Summary: Super inorganic proton conductor boron phosphate (BPO4) was synthesized and coated on multi-walled carbon nanotubes (MWNTs) through a sol-gel method with polydopamine (PDA) assistance, resulting in BPO4@MWNTs. Then, BPO4@MWNTs were dispersed in dilute chitosan (CTS) solution to prepare CTS/BPO4@MWNTs composite membranes. The well-dispersed BPO4@MWNTs and optimized interface compatibility between BPO4@MWNTs and CTS matrix contributed to the superior performances of CTS/BPO4@MWNTs composite membranes in terms of thermal stability, mechanical property, oxidation stability, proton conductivity, and power density.

Summary: In this study, aromatic molecule-modified CNTs with target single oxygen groups were synthesized and used as catalysts to investigate the explicit role of each oxygen group in the 2eORR process. The results revealed that the -C--O group was the most active component followed by the -COOH group, while the -C--O group with zigzag and armchair configurations had no apparent influence on the 2eORR performance. This work provides new insights into the nature of active sites on the oxygen-doped carbon catalysts for 2eORR.

Summary: Composite ceramic membranes based on BTM and LSM exhibit high oxygen flux values, with the oxygen permeability becoming more bulk-limited as the temperature increases. The oxygen exchange coefficients of BTM-LSM are significantly higher than its constituent phases, and introducing electronic conductivity into BTM increases the surface exchange coefficients. However, the oxygen flux of BTP remains lower compared to percolating BTM-LSM composites.

Summary: In this study, a short-range pore channels construction strategy was proposed using a gamma-ray irradiation pore-making technology to increase the in-plane porosity of GO nanosheets, enabling the rapid transmission of water molecules. The in-plane defects and d-spacing of GO were finely controlled by adjusting the irradiation dose, resulting in a significantly enhanced water permeability. The optimized membrane exhibited higher pure water permeability, dye rejection, and dye/salt separation performance compared to previously reported GO membranes. The porous membrane with short-range pore channels obtained by high-energy irradiation provides a new strategy for efficient wastewater purification and recovery.

Summary: In this research, shear-induced orientation was used to successfully prepare oriented cellulose nanocrystals (CNCs) reinforced epoxy resin composite films. The oriented CNCs significantly improved the mechanical properties of the composite films, and the aspect ratio of the CNCs also had a noticeable impact on the enhancement effect. Although the transparency of the films decreased with increasing CNC content, it was possible to obtain composite films with a transmittance close to that of pure epoxy resin film by adjusting the preparation process of CNCs. The thermal stability of the oriented CNCs reinforced epoxy resin composite films improved at low CNC content but decreased with increasing CNC content. The successful preparation of these films will contribute to the expansion of applications for epoxy resins reinforced with rod-like micro/nano fillers.

Summary: This study conducted a systematic analysis of schizophrenia seasonality in different countries and explored the effects of weather factors globally. The onset of schizophrenia in the southern hemisphere peaked in the cold season, while in the northern hemisphere it peaked in the warm season. In China, schizophrenia seasonality showed two peaks, in late cold and warm seasons. Short-term exposure to high temperature, low temperature, heatwave, temperature variation, and extreme precipitation increased the risk of schizophrenia.

Summary: In this study, PVDF-based anion-exchange membranes were designed to selectively separate nitrate from chloride. Experimental data showed that increasing the concentration of PVDF enhanced nitrate transport but also increased the membrane electrical resistance. The selectivity of nitrate was found to be independent of the membrane thickness and mainly driven by the increased affinity between the anion and the membrane.

Summary: This study focuses on the modification of a commercially available polyamide thin-film composite membrane with a zwitterionic material to enhance its fouling resistance. The modified membrane shows improved salt rejection and reduced permeability compared to the pristine membrane. Fouling tests demonstrate that the modified membrane has a lower fouling ratio and higher recovery ratio. The enhanced antifouling characteristics are attributed to the improved hydrophilicity resulting from the zwitterionic brushes and the salting-in effect.
