Summary: A novel simulation methodology was developed to analyze the dynamics of hybrid induced phase separation (HIPS) at a multiscale level. The method combined dissipative particle dynamics (DPD), molecular dynamics (MD), and extended Maxwell-Stefan (MS) equations. The simulation results indicated that the mass transfer played a decisive role in the phase separation near the interface, resulting in an asymmetric structure with a denser polymer top layer and porous sublayer. The multiscale simulation provided deep insights into the membrane formation via the HIPS process.

Summary: In this study, porous polyethersulfone (PES) membranes were prepared with the addition of polyvinylpyrrolidone (PVP) and tri-n-octylphosphine oxide (TOPO) to selectively remove p-cresol from simulated serum. The adsorption isotherms and cross-flow adsorption showed the high selectivity of p-cresol clearance using the prepared TOPO-mixed membranes. Hemolysis tests and cell viability measurements demonstrated the hemo- and bio-compatibility of the membranes. This study has important implications for improving the treatment of patients with end-stage renal disease.

Summary: Ultrafiltration membranes derived from block copolymers with tunable pore structures and intrinsic surface functions are prepared by a simple spray-coating method. The addition of water as a pore-forming agent leads to phase separation during spray coating, resulting in the formation of nanoscale pores in the composite membranes. The membranes exhibit good ultrafiltration performance and intrinsic fouling resistance, making them comparable or better than those prepared by more complicated processes.

Summary: The separation of substances into different phases is a common and important phenomenon in nature and has scientific and technological significance. When the species involved can interconvert, the presence of a strong external force can result in equal amounts of both alternative species and the observation of steady-state, restricted phase separation. This study uses simulations to investigate the formation of such mesoscale steady-state structures in binary mixtures that exhibit both equilibrium and forced interconversion, and shows that a nonequilibrium thermodynamic theory can explain the main trends and observations.

Summary: Superhydrophobic and antibacterial polyurethane nanocomposite films loaded with TiO2 and graphene nanoparticles were fabricated via a spray coating technique. The combination of TiO2, graphene, and nonsolvent led to a hierarchical structure with high uniform surface roughness, resulting in superhydrophobic/roll-off behavior and increased antibacterial activity to around 99%. The presence of TiO2 and graphene nanoparticles in the nonsolvent-induced phase separation (NIPS) process played a significant role in promoting the surface properties of the films.

Summary: The NIPS method was used to prepare PLA films with 10wt% NMP, which showed uniform porous structures and improved thermal stability, water vapor transmission, and oxygen permeability. The addition of NMP altered the crystalline properties of the films, but not their composition. The 10 wt% NMP/PLA film demonstrated a longer shelf life for pork compared to polyethylene film, indicating its potential in pork packaging.

Summary: Phase inversion processes are widely used in manufacturing polymeric membranes, but the understanding of the connection between process variables and final membrane structure remains largely empirical. Modeling efforts have primarily relied on heuristics correlating experimentally observed pore structures with process conditions, with recent developments introducing mesoscopic phase field approaches and molecular simulations to improve accuracy. This review aims to inspire further progress in modeling development for membrane preparation by phase inversion processes.

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.
