DEVELOPMENTS AT NIST 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. NIST may enter into a Cooperative Research and Development Agreement (CRADA) with interested parties to perform further research on the invention for purposes of commercialization. NIST may grant CRADA Partners an option to negotiate for exclusive licenses to any jointly owned inventions which arise from the CRADA as well as an option to negotiate for exclusive royalty-bearing licenses for NIST employee inventions which arise from the CRADA. Anyone interested in the further development of any of these technologies or in applying for a license to commercialize these technologies shall send a written request for further information, referencing the NIST Docket Number and Title, to: 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: 97-044PA, Title: Multi-Wavelength Cross-Correlator for Ultrashort Radiation Pulses, Description: This invention is jointly owned by the U. S. Government, as represented by the Secretary of Commerce and the University of Colorado. The measurement of cross correlations and time delays between ultrashort laser pulses of widely different tunable wavelengths has been demonstrated in a greatly simplified device employing semiconductor photodiode materials. Two-color, two-photon induced photoconductivity in a commercial GaAsP photodiode is used for the first time to obtain femtosecond cross-correlation functions for different wavelength pairs. The invention requires no non-linear crystals, no phase matching and no separate detector, as is the case for conventional optical cross-correlation measurements. In the invention, zero time delays and accurate crosscorrelations were measured for 100 femtosecond laser pulses of dramatically different wavelengths, e.g. 775 nm and 1300 nm. The only restriction for applicable wavelengths is that the sum of the photon energies of the two incident laser beams is above the band gap energy of the semiconductor. NIST DOCKET NUMBER: 98-012PA, Title: Method for Fabricating Mono-Drystalline Step-Height Reference Materials for Certification by Means of High-Resolution Transmission-Electron Microscopy, Description: This invention is jointly owned by the U. S. Government, as represented by the Secretary of Commerce, and Sandia National Laboratories. The invention comprises a method for preparing single crystal step height artifacts on (100) silicon-on-insulator material using a selective etch process. The critical dimensions of the step height artifact can be calibrated and certified using High Resolution Transmission Electron Microscopy (HRTEM). Because the side wall slopes of the (100)(110) features are precisely defined, only two width measurements are needed to provide an estimation of the feature height. The bottom width of the feature may be determined using HRTEM, for example, and the top width may be determined electrically. Simple geometric considerations allow the determination of the feature height. NIST DOCKET NUMBER: 98-014, Title: Lubricant for Magnetic Hard Disks, Description: The disclosure describes partially and fully fluorinated fluorophenyl ester tail groups capped with chlorine as an improved lubricant for hard disks. These compounds provide longer chain hydrocarbon groups than conventionally used while maintaining fluidity. The higher molecular weight chlorine may also provide more effective anchoring of the molecular to the surface of the hard disk. The invention is available for commercial use without a license from NIST. WEB: NIST Contracts Homepage, http://www.nist.gov/admin/od/contract/contract.htm.
