Interactions of silver and polystyrene nanoparticles with algae
Nanoparticles have various physicochemical properties attributed by their small dimensions. The global production of nanoparticles lead to a raised concern for their environmental impacts. Algae are of highly ecological importance functioning as primary pr ...
EPFL2015Silver Nanoparticle Effects on Stream Periphyton During Short-Term Exposures
Kristin Schirmer, Ahmed Tlili, Renata Behra
Silver nanoparticles (AgNP) are increasingly used as antimicrobials in consumer products. Subsequently released into aquatic environments, they are likely to come in contact with microbial communities like periphyton, which plays a key role as a primary pr ...
Amer Chemical Soc2015Critical influence of chloride ions on silver ion-mediated acute toxicity of silver nanoparticles to zebrafish embryos
Kristin Schirmer, Renata Behra
The toxicity of silver nanoparticles (AgNP) to aquatic organisms, including zebrafish (Danio rerio), has been demonstrated, but differing opinions exist on the contribution of the physical properties of the particles themselves and the free dissolved silve ...
Informa Healthcare2015Release and environmental impact of silver nanoparticles and conventional organic biocides from coated wooden facades
This study represents for the first time a comprehensive assessment of functionality and environmental impacts of metallic silver nanoparticles (Ag-NP) compared to conventional organic biocides. Four different transparent, hydrophobic coatings of wooden ou ...
Elsevier2014Rational development of an electron-rich platinum nanocatalyst for the oxidation of 5-hydroxymethylfurfural into 2,5-furandicarboxilic acid under mild conditions
Paul Joseph Dyson, Zhaofu Fei, Ning Yan, Georgios Savoglidis, Sviatlana Siankevich
Valorization of lignocellulosic biomass for the production of commodity chemicals using various chemical methods continues to attract considerable attention. A wide and diverse range of different chemicals can be obtained from biomass and many different do ...
2013Photo-induced growth of silver nanoparticles using UV sensitivity of cellulose fibers
A simple method has been demonstrated to grow silver nanoparticles on the surface of cellulose fibers. The preparation is based on photo-activation of surface by ultraviolet (UV) photons, followed by chemical reduction of silver nitrate. It is found that t ...
Elsevier2012Magnetron-Sputtered Ag Surfaces. New Evidence for the Nature of the Ag Ions Intervening in Bacterial Inactivation
César Pulgarin, Juan Kiwi, Rosendo Sanjines
DC-magnetron sputtering with an Ag target on textile surfaces produced Ag particles with sizes similar to 4.7 nm (+/- 15%). Sputtering for 15 s led to Ag layers of 15-20 nm. The threshold sputtering time precluding airborne bacterial growth was about 60 s. ...
2010Intense X-ray induced formation of silver nanoparticles stabilized by biocompatible polymers
Colloidal Ag nanoparticles were formed by X-ray irradiation in the presence of a polymer. This new synthesis method is simple, rapid and leads to a high production yield. Compared to the citrate-reduced Ag colloidal, polymer-protected Ag nanoparticles are ...
2009Controlled Reversible Adsorption of Core-Shell Metallic Nanoparticles at the Polarized Water/1,2-Dichloroethane Interface Investigated by Optical Second-Harmonic Generation
Hubert Girault, Christophe Bauer, Pierre-François Marie Brevet, Jean-Pierre Abid
We report the observation of the reversible adsorption of core-shell gold-silver nanoparticles at the polarized water/1,2-dichloroethane interface using the nonlinear optical technique of surface second-harmonic generation. This study unambiguously demonst ...
2007Ag-doped carbon aerogels for removing halide ions in water treatment
The objective of this study was to analyze the efficiency of silver(Ag)-doped carbon aerogels for the removal of bromide (Br-) and iodide (I-) from drinking waters. Textural characterization of Ag-doped aerogels showed that an increase in the Ag dose added ...
