Summary: With the increasing use of carbon dots (CDs), a large amount of CDs will be released and accumulate in the aquatic environment. However, the potential photodegradation of CDs in the aquatic environment, as well as their accumulation and impacts on aquatic organisms, are still unclear. This study investigated the toxicity of CDs on two marine dinoflagellates and determined their bioaccumulation. Notably, significant photodegradation of CDs in seawater was observed, and both the degraded CDs and their photodegradation products were toxic to the dinoflagellates.

Summary: CQDs/Bi3O4Br composites synthesized through a mild hydrothermal method exhibited higher photocatalytic activity compared to traditional photocatalysts, effectively degrading organic dyes and pollutants in water. The enhancement of activity was attributed to the heterojunction structure formed by Bi3O4Br and CQDs, facilitating the separation of photogenerated carriers.

Summary: A facile ultrasound-assisted alcoholysis method was used to anchor BiOCl0.5Br0.5 (BOCB) nanosheets onto natural schorl particulates, enhancing the visible-light-driven photocatalytic efficiency. The synergy between the external polarization electric field of schorl and the internal polarization electric field of BOCB effectively enhanced the separation of photogenerated electron-hole pairs, contributing to the improved photocatalytic performance. This study provides a new approach for developing polarization electric field-assisted strategies to enhance photocatalytic efficiency.

Summary: In this study, nitrogen-doped carbon quantum dots (NCQDs) with different properties were prepared by using kraft lignin as the raw material and EDA as a nitrogen dopant. The amount of EDA added affected the carbonization reaction and surface state of NCQDs. The results showed that the surface defects of NCQDs increased, and the fluorescence intensity and stability improved. NCQDs also exhibited high photo-catalytic activity in degrading methylene blue under simulated sunlight irradiation.

Summary: In this study, a series of novel (BiO)(2)OHCl/BiOBr-x%B:DGNW (x = 0%, 1%, 1.5%, 2%) composites were successfully synthesized using a simple solvothermal synthesis method. The photocatalytic activity of these composites in the degradation of 5-fluorouracil (5-FU) under artificial solar radiation was assessed, and it was found that the introduction of boron-doped diamond/graphene nanowalls (B:DGNW) significantly enhanced the degradation rate of 5-FU. The results highlight the importance of B:DGNW in the separation of charge carriers and the improvement of photocatalytic activity.

Summary: The translation emphasizes on the development and application of bismuth oxyhalides (BiOX) for photocatalytic treatment of organic pollutants in wastewater. While BiOX shows good absorption of solar light, the rapid recombination rate of photogenerated charge carriers limits its practical application. To overcome this issue, the development of BiOX-based ternary nanocomposites has received significant attention.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
