Abstract: The method utilises a conducting trench base with non-conducting trench walls to corral charged particles precisely into the trenches. The nanoparticles are close packed in the channels and highly ordered. This approach utilises the charge on the particles to selectively deposit them within the trenches, as all nanoparticles in solution can be charged, and this can be extended to any nanoparticle system beyond gold. Also, this method results in the layer-by-layer growth of the gold nanoparticles. Therefore the depth of the nanoparticle layers within the trenches is controllable. This allows the possibility of heterolayered structures of different nanoparticle layers. Further this method ensures that assembly occurs to fill the void space available provided the back-contacting electrode is more conducting than the trench walls.

Abstract: A “green process” and system employing a first operation of electrophoresis in a liquid suspending selected solids to introduce the suspended solid particles as micro- or nano-particles, or both, into pore spaces of a porous non-conductive medium. A second operation uses electro-transport to move ions of solids into small pore spaces inaccessible via electrophoresis alone to grow solids in these smaller pore spaces to a size that may fill them, thus increasing the density and strength of the medium. The process yields a material that has improved strength, reduced porosity, high density and, in select applications, resistance to formation of mildew, mold, fungus and the like. Certain applications also enable decorative colors and florescence to be introduced to the media. Materials made from the process include high strength concrete construction panels, “backer boards,” work surfaces, counter tops, complex decorative configurations, strong thin walled items, and the like.
