    Abstract: Electrodeposition involving an electrolyte having a surface-smoothing additive can result in self-healing, instead of self-amplification, of initial protuberant tips that give rise to roughness and/or dendrite formation on the substrate and/or film surface. For electrodeposition of a first conductive material (C1) on a substrate from one or more reactants in an electrolyte solution, the electrolyte solution is characterized by a surface-smoothing additive containing cations of a second conductive material (C2), wherein cations of C2 have an effective electrochemical reduction potential in the solution lower than that of the reactants.

    Abstract: The present invention is a method and apparatus for obtaining a suspension of fine particles. The method has the steps of incorporating a compound in a variable density fluid as a fluid premixture, discharging the fluid premixture through a nozzle into a receiving liquid and forming particles of the compound. For certain compounds, mixing a surfactant with the receiving liquid prevents and retards agglomeration of the particles, and heating the nozzle prevents the formation of ice. The compound is preferably a pharmaceutical, and a biocompatible supercritical solvent maximizes solubility of the compound in the premixture. Fine particles of the compound are produced by rapid expansion of the supercritical fluid premixture in the receiving liquid.

    Abstract: A method and apparatus for forming patterned coatings of thin film, non-polymerizable compounds on a substrate. A mixture of the non-polymerizable compound and a liquid carrier is pumped into the interior of a heated evaporation box having an internal temperature sufficient to convert substantially all of the non-polymerizable compound and liquid carrier to a gaseous form. The non-polymerizable compound and liquid carrier are then removed from the evaporation box via exit slit in the evaporation box. Adjacent to the exit slit, and maintained in a vacuum, is a first substrate upon which the non-polymerizable compound condenses. The first substrate is in motion, for example on a web roller, thereby allowing a continuous coating of the non-polymerizable compound to be applied to the first substrate. Once the non-polymerizable compound is applied to one side of the first substrate, an energy source is then directed toward the opposite side of the first substrate. In this manner, a portion of the non-polymerizable compound is removed from the first substrate. A second substrate is then provided adjacent to the first substrate, and the non-polymerizable compound is thereby transferred from the first substrate onto the second substrate. By repeatedly transferring portions of the non-polymerizable material from the first substrate to the second substrate in this manner, the thin film, non-polymerizable materials can be formed onto the second substrate in a predetermined pattern, and in a continuous and highly efficient process.
