TL;DR: The impact of capping agents and environmental conditions (pH, ionic strength, and background electrolytes) on surface charge and aggregation potential of silver nanoparticles (AgNPs) suspensions were investigated.

TL;DR: The results presented herein suggest that surface charge is one of the most important factors that govern the toxicity of AgNPs.

TL;DR: The antibacterial property of bulk silver is expected to be carried over and perhaps enhanced, to silver nanoparticles, and when one examines the environmental issues associated with the manufacture and use of silver nanoparticle-based products, the antibacterial effects should always be taken into account.

TL;DR: In the summer of 1994, a field study was undertaken in Delaware in which light crude oil was intentionally released onto plots to evaluate bioremediation as mentioned in this paper, and three treatments were evaluated: a no-nutrient addition control, adding of water-soluble nutrients, and addition of water soluble nutrients supplemented with a natural microbial inoculum from the site.

TL;DR: In this paper, the photocatalytic activities of sol-gel derived TiO2 films were studied utilizing a quartz batch reactor and the results showed that the films on the glass beads possessed better mechanical properties than the commercial catalyst beads and their activity can be significantly improved by optimizing the film synthesis process parameters.
