A high flux thin-film nanocomposite membrane epoxy/ zeolite NaA nanocomposite films prepared by using ultrasonic mixing and spin coating. The synthesized nanocomposites film was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), thermal gravity analysis (TGA), and FTIR spectroscopy. Water softener and water flux characteristics of the epoxy/ zeolite NaA nanocomposite ...

Nanocomposite materials containing metal nanoparticles are of considerable interest in photonics and optoelectronics applications. However, device fabrication of such materials always encounters the challenge of incorporation of preformed nanoparticles into photoresist materials. As a solution to this problem, an easy new method of fabricating silver nanocomposites by an in situ reduction of pr...

Background The treatment of bacterial diseases has become an increase public health problem, since the conventional antimicrobial substances lose their effectiveness due to the microbial resistance phenomenon [1]. Silver is a metal with potential antibacterial activity, and showed significant efficacy against several species of bacteria. The silver activity to prevent microbial growth is enhanc...

in this scientific research, for the first time, the removal of radioactive strontium-90 (90sr) by γ-mno2-aga zeolite as a novel nanocomposite adsorbent was accomplished under different conditions such as ph, temperature, adsorbent amount and the contact time that are examined from drinking water of ramsar city and monitored via ultra low-level liquid scintillation counting (lsc) technique. pri...

We have studied the surface-smoothing effect of an ultrathin germanium (Ge) layer on silver (Ag)-silica (SiO2) nanocomposite films for superlensing applications. Our experimental results indicate that inserting a thin Ge layer below the silver-silica composite films can reduce the final surface root-mean-squared (RMS) roughness to under 1 nm. Additionally, the metal nanostructure plays a role i...

BACKGROUND Methicillin-resistant Staphylococcus aureus (MRSA) has been responsible for serious hospital infections worldwide. Nanomaterials are an alternative to conventional antibiotic compounds, because bacteria are unlikely to develop microbial resistance against nanomaterials. In the past decade, graphene oxide (GO) has emerged as a material that is often used to support and stabilize silve...

in this work, hydrogel nanocomposites were synthesized by solution polymerization of acrylic acid (aa) and itaconic acid (ia) in the presence of cotton fabric. ammonium persulfate (aps) was used as the polymerization initiator in the presence of a crosslinker, methylene bisacrylamide (mba). insertion of ag followed by reduction of ag+ cations results in a hydrogel nanocomposite. the structure a...

A silver-acrylate nanocomposite was prepared using a novel one-pot strategy involving eosin dye as visible sensitizer and an amine derivative as radicals source. The mechanism highlighted by steady state photolysis and time resolved absorption spectroscopy lies on the initial formation of a strong ion pair complex between eosin and Ag + . Upon visible irradiation, the excited triplet state of t...

The present paper describes the preparation and characterization of Polyvinyl Alcohol-Polypyrrole-Silver Nanocomposite (PVA-PPy-Ag NC) films. The prepared films were conducting, freestanding, flexible, and robust. Silver nanoparticles (Ag NPs) were synthesized from an aqueous solution of silver nitrate using trisodium citrate as a reductant. The casting solution for the films was prepared by in...

The purpose of this study was to investigate the antimicrobial properties of multifunctional nanocomposites based on poly(dl-Lactide-co-Glycolide) (PLGA) and increasing concentration of silver (Ag) nanoparticles and their effects on cell viability for biomedical applications. PLGA nanocomposite films, produced by solvent casting with 1 wt%, 3 wt% and 7 wt% of Ag nanoparticles were investigated ...
