US Patent 7582328 Dropwise deposition of a patterned oxide superconductor

An oxide superconductor article having an oxide superconductor layer of a predetermined pattern is prepared by continuously advancing a wire having a textured surface into a deposition zone, dispensing droplets of a precursor solution to an oxide superconductor from a reservoir and the depositing droplets onto the textured surface of the wire that is introduced into the deposition zone, heating the wire or tape in the reaction zone under conditions to convert the precursor solution into an oxide superconductor; and collecting the wire after heating.
