This first report documents the quality of GCMs as a tool for describing and predicting ‘global warming’ and the related geographical pattern of climate change from the CO2 added to Earth’s atmosphere.

Sulfidation of silver nanoparticles: natural antidote to their toxicity.

Nanomaterials are highly dynamic in biological and environmental media. A critical need for advancing environmental health and safety research for nanomaterials is to identify physical and chemical transformations that affect the nanomaterial properties and their toxicity. Silver nanoparticles, one of the most toxic and well-studied nanomaterials, readily react with sulfide to form Ag(0)/Ag2S c...
