Abstract The excessive use of natural gas and other fossil fuels by the industrial sector leads to production great quantities pollutants, including CO 2 , SO NO x . Consequently, these gases increase temperature earth, producing global warming. Different strategies have been developed help overcome this problem, utilization separation membrane technology. Mixed matrix membranes (MMMs) are hybr...

In this study polyethersulfone ultrafiltration membrane were prepared with the modifier gelatin at 0, 5, 10, 15 and 20 wt % using DMF as solvent by phase inversion process. Morphologies and characteristics of the membranes were investigated through the methods of SEM, XRD, contact angle measurements. The performance of the modified membrane for the treatment of leather and distillery wastewater...

This work presented an endeavour to fabricate sustainable and eco-friendly polyethersulfone (PES) ultrafiltration membranes. A novel graft copolymer (Poly(Maleic Anhydride-Co-Glycerol)) (PMG) have been synthesized via a facile rapid route impart their hydrophilic features onto the final PES membrane. series of characterization tools, for both nanoadditives nanocomposite membranes, harnessed con...

The inducible protein p71/73 marks the response of mouse macrophages to one of several stimuli (e.g., bacterial lipopolysaccharide or poly I:C) that trigger the expression of cytolytic activity when these cells have previously been primed for tumor cell killing by interferon-gamma (IFN-gamma). The results reported here identify this marker protein as the inducible prostaglandin endoperoxide syn...

The (secondary) electron emission from multilayered Al$_2$O$_3$/TiN membranes has been investigated with a hemispherical collector system in scanning microscope for electrons energies between 0.3 and 10 keV. These ultra-thin are designed to function as transmission dynodes novel vacuum multipliers. Two different types, bi-layer tri-layer, have manufactured by means of atomic-layer deposition (A...

Abstract Heavy metals (HMs) are highly toxic water pollutants abundant in industrial wastewater. Herein, a bis[3-(trimethoxysilyl)propyl]amine (BTMSPA) cross-linked multiwalled carbon nanotube (MWCNT) nanomaterial (CQACNT) was synthesized by silanization of MWCNT-OH followed grafting positively charged quaternary ammonium groups (glycidyl trimethyl chloride (GTMAC)) an epoxide ring-opening reac...

Biorelevant dissolution is an indispensable tool utilized during formulation development and optimization for the prediction of in vivo bioavailability of pharmaceutical agents. Within that framework, membrane-permeation dissolution methodologies are widely used to model drug absorption. The current work evaluates polymer membrane surface modifications for production of biomimetic membranes to ...

One of the polymeric membranes' main limitations is their susceptibility to fouling, lowering membrane's performance with time. Therefore, incorporating nanomaterials in polymer matrices has attracted great attention wastewater treatment applications. It's a promising approach for enhancing membrane hydrophilicity and performance. Herein, ultrafiltration nanocomposite membranes were synthesized...
