A variety of silver-based nanoparticles have been manufactured using several processingmethods.  The long-term goal of these nanoparticles is for their use in inks for printedelectronics applications.  Initial work has concentrated on control of particulate manufacturingtechniques, mainly with respect to size and shape.

Characterization of the nanoparticles has been performed using a suite of techniques scanningelectron microscopy, transmission electron microscopy, Raman spectroscopy and x-raydiffraction.

Traces of silver inks were made using the maskless, mesoscale material deposition (M3D).These lines were thermally cured after which the line conductivity was measured.  Atomic forcemicroscopy and differential scanning calorimetry were used to characterize the silver traces.
