In this study, we developed a novel nanocomposite-based membrane using maghemite copper oxide (MC) to enhance the separation efficiency of poly(vinyl chloride) (PVC) membranes for oil-in-water emulsions. The MC nanocomposite was synthesized co-precipitation method and incorporated into PVC matrix by casting. resulting demonstrated high degree crystallinity well-dispersed nanostructure, as confirmed TEM, SEM, XRD, FT-IR analyses. performance evaluated in terms water flux, solute rejection, anti-fouling properties. pinnacle unequivocally reached with solution dosage 50 mL, concentration 100 mg L

Nanobubble cavitation presents an effective method for the degradation of polyacrylamide (PAM) wastewater. However, efficiency bubble energy utilization remains suboptimal, and underlying mechanisms require further elucidation. In this study, molecular dynamics simulations were employed to investigate PAM by modeling various nanobubble configurations spatial arrangements. The results indicate that collapse nanobubbles generates high-velocity jets in central region, causing deformation chains is proportional both impact velocity size. mechanism induces turbulent vortices due strong shear forces, while discontinuities local density, velocity, pressure lead formation secondary shock waves. Higher velocities larger sizes found enhance efficiency. Specifically, effects following induce stretching C–C single bonds expansion C–C–C bond angles main chain, resulting fragmentation long-chain structures into shorter segments. Notably, undergoes mechanical during process, with its chemical structure largely maintained breakage points primarily concentrated region bubble. Additionally, increasing number bubbles does not necessarily improve Different multi-bubble arrangements significantly influence distribution kinetic post-collapse. Horizontal arrangements, particular, demonstrate enhanced through superposition waves on chains, thereby maximizing utilization.
