Abstract The growing global concern about heavy metal pollution in water systems arises from its severe impacts on living organisms, including toxicity and carcinogenic effects. Using nano‐sized materials such as oxides metal–oxide frameworks (MOFs) offers potential due to their large surface area functional groups. This study focuses enhancing the efficiency of cellulose acetate (CA) membranes by incorporating nano‐graphene oxide (NGO) a polyethylene glycol (PEG) layer inhibit bacterial...
Abstract The urge need for innovative integration between Electromagnetic Waves (EMWs) and nanotechnology offers exciting possibilities improving antimicrobial treatments to combat antibacterial resistant bacterial infections. This study explores how EMWs at range below 300 Hz can enhance the efficacy of Graphene Oxide Nanoparticles (GONPs) against Pseudomonas aeruginosa , a significant pathogen in antibiotic resistance. Hz, interact with cell membranes affect ion channels, permeability,...
Abstract In the next decades, some countries will suffer from water shortage because of increased population and percentage economic development. Accordingly, it is necessary to find alternative way solve this problem investigate Nanoscale graphene pieces known as quantum dots (GQDs) exhibit distinctive characteristics that render them intriguing contenders for an array novel uses. Cellulose acetate (CA) membranes were prepared CA powder, formamide, acetone with different concentrations...
Abstract This study seeks to advance the realm of 3D printing through exploration fabricating polymer matrix composite objects using recycled materials, with a particular emphasis on bolstering durability. Characterization was carried out by integrating polyurethane foam (PUF) residues into thermoplastic (TPU) composites at different concentrations (ranging from 3% 10% wt/wt), which are frequently employed in printing. The chemical functions were analyzed Fourier‐transform infrared...
Abstract Cellulose acetate (CA) membranes used in reverse osmosis (RO) desalination techniques often face fouling challenges. In this experimental study, the phase inversion method was employed to investigate incorporation of graphene oxide nanoparticles (GONP) metal–organic frameworks (MOF), into casting solution for composite CA‐RO membranes. The effects varying GONP concentrations on resistance and hydrophilicity were evaluated using scanning electron microscopy (SEM), contact angle...
Abstract Polyvinyl chloride (PVC) is one of the most important commercial plastics but it thermally unstable at processing temperatures. Therefore, heat stabilizers are widely used to safeguard by improving resistance PVC products high temperature. But them a highly toxic that can cause severe health issues in humans and harmful environment. In present study mixed calcium/zinc stearate stabilizer green Expandable graphite (EG) prepared via hydrothermal treatment using additives nontoxic,...
Abstract Cellulose diacetate (CDA) and triacetate (CTA) were derived from Egyptian cotton to fabricate reverse osmosis (RO) membranes. The Pphase inversion method was utilized for the production of CDA‐based Comprehensive characterization these membranes involved structural, morphologial, hydrophilic property analyses through techniques such as nuclear magnetic resonance (NMR), infrared spectroscopy, thermal gravimetric analysis (TGA), scanning electron microscopy (SEM), atomic force (AFM),...
Abstract BACKGROUND This study enhancing the corrosion resistance of mild steel (MS) by incorporating photo‐catalyst‐doped graphitic carbon nitride (g‐C₃N₄) nano‐sheets containing silver (Ag) and oxygen (O₂) into a solar light‐active photoelectrochemical anticorrosion paint with polyester (PE). The objective is to provide sacrificial anode protection through visible light activation. RESULTS developed forms uniform film on MS surface, effectively providing anodic under light....
