20080271569 | CAVITATION PROCESS FOR TITANIUM PRODUCTS FROM PRECURSOR HALIDES - A titanium halide and, optionally, other precursor halides compound are reduced to a predetermined titanium product, suitably at or near ambient conditions. Titanium tetrachloride, for example, 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 reaction medium, such as by application of high intensity ultrasonic vibrations or high-shear mixing to the reaction vessel. Continued cavitation of the liquid medium affects relatively low temperature reduction of the precursor halide(s) to produce a titanium-containing product such as titanium metal, a titanium alloy or compound, or a titanium matrix-ceramic composite material, or the like. | 11-06-2008 |

20080295645 | CAVITATION PROCESS FOR PRODUCTS FROM PRECURSOR HALIDES - 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 | 12-04-2008 |
20090068357 | MAGNESIUM-TITANIUM SOLID SOLUTION ALLOYS - Films of magnesium mixed with titanium are produced by non-equilibrium alloying processes such as electron beam evaporation of magnesium and titanium ingots in a very low pressure chamber. Such magnesium-titanium films form as single phase solid solutions. Titanium is inherently resistant to corrosion and its admixture with magnesium in solid solution provides a new composition that is less subject to intra-film galvanic corrosion. The magnesium-titanium films also provide relatively hard and strong coatings. | 03-12-2009 |

20100151295 | ANODE MATERIALS FOR PEM FUEL CELLS - The incorporation of tungsten-containing hydrogen spillover materials into a composite fuel cell anode can be helpful in preserving the carbon catalyst support materials in the fuel cell cathode during periods of hydrogen starvation. Preferred examples of such tungsten-containing hydrogen spillover materials are tungsten oxides and tungsten silicides. These materials, when physically mixed with catalyst-loaded carbon support particles in a composite anode, have shown the ability to promote hydrogen storage in amounts that, during a disruption of hydrogen gas flow, can postpone an anodic potential excursion into the oxygen evolution region for a period of at least several seconds. | 06-17-2010 |

20130299688 | TECHNIQUES FOR ANALYZING MASS SPECTRA FROM THERMAL DESORPTION RESPONSE - Techniques are described for sample analysis. Thermal desorption of components of the sample occurs at atmospheric pressure at a plurality of times by applying one of a plurality of temperatures included in a temperature gradient at each of the times to a surface of the sample. Desorption of each component occurs at a different temperature thereby allowing differentiation of the components based on one of the times corresponding to the temperature at which desorption occurs for the component. Ions are generated from the thermally desorbed components. Mass spectra generated from the ions are analyzed to determine mass spectral features about the components. Analyzing includes associating one of the ions with a component if the one ion has an ion intensity apex or peak that is detected in the mass spectra and occurs at a time corresponding to a one of the temperatures at which thermal desorption occurs for the component. | 11-14-2013 |
