Web lifter and/or stabilizer and method of lifting and/or stabilizing a travelling web and for coating a web. The device creates a web hold down force via a negative pressure slot at its exit side, which draws the web down against the surface on the entry side. The device can be actuated to move the web relative to a slot die coater off the die lips and stop the application of slurry to the web, thereby creating uncoated regions on the web surface. The device can then be actuated to move the web back into contact with the coater to start the application of slurry to the web, thereby creating coated regions on the web surface. Web lifting can be accomplished by rotating the device in first and second directions to lift the web off of the slot die coater and return the web back into contact with the coater.

Aspects herein are directed to systems, methods, and articles for producing a patterned film and using the patterned film to form a pattern of discrete overlay film structures on a substrate material. A uniform thickness of a film material is deposited on to a first surface of a run of carrier sheets, where each carrier sheet includes one or more holes extending there through. A first carrier sheet is extracted from the run of carrier sheets, and a second surface of the carrier sheet is positioned on a substrate material. Heat and/or pressure is applied to the film material to cause the film material to transfer to the substrate material through the one or more holes in the carrier sheet forming a pattern of discrete overlay film structures on the substrate material. The carrier sheet along with remaining portions of the film material is removed from the substrate material.

A coating device coats a to-be-coated object including a recessed portion extending in a first direction. The coating device includes a head, an arm, and a controller. The head includes a nozzle surface. The arm holds the head. The controller controls movement of the head via the arm. The controller moves the head in the first direction while causing the nozzle surface and the recessed portion to face each other in a posture in which a length of a first component along the first direction of the head is larger than a length of a second component of the head intersecting the first component.

According to various embodiments, a cover is sealed over a metasurface on a substrate to create a sealed chamber. Liquid crystal, or another tunable refractive index dielectric material, is positioned within the sealed chamber around optical structures of the metasurface before or after the cover is sealed. For example, the liquid crystal may be injected through small vias or holes to fill a sealed chamber. In some embodiments, a glass cover is shaped or patterned with photoresist to protrude into the sealed chamber to reduce the thickness of the liquid crystal used to fill the sealed chamber. A driver to control the metasurface may be, for example, integrated within the substrate, be attached to exposed bond pads of the metasurface, and/or be embodied as a control layer connected to the metasurface through the substrate by through-substrate vias (TSVs).

A small diameter roll is provided on the upstream side of a heating and sucking roll, an electrode slurry is applied by using a slot nozzle on the small diameter roll or an OFF roll, and an electrode is formed by instantaneously evaporating a solvent by the heating and sucking roll.

Fusing nanowire inks are described that can also comprise a hydrophilic polymer binder, such as a cellulose based binder. The fusing nanowire inks can be deposited onto a substrate surface and dried to drive the fusing process. Transparent conductive films can be formed with desirable properties.

Disclosed are an entrained polymer or an entrained polymer composition, and a method for forming and adhering an entrained polymer structure to a substrate using the entrained polymer or an entrained polymer composition. The method includes providing a substrate configured to receive application of a molten entrained polymer. A particulate entrained polymer in molten form is applied in a predetermined shape, to a surface of the substrate, to form a solidified entrained polymer structure on the substrate. The entrained polymer includes a monolithic material formed of at least abase polymer and a particulate active agent. The surface of the substrate is compatible with the molten entrained polymer so as to thermally bond with it. In this way, the entrained polymer bonds to the substrate and solidifies upon sufficient cooling of the entrained polymer.
