Abstract:
A method comprising providing a target material (115), providing a substrate (107), ablating the target material (115) to form ablated target particulate material (117), directing the ablated particulate material (117) toward the substrate (107) with a gas flow, and coating the substrate surface (107).
Abstract:
Coating materials comprising polymeric particles in a geometrically ordered array are disclosed. The particles can be formed from materials having different glass transition temperatures; this allows for phase segregation between areas of different glass transition temperatures within each particle. Typically, at least 50 percent of the particles will form a hexagonal array, capable of exhibiting Bragg diffraction. Because the particles within the array do not coalesce to any appreciable extent, significant surface area is provided by the present coating materials. Thus, the present materials have particularly good sound deadening properties. Substrates coated with the present materials are also disclosed, as are methods for inhibiting sound transmission through a substrate using these coatings.
Abstract:
A process is described to prepare monolayers of particles or molecules (3) comprising the steps of: injecting a liquid film (2) containing particles or molecules (3) dispersed therein on the external surface of a rotary member (1); adjusting the chemical characteristics of the particles or molecules (3), where such adjusting step carries the partides or molecules (3) to the surface of te thin liquid film (2); carrying the particles or molecules (3) absorbed at the gas-liquid interface of the thin liquid film (2) into a uniform monolayer (5); and transferring the monolayer (5) from the thin liquid film (2) surface to a solid substrate (7). Optionally, the step of working said uniform monolayer (5) is also present.
Abstract:
A method of forming a polymer layer on a support surface by the use of a coating agent and polymerizable compounds. The coating agent provides photoreactive groups adapted to attach the agent to the surface, as well as photoreactive groups adapted to remain unattached to the surface, and thus serve as photoinitiators for the activation of polymerizable compounds in order to form a polymer layer thereon. Also provided are coating agents, per se , as well as a method of using such agents and the resultant surfaces and devices fabricated therefrom.
Abstract:
A process and an apparatus are disclosed for coating at least one surface of an article such as a paper plate with a liquid coating. The surface to be coated is passed through a wave of liquid coating, such as an aqueous dispersion, followed by removal of the excess coating. The coating and coating removal steps are carried out in an environment which is vaporous with the vehicle of the liquid coating, which prevents premature drying of the coating and allows for a smooth, even application of the coating to the surface.
Abstract:
A substrate (5) is located within a deposition chamber (2), the substrate defining a substrate plane. A liquid precursor (64) including a thinning agent that reduces the surface tension in said liquid precursor solution to a value ranging from 10 to 40 dynes per centimeter is misted by ultrasonic or venturi apparatus, to produce a colloidal mist. The mist is generated, allowed to settle in a buffer chamber, filtered through a system up to 0.01 micron, and flowed into the deposition chamber between the substrate and barrier plate to deposit a liquid layer on the substrate. The liquid is dried to form a thin film of solid material on the substrate, which is then incorporated into an electrical component of an integrated circuit.

A laminate, comprising a substrate and at least two controlled droplet-formed layers further comprising an array of discrete placed material volumes having a thickness extent, each material volume having a selected magnitude and a selected position relative to adjacent material volumes, said array being formed by deposition of droplets of selected volume at selected locations with respect to one another.

A control system (100) for a process using supercritical fluid (104) includes a reactor vessel (120) including an agitator (130) for mixing a batch of materials therein, a source of supercritical fluid (102) supplied to the reactor vessel (120), device for introducing into the reactor vessel (120) batch material that is mixed in the presence of the supercritical fluid (104) based on a selectable reaction process (110), process monitoring device (152) for producing signals representative of the reaction in the reaction vessel (120); and control device (156) for controlling the reaction in the reaction vessel (120) based on the signals and the selected reaction process.
Abstract:
A liquid precursor containing a metal is applied to a substrate, RTP baked, and annealed to form a layered superlattice material. Special polyoxyalkylated precursor solutions are designed to optimize polarizability of the corresponding metal oxide materials by adding dopants including stoichiometric excess amounts of bismuth and tantalum. The RTP baking process is especially beneficial in optimizing the polarizability of the resultant metal oxide.
Abstract:
The present invention relates to coating and printing methods for the deposition of aqueous compositions. The composition may be adapted to any method without the need to change its chemical content. Viscosity is determined and adjusted by raising and lowering the temperature. High gloss value, increased film integrity and enhanced mar resistance result.
