Summary: The appearance of composite membranes offers a new approach for reducing membrane fouling. In this study, polyaniline (PANI) and Ti3C2Tx (MXene) were combined using electrostatic assembly to create a conductive network and adjust the distance between MXene layers. The resulting MXene-PANI/PES membrane exhibited significantly improved permeation flux and retention rates compared to a regular PES membrane, while also demonstrating enhanced conductivity and anti-fouling capabilities.

Summary: This study focused on enhancing oil-membrane electrostatic repulsion in electricity-assisted membrane distillation using electrically conductive hydrophobic membrane. By coating carbon nanotubes on commercial membranes to fabricate membrane cathodes, the modified membrane showed significantly less flux decline in dealing with high-concentration oil emulsions. The anti-oil fouling robustness was confirmed through continuous operation cycles, and the study highlighted the role of electrically conductive membrane cathodes in modulating foulant-membrane interactions at the triple-phase interface to mitigate fouling/wetting issues.

Summary: In this study, hollow-structured hydroxy vanadium oxide (VOOH) was constructed, and VOOH@MXene composite material was prepared through electrostatic self-assembly. The composites have effective attenuation and absorption of electromagnetic waves. The excellent conductivity of MXene compensates for the low conductivity of VOOH, and the hollow structure of VOOH prevents the stacking of MXene sheet layers and improves the impedance matching problem. The VOM_10 composite exhibits good microwave absorption performance with a minimum reflection loss of -34.9 dB and a maximum effective absorption bandwidth of 4.08 GHz. The preparation of VOOH@MXene composites using electrostatic self-assembly and the construction of a hollow structure provide a new idea for the study of lightweight and high-performance wave absorption materials.

Summary: This study systematically investigated the fouling and backwashing of anionic polystyrene particles in microfluidic structures with engineered surface charge and hydrophilicity. The results confirmed that increasing the hydrophilicity of the membrane can reduce fouling, but hydrophilicity alone is not a sufficient measure to predict particle deposition and removal behavior. Designing a hydrophilic membrane with an engineered surface charge is crucial for achieving a low-fouling membrane that can be cleaned effectively during backwashing with pure flow reversal.

Summary: The study fabricated a composite membrane using hydrophobized MXene deposited on a PVDF support layer to improve membrane antifouling ability in seawater desalination without sacrificing permeability. The MXene-P membrane exhibited optimal desalination performance, with high water permeation flux and nearly 100% salt rejection. The membrane showed stability under actual seawater conditions and no contamination of the surface, attributed to its large water contact angle and high negative charge.

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.
