V.sub.2O.sub.5 electrodes with high power and energy densities

Patent Cao, Guozhong; Liu, Yanyi

Methods are provided for forming films of orthorhombic V.sub.2O.sub.5. Additionally provided are the orthorhombic V.sub.2O.sub.5 films themselves, as well as batteries incorporating the films as cathode materials. The methods use electrodeposition from a precursor solution to form a V.sub.2O.sub.5 sol gel on a substrate. The V.sub.2O.sub.5 gel can be annealed to provide an orthorhombic V.sub.2O.sub.5 film on the substrate. The V.sub.2O.sub.5 film can be freestanding such that it can be removed from the substrate and integrated without binders or conductive filler into a battery as a cathode element. Due to the improved intercalation properties of the orthorhombic V.sub.2O.sub.5 films, batteriesmore » « less

Pd menbrane having improved H.sub.2-permeance, and method of making

Patent Vanderspurt, Thomas Henry [Glastonbury, CT]; She, Ying [Worcester, MA]; Dardas, Zissis [Worcester, MA]; ...

An H.sub.2-permeable membrane system (117) comprises an electroless-deposited plating (115) of Pd or Pd alloy on a porous support (110, 110'). The Pd plating comprises face-centered cubic crystals cumulatively having a morphology of hexagonal platelets. The permeability to H.sub.2 of the membrane plating (115) on the porous support is significantly enhanced, being at least greater than about 1.3.times.10.sup.-8 molm.sup.-1s.sup.-Pa.sup.-0.5 at 350.degree. C., and even greater than about 3.4.times.10.sup.-8 molm.sup.-1s.sup.-1Pa.sup.-0.5. The porous support (110, 110') may be stainless steel (1100 and include a thin ceramic interlayer (110') on which the Pd is plated. The method of providing the electroless-deposited plating includesmore » « less

Simple, field portable colorimetric detection device for organic peroxides and hydrogen peroxide

Patent Pagoria, Philip F [Livermore, CA]; Mitchell, Alexander R [Livermore, CA]; Whipple, Richard E [Livermore, CA]; ...

A simple and effective system for the colorimetric determination of organic peroxides and hydrogen peroxide. A peroxide pen utilizing a swipe material attached to a polyethylene tube contains two crushable vials. The two crushable vials contain a colorimetric reagent separated into dry ingredients and liquid ingredients. After swiping a suspected substance or surface the vials are broken, the reagent is mixed thoroughly and the reagent is allowed to wick into the swipe material. The presence of organic peroxides or hydrogen peroxide is confirmed by a deep blue color.

X-ray-induced dissociation of H.sub.2O and formation of an O.sub.2-H.sub.2 alloy at high pressure

Patent Mao, Ho-kwang [Washington, DC]; Mao, Wendy L [Washington, DC]

A novel molecular alloy of O.sub.2 and H.sub.2 and a method of producing such a molecular alloy are provided. When subjected to high pressure and extensive x-radiation, H.sub.2O molecules cleaved, forming O--O and H--H bonds. In the method of the present invention, the O and H framework in ice VII was converted into a molecular alloy of O.sub.2 and H.sub.2. X-ray diffraction, x-ray Raman scattering, and optical Raman spectroscopy demonstrate that this crystalline solid differs from previously known phases.

Method and Pd/V2 O5 device for H2 detection

Patent Liu, Ping [San Diego, CA]; Tracy, C Edwin [Golden, CO]; Pitts, J Roland [Lakewood, CO]; ...

Methods and Pd/V.sub.2O.sub.5 devices for hydrogen detection are disclosed. An exemplary method of preparing an improved sensor for chemochromic detection of hydrogen gas over a wide response range exhibits stability during repeated coloring/bleaching cycles upon exposure and removal of hydrogen gas. The method may include providing a substrate. The method may also include depositing a V.sub.20.sub.5 layer that functions as a H.sub.2 insertion host in a Pd/V.sub.20.sub.5 hydrogen sensor to be formed on said substrate. The method may also include depositing a Pd layer onto said V.sub.20.sub.5 layer; said Pd layer functioning as an optical modulator.
