A hidden hazard lurks beneath many of the roughly 156,000 gas stations across the United States. Corrosion in parts of underground gas storage tanks that could result in failures, leaks and contamination of groundwater, a source of drinking water. In recent years, field inspectors in nine states have reported many rapidly corroding gas storage tank components such as sump pumps. These incidents are generally associated with use of gasoline-ethanol blends and the presence of bacteria that convert ethanol to acetic acid. A NIST study has documented severe corrosion on steel alloy samples exposed to ethanol and acetic acid vapors. | | |  Readying Your Community to Deal with Disaster
This week, experts are meeting at the New Jersey Institute of Technology in Hoboken to discuss how communities can prepare themselves to minimize the impacts of major disasters like Hurricane Sandy, the 2012 "superstorm", and quickly restore vital functions and services. In a post on The Commerce Blog, Stephen Cauffman, NIST's lead researcher for disaster resilience writes about NIST's effort to provide tools and guidance to help U.S. communities become more disaster resilient. | | |  Latest NIST Mass Spectral Library: Expanded Coverage, Features
The world's most widely used and trusted resource for identifying mass spectra, the "fingerprints" of molecules, has undergone a major expansion, according to NIST. The newest edition of the NIST/EPA/NIH Mass Spectral Library boasts significantly increased coverage within each of its three components: the NIST/EPA/NIH Mass Spectral Library of electron ionization (EI) spectra, the NIST Tandem Mass Spectral Library, and the NIST Library of GC Methods and Retention Index Data. | | |  Enhanced NIST Instrument Enables High-speed Chemical Imaging of Tissues
A NIST research team working with the Cleveland Clinic has demonstrated a dramatically improved technique for analyzing biological cells and tissues based on characteristic molecular vibrations. The new technique is an advanced form of Raman spectroscopy that delivers signals that are 10,000 times stronger than spontaneous Raman scattering, and 100 times stronger than comparable instruments. It's fast and accurate enough to create high-resolution images of biological specimens, with detailed spatial information on specific biomolecules, at speeds fast enough to observe changes in living cells. | | |  'Comb on a Chip' Powers New NIST/Caltech Atomic Clock Design
NIST and CalTech researchers have demonstrated a novel design for a small atomic clock that is based on a chip-scale frequency comb, or a microcomb. The new clock architecture might eventually be used to make portable tools for calibrating frequencies of advanced telecommunications systems or providing microwave signals to boost stability and resolution in radar, navigation and scientific instruments. | | |  NIST Shows Ultrasonically Propelled Nanorods Spin Dizzyingly Fast
Vibrate a solution of rod-shaped metal nanoparticles in water with ultrasound and they'll spin around their long axes like tiny drill bits. Why? No one yet knows exactly. But NIST researchers have clocked their speed, and it's fast. At up to 150,000 revolutions per minute, ten times faster than any nanorotor ever reported. | | |  Fill 'er Up: NIST Develops Prototype Meter Test for Hydrogen Refueling Stations
To support the fair sale of gaseous hydrogen as a vehicle fuel, NIST researchers have developed a prototype field test standard to test the accuracy of hydrogen fuel dispensers. Once the standard is field tested, it will serve as a model for constructing similar devices for state weights and measures inspectors to use. | | |  NIST, HHS Sponsor 7th Annual Conference on Healthcare Information Security
The seventh annual "Safeguarding Health Information: Building Assurance through HIPAA Security" conference will be held September 23-24, 2014, in Washington, D.C. The meeting is co-hosted by NIST and the Department of Health and Human Services' Office for Civil Rights (OCR). |
