| 20080298997 | Platinum Alloy and Method of Production Thereof - The disclosure relates to a platinum alloy comprising (a) 55 to 63 wt. % of platinum, (b) 2 to 10 wt. % of cobalt, and (c) 27 to 43 wt. % of copper. The disclosure further relates to a platinum alloy comprising (a) 70 to 79.5 wt. % of platinum, 2 to 10 wt. % of cobalt, and (c) 10.5 to 28 wt. % of copper. The platinum alloys have excellent mechanical and optical properties for use in the production of ornamental articles such as rings, necklaces, earrings, watch bands, watch bodies and other jewelry. The disclosure further relates to a method of preparing the platinum alloys and their use in the production of ornamental articles. Still further the disclosure relates to ornamental articles comprising the platinum alloy and a method of production thereof. | 12-04-2008 |
| 20090047170 | Oxide-Dispersion Strengthened Platinum Material - The present invention provides an oxide-dispersion-strengthened platinum material in which dispersed particles made from a metallic oxide of an additive metal are dispersed in a matrix made from platinum or a platinum alloy, characterized in that the concentration of oxygen in the material except oxygen bound to the additive metal is 100 ppm or lower. The platinum material according to the present invention has preferably an average diameter of the dispersed particles of 0.2 μm or smaller, and an average interparticle distance of 0.01 to 2.7 μm. The platinum material also preferably has the concentration of the dispersed particles in an amount of 0.01 to 0.5 wt %, and an oxidation rate of the additive metal of 50 to 100%. | 02-19-2009 |
| 20090297389 | CONDUCTIVE MATERIAL - Provided is a conductive material to be used for a resistor and a sensor, which is enhanced its mechanical strength while maintaining a stable resistance ratio. In the conductive material used for the resistor and the sensor, 400 to 10,000 ppm of Sr is contained in Pt, and the balance is an inevitable impurity. An intermetallic compound phase formed of Pt and Sr is precipitated and dispersed in Pt. | 12-03-2009 |
| 20100296963 | CRYSTAL STRUCTURE OF A PLASMA MEMBRANE PROTON PUMP - The present invention relates to a crystal structure of a plasma membrane proton pump type ATPase. The invention further describes method for identification of modulators of ATPases as well as uses of such modulators. Based on the provided three dimensional structure of the ATPase, various method, such as computer implemented methods may be used for identification of modulators, such putative modulators may be further analysed using in vitro and in vivo experiments to confirm there functionality. Several modulator interaction regions are described as target of regulation by ATPase modulators. | 11-25-2010 |
| 20120156088 | PREPARATION OF FePt AND CoPt NANOPARTICLES - The invention provides a method for the preparation of FePt or CoPt nanoparticles in ionic liquids, which in certain embodiments constitutes a direct method for the preparation of such nanoparticles having the face-centred tetragonal (fct) crystalline form. The invention also provides FePt or CoPt nanoparticles obtainable by a method of the invention. | 06-21-2012 |
| 20120237392 | MAGNETIC MATERIAL - A magnetic material includes a main alloy having a rhombohedral crystal structure and a composition represented by Co | 09-20-2012 |
| 20120269675 | MATERIAL FOR SPARK PLUG ELECTRODE HAVING EXCELLENT SPARK WEAR RESISTANCE AND DISCHARGE PROPERTIES - A material for a plug electrode having not only excellent oxidation wear resistance but also excellent spark wear, and also having adequately-considered discharge properties in use is provided. The present invention relates to a material for a plug electrode, comprising 5% by mass or more and 30% by mass or less of Cu, 0.1% by mass or more and 15% by mass or less of Ir, with the balance being Pt. Alloying by combining two metals of Cu and Ir can reduce discharge voltages and improve durability against spark wear. With addition of only one of them, the effect of improving spark wear properties is poor and the effect of reducing discharge voltages cannot be expected. | 10-25-2012 |
| 20140255247 | METHOD FOR PRODUCING HIGHLY PURE PLATINUM POWDER, AS WELL AS PLATINUM POWDER THAT CAN BE OBTAINED ACCORDING TO SAID METHOD, AND USE THEREOF - A method for producing highly pure platinum on an industrial scale, as well as the use of said highly pure platinum. According to the method, a hexahalogenoplatinate is reduced to platinum in acidic conditions. | 09-11-2014 |
