Extraterrestrial iron sulfide is a major mineral reservoir of the cosmochemically and astrobiologically important elements iron and sulfur. Sulfur depletion on asteroids is a long-standing, yet unresolved phenomenon that is of fundamental importance for asteroid evolution and sulfur delivery to the Earth...

The fluorescent FITC embedded in the silica layer enables optical imaging while folic acid at the outermost surface enables cell targeting. The prospects for the future development of these materials principally include: 1. Prevention of aggregation and increase the colloidal stability for long-term ...
1). Each individual nZVI particle is recorded to contain a discrete 3–5 nm thick outermost layer (density contrast), which is attributed to be the presence of an oxide shell surrounding the Fe0 core. In addition dark mottles were recorded within the metallic cores which indicates that ...
The iron oxide NPs are accumulated around the reference electrode when held at a constant potential while gaining electrons. Subsequently, when the potential is scanned towards 1.5 V, the iron oxide NPs return into the solution and the measured current corresponds to their concentration on the su...
