In this work, CoFe2O4 nanoparticles have been prepared by co-precipitation technique. The synthesized CoFe2O4 nanoparticles were applied in the preparation of CoFe2O4/Polyacrylonitrile fiber nanocomposites by the electrospinning process. The prepared nanoparticles and nanofibers were characterized using the Scanning Electron ...

asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...

Particulate matter (PM) pollution has become a serious threat to human health. Accordingly, an air filtration media that can efficiently remove particulate should be developed immediately. Nanofibrous membrane filter prepared by electrospinning technology nanoscale diameter, high specific surface area, and relatively porosity, which are suitable for dust removal. This paper explored the effects...
