-fiber ultrafiltration membrane and its cleaning efficiency by streaming potential and flux method QIU Yun-ren(邱运仁), MIAO Chang(缪 畅), YE Hong-qi(叶红齐) (School of Chemistry and Chemical Engineering...; Abstract: Polysulfone (PS) hollow-fiber ultrafiltration membrane was characterized combined with flux and streaming potential in single electrolyte solutions......
, the secondary dendrites and precipitates are reduced, while the solute partition coefficient and solute solid-solubility are raised. Ultimately, downward travelling magnetic fields can increase...Optimizing the microstructures and mechanical properties of Al-Cu-based alloys with large solidification intervals by coupling travelling magnetic fields with sequential solidificationLei......
produced by twin-roll casting(TRC processes without and with multi-electromagnetic fields fo Al–Zn–Mg–Cu alloy at 670 °C were investigated in detai by means of optical microscopy(OM) and electron probe..., and replaced by numerous bulk depositions. EPMA analysis shows that the added atoms are diffused from deposition to a(Al) matrix, resulting in that the solute concentration in and around the precipitates......
evolution due to the difference in diffusion flux of Co and Si atoms through the native oxide layer. The high magnetic fields had considerable effect on the morphology evolution by accelerating nanoscale Kirkendall effect. The diffusion mechanism in the presence of high magnetic fields was given to explain the increase of diffusion coefficient. The morphology evolution of Co films on native oxide......
