TLDR
It is suggested that Ag MNP coating does not need to be taken into account to understand fate of AgMNPs applied to soil through biosolids amendment, because pre-incubation with sewage sludge negated these effects.About:

TL;DR: This work provides a basis to determine outcomes of nanoceria in soil, at a dose close to predicted environmental concentrations, and to design them to minimize these impacts.

Effects of carbon nanotubes on physicochemical properties and sulfamethoxazole adsorption of sediments with or without aging processes
TL;DR: In this paper, the influence of multi-walled CNTs on sediment pore surface properties, hydrophobicity and the sulfamethoxazole (SMX) adsorption behavior were investigated.

in situ methods for monitoring silver nanoparticle sulfidation in simulated waters
John M. Pettibone,Jingyu Liu +1 more
TL;DR: By distinguishing Ag+ from individual AgNPs, quantification of each population becomes tractable, which is a critical measurement need for toxicity testing and predicting NP fate in engineered and natural systems.
Journal ArticleDOI
Ecotoxicity and fate of a silver nanomaterial in an outdoor lysimeter study
TL;DR: The results from the long term lysimeter experiments show no detectable horizontal displacement in combination with very low remobilization to the percolate water, indicating that the sludge applied AgNM remains nearly immobile in the pathway between soils and leachate.

Quantitative study of the capture of silver nanoparticles by several kinds of soils
R.A. González-Fuenzalida,Lorenzo Sanjuan-Navarro,Yolanda Moliner-Martínez,Pilar Campíns-Falcó +3 more
TL;DR: In-tube solid-phase microextraction coupled on-line to capillary liquid chromatography with diode array detection was employed for measuring the interactions between soil and in-contact AgNP dispersions and can be utilized for quickly assessing the potential of a given soil considering its properties for capturing these nanoparticles.

A study of the nucleation and growth processes in the synthesis of colloidal gold
TL;DR: In this paper, a preliminary survey with the electron microscope of various preparations of colloidal gold, a study was made of the process of nucleation and growth in gold colloids, and it was shown that nucleating agents may be identified with reducing agents which form a mixed polymer with chlorauric ion before the reduction to the nucleus takes place.
Journal ArticleDOI
Analysis of Macromolecular Polydispersity in Intensity Correlation Spectroscopy: The Method of Cumulants
TL;DR: The first order electric field correlation function of laser light scattered by polydisperse solutions of macromolecules can be written as a sum or distribution of exponentials, with decay rates proportional to the diffusion coefficients of the solute molecules as discussed by the authors.

Modeled Environmental Concentrations of Engineered Nanomaterials (TiO2, ZnO, Ag, CNT, Fullerenes) for Different Regions
TL;DR: The results of this study indicate that risks to aquatic organisms may currently emanate from nano- Ag, nano-TiO(2), and nano-ZnO in sewage treatment effluents for all considered regions and for nano-Ag in surface waters.

Nanoparticle Silver Released into Water from Commercially Available Sock Fabrics
Troy M. Benn,Paul Westerhoff +1 more
TL;DR: Variable leaching rates among sock types suggests that the sock manufacturing process may control the release of silver, and physical separation and ion selective electrode (ISE) analyses suggest that both colloidal and ionic silver leach from the socks.
