Nanofiltration is increasingly gaining attention in many separation and treatment processes such as water softening, color removal and separation of medicines. Nanofiltration membranes are often negatively charged, displaying separation characteristics in the intermediate range between reverse osmosis and ultrafiltration. In this research, a novel nanofiltration membrane prepared with poly(amid...

The degree of dispersion of short microfibers in cement, as assessed by electrical resistivity measurement for the case of electrically conductive fibers at a volume fraction below the percolation threshold, is improved by the use of admixtures ~namely, silica fume, acrylic particle dispersion, methylcellulose solution, and silane! and fiber surface treatment ~such as ozone treatment!. Acrylic ...

Dyes are a type of pollutant that have been discharged into water streams by various industries and had harmful effects on the environment human health. Therefore, present work was directed to recycle acrylic fibers waste be used as an adsorbent exclude dyes such methylene blue (MB) Congo red (CR) from dyes-polluted wastewater. Acrylic converted membrane followed chemical grafting with p-phenyl...

STATEMENT OF PROBLEM Despite the favorable properties of conventional PMMA used as a denture base material, its fracture resistance could be improved. PURPOSE This in vitro study was performed to determine whether the flexural strength of a commercially available, heat-polymerized acrylic denture base material could be improved through reinforcement with 3 types of fibers. MATERIAL AND METH...

A significant problem associated with asphalt concrete mixtures is the lack of durability resulting from an inadequate asphalt cement content. Additional asphalt cement added to increase durability results in flushing, bleeding and a significant loss In stability. Fibers have been used in stone matrix asphalt and open-graded friction course pavements successfully throughout Europe to allow high...

This study aims to investigate the utilization of recycled textile waste fiber (RTWF) as reinforcement in cementitious lightweight composite mortars. The effect RTWF percentage on mortar (CLCM) consistency, plastic and dry set density, splitting tensile compressive strength was measured. In particular, structural mechanical properties hardened examined detail. Mohr-Coulomb Failure Criterion use...
