The goal of the current study is to enhance hemocompatibility polyethersulfone (PES) membranes using heparin immobilization. Heparin was immobilized covalently and via electrostatic interaction with positively charged PES surface (pseudo-zwitterionic (pZW) complex) investigate influence each method on membrane hemocompatibility. In situ synchrotron radiation micro-computed tomography (SR-µCT) i...

Nanofiltration (NF) has become a widely accepted process not only for producing drinking water but also for recovering wastewater in industrial processes or removing pollutants from industrial wastewater effluent. In the textile industry, the treatment of various dye baths with NF at room temperature have already been studied and was found feasible at lab-scale and pilot scale. The aim of this ...

In this study, polyethersulfone based nanofiltration membranes were modified by air plasma generated through dielectric barrier discharge to increase the membrane hydrophilicity aiming to improve the separation and antifouling characteristics. The effect of plasma time on the physico-chemical and separation properties of membrane was investigated. The PES nanofiltration membranes were fabricate...

Abstract Plant biology experiments in microgravity face many challenges, among which are the constraints of growth platforms available on International Space Station (ISS). Protocols for preservation and sample return to Earth often limit efficient dissection seedlings downstream tissue-specific analysis. The Advanced Experiment (APEx)-07 spaceflight experiment required a large quantity dissect...

When blood comes in contact with dialyzer membranes, the interfacial bioactivation reactions occurring at blood/membrane boundaries affect gross mechanisms related to thrombogenicity. In presence of biocompatible polymers, adhesion and subsequent interactions platelets, as well other serum components (e.g., proteins), are altered delay thrombus formation.

UNLABELLED Vancomycin is widely used in haemodialysis (HD) patients for treating infections of vascular access due to St. Aureus. To avoid subtherapeutic levels it is important to know the adequate dosing in patients undergoing haemodialysis with high flux membranes. OBJECTIVE The aim of this study was to evaluate whether HD patients treated with 1 g intravenous (IV) vancomycin reached optimu...

A microporous bisphenol A diglycidyl ether (DGEBA) epoxified-polyethersulfone (PES) blend membrane (EPES membrane) was prepared through dry-wet phase inversion. This study attempts to correlate the changes in membrane physical and chemical properties when the EPES membranes were exposed to different durations of dry-phase inversion, towards the separation efficiency of carcinogen chromium (VI)....

The mechanical stability of conventional single-channel capillary fibres can be improved in a multi-channel geometry, which has previously found application in ultrafiltration. In this work, multi-channel polyethersulfone (PES) capillary membranes comprising seven feed channels were successfully fabricated in an enhanced steam–dry–wet spinning process and coated on the inner surface with a thin...

Polymeric flat-sheet membranes and hollow fibers were prepared via UV photo-initiated polymerization of acrylic acid at the surface commercial polyether sulfones (PES) membranes. These polymeric materials permitted to immobilize efficiently palladium nanoparticles (PdNP), which exhibited a mean diameter in range 4?6 nm. synthesized by chemical reduction Pd(II) precursors presence corresponding ...
