Abstract Shortage of drinking water has gained potential interest over the last few decades. Discharged industrial effluent, including various toxic pollutants, to surfaces is one most serious environmental issues. The adsorption technique become a widely studied method for removal specifically synthetic dyes, from wastewater due its cost-effectiveness, high selectivity, and ease operation. In this study, novel gelatin-crosslinked-poly(acrylamide- co -itaconic acid)/montmorillonite (MMT)...
Nanotechnology is one of the most emerging fields in recent years. In current investigation, we report biosynthesis iron nanoparticles (Fe-NPs) employing Alternaria alternata fungus, which an eco-friendly process for synthesis metallic nanoparticles. Fe-NPs were synthesized through reduction aqueous Fe3+ ion dark conditions. Ultraviolet–visible spectrum medium containing ion showed a peak at 238 nm and another 265 nm. The forming was confirmed by transmission...
Batch RO desalination is a new approach to high-recovery, energy-efficient desalination. So far, however, batch has been tested mostly with pure sodium chloride solutions. An important application of brackish groundwater which, besides chloride, contains sparingly soluble salts. In this experimental study system, we used simulated (with total dissolved solids ranging from 1180 3637 mg/L) following compositions samples taken location in Egypt and India. The contained high levels salts which...
In this work, plasmonic Ag/AgX/rGO (X = Cl or Br) nano‐photocatalysts were grafted with silicon by adding trimethylsilyl chloride as precursor. The synthesized Ag/AgX/rGO‐Si hybrids showed a large improvement of photocatalytic activity towards the synthesis p‐aminophenol (PAP) well paracetamol (acetaminophen; APAP) through photoreduction p‐nitrophenol (PNP). prepared catalysts characterized using SEM, XRD, FTIR and reduction reaction was monitored UV–Vis measurements, GC/MS 1 HNMR data. From...
Domestic dogs and cats can be a source of human infection by wide diversity zoonotic pathogens including parasites. Genotyping subtyping tools are useful in assessing the true public health relevance canine feline infections these pathogens. This study investigated occurrence, genetic diversity, potential common diarrhea-causing enteric protist parasites household Egypt, country where this information is particularly scarce.In prospective, cross-sectional total 352 individual fecal samples...
The design of reactors based on high performance photocatalysts is an important research in catalytic hydrogenation. In this work, modification titanium dioxide nanoparticles (TiO
The valorization of nitrous oxide (N2O) as an oxygen atom donor presents attractive opportunity for green chemistry applications, leveraging both its industrial abundance and thermodynamically favorable oxidation potential. However, practical implementation has been constrained by the inherent kinetic inertness poor coordinating ability N2O. While prior studies achieved N2O-mediated conversion aryl halides to phenols, such transformations necessitated stoichiometric chemical reductants...
Abstract In this work, a simple and greener protocol for the synthesis of 1‐substituted 1 H ‐tetrazole derived from α ‐amino acid ethyl esters was demonstrated in presence zinc oxide nanoparticles (ZnO NPs) under conventional conditions, with heating (at 60 80°C reflux) compared ultrasonic. The effect solvent investigated to reveal that system CH 3 CN/H 2 O optimum obtain high yield. addition, irradiation power studied, which showed yield reaction improved at 200 W time shortened be 30 min....
Irradiation of a series aromatic epoxides and CO2 in the presence TiO2, TiO2/MWCNT, Pt//TiO2/MWCNT Pd/TiO2/MWCNT photocatalysts was investigated with visible light-induced cycloaddition reactions for production cyclic carbonates high activity selectivity. The catalytic order these catalysts revealed as follows: > TiO2/MWCNT TiO2. main features this protocol are transformation to at ambient temperature under atmospheric pressure. band gap energies Pt/TiO2/MWCNT nanocomposites were estimated...
Novel gold nanoparticles capped by yeast extract, showing highly effective cytotoxicity towards cancer cells under visible light.
Ultra-pure water, free from metals and micro-organisms, has been easy obtained Red seawater (Jeddah, KSA) by plasmonic-graphene hybrid nanocomposites that green synthesized using Baker's yeast (Saccharomyces cerevisiae) extract under visible light irradiation. Gas chromatography mass spectroscopy (GC/MS) analysis of aqueous indicates the presence significant biomolecules; butane-2,3-diol, glucose, undecanoic acid, indole-3-acetic acid can act as reducing capping agent for growth (Ag, Au,...
