Summary: Nickel coatings with different surface characteristics were prepared on copper substrate by electrodeposition. The effects of etching time on surface morphology, roughness and wettability were investigated. The results showed that long-time physical aging formed multiple polygonal-layered architectures and larger-sized layered micro-structure, which maintained high surface free energy and good hydrophilic state, and provided a reference for optimizing the surface morphologies of casting rolls to improve heat transfer efficiency and promote heterogeneous nucleation.

Summary: This study describes a low-cost, electro-mechanical tilting table to measure leaf wetting and drainage characteristics of different taxa. The experiment on Homolanthus populifolius reveals complex behavior in which the open leaf surface is hydrophobic but major adaxial veins are strongly hydrophilic and can trap droplets. The apparent droplet roll-off angles are dependent on the tilt speed applied.

Summary: This study investigates the surface properties of methyl-terminated organosilica films modified by atmospheric-pressure water vapor plasma. Plasma modification leads to an immediate decrease in water contact angle, as methyl groups are oxidized to form oxygen-containing groups. The films show a moderate hydrophobic recovery after certain treatment. The changes in surface hydrophilicity during long-term storage are attributed to the rotation of Si-OH.

Summary: This study investigates the influence of contact angle (CA) and contact angle hysteresis (CAH) on humid air condensation and reveals their different roles in different stages of the condensation cycle. The findings show that increasing CAH has a negative effect on condensation heat transfer, while the impact of changing CA varies. Lower CAH values have a greater impact on enhancing condensation heat transfer, and increasing CAH has a more significant effect on hydrophobic surfaces than on hydrophilic surfaces. Additionally, decreasing CAH has a more pronounced effect on improving condensation heat transfer than increasing CA.

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: 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.
