Richard D Smith: Method of making supercritical fluid molecular spray films, powder and fibers. Battelle Memorial Institute, Marger & Johnson, March 29, 1988: US04734227 (138 worldwide citation)

Solid films are deposited, or fine powders formed, by dissolving a solid material into a supercritical fluid solution at an elevated pressure and then rapidly expanding the solution through a heated nozzle having a short orifice into a region of relatively low pressure. This produces a molecular spr ...
