Summary: This study presents a facile method for synthesizing ultrathin CoFe-based LDHs and reveals their high performance in OER. The Co site is identified as the main active center, and the doping of Fe accelerates the charge-transfer process. Surface Co sites are found to be the active centers for OER, while excessive subsurface Fe doping weakens OH* adsorption and increases the energy barrier of the rate-determining step.

Summary: This study compares the techno-economy of the conventional activated sludge (CAS) process and the membrane bioreactor (MBR) process by analyzing the operating data of 20 large-scale wastewater treatment plants. The results show that after retrofitting to MBR, pollutant removal efficiency increases and energy consumption also increases, but operating costs do not significantly increase. Additionally, the environmental benefit and net profit increase. Technological efficiency, particularly cost efficiency, improves after the retrofitting. The study emphasizes the importance of effluent standards in determining the techno-economic viability of different processes.

Summary: Quantitatively characterizing the fouling potential of feed foulants is vital for the prevention and control of reverse osmosis membrane fouling. A gradient filtration method was proposed in this study to extract the fouling index of cake layer (I) for different foulants. The results showed that the cake layer was the dominant fouling mechanism, and I exhibited a linear positive correlation with foulant concentration. The combination of models in gradient filtration tests proved to be more effective in analyzing membrane fouling mechanisms. Therefore, the quantitative assessment method based on gradient filtration, combined fouling models, and the calculation of I could be useful for characterizing the fouling potentials of different foulants. This method was successfully applied to characterize the fouling potential of real wastewater.

Summary: The interaction between anodic and cathodic reactions in electrocatalytic membrane filtration (EMF) systems has great versatility in meeting complex water treatment requirements. However, current studies mostly focus on half-cell reactions with a single electrocatalytic membrane, limiting the research progress of EMF technology. In this study, a coupling strategy was developed to achieve ultra-efficient degradation performance and regulable reaction mechanisms through the interaction of anodic and cathodic reactions. A six configurations of electrocatalytic dual-membrane filtration (EDMF) system were established and systematically investigated. Based on the results, a regulation strategy for flexible tuning of direct non-radical oxidation and indirect oxidation was proposed. The findings demonstrate the versatility and tunability of the reaction mechanism and performance of the EDMF system, laying a foundation for future development of ultra-efficient and mechanism-adjustable electrocatalysis technologies.

Summary: In this study, the effect of two kisspeptin-type neuropeptides (KPs) on locomotor behavior in sea cucumbers was investigated. The results showed that AjK1 significantly reduced stride length and movement duration, leading to a decrease in movement distance, while AjK2 had little inhibitory effect at the same dose. Furthermore, the levels of certain molecules in the longitudinal muscle of sea cucumbers treated with AjK1 differed significantly from the control group, which may explain the observed changes in locomotor behavior. These findings suggest that AjK1 is more likely to play a role in the regulation of sea cucumber locomotion compared to AjK2.

Summary: Previous studies have shown that vibration- or rotation-based techniques can effectively mitigate fouling during membrane filtration. However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.

Summary: Increasing temperatures worldwide pose a significant health risk, exacerbated by high humidity. Conventional air conditioners contribute heavily to carbon dioxide emissions, with dehumidification being a major factor. Membrane-based dehumidification system offers energy efficiency and non-toxic water vapor removal. This study demonstrates a membrane dehumidification system with polymeric hollow fibers coated with a green polyphenol coating, showing remarkable water vapor transport rate and selectivity. Long-term testing reveals minimal decline in vapor transport and a 4-5 times higher coefficient of performance (COP) compared to conventional dehumidifiers, making it a highly competitive, energy-saving device with reduced emissions and a smaller footprint.
