The Effect of the Anisotropic Nanoparticles Nature on the Properties of Ring Deposits Resulting from Evaporation of Droplets of Their Dispersions.

A comparative analysis has been performed for the structure of ring deposits resulting from the evaporation of droplets of aqueous dispersions of gold nanorods and composite nanoparticles with a gold core/organosilica shell structure based thereon. The nature of the particles has been shown to have a key effect on the character of their packing near a three-phase contact line. The study of the conductivity of the ring deposits obtained from dispersions of the composite particles has shown that it is realized via over-barrier electron emission. [ABSTRACT FROM AUTHOR]
