Kinetics and Mechanisms of Nanosilver Oxysulfidation [PDF]

Environmental Science & Technology, 2011
Among the many new engineered nanomaterials, nanosilver is one of the highest priority cases for environmental risk assessment. Recent analysis of field samples from water treatment facilities suggests that silver is converted to silver sulfide, whose very low solubility may limit the bioavailability and adverse impact of silver in the environment.

Utilization of triangle nanosilver to prepare spherical nanosilver and quantitatively detect trace titanium by SERS [PDF]

Nanoscale Research Letters, 2014
Abstract The blue triangle nanosilver (BAgNP) sol was prepared by the two reducers of NaBH4 and H2O2. Using BAgNP as the precursor, a small spherical nanosilver (AgNP) sol in yellow was synthesized by addition of suitable amounts of X − (X = Cl, Br, and I).

An environmentally benign antimicrobial nanoparticle based on a silver-infused lignin core [PDF]

, 2015
Silver nanoparticles have antibacterial properties, but their use has been a cause for concern because they persist in the environment. Here, we show that lignin nanoparticles infused with silver ions and coated with a cationic polyelectrolyte layer form
