In this study, polyethersulfone (PES) hollow fiber membranes (HFM) were fabricated with different weight percentage (wt. %) of polymer at 16 wt. %, 18 % and 20 in order to study the impact percentages on membrane properties its dye rejection performance. Microfiltration HFM by using laboratory dry-wet spinning method. improve pore structure membrane, 3 (PVP) 8000 M.W. was added dope solution. A...

Laser irradiation parameters, especially the laser fluence and the number of pulses are very important factors affecting microstructures formation and improvement of the surface characteristics in different medical, electronic and the other industrial applications. Information about the fluence domain and the number of pulses for the formation of the structures is very important and determines ...
