Summary: Due to the advantages of aesthetics, designability, convenient removal, and comfortable experience, invisible orthodontics (IO) have gained wide recognition and acceptance. However, most of the membranes used for IO only retain their shape and neglect other important functions such as antibacterial and antifouling activities. In this study, antibacterial composite membranes (ACMs) were manufactured with favorable transparency and excellent antibacterial ability. The bactericidal rates of ACMs against Staphylococcus aureus, Escherichia coli, and Streptococcus mutans were all above 99.99%. The amount of protein adhered to the surface of ACMs was also significantly low, indicating ideal antifouling performance. These multifunctional ACMs are expected to be promising alternatives for current IO treatments.

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.

Summary: A transmembrane electro-chemisorption system with authigenic acid and base was developed for enhancing ammonia recovery from strong ammonia wastewater. The system efficiently transformed ammonium into free ammonia, which was then adsorbed and recovered through transmembrane chemisorption. This system yielded pure (NH4)2SO4 product and produced valuable byproducts of pure hydrogen and oxygen. Higher applied voltage resulted in better ammonia recovery.

Summary: This study investigates the concept of using heat to enhance reverse osmosis (RO) desalination. The effect of temperature on water permeate flux, specific energy, permeate quality, and applied operating pressures is evaluated using an analytical model. The results suggest that under specific conditions, the tradeoff between savings in mechanical pump work and thermal energy input in thermally-enhanced RO can be favorable, leading to overall energy savings.

Summary: To meet the huge demand for lithium resources, there is an urgent need to develop a new efficient technology for lithium recovery from salt-lake brines. In this study, a selective membrane capacitive deionization system is reported, which achieves high lithium recovery capacity and rate through the use of materials with efficient intercalated pseudo-capacitance and a high specific area porous carbon. The use of a modified thin-coated membrane allows for selective Li+ recovery, and adjusting the concentrations of Li+ and Mg2+ in the feed solution enables higher Li+/Mg2+ selectivity.
