WASHINGTON, Dec. 5 -- President Bush signed the 21st Century Nanotechnology Research and Development Act into law this week, authorizing funding for nanotechnology research and development (R&D) over four years, starting in fiscal year 2005. The legislation puts into law programs and activities supported by the National Nanotechnology Initiative (NNI), one of the President’s highest multi-agency R&D priorities. The new law specifies a major role for the National Institute of Standards and Technology (NIST). It requires the director of NIST to "establish a research program on the development...Read full articleRelated content from Photonics MediaArticlesStartup Details Plans to Commercialize Sandia’s Ultrafast X-Ray TechSandia National Laboratories has partnered with Albuquerque, N.M.-based startup Advanced hCMOS Systems to commercialize ultrafast x-ray imaging technology invented at the labs and used extensively in...Vision-Spectra.com March 2023 IssueMetrology Center Adds to Growing Dutch Photonics EcosystemThe Netherlands’ Photonic Integration Technology Center (PITC) has launched a dedicated metrology program, aimed at developing design-for-test methodologies and new product characterization and...Photonics Spectra February 2023 IssueJoint Research Lab for Smart Glasses to Launch With $50M InvestmentPolitenico di Milano and Milan-based lens technology and eyewear manufacturer EssilorLuxottica will establish a joint smart eyewear lab, aimed at designing smart glasses technology.
