Although jute fiber-reinforced PLA composites show strong application prospects, their low mechanical properties limit applications to some extent. In this paper, nano-SiO2 particles as well nano SiO2 modified by coupling agents which can efficiently improve the strength and toughness of composite materials are introduced into matrix. The bending, stretching thermal designed jute/PLA nonwoven w...
for the first time this study reported the success of using nanocrystalline hexagonal close-packed (hcp) nickel (ni) modified composite graphite (cg) electrode (hcp-nano ni/cg) for the electrocatalytic oxidation of glycerol in alkaline medium (0.1 m koh). the hcp-nano ni/cg electrode had an improve response and specificity on the electrocatalytic oxidation of glycerol over the bare cg. the elec...
Highly porous three-dimensional (3D) hierarchical nanostructures suspended in aqueous media were facilely prepared via electrospinning of polyacrylonitrile (PAN)/indium tin oxide (ITO) nanofibers and collection of the hybrid nanofibers by water, followed by hydrothermally growing ZnO nanorods from the nanofibers. The large inter-fiber distances facilitated the uniform growth of the ZnO nanorods...
The paper presents our new results about efficiency of wastes based on hydrolyzed polyacrylonitrile textile fibers (HPAN) as sorbents in removal of some dyes from textile effluents. The effect of some experimental variables such as initial dye concentration, sorbent mass, pH, temperature, and contact time were investigated. The sorbent dye sorption systems are described using Freundlich, Langmu...
The preparation of polyacrylonitrile (PAN) hollow fiber (HF) membranes has been carried out by dry-jet wet spinning. PAN HF membranes were coated with chitosan biopolymers 2 wt% by dip coating and further crosslinked by chemical reagents (Tri sodium polyphosphate). PAN HF (Virgin) and PAN/chitosan coated membrane were characterized by SEM and tested for water flux. Proteins Pepsin, Albumin, and...
