  • Patent number: 10916407
    Abstract: Embodiments of the present disclosure generally relate to methods for conditioning an interior wall surface of a remote plasma generator. In one embodiment, a method for processing a substrate is provided. The method includes exposing an interior wall surface of a remote plasma source to a conditioning gas that is in excited state to passivate the interior wall surface of the remote plasma source, wherein the remote plasma source is coupled through a conduit to a processing chamber in which a substrate is disposed, and the conditioning gas comprises an oxygen-containing gas, a nitrogen-containing gas, or a combination thereof. The method has been observed to be able to improve dissociation/recombination rate and plasma coupling efficiency in the processing chamber, and therefore provides repeatable and stable plasma source performance from wafer to wafer.

The invention addresses the problem of corrosion or interference of metal components in the flow path for LC analyses in which the sample interacts with metal ions or surfaces. The invention also alleviates the difficulties in coating very long metal tubes and very small metal channels with an inert, continuous coating that adheres well to metal surfaces. The metal flow path is rendered inert by the coating, and thus compatible with bioanalytical separations, for example, by using a vapor phase deposition process to coat the inner surfaces with a coating that continuously covers all metal surfaces in the flow path.

    Abstract: An isothermal, low pressure-based process of depositing material within a substrate has been developed and results in creating an extremely narrow reaction zone within which a more uniform and efficient deposition will occur. Sets of isothermal plasma operating conditions have been found that create a narrow deposition zone, assuring that the deposited material is clear glass rather than soot particles. The chemical delivery system, in one arrangement, utilizes rods of solid phase source material (which may otherwise be difficult to obtain in gaseous form). The operating conditions are selected such that the hot plasma does not transfer a substantial amount of heat to the substrate tube, where the presence of such heat has been found to result in vaporizing the reactant material (creating soot) and developing hot spots.

The coating film (4) may be formed only within a portion of the graphite crucible in which SiC formation can occur easily, not over the entirety of the surface of the graphite crucible. For example, it is possible to deposit the film only on the entire inner surface of the crucible. It is also possible to deposit the film only on a curved portion (sharply curved portion) of the inner surface, or only on a curved portion and a straight trunk portion.

  • Patent number: 8574671
    Abstract: A method for adjusting the coolant consumption within actively cooled components is produced. The components include an interior with at least one duct with different regions which have different cross sections of flow. A greater increase in the wall thickness is produced in the region having the smaller cross section of flow by a first diffusion process and a lesser increase in the wall thickness is produced in the region having the larger cross section of flow by a second diffusion process which is different from the first. By using different diffusion coatings in a component, it is possible to adjust the flow of coolant through a component in a controlled way.

  • Publication number: 20130273248
    Abstract: Methods and devices for the production of glass fiber preforms are disclosed. The methods and devices are based on a modified chemical vapour deposition process wherein the reacting gases are reacted in a hot zone within a substrate tube. Glass layers are deposited by a first heating instrument moving with respect to the substrate tube. The reaction gases are subjected to a temperature treatment before entering the hot zone of the main burner to encourage an evenly distributed chemical reaction, deposition and doping concentration over the length of the substrate tube. This is based on the position of the substrate tube with respect to the heating instrument and the resulting different heating of the reaction gases.

  • Publication number: 20130247818
    Abstract: A silica crucible and a fabricating method thereof are provided. The silica crucible includes a vitreous silica body having an inner surface and an outer surface, the inner surface of the vitreous silica body defining a cavity adapted for containing a molten material or a powder material; and a first coating layer formed on the inner surface of the vitreous silica body. The first coating layer is formed by pyrolysing a composite of aluminum, magnesium, calcium, titanium, zirconium, radium, chromium, selenium, barium, yttrium, cerium, hafnium, tantalum, tin or silicon under a predetermined temperature. The first coating layer substantially includes of a nonhomogeneous material, and an interface is defined by the homogeneous material and the nonhomogeneous material between the vitreous silica body and the coating layer. The first coating layer has strong adhesion capability and guarantees the coating layer will not be easily peeled off or removed.

    Abstract: A crucible for forming a boule in a portion of an interior volume of the crucible. The crucible has a crucible base material forming the interior volume. The crucible base material is separated from the boule by a barrier coat disposed between the boule and the crucible base material. The barrier coat has a pin free conformal thickness conforming to a surface of the crucible base material regardless of a shape of a surface feature on the surface, the barrier coat having a melting point higher than that of the boule.

  • Patent number: 8529992
    Abstract: The present disclosure includes a method of applying a coating material to an air duct including inserting a first end of a supply line including a spray head and a camera through a first opening in the air duct; initiating flow of coating material to the spray head through the supply line; pulling the supply line and the attached spray head and camera so that the spray head deposits coating material onto the interior surfaces of the duct while capturing the deposition of coating material using the camera. Using the process and apparatus of the present disclosure provides for the coating of the inside of a air duct while being able to observe and monitor the deposition of coating material in order to ensure that the coating material is applied consistently and evenly along the length of the air duct.

    Abstract: In an embodiment, a method for manufacturing a chromatography apparatus such as a thin layer chromatography (“TLC”) plate is disclosed. The method includes forming a layer of elongated nanostructures (e.g., carbon nanotubes), oxidizing the elongated nanostructures to form a surface enriched in oxygen moieties, and at least partially coating the oxidized elongated nanostructures with a coating. The coating includes a stationary phase and/or precursor of a stationary phase for use in chromatography. The stationary phase may be functionalized with hydroxyl groups by exposure to a base or acid. The stationary phase may further be treated with a silane (e.g., an amino silane) to improve the performance of the chromatography apparatus. Embodiments for TLC plates and related methods are also disclosed.

    Abstract: Processes and methods are provided for applying corrosion inhibitor within a foam matrix to the top of the line of wet gas pipelines. The environment within a hydrocarbon containing pipeline may include fluids that form strong acids in the gas space at the upper portion of the pipeline and can rapidly corrode a carbon steel pipeline. The solution provides a foam matrix created by a combination of foaming agent, foaming gas and corrosion inhibitor that are each selected to be compatible with each other and with the hydrocarbon mixture to form a stable foam matrix that treats the top of the line position for the length of the pipeline. A foam breaking agent at the end of the pipeline can be injected, if needed.
