TECHNOLOGY TRANSFER OPPORTUNITY POC Marcia Salkeld (301) 975-4188 Researchers at the National Institute of Standards and Technology (NIST) have developed a number of new devices and methods involving a variety of technologies. In certain cases other parties have participated in the development of these technologies. Anyone interested in the further development of any of these technologies or in applying for a license to commercialize these technologies should send a written request for further information, referencing the NIST Docket Number and Title, to: Marcia Salkeld, National Institute of Standards and Technology, Industrial Partnerships Program, Building 820, Room 213, Gaithersburg, Maryland 20899; Telecopy: 301-869-2751. This is not an announcement of a contract action or a grant. NIST Docket Number: 95-048D; Title: Methods for Welding Cryogenic Alloys; Description: To weld metal parts intended for exposure to cryogenic temperatures, an austenitic welding electrode of nickel, chromium, molybdenum, manganese, nitrogen, and iron in specified amounts is used. This alloy and welding method form a weld metal with a superior tearing modulus, fracture toughness, and yield strength at temperatures of about 77 K to as low as 4 K. NIST Docket Number: 96-016PA; Title: Synthesis of Fine-power Polycrystalline Bi-Se-Te, Bi-Sb-Te, and Bi-Sb-Se-Te Alloys for Thermoelectric Applications; Description: Precursors to alloys having the general compositions Bi-Se-Te, Bi-Sb-Te, and Bi-Sb-Se-Te are synthesized by aqueous coprecipitation and metal-organo complex methods. Hydrogen reduction of the precursors produces the alloys in fine-powder, polycrystalline form. The method is simpler than conventional melt processing and produced an 88-92% yield in laboratory-scale tests.
