Silver has long been known to have antimicrobial properties and were used until chemical antibiotics came into vogue. Metallic silver and most inorganic silver compounds ionize in moisture, body fluids and secretions to release biologically active Ag+, which the silver ions have been used for the characteristics of toxicology and pharmacology as antimicrobial agent.1 Nanosilver particles have b...

Self-etch adhesives that etch, prime, and bond simultaneously should not exhibit incomplete resin infiltration within hybrid layers. We hypothesized that nanoleakage patterns in these systems are artifacts caused by mineral dissolution in mildly acidic silver nitrate. Resin-dentin interfaces bonded with four single-step, self-etch adhesives were examined for nanoleakage by conventional (pH 4.2)...

The determination of silver nanoparticles (Ag NPs) with single-particle inductively coupled plasma mass spectrometry can be severely interfered coexisting dissolved causing high background signals, which lead to inaccurate quantification NP size and particle concentration. In this paper, chemically active reusable 3D printed scavengers are applied for highly efficient removal in Ag dispersions,...

background: today, issues such as water shortage, difficulties and costs related to supplying safe water, and anomalous concentrations of heavy metals in groundwater and surface water resources, doubled the necessity of access to technical methods on removing these pollutants from water resources. methods: in this lab study, cationic resin purolite s-930 (with co-polymer styrene di-vinyl benzen...

  Background & objective: Mercury is a toxic and bio-accumulative pollutant that has adverse effects on environmental and human health. There have been a number of attempts to regulate mercury emissions tothe atmosphere. Silver nanoparticles are a number of materials that have highly potential to absorb mercury and formation of mercury amalgam.The aim of this study is removal of mercury va...

Here ther is an on effort to improve working electrode (Ag + CNTs) preparation for Li-Ion batteries applications. Nano scaled silver foam with high specific area has been employed as a frame for loading CNTs by EPD method. In this ground, the prepared electrodes show a very good stability and also charge-discharge cycles reversibility.

Mesostructured 2d-hexagonal sol-gel films were prepared by dip-coating method. Their structures were detected by X-ray diffraction. Silver nanoparticles reduced from Ag ion (silver nitrate) to Ag were deposited into the channels of the structure produced by the neutral surfactant Brij58. Surface enhanced raman spectroscopy technique was used to characterize the films. Spectra of films without m...

Long-term changes in species of copper-silver bimetallic systems on natural clinoptilolite obtained by ion exchange Cu2+ and Ag+ then reduced at different temperatures were studied. Even after storage under ambient conditions, XRD UV-Vis diffuse reflectance spectra indicate the presence nanospecies larger particles copper silver. Scanning electron microscopy aged samples, highest temperature (4...

Formation of silver citrate/citric acid complexed solutions was investigated. Although, silver citrate is minimally soluble in water, it can successfully be dissolved in citric acid solutions. The maximum concentration of Ag(I) in solution is estimated at 23 to 25 g/L if the concentration of citric acid is at least 4 mol/L or higher. The dissolution of silver citrate in citric acid solutions wa...

• Ag@PPy composite nanofibers were successfully synthesized by one-step method without additional oxidant. composites exhibit adsorption capacity of 7.02 mg/g for fluoride and fast kinetics within 60 min. High density 3.27 g/cm 3 makes the fine settlement performance from water. also show excellent bactericidal introduction silver. To facilitate separation properties polypyrrole (PPy) removal w...
