Abstract:

Nanometer to micrometer sized particles containing platinum and having selected morphologies are prepared by a sonochemical process. A compound of platinum is dissolved, suspended, or diluted in a suitable liquid medium at a predetermined concentration and the liquid is maintained at a predetermined temperature from sub-ambient temperatures to above ambient temperatures. A reducing gas is bubbled through the liquid as it is subjected to cavitation at a controlled power to affect the reductive decomposition of the platinum compound. The morphology of the precipitated platinum particles can be varied widely by varying the described concentration, temperature and power parameters.

Abstract:

Nanometer sized particles containing titanium and platinum are prepared by a sonochemical process. Compounds of the metals are dissolved, suspended, or diluted in a low vapor pressure liquid medium, preferably at a sub-ambient temperature. A reducing gas is bubbled through the liquid as it is subjected to cavitation to affect the reductive decomposition of the metal compounds. Titanium and platinum are co-precipitated in very small particles.

Abstract:

A precursor halide compound is reduced to a predetermined product at substantially ambient conditions. The halide is added to an anhydrous liquid reaction medium containing one or more alkali metals or alkaline earth metals as reductants. The metal reductants are dispersed as very small globules in the liquid by cavitation of the liquid, such as by application of high intensity ultrasonic vibrations or high-shear mixing to the reaction vessel. Continued cavitation of the liquid medium affects low temperature reduction of the precursor halide(s) to produce a metal, metal alloy, metal compound, ceramic material, metal matrix-ceramic composite material, or the like. The practice may be applied, for example, to titanium tetrachloride, alone or with other chlorides, to produce titanium metal, titanium alloys (for example Ti-6Al-4V), and titanium compounds (TiSi).

Abstract:

A headrest assembly for a seat includes a body portion having at least one padded surface positioned in substantial alignment with a seated occupant's head; and an active material in operative communication with the at least one padded surface of the body portion, the active material being operative to change at least one attribute in response to an activation signal, wherein a space between the occupant's head and the at least one padded surface decreases with the change in the at least one attribute of the active material.

International Classification:

US Classification:

429 42, 429 44, 502177

Abstract:

The durability of a fuel cell having a polymer electrolyte membrane with an anode on one surface and an oxygen-reducing cathode on the other surface is improved by substituting electrically conductive titanium carbide or titanium nitride particles for carbon particles as oxygen-reducing and hydrogen-oxidizing catalyst supports. For example nanosize platinum particles deposited on nanosize titanium carbide or titanium nitride support particles provide good oxygen reduction capability and are corrosion resistant in an acid environment. It is preferred that the catalyst-on-titanium carbide (nitride) particles be mixed with non-catalyst-bearing carbon in the electrode material for improved electrode performance.

US Classification:

429 44, 429 40

Abstract:

The durability of a fuel cell having a polymer electrolyte membrane with an anode on one surface and an oxygen-reducing cathode on the other surface is improved by replacing conductive carbon matrix materials in an electrode with a matrix of electrically conductive metal compound particles. The electrode includes a catalyst supported on a nanosize metal oxides and electrically conductive nanosize matrix particles of a metal compound. One or more metal compounds such as a boride, carbide, nitride, silicide, carbonitride, oxyboride, oxycarbide, or oxynitride of a metal such as cobalt, chromium, nickel, molybdenum, neodymium niobium, tantalum, titanium, tungsten, vanadium, and zirconium is suitable. For example, the combination of platinum particles deposited on titanium dioxide support particles mixed in a conductive matrix of titanium carbide particles provides an electrode with good oxygen reduction capability and corrosion resistance in an acid environment.
