A simple one-step rapid green microwave irradiation method is described for the synthesis of silver nanospheres (Ag NS) using threonine as a reducing and polyvinyl-pyrrolidone as a capping agent. UV-Visible spectrum and photoluminescence spectrum confirmed the formation of Ag NS. High-resolution transmission electron microscopy and high-resolution scanning electron microscopy was used to find the morphology of the synthesized sample, which has sphere-like morphology. The elemental composition of the Ag NS was determined by energy dispersive X-ray analysis. Antibacterial experiments showed that the prepared Ag NS had better antibacterial activities than silver nitrate in the same concentration.read more

Shape-Controlled Synthesis of Gold and Silver Nanoparticles
Yugang Sun,Younan Xia +1 more
TL;DR: Monodisperse samples of silver nanocubes were synthesized in large quantities by reducing silver nitrate with ethylene glycol in the presence of poly(vinyl pyrrolidone) (PVP), characterized by a slightly truncated shape bounded by {100, {110}, and {111} facets.

Monodisperse FePt Nanoparticles and Ferromagnetic FePt Nanocrystal Superlattices
TL;DR: Thermal annealing converts the internal particle structure from a chemically disordered face- centered cubic phase to the chemically ordered face-centered tetragonal phase and transforms the nanoparticle superlattices into ferromagnetic nanocrystal assemblies that can support high-density magnetization reversal transitions.
