Synthesis study of size-controlled noble metal nanoparticle systems of Re, Ir, and Os using AOT-reverse microemulsion based methodologies
… methodology for synthesizing stable, very small nanoparticles (NPs) of rhenium (Re), iridium (Ir), and osmium (Os) using a reverse microemulsion (AOT-ME) system, with AOT as the negatively charged surfactant to form and stabilize the MEs. These noble metals are among the least studied in their NP …
