Physical and functional properties of nonwoven textiles and other fiberlike materials depend strongly on the number and type of fiber-fiber interactions. For nanoscale polymeric fibers in particular, these interactions are governed by the surfaces of and contacts between fibers. We employ both molecular dynamics (MD) simulations at a temperature below the glass transition temperature T(g) of th...

in this work, old newspaper fibers (onf) bleached with h2o2, treated with koh and treated with naocl were investigated as potential adsorbents. the characterization of the produced fibers using ft-ir, sem and particle size distribution have been carried out and tested for the removal of ni (ii) from aqueous solutions. the results indicated that the fibers treated with koh give the highest %remo...

Polyester has been used as a prosthetic socket base. It is well documented that the raw material of base should have exhibited good mechanical properties. Prosthetic device connects an artificial limb with amputee part. In this work, seven laminated composites were prepared using vacuum technique from polyester resin and reinforced Jute, Carbon, Glass, Perlon fibers. The objective study to manu...

the environmental scanning electron microscopy (esem) is a new development in the field of electron microscopy. in this study esem has been used to study the structure of veal semimembranosus muscle. four treatments, raw (control), conventional heating, domestic and industrial microwave heating, were observed using esem. the temperature used in conventional heating was 163 0c. frequency app...

Biobased composites were successfully prepared using raw materials derived from biomass waste, i.e., an epoxy resin obtained cardanol and nanocellulose unbleached hemp fibers. The by solvent exchange impregnation of the cellulosic mat with resin, followed photocuring. Quantitative conversion was obtained, despite high amount fibers (30 wt%) their absorbance in UV region light spectrum. X-ray di...

background and aims. previous data have demonstrated that berberine, a barberry plant alkaloid, possesses various therapeutic properties. this study histologically evaluated the clinical efficacy of a berberine-derived topical gel on periodontal inflammation in patients requiring surgery. materials and methods. this randomized clinical trial was performed on 14 patient (11 females, 3 males) pre...
