By controlling various laser parameters, and with optional liquid flow movement, the method provides stable colloids of dispersed metal and metal-alloy nanoparticles. In various embodiments additional stabilizing chemical agents are not required. | 08-05-2010 |
| 20110020170 | METAL NANOPARTICLES STABILIZED WITH DERIVATIZED POLYETHYLENEIMINES OR POLYVINYLAMINES - The invention relates to metal nanoparticles and a process for the preparation thereof, in which a metal salt solution is reduced with a reducing agent in the presence of the derivatized polyethyleneimines or polyvinylamines. Metal salt solutions of two or more different metals can be reduced simultaneously or in succession, metal nanoparticles comprising two or more different metals being obtained.

| 20160027547 | Ion Beam Modification of Noble Metals for Electrical Contacts - Ion beam modification of noble metal electrical contact coatings can achieve suitable friction and wear behavior with inherently stable low ECR. For example, this method of producing Au electrical contact coatings can produce wear properties similar to electroplated hard Au, but without the environmental concerns due to stringent OSHA regulations on the use and disposal of toxic chemicals associated with Au electroplating baths. Integration of physical vapor deposition techniques with ion implantation can produce noble metal coatings with surfaces modified to achieve the desired balance between adhesion/friction/wear and electrical contact resistance on a commercial scale. | 01-28-2016 |
| 20160138134 | PALLADIUM-BASED ALLOY - A palladium-based alloy including, expressed in weight, between 50 and 55% of palladium, between 45% and 50% of rhodium; a quantity x of silver where 0%≦x≦5%, and a quantity R of a balance including at least one element selected from among iridium, ruthenium, platinum, titanium, zirconium and rhenium and combinations thereof, where 0%≦R≦5%. The invention also relates to a A timepiece or piece of jewellery including at least one component made of such an alloy. | 05-19-2016 |
| 420465000 | Platinum containing | 3 |
| 20080232999 | Platinum-palladium alloy - An alloy for use in jewelry applications is provided that has a composition comprising about 45 to about 55 platinum by weight and about 55 to about 45 percent palladium by weight. The alloy possesses favorable characteristics as compared to pure platinum and pure palladium. Due to these characteristics, the alloy is attractive for use in jewelry applications. | 09-25-2008 |

An alternative embodiment includes palladium and rhenium and/or ruthenium with an additional element iridium, platinum, tungsten, boron, gold, zirconium, cobalt, nickel and tantalum. The present alloy family has a high strength, high radio opacity, and biocompatibility characteristics, while also being workable into various configurations.

| 20100266443 | Pd-Ag-Ga DENTAL ALLOYS WITH INTERNAL OXIDATION CHARACTERISTICS - A Pd—Ag alloy system that utilizes internal oxidation by including a base metal addition of only Ga is provided. The Pd—Ag—Ga alloy is particularly well-suited for use in porcelain-fused-to-metal (PFM) applications because the alloy does not form a dark oxide upon heating. The high oxygen potential of the material ensures the development of a tenacious chemical bond with the porcelain when used in PFM applications. Moreover, the addition of gallium lowers the liquidus temperature of the alloy to improve castability and strengthens the alloy significantly. | 10-21-2010 |
