Abstract: Nanoscale patterns prepared by lithography are used to direct the self-assembly of amphiphilic molecules to form patterned nanosubstrates having a desired distribution of chemical functional moieties. These patterns can be fabricated over a large area and require no special limitations on the chemistry the assembled amphiphiles. Hydrophilic/hydrophobic patterns can be created and used to direct the deposition of a single functional component to specific regions of the surface or to selectively assemble polymer blends to desired sites in a one step fashion with high specificity and selectivity. The selective deposition of functional moieties on a patterned surface can be based on electrostatic forces, hydrogen bonding, or hydrophobic interactions.

Abstract: A method of electrophotographic color reproduction by forming sequentially superimposed toner images of each color successively on the photoconductive surface of an electrophotographic recording member. The photoconductive surface is charged uniformly by a corona generator to a predetermined charge level. The charged surface is exposed to a first color radiation pattern from a source thereof to form a latent electrostatic charge image on said surface. The resulting latent charge image is toned with one color toner to produce a first toner image. The resulting toner image is dried. Thereafter, a charge is applied uniformly to the same photoconductive surface including those portions thereof carrying the dried first toner image in a manner so that the generated charged ions effectively tunnel through the dry adjacent toner particles defining first toner image to reach the photoconductive surface.
