Summary: By using a novel integrated strategy of hydrophilic membrane modification and low-pressure operation, the permeability and anti-fouling ability of PVDF membrane were improved. The concepts of critical flux (J(C)) and threshold flux (J(TH)) were recommended as fouling-control tools, resulting in effectively reducing irreversible fouling and controlling reversible fouling. The enhancement of J(C) and J(TH) is believed to be mainly related to the better hydrophilicity and local hydraulic condition of the PVDF-TiO2 modified membrane.

Summary: The study found that increasing temperature and cross-flow velocity can improve UF separation efficiency, while the flux increase slows down after a certain transmembrane pressure. PES membranes with different pore sizes showed varying rates of flux increase under pressure changes, and using NaOH and NaClO for cleaning resulted in higher flux recovery rates.

Summary: Micro-flocculation and ozone as pretreatments of ultrafiltration have significant effects on the removal of organic matters and membrane flux. Micro-flocculation improves DOC removal efficiency but negatively impacts membrane flux. Ozone pretreatment enhances membrane specific flux but introduces dissolved organic matters hindering DOC removal. Both micro-flocculation and ozone can improve specific flux for HA simulated water, but micro-flocculation exhibits better DOC removal by avoiding the introduction of additional organic matters.

Summary: A long-term membrane resistance model was developed and simulated polymer film fouling successfully in a lab-scale membrane bioreactor (MBR). The model effectively decomposed the total fouling resistance into individual components and simulated the fouling phenomenon at different fluxes and temperatures. The relationship between flux and operation time was analyzed and a sustainable critical flux value was proposed. This study provides practical information for designing MBRs and improving the efficiency of polymer film modules.

Summary: Although membrane technology is widely used in various industries, fouling of membranes remains a significant challenge. In-situ real-time monitoring through quartz crystal microbalance with dissipation monitoring (QCM-D) can provide valuable information on the kinetics and structure of fouling layers. This study aimed to determine the extent to which observations from QCM-D relate to membrane fouling during ultrafiltration. By comparing fouling during ultrafiltration with QCM-D measurements, the study found that QCM-D findings on the attachment of foulants on polymer films are comparable to membrane fouling. This suggests that QCM-D, along with complementary analytical methods, can offer valuable insights into the development of membrane fouling in industrial wastewater treatment.

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.
