  • Patent number: 9017777
    Abstract: A method for manufacturing thin films for a battery device. The method includes vaporizing a precursor material from a liquid source to form droplets ranging from, for example, about 10 microns to about 20 microns. Thereafter, the method includes subjecting the droplets from about 10 to about 20 microns to a megasonic energy source to cause formation of a plurality of smaller droplets ranging from, for example, about 0.25 micron to about 5 microns which are then directed to a heated substrate, where through a heterogeneous reaction a film of material overlying the surface region is formed. The method includes irradiating (e.g., ultra-violet, infra-red, or plasma) the film of material using electromagnetic radiation to process the film to cause a recrystallization of the film to form larger sized crystalline materials. Optionally, the method includes sequentially performing the vaporizing, reacting/releasing, and irradiating to build up a thickness of the film of material.

  • Patent number: 9017773
    Abstract: A method is described for depositing nanostructures, such as nanostructures of conducting polymers, carbon nanostructures, or combinations thereof. The process comprises placing the nanostructures in a liquid composition comprising an immiscible combination of aqueous phase and an organic phase. The mixture is mixed for a period of time sufficient to form an emulsion and then allowed to stand undisturbed so that the phases are allowed to separate. As a result the nanostructure materials locate at the interface of the forming phases and are uniformly dispersed along that interface. A film of the nanostructure materials will then form on a substrate intersecting the interface, said substrate having been placed in the mixture before the phases are allowed to settle and separate.

    Abstract: A single or multi-component polymer coating is applied to components used in fabrication of electrochemical cells to protect the cells from damages that can result in cell imbalance or cell performance reduction. The polymer coating is electrically conductive under normal operating conditions but, when operated at low voltages, functions as an insulative material that increases the electrical resistance of the cell components. This increased electrical resistance improves cell safety by minimizing short-circuit current flow and reducing heating rate in the cell components.

  • Publication number: 20140083752
    Abstract: A degradable polymeric nanotube (NT) dispersant comprises a multiplicity of NT associative groups that are connected to a polymer backbone by a linking group where there are cleavable groups within the polymer backbone and/or the linking groups such that on a directed change of conditions, bond breaking of the cleavable groups results in residues from the degradable polymeric NT dispersant in a manner where the associative groups are uncoupled from other associative groups, rendering the associative groups monomelic in nature. The degradable polymeric nanotube (NT) dispersant can be combined with carbon NTs to form a NT dispersion that can be deposited to form a NT film, or other structure, by air brushing, electrostatic spraying, ultrasonic spraying, ink-jet printing, roll-to-roll coating, or dip coating. The deposition can render a NT film that is of a uniform thickness or is patterned with various thicknesses.

  • Patent number: 8658248
    Abstract: A method for atomizing a liquid including providing an atomizer having a liquid supply conduit having an outlet at one end, a gas supply conduit opening into a port in the liquid supply conduit upstream of the outlet, and a means for imparting vibrational energy to the atomizer. In an embodiment, the liquid supply conduit and gas supply conduit are coaxially displaced relative to one another. The method further includes flowing liquid through the liquid supply conduit to the outlet while simultaneously flowing gas through the gas supply conduit, and imparting vibrational energy to the atomizer to atomize the liquid exiting from the outlet. The introduction of gas at the port results in a spray of droplets with improved dimensional properties.

  • Patent number: 8623662
    Abstract: Methods, processes and compositions are provided for a visual or chemochromic hydrogen-detector with variable or tunable reversible color change. The working temperature range for the hydrogen detector is from minus 100° C. to plus 500° C. A hydrogen-sensitive pigment, including, but not limited to, oxides, hydroxides and polyoxo-compounds of tungsten, molybdenum, vanadium, chromium and combinations thereof, is combined with nano-sized metal activator particles and preferably, coated on a porous or woven substrate. In the presence of hydrogen, the composition rapidly changes its color from white or light-gray or light-tan to dark gray, navy-blue or black depending on the exposure time and hydrogen concentration in the medium. After hydrogen exposure ceases, the original color of the hydrogen-sensitive pigment is restored, and the visual hydrogen detector can be used repeatedly.

  • Patent number: 8595929
    Abstract: A composition and method for cleaning turbine engine components (10) during servicing. An embodiment of the invention includes a colloidal mixture or slurry (22) of nanoparticles. The slurry may be nontoxic and provide optimal cleaning of tiny surface-exposed crevices (18) of braze joints and components. When a colloidal mixture is in a polar solvent, the pH of the slurry is maintained at about 5 to 9 and at the isoelectric point of the nanoparticles to minimize or prevent agglomeration. When a colloidal mixture is in a nonpolar solvent, the pH of the slurry is maintained at about 5 to 9 and at the isoelectric point of the nanoparticles to minimize or prevent agglomeration by use of surfactant additives.
