Poly(vinyl alcohol) (PVA)/polyethersulfone (PES) composite membranes were fabricated using two PVA polymers with molecular weights of 50,000 and 15,000 different crosslinker agents. The membrane the top layer consisting formaldehyde as found to have a better separation factor than others for pervaporative dehydration isopropanol. While adding 1.0 wt% graphene oxide could represent pervaporation...

BACKGROUND The incidence and mechanisms of acute and late stent malapposition after primary stent implantation in ST-segment elevation myocardial infarction remain unclear. METHODS AND RESULTS The Harmonizing Outcomes with Revascularization and Stents in Acute Myocardial Infarction (HORIZONS-AMI) trial was a dual-arm, factorial, randomized trial comparing paclitaxel-eluting stents (PES) and o...

The Korean prostrate spurge Euphorbia supina (Euphorbiaceae family) has been used as a folk medicine in Korea against a variety of ailments such as bronchitis, hemorrhage, jaundice and multiple gastrointestinal diseases. Polyphenols from Korean E. supina (PES) which include quercetin and kaempferol derivatives have anticancer properties. Hence, we investigated the anticancer effects of PES on U...

Abstract The increasing occurrence of steroidal hormone micropollutant in the aquatic environment and their associated consequences have caused serious environmental concerns globally. Adsorptive removal hormonal pollutants using polymeric membranes has been suggested but information on performance various conditions is lacking. In this study, we examined effect salinity polyethersulfone (PES) ...

In this study, RuO2-embedded PES membrane was prepared and it used for protein separation. The antifouling properties of the fabricated composite membranes were also investigated using bovine serum albumin (BSA) as solution. mean roughness increased proportionally by introducing RuO2 particles. porosity higher than that pristine membrane. On other hand, has smaller average pore size after addit...

The fouling behaviour of microcrystalline cellulose (MCC) particles on polyethersulfone (PES) membranes was investigated using fluid dynamic gauging (FDG) and molecular dynamics (MD) simulations. Experimental cross-flow microfiltration (MF) a dilute MCC suspension at 400 mbar transmembrane pressure 0.45 μm PES revealed an estimated layer thickness 616 ± 5 for both fouled re-fouled applied shear...

Removal of endocrine disrupting compound (viz., bisphenol A, BPA) by laboratoryfabricated hollow fiber polyethersulfone (PES) nanofiltration (NF) membranes have been investigated. The tailor made charged PES hollow fiber NF membranes have been developed by blending negatively charged surface modifying macromolecule (cSMM). It is resulted more than 90% removal of BPA, mainly due to negatively ch...

Background: Hemodialysis is a process of removing waste and excess fluid from blood when kidneys cannot function efficiently. It often involves diverting blood to the filter of the dialysis machin to be cleared of toxic substances. Fouling of pores in dialysis membrane caused by adhesion of plasma protein and other toxins will reduce the efficacy of the filtre.Objective: In This study, the infl...
