Gold Nanoparticles in solution

Research Interests

Similar to AuNP-stained Roman glass, incredibly low Au-loaded glaze formulations can be designed that should provide a range of colors at concentrations of metal two to three orders of magnitude below normal requirements. Due to nanomaterial research and these optical property-size relationships being only recently characterized, the fusion of nanomaterial and glaze formulation technologies has not yet been realized. The challenge is to create a system in which nanomaterial structures are formed during a reduction firing and remain stable up through 2345 ºF.

Just prior to finishing my doctoral work, I successfully prepared and fired a gold nanoparticle glaze that was rose-red in color, which has not yet been characterized. To that end, I plan to further explore this glaze formulation, seeking out blue and purple colors as a function of Au nanoparticle size. We are currently developing nanoparticle size-based colors with gold, silver, aluminum, copper, iron, and cobalt systems.

Research Topics
Noble metal nanoparticle emulsions in ceramic glazes for optical glaze color effects; formation of nanoscale nucleation sites in reduction atmosphere ceramic firing; use of ultra low loading inorganic nanomaterials for alternative glaze colorant systems (pic at right ); noble metal nanoparticle synthesis for biomimetic catalytic activity; amino acid substitution for inorganic surface recognition and control; bio-mimetic inorganic nanomaterial synthesis for green catalysis applications.
