A process for manufacturing a film or coating, the process comprising: a. producing an electrostatically charged plume comprising a plurality of particles and/or droplets, the particles and/or droplets comprising an additive and a liquid medium, by: i. providing a fluid stock to a first inlet of a first conduit of an electrospray nozzle, the first conduit being enclosed along the length of the conduit by a first wall having an interior surface and an exterior surface, the first conduit having a first outlet and a first outer diameter, and the fluid stock comprising the liquid medium and the additive; ii. providing an alternating current voltage to the nozzle, thereby providing an electric field at the first outlet of the first conduit of the nozzle; and iii. providing a pressurized gas to a second inlet of a second conduit of the nozzle, thereby providing high velocity gas at a second outlet of the second conduit, the high velocity gas having a velocity of about 50 m/s or more, the second conduit being enclosed along the length of the conduit by a second wall having an interior surface and an exterior surface, the second conduit having a second inlet and a second outlet, the second conduit having a second outer diameter, wherein at least a portion of the first conduit is positioned inside the second conduit, the exterior surface of the first wall and the interior surface of the second wall being separated by a conduit gap, with the first outlet protruding beyond the second outlet by a protrusion length, or, with the first outlet not protruding beyond the second outlet such that there is no protrusion length; and b. collecting a thin layer deposition on a substrate, the thin layer deposition having a thickness of 1 micron to 1 mm. a. producing an electrostatically charged plume comprising a plurality of particles and/or droplets, the particles and/or droplets comprising an additive and a liquid medium, by: i. providing a fluid stock to a first inlet of a first conduit of an electrospray nozzle, the first conduit being enclosed along the length of the conduit by a first wall having an interior surface and an exterior surface, the first conduit having a first outlet and a first outer diameter, and the fluid stock comprising the liquid medium and the additive; ii. providing an alternating current voltage to the nozzle, thereby providing an electric field at the first outlet of the first conduit of the nozzle; and iii. providing a pressurized gas to a second inlet of a second conduit of the nozzle, thereby providing high velocity gas at a second outlet of the second conduit, the high velocity gas having a velocity of about 50 m/s or more, the second conduit being enclosed along the length of the conduit by a second wall having an interior surface and an exterior surface, the second conduit having a second inlet and a second outlet, the second conduit having a second outer diameter, wherein at least a portion of the first conduit is positioned inside the second conduit, the exterior surface of the first wall and the interior surface of the second wall being separated by a conduit gap, with the first outlet protruding beyond the second outlet by a protrusion length, or, with the first outlet not protruding beyond the second outlet such that there is no protrusion length; and i. providing a fluid stock to a first inlet of a first conduit of an electrospray nozzle, the first conduit being enclosed along the length of the conduit by a first wall having an interior surface and an exterior surface, the first conduit having a first outlet and a first outer diameter, and the fluid stock comprising the liquid medium and the additive; ii. providing an alternating current voltage to the nozzle, thereby providing an electric field at the first outlet of the first conduit of the nozzle; and iii. providing a pressurized gas to a second inlet of a second conduit of the nozzle, thereby providing high velocity gas at a second outlet of the second conduit, the high velocity gas having a velocity of about 50 m/s or more, the second conduit being enclosed along the length of the conduit by a second wall having an interior surface and an exterior surface, the second conduit having a second inlet and a second outlet, the second conduit having a second outer diameter, wherein at least a portion of the first conduit is positioned inside the second conduit, the exterior surface of the first wall and the interior surface of the second wall being separated by a conduit gap, with the first outlet protruding beyond the second outlet by a protrusion length, or, with the first outlet not protruding beyond the second outlet such that there is no protrusion length; and b. collecting a thin layer deposition on a substrate, the thin layer deposition having a thickness of 1 micron to 1 mm.
