This paper aims to present a brief overview of different biosynthesis routes silver nanoparticles (NPs), their applications and influence the method used on size morphology these nanoparticles. A detailed comprehensive study available biological methods, also referred as bottom-up approach, well techniques reported, have been provided with an eye for details comparison between involving fungi, bacteria, algae plant extracts. Plant-derived bioreductants such leaf, stem or root extracts...
Cleaning wastewater containing low concentrations of phenolic compounds is a challenging task. In this work, agar-alginate beads impregnated with trihexyltetradecylphosphonium bromide ([P66614][Br]) ionic liquid adsorbent were synthesized as potential for such applications. FTIR, TGA, SEM, EDX and PZC studies performed to characterize understand the physicochemical properties adsorbent. The Fourier transformation infrared spectroscopy (FTIR) study showed that [P66614][Br] was effectively...
Polytetrafluoroethylene (PTFE) supported proton conductive membranes have become very attractive materials for portable electrochemical applications. In this study, we evaluate two-dimensional titanium carbide (Ti <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> C xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> T xmlns:xlink="http://www.w3.org/1999/xlink">x</inf> ) – MXene, to prepare PTFE exchange membranes.

Methylene blue (MB), an organic thiazine dye, has numerous industrial and medical applications. However, MB is a wastewater contaminant that harmful to humans aquatic life. Hence, its removal from water bodies essential. In this work, five novel deep eutectic solvents (DESs) were synthesized using different precursors, screened, studied for the extraction of methylene (MB) aqueous solution liquid–liquid extraction. The first, TOP-SA, was trioctylphosphine (TOP) as hydrogen bond acceptor...

Alizarin dye is toxic and has a negative influence on human life the environment. Consequently, scientific community faces difficult issue in developing efficient approaches for removing alizarin from water streams. Six distinct deep eutectic solvents (DESs) containing different hydrogen bond acceptors (HBAs), namely trioctylphosphine, trioctylamine trihexylamine, two donors (HBDs), salicylic acid malonic acid, were used to rapidly remove high concentration solutions up 2000 mg/L at room...
Fuel cells are preferred to operate at high temperatures, i.e., more than 100°C, due their numerous advantages, that range from improved kinetics and better water management. Unfortunately, Nafion cannot above 80°C as it dehydrates, so its proton conductivity decreases significantly. Therefore, in this work, a new polymer electrolyte membrane is developed. It based on solid conductors-Zirconium phytate (ZrPA) Silicotungstic acid. Ionic liquids used structure-directing agents....
Chitosan based membranes were fabricated in this work. Ionic liquids (ILs), namely, 1-Hexyl-3-methylimidazolium tricyanomethanide [HMIM] [TCM], Diethylmethylammonium methanesulfonate [DEMA] [OMs], used to modify the chitosan. The assessed for their potential application proton exchange membrane (PEMs) fuel cells. is one of attractive choices polymer materials because its reasonable conductivity and stability. synthesized by solution casting method followed a solvent drying procedure. These...
