Polyanionic candidate microbicides, including cellulose sulfate, carrageenan, PRO 2000, were proven ineffective in preventing HIV-1 transmission and even cellulose sulfate showed increased risk of HIV acquisition in the Phase III efficacy trials. Semen plays critical roles in HIV-1 sexual transmission. Specifically, amyloid fibrils formed by fragments of prostatic acidic phosphatase (PAP) in se...

Abstract High-pressure, high-temperature fractured shale reservoirs are types of unconventional that need proper drilling operations for adequate efficiency. Proper measurement fluid’s rheological properties is importance may increase the penetration rate on one hand with design. Therefore, success strongly depends design fluids. In this paper, we experimentally investigated effect potassium an...

In this study, two kinds of cellulose derivatives (polyanionic cellulose (PAC) and hydroxypropylmethyl cellulose (HPMC)) were selected as stabilizers of Pd/Fe nanoparticles (NPs) to investigate their influences on the debromination performances of 2,2',4,4'-tretrabromodiphenyl ether (BDE47). Field emission scanning electron microscope (FE-SEM) images revealed that the cellulose-stabilized Pd/Fe...

Abstract In this study, the influence of direct electric current on a microcapsule was investigated. The consisted core from calcium ion and sodium alginate (SA) complex membrane formed by polyionic complexation poly(methylene-co-guanidine) (PMCG) cellulose sulfate (CS). Microcapsules showed swelling decreasing mechanical properties under applied current, anisotropic electrode side. effect is a...

The key process parameters for the filtration loss of water-based drilling fluid (WBDF), using Arachishypogaea shells cellulose (AHSC) were optimized two-level-two factor full factorial design Response Surface Methodology (RSM). This research reveals outcomes investigations, carried out on formulation a sustainable system, where AHSC is used as additive having no toxicity and high biodegradabil...
