Size-monodisperse metal nanoparticles.....

Size-monodisperse pure copper particles are formed from metal salt precursors in a spray pyrolysis process that uses ethanol as co-solvent, thus avoiding the addition of hydrogen or other reducing gases. In addition, the uniform-size particles could be "classified" using a droplet impactor plate, which eliminates larger droplets at the atomizer prior to entering the reactor furnace (S.H. Ehrman et al., April 2; Adv. Mater. 2002, 14, 518-521)
