Nano technologies are widely recognized as enabling enhanced and new functionality in a wide range of applications and products. Many different ways have been developed to create and apply these nanomaterials. One method for making dry nanocoatings is vapor deposition. There exists a need for a portable machine that can apply nanocoatings to a wide of range of surfaces in a wide range of locations. The present invention comprises such a portable machine that can apply nanocoatings to a wide of range of surfaces in a wide range of locations.

The present disclosure is directed to an apparatus and method of sintering inorganic powder coatings on substrates, and includes a flame and an electric plasma. The method is capable of being used in an open atmospheric environment. The substrate is electrically conductive and is used as one electrode while the flame is used as the other electrode that is moved over the areas of the powder coating to be sintered. An electrical current is used to cause a plasma produced through the flame, resulting in a combined energy and temperature profile sufficient for inorganic powder-powder and powder-substrate bonding. This method is referred to as flame-assisted flash sintering' (FAFS).

Tunable radio frequency (RF) devices, such as phase shifters and filters, are formed by depositing thin film layers on a substrate and patterning the thin film layers by various lithography techniques. A thin film metal layer is patterned to form a plurality of capacitors and inductors, leaving at least two grounding regions that lie closely adjacent the capacitors and inductors. As patterned portions of the grounding regions are electrically isolated from each other. Performance of the devices are improved by electrically bridging the differential potential grounding regions.

The process of the present invention significantly increases the durability of superhydrophobic surfaces, while retaining similar optical properties to those of the original surface. The process uses velocity and heat to take freshly formed nano- and ultrafine particles and can partially embed and chemically bond them to the substrate, creating a strongly bonded nano-to-submicron textured surface. This nanotextured surface can then be modified to have desirable surface properties; for example, it can be hydrophobic, oliophobic, or hydrophilic. The high points of the coating made with this process protect the remainder of the surface from abrasion, thus greatly increasing product life in many uses. In preferred embodiments, the process is used to coat transportation vehicle windshields.

The invention is a tunable RF MEMS switch developed with a BST dielectric at the contact interface. BST has a very high dielectric constant (&#x3e;300) making it very appealing for RF MEMS capacitive switches. The tunable dielectric constant of BST provides a possibility of making linearly tunable MEMS capacitive switches. The capacitive tunable RF MEMS switch with a BST dielectric is disclosed showing its characterization and properties up to 40 GHz.

Nanoparticulates of oxygen transfer materials that are oxides of rare earth metals, combinations of rare earth metals, and combinations of transition metals and rare earth metals are used as catalysts in a variety of processes. Unexpectedly large thermal efficiencies are achieved relative to micron sized particulates. Processes that use these catalysts are exemplified in a multistage reactor. The exemplified reactor cracks C6 to C20 hydrocarbons, desulfurizes the hydrocarbon stream and reforms the hydrocarbons in the stream to produce hydrogen. In a first reactor stage the steam and hydrocarbon are passed through particulate mixed rare earth metal oxide to crack larger hydrocarbon molecules. In a second stage, the steam and hydrocarbon are passed through particulate material that desulfurizes the hydrocarbon. In a third stage, the hydrocarbon and steam are passed through a heated, mixed transition metal/rare earth metal oxide to reform the lower hydrocarbons and thereby produce hydrogen. Stages can be alone or combined. Parallel reactors can provide continuous reactant flow. Each of the processes can be carried out individually.

Nanoparticulate-catalyzed oxygen transfer processes

Flame produced vapors for combustion chemical vapor deposition are redirected from the direction of the flame by differential atmospheric pressure, such as positive pressure provided by a blower or negative pressure provided by a vacuum. This allows, for example, lower surface temperatures of substrates being coated with flame-produced vapors and coating of interior surfaces.

Electronic and optical (or photonic) devices with variable or switchable properties and methods used to form these devices, are disclosed. More specifically, the present invention involves forming layers of conductive material and dielectric material or materials with varying conductivity and indexes of refraction to form various electronic and optical devices. One such layer of adjustable material is formed by depositing epitaxial or reduced grain boundary barium strontium titanate on the C-plane of sapphire.

Electronic and optical devices and methods of forming these devices

A coherent material is formed on a substrate () by providing a precursor suspension () in which particulates are suspended in a carrier fluid, and directing the precursor suspension () at the substrate () from a first source (). Generally contemporaneously with application of the deposited precursor suspension () to the surface, hot gases, e.g. hot gases produced by a flame (), are directed at the substrate () from a remote second source () to fuse the particulates into the coherent material.

Capacitors) having a fluid dielectric material that is transported or undergoes a phase change are disclosed. The dielectric medium change results in a change in the total dielectric constant of the material between the electrodes (), thus changing the capacitance of the capacitors. Transporting or phase changing the dielectric fluids into and out of a the electric field of the capacitor, changes the effective dielectric constant and the capacitance of the capacitor.

Tunable capacitors using fluid dielectrics

To form an ionomer-based catalytic layer on a porous substrate, a heat source () is used to dry an ionomer-containing spray () so that it does not substantially liquid flow on the substrate (). The ionomer spray () may contain a catalyst. A spray () of mixed material for forming the catalytic layer is entrained by a gas stream and is heated and directed to a substrate surface (). For hydrogen/oxygen fuel cells, catalytic material is incorporated into the proton-conducting membrane () to convert diffusing oxygen and hydrogen to water to reduce potential loss at the electrodes and maintain hydration of the proton-conducting membrane ().

Fuel cell membranes and catalytic layers

Tubular needles have a reduced inner diameter tip portion that increases back pressure behind the tip portion. This constricted tip portion promotes improved atomization, particularly when the liquid passes through the needle at near-supercritical conditions. A preferred method for constricting the inner diameter of a needle tip is to dip the dip of the needle in an electroless plating solution, such as an electroless nickel solution.

Transporting or phase changing the dielectric fluids into and out of a the electric field of the capacitor, changes the effective dielectric constant and the capacitance of the capacitor.
