Abstract: An aerosol creation system can include a pair of counter-rotating rollers configured to be positioned adjacent each other and define a nip between each other, a fluid source configured to provide a fluid to the nip, a driving element configured to drive the pair of counter-rotating rollers to rotate in counter rotation with respect to each other and cause the fluid to be drawn through the nip, and a collection shell configured to be positioned substantially around the pair of counter-rotating rollers, the collection shell having a nozzle configured to allow passage of the fluid from the nip.

Abstract: A system to electrohydrodynamically pattern a material includes a first electrode having a first voltage, a second electrode having a second voltage that is different from the first voltage, one or more materials to be patterned residing between the first electrode and the second electrode, a gap between at least one surface of at least one of the materials to be patterned and one of the first or second electrodes, at least one patterning material in the gap, wherein the patterning material is a material other than air, and at least one filling material filling any remainder of the gap.

Abstract: A roller includes a cylindrical outer surface of a hydrophobic material, an inner core of a hydrophilic material, and an inhomogeneous geometric pattern of grooves in the surface that expose the hydrophilic material. A method of manufacturing a roller, includes providing a cylindrical core of a hydrophilic material, covering the cylindrical core with a hydrophobic surface, creating grooves in the hydrophobic surface to form a geometrically inhomogeneous pattern of the hydrophilic material. A method of manufacturing a roller, includes forming a pattern of geometrically inhomogeneous grooves on a hydrophobic core, functionalizing the surface to make the surface hydrophilic, and removing a portion of a top layer of the hydrophobic core to expose the hydrophobic core, leaving hydrophilic grooves.
