  • Patent number: 11180854
    Abstract: The invention provides a thin film deposition system and a method, and relates to the field of thin film deposition. The deposition method comprises the following steps: 1) heating metal substrate; carrying out deposition. The method is characterized in the step 1) that a current is conducted into the metal substrate at one end of the growth zone by one electrode, and out of the metal substrate at the other end of the growth zone by the other electrode, so that the metal substrate is heated by the heat emitting of the resistant of the metal substrate itself. According to the method, the quality of the prepared thin film is improved, while the preparation cost of the thin film is reduced. In addition, the consistent double-sided thin films can be easily prepared on two surfaces of the metal substrate by employing the system and method.

  • Patent number: 11158502
    Abstract: Methods of forming porous nano-scale or micro-scale structured materials and structured materials formed thereby. Such methods entail providing a donor material and reacting the donor material to form a compound that deposits on a surface of a substrate to produce nano-scale or micro-scale geometric features of the structured material. In particular embodiments, the donor material is in a solution and the reacting step is performed by contacting the surface of the substrate with the solution and directing heat through the solution onto the surface to locally heat a portion of the solution in contact therewith.

  • Patent number: 11140954
    Abstract: A method to permanently mark an item of plated jewelry involves creating a laminate of two metals, and upper layer typically formed of a more precious metal such as gold, platinum and palladium that do not readily oxidize laminated onto the surface of a less precious metal, such as silver, which is oxidized to create a dark color (e.g. black). A laser is used to create characters and/or designs in the upper layer by vaporizing portions to effectively remove those portions. This exposes the upper surface of the less precious metal that does become oxidized. An oxidizer, such as liquid sulfur, is used to blacken the silver, typically a dark gray. This allows an easy and inexpensive method of archiving information on jewelry bearing or supporting a gem that describes the supported gem rendering the gem more valuable collectible and traceable.

  • Patent number: 11111593
    Abstract: A process for the large scale manufacturing of vertically standing hybrid nanometer-scale structures of different geometries, including fractal architecture made of flexible materials, on a flexible substrate including textiles is disclosed. The nanometer-scale structures increase the surface area of the substrate. The nanometer-scale structures may be coated with materials that are sensitive to various physical parameters or chemicals such as but not limited to temperature, humidity, pressure, atmospheric pressure, electromagnetic signals originating from biological or non-biological sources, volatile gases, and pH. The increased surface area achieved through the disclosed process is intended to improve the sensitivity of the sensors formed by coating of the nanometer-scale structure and substrate with a material which can be used to sense physical parameters and chemicals as listed previously.

  • Patent number: 11072860
    Abstract: Methods and apparatus for use of a fill on demand ampoule are disclosed. The fill on demand ampoule may refill an ampoule with precursor concurrent with the performance of other deposition processes. The fill on demand may keep the level of precursor within the ampoule at a relatively constant level. The level may be calculated to result in an optimum head volume. The fill on demand may also keep the precursor at a temperature near that of an optimum precursor temperature. The fill on demand may occur during parts of the deposition process where the agitation of the precursor due to the filling of the ampoule with the precursor minimally effects the substrate deposition. Substrate throughput may be increased through the use of fill on demand.
