    Abstract: A process for forming a coating on a conductive substrate, including the steps of: establishing a fluidised-bed of a powder coating composition, thereby effecting tribostatic charging of the powder coating composition, the fluidised-bed including a fluidising chamber at least a part of which is conductive, applying a voltage to the conductive part of the fluidising chamber, immersing the substrate wholly or partly in the fluidised bed, whereby charged particles of the powder coating composition adhere to the substrate, the substrate being either electrically isolated or earthed, withdrawing the substrate from the fluidised-bed and forming the adherent particles into a continuous coating over at least part of the substrate. The process offers advantages in terms of coating substrate areas which, because of the Faraday cage effect, are inaccessible in conventional electrostatic powder coating processes, and also enables the formation of thinner coatings than are obtainable by conventional fluidised-bed processes.

    Abstract translation: 一种在导电基材上形成涂层的方法，包括以下步骤：建立粉末涂料组合物的流化床，从而对粉末涂料组合物进行摩擦阻尼加载，流化床包括流化室至少部分 其导电，向流化室的导电部分施加电压，将基底完全或部分地浸入流化床中，由此粉末涂料组合物的带电粒子粘附到基底上，该基底被电隔离或接地，取出 来自流化床的基底并且在至少部分基底上形成粘附颗粒成连续的涂层。 该方法在涂布基材面积方面具有优势，由于法拉第笼式效应，在常规静电粉末涂覆方法中不可接触，并且还能够形成比通过常规流化床方法可获得的更薄的涂层。

    Abstract: A method of operation of a plasma torch and the plasma apparatus to produce a hot gas jet stream directed towards a workpiece to be coated by first injecting a cold high pressure carrier gas containing a powder material into a cold main high pressure gas flow and then directing this combined high pressure gas flow coaxially around a plasma exiting from an operating plasma generator and converging directly into the hot plasma effluent, thereby mixing with the hot plasma effluent to form a gas stream with a net temperature based on the enthalpy of the plasma stream and the temperature and volume of the cold high pressure converging gas, establishing a net temperature of the gas stream at a temperature such that the powdered material will not melt or soften, and projecting the powder particles at high velocity onto a workpiece surface. The improvement resides in mixing a cold high pressure carrier gas with powder material entrained in it, with a cold high pressure gas flow of gas prior to mixing this combined gas flow with the plasma effluent which is utilized to heat the combined gas flow to an elevated temperature limited to not exceeding the softening point or melting point of the powder material. The resulting hot high pressure gas flow is directed through a supersonic nozzle to accelerate this heated gas flow to supersonic velocities, thereby providing sufficient velocity to the particles striking the workpiece to achieve a kinetic energy transformation into elastic deformation of the particles as they impact the onto the workpiece surface and forming a dense, tightly adhering cohesive coating. Preferably the powder material is of metals, alloys, polymers and mixtures thereof or with semiconductors or ceramics and the powder material is preferably of a particle size range exceeding 50 microns. The system also includes a rotating member for coating concave surfaces and internal bores or other such devices which can be better coated using rotation.

    Abstract: The invention provides a lithographic method referred to as “dip pen” nanolithography (DPN). DPN utilizes a scanning probe microscope (SPM) tip (e.g., an atomic force microscope (AFM) tip) as a “pen,” a solid-state substrate (e.g., gold) as “paper,” and molecules with a chemical affinity for the solid-state substratte as “ink.” Capillary transport of molecules from the SPM tip to thee solid substrate is used in DPN to directly write patterns consisting of a relatively small collection of molecules in submicrometer dimensions, making DPN useful in the facrication of a variety of microscale and nanoscale devices. The invention also provices substrates patterened by DPN, including submirocmeter combinatorial arrays, and kits, devices and software for performing DPN. The invention further provides a method of performing AFM imaging in air. The method comprises coating an AFM tip with a hydrophobic compound, the hydrophobic compoind being selected so that AFM imaging perfromed using the coated AFM tipn is improved compared to AFM imaging preformed using an uncoated AFM tip. Finally, the invention provides AFM tips coated with the hydrophobic compounds.
