Silk is utilized as most valuable fibers based on the unique properties like shiny sheen, remarkable comfort performance and bio considerations. materials possess high applications a natural substrate in textile/garment industry component medical applications. As silk fine, delicate sensitive it needs more care to protect from ill effects of insects, light chemicals. Hence, this work an attempt...

tabas mines in iran have coal sources which are suitable for use in metallurgy industries as coking coal. but the high sulfur content of this coal imposes severe limitations on its utilization as the sulfur oxide gases evolved from the combustion of high sulfur coals result in acid rains and corrosion of equipments. in this work, attempts have been made to reduce sulfur from high sulfur coal of...

Abstract The tribological behavior of 316L stainless steel/CoCrMo alloy contacts under aqueous lubrication was investigated in this work. Three types microgels including poly(N-isopropylacrylamide) (PNIPAM), polyacrylic acid (PAA), and poly(N-isopropylacrylamide-co-acrylic acid) (PNIPAM-co-PAA) were prepared used as lubricant additives solutions. Tribological tests conducted using a ball-on-dis...

Abstract Salinity is a global issue limiting efficient agricultural production. Nanobiotechnology has been emerged as an effective approach to improve plant salt tolerance. However, little known about the shared mechanisms between different nanomaterials-enabled In this study, we found that both PNC [polyacrylic acid coated nanoceria (CeO 2 nanoparticles)] and PMO (polyacrylic Mn 3 O 4 nanopart...

Abstract Starch-polyacrylic acid-polyvinylsulfonic acid (St-g-PAA-PVSA) graft copoymer was synthesized by gamma radiation as an initiator. The chemical structure, morphology, and thermal stability of the copolymer were investigated using FTIR, SEM, TGA. St-g-PAA-PVSA employed adsorbent for removal Co(II) Eu(III) radionuclides from their aqueous solutions batch adsorption method. Several experim...

In this study, new material of polyacrylic acid-modified graphene oxide (GO-PAA) composite for phenol remediation from synthetic and real wastewater was investigated. The (GO) GO-PAA were physically chemically characterized using scanning electron microscopy (SEM), transmission (TEM), Fourier transform infrared spectroscopy (FTIR), energy dispersive X-ray analysis (EDX), Brunauer–Emmet–Teller (...
