection conditions, such as pH and reaction time, were investigated. The results showed that the gold nanoparticles would aggregate in the presence of Cr3+ ions, and the colorimetric reaction changed from red to violet at pH 8. The Cr3+ ions were determined using naked eye and UV-vis spectrum, with a fast reaction time of 25 minutes. The platform exhibited a curve relationship between the absorbance ratio at 675 nm and 520 nm, with a detection limit of 0.9 μM. Additionally, the platform demonstrated high specificity for Cr3+ ions and held significant practical value for heavy metal ion detection.

Summary: Understanding the change in sediment load at a flood-event scale is crucial for channel regulation and reservoir operation in the Upper Yangtze River basin. This study collected field data and conducted statistical analysis to investigate the variations in runoff and sediment load during flood events. The results indicate that flood events contribute more to the annual sediment load than runoff volume. Furthermore, there is a general decreasing trend in sediment load, which can be attributed to soil conservation efforts and dam construction.

Summary: This study constructs a multicomponent photocatalyst SrTiO3/NiO/NiS with p-n heterojunction and Schottky junction, inspired by the concepts of electrons transfer layer (ETL) and holes transfer layer (HTL) in perovskite solar cells, to convert solar energy into easily storable solar fuels. The combination of NiS and NiO, which function analogously to ETL and HTL, achieves the reverse migration of electrons and holes, leading to a noticeable enhancement in photocatalytic performance. The use of in situ irradiation X-ray photoelectron spectroscopy (ISI-XPS) provides a comprehensive elucidation of the catalytic mechanism and heterojunction formation process by tracking photogenerated charges migration pathways between microscopic heterogeneous interfaces, demonstrating the capability of ISI-XPS in directly and accurately tracking charge transfer pathways and serving as an intriguing highlight within the catalyst design strategy.

Summary: In this study, an asymmetric and structurally stable gel electrolyte system was developed to address the safety concerns in lithium-sulfur batteries. This gel electrolyte exhibited high ionic conductivity, flame-retardancy, and prevented the shuttling of polysulfides and formation of lithium dendrites. The use of polyvinylidene fluoride-co-hexafluoropropylene (PVDF-HFP) and SiO2-polyvinyl alcohol (SiO2@PVA) suspension in the gel electrolyte contributed to its excellent properties. The gel electrolyte showed a high initial capacity and cycling stability in a Li-S cell, making it a promising option for the development of safe, low-cost, and durable Li-S batteries.

Summary: Constructing efficient photocatalysts for solar fuel production is important for addressing energy crisis and environmental pollution. Multiple modified multi-component photocatalysts have shown promise, but their complex structure and composition make it challenging to study their working mechanisms. In this study, an in situ irradiated X-ray photoelectron spectroscopy (ISI-XPS) method was developed to directly observe the migration route of charge carriers in a triple-modified WS2/carbon nanofibers (CNFs)/ZnIn2S4 model system. The results revealed the role of each subcomponent and demonstrated the enhanced performance of the multi-multi photocatalyst. This novel method provides a new avenue for studying photocatalytic systems and advancing the development of highly efficient photocatalysts.

Summary: This study conducted detailed time-series observations in southeast China and found that the concentrations of dissolved metal(loid)s and organic matter varied with tide levels, with higher concentrations in groundwater than in surface water. The concentrations of organic matter and metal(loid)s in surface water fluctuated oppositely with tide levels, suggesting the role of groundwater discharge. These findings have implications on the geochemical cycling of dissolved metal(loid)s and organic matter in the salt marsh-mangrove ecotone.
