We do. Hydrogen peroxide and nano silver based Alstasan Silvox Hydrogen peroxide has been well known as eco-friendly sanitizer for its effective antimicrobial efficacy, usage flexibility, non-toxicity and biodegradability. Effective over a plethora of microorganisms, hydrogen peroxide works fast with excellent material compatibility and negligible toxicity, by breaking down into ...
The team of PNNL researchers has developed a silver nitrate powder and zirconyl nitrate-based catalyst capable of converting 70 percent of aqueous ethanol to butadiene in a single pass under industrially-relevant conditions. ...
Locally manufactured ceramic water filters are one effective household drinking water treatment technology. During manufacturing, silver nanoparticles or silver nitrate are applied to prevent microbiological growth within the filter and increase bacterial removal efficacy. ...
Removal of total cyanide was determined using the silver nitrate titration method. Regression analysis and optimization of the conditions were conducted using the Design-Expert software and response surface methodology (RSM). ...
To demonstrate applicability of the method for assessing the toxicity of chemical‐spiked sediment, H. azteca were exposed for 42 days to sediment amended with silver nitrate (AgNO3). The mortality of H. azteca was significantly higher at the highest sediment concentration of Ag (2088 mg/kg dry weight); however, there was no significant reduction of biomass or ...
The aim of the present study was to evaluate the effect of silver nanoparticles (AgNPs) on Enchytraeus crypticus, applying a combined toxicokinetics and toxicodynamics approach to understand the relationship between survival and the development of internal Ag concentrations in the animals over time. ...
Adult fathead minnows were exposed to silver nitrate (0.82 µg/L or 13.2 µg/L), polyvinylpyrrolidone‐coated silver nanoparticles (11.1 µg/L or 208 µg/L), and citrate‐coated silver nanoparticles (10.1 µg/L or 175 µg/L) for 96 h. ...
This study utilised spontaneous electrochemical reaction, which involves etching of silicon wafer in a silver nitrate and hydrofluoric acid based solution, to modify etching times for silicon nanowires fabrication. ...
The impact of silver nanoparticles (AgNP; at 0, 1.5, 15.4 and 154 mg Ag/kg soil) and silver nitrate (AgNO3; 15.4 mg Ag/kg soil) on earthworms, Lumbricus rubellus, was assessed. ...
With increasing use of silver nanoparticles (AgNPs), concerns on their potential deleterious effects on aquatic ecosystems have increased. Most previous studies have focused on toxicity of AgNPs while their bioavailability has been seldom investigated. The present study examined the effects of salinity on the aggregation kinetics as well as the bioavailability of commercial 80 nm citrate ...
The most persistent question regarding the toxicity of silver nanoparticles (AgNPs) is whether this toxicity is due to the nanoparticles themselves or the silver ions (Ag+) they release. The present study investigates the role of surface coating and the presence of dissolved organic carbon on the toxicity of AgNPs to Daphnia magna and tests the hypothesis that ...
Silver nitrate was as used silver source. 0.1, 0.5 and 1.0 mol% concentrations of silver sol were prepared with different amounts of silver nitrate. ...
As the production and applications of nano silver (nano Ag) increase, it is essential to characterize fate and effects in environmental systems. ...
Tests conducted in the new medium confirmed that nematodes reproduction was possible at a range of solution pHs, offering the potential to conduct toxicity studies under a range of conditions. A test to establish silver nanoparticle and dissolved silver nitrate toxicity, a study type not feasible in M9 or agar media due to precipitation and ...
When the AgNO3 concentration is large enough, the reflection coefficient of SiNW arrays is less than 2%.Keywords: silicon nanowires, silver nitrate, AgNO3, optical properties, absorption, reflection, nanotechnology, nanowire ...
The widespread use of silver nanoparticles (Ag‐NPs), for example, in textiles and cleaning products, means that they are likely to reach the environment via biosolids or the effluent from wastewater treatment plants. ...
More and more silver nanoparticles (AgNPs) have been released into the aquatic environment due to their widespread use, which may result in harmful effects on aquatic organisms. ...
The process employs the photoreduction of silver ions in a metal ion solution composed of silver nitrate (AgNO3) and water-soluble polymer (poly(4-styrenesulfonique acid)). To improve the resolution and the uniformity of metallic micropatterns, a metal ion solution with a high concentration of silver ions was used, and the ...
A key aspect of the manufacture of photographic emulsion is the formation and growth of silver halide crystals. This critical reaction between silver nitrate and halide is process sensitive, and requires close quality control of the chemical constituents. Pure water, used as a solvent, is a primary ingredient in producing the ...
Selenium volatilizes from soils when converted to volatile selenium compounds (e.g., dimethyl selenide) by microorganisms. Silver: Silver (Ag) occurs naturally and in ores such as argentite (Ag2S) and horn silver (AgCl). ...
