Abstract: A method of measuring a minimum pressure for gas bubble generation (MPGBG) value of a capillary tube is disclosed. The capillary tube has an inlet and an output portion including an outlet. The inlet is connected to a regulated pneumatic system, configured to supply a gas to the inlet under pressure. The output portion is immersed in a liquid. The gas is supplied to the inlet under a range of pressures including a higher pressure range and a lower pressure range. In the higher pressure range, gas bubbles are generated in the liquid from the outlet. In the lower pressure range, no gas bubbles are generated in the liquid from the outlet. A value of the minimum pressure for gas bubble generation (MPGBG) for the liquid is determined.
Other methods include a method of measuring and storing MPGBG values of capillary tubes, methods of selecting at least one capillary tube from a plurality of capillary tubes, and a method of cutting a capillary tube to a desired MPGBG value.

Abstract: Methods are disclosed relating to the operation of a micro-structural fluid ejector in a fluid printing apparatus. The methods include providing an imaging system, capturing a digital image of the micro-structural fluid ejector and its surroundings, and pre-processing the digital image to detect edges. A method of detecting contact of a micro-structural fluid ejector to a substrate includes repeatedly lowering the print head and measuring the length of a detected edge until the currently measured length is determined to be longer than a previously measured length. A method of adjusting contact of a micro-structural fluid ejector to a substrate includes calculating a bending coefficient A of the micro-structural fluid ejector and lowering the print head toward the substrate if the bending coefficient A is less than a minimum threshold value Amin, raising the print head away from the substrate if the bending coefficient A is greater than a maximum threshold value Amax, and making no change to the vertical displacement of the print head if the bending coefficient A is in the range of Amin to Amax. A method of detecting a fault condition in fluid flow from a micro-structural fluid ejector onto a substrate includes analyzing the digital image to determine whether edges are present in a region of interest where fluid dispensed from the micro-structural fluid ejector should be present.

Abstract: An additive method of forming a metallic nanoparticle microdot on a substrate is disclosed. The method includes: (A) estimating or obtaining a position of an outlet of a capillary tube at zero height above the substrate (zero-height position); (B) extruding a metallic nanoparticle composition from the outlet at a first height h1 above the zero-height position, including forming a fluid bridge between the outlet and the substrate; (C) optionally lifting the capillary tube relative to the substrate by a height increment of Dh while continuing to extrude the metallic nanoparticle composition from the outlet; and (D) rapidly lifting the capillary tube to separate the outlet from the fluid bridge.

Abstract: A method of decreasing a sheet resistance of a transparent conductor is disclosed. The method includes the following: forming a first transparent conductor layer on a substrate; dispensing a metallic nanoparticle composition on the first transparent conductor layer to form metallic nanoparticle features; and sintering at least the first transparent conductor layer and the metallic nanoparticle features. The first transparent conductor layer includes a crystalline metal oxide. The aperture ratio of the transparent conductor is in a range of 90% to 99%.
A multilayer transparent conductor and a method of forming a multilayer transparent conductor are also disclosed.

Abstract: Fluid printing apparatus including substrate, print head, pneumatic system, and print head positioning system. The print head ejects fluid in a continuous stream with a micro-structural fluid ejector consisting of output, elongate input, and tapering portions between the output and elongate input portions. The output portion consists of an exit orifice of an inner diameter ranging between 0.1 μm and 5 μm and an end face having a surface roughness of less than 0.1 μm. The print head is positioned above the substrate with the output portion of the micro-structural fluid ejector pointing downward. During printing, the print head positioning system maintains a vertical distance between the end face and the printable surface of the substrate within a range of 0 μm to 5 μm, and the pneumatic system applies pressure to the fluid in the micro-structural fluid ejector in the range of −50,000 Pa to 1,000,000 Pa.

Abstract: A method of obtaining a numerical model is disclosed. The numerical model correlates estimated line width values to minimum pressure for gas bubble generation (MPGBG) values. An MPGBG value of each capillary tube in the reference group is measured for a liquid. A nanoparticle composition is deposited, under standard conditions, on substrate(s) from each respective reference capillary tube, to form nanoparticle lines. A line width of each of the nanoparticle lines deposited using each respective reference capillary tube is measured by a microscope apparatus. A numerical model that correlates estimated line width values to MPGBG values for the liquid is calculated.

Abstract: A method is provided for forming structures upon a substrate. The method comprises: depositing fluid onto a substrate so as to define a wetted region, the fluid containing electrically polahzable nanoparticles; applying an alternating electric field to the fluid on the region, using a first electrode and a second electrode, so that a plurality of the nanoparticles are assembled to form an elongate structure extending from the first electrode towards the second electrode; and removing the fluid such that the elongate structure remains upon the substrate.
