Spectroscopy-Based Tool Detects, Measures Contaminants in Landfills
SÃO CARLOS, Brazil, May 16, 2017 — A method known as laser induced breakdown spectroscopy (LIBS) could offer a cleaner, faster and simpler approach than existing technologies for detecting contaminants in the fluids coming from landfills. Although conventional LIBS presents some limitations when used in the single-pulse configuration, the use of LIBS in the double-pulse (DP) configuration demonstrated rapid detection of mercury (Hg) and could be applied to other contaminants. In LIBS, a sample is targeted with an intense
NASA Decides Not to Kill the MESSENGER
ANNAPOLIS, Md., Nov. 16, 2011 — NASA’s Messenger mission will live on for at least one year past its planned expiry date. The spacecraft entered orbit around Mercury, the solar system’s innermost planet, on March 18 this year, and its primary mission had been scheduled...
Vacuum Ultraviolet Luminescence Characterization System
CHELMSFORD, Mass., May 16, 2011 — McPherson Inc. has been contracted to build a characterization system that will help the Polish Academy of Science’s Institute of Low Temperature and Structure develop vacuum ultraviolet excitable phosphors. The benign discharge of a noble gas...
Sensors Map Planet’s Surface
May 1, 2011 — Onboard NASA’s Messenger, the first spacecraft to orbit the planet Mercury, CCD imaging sensors from e2v Technologies plc have captured new views of Mercury. The sensors were used in Messenger’s Mercury Dual Imaging System, which...
Navy Adopts LEDs on Ships and Submarines
ARLINGTON, Va., March 7, 2011 — A pilot program testing LED fixtures aboard several Navy ships and submarines is under way. The Solid State Lighting (SSL) project, created by the Office of Naval Research under its TechSolutions program, is one of several programs created...
Study Finds 'Eco-friendly' LEDs Are Toxic
IRVINE, Calif., Feb. 17, 2011 — Small LEDs found in holiday bulbs, traffic lights and car headlights and marketed as safe, environmentally preferable alternatives to traditional light bulbs actually contain lead, arsenic and a dozen other potentially hazardous substances,...
Surprising Gases in Moon Impact Plume
GREENBELT, Md, Oct. 26, 2010 — NASA's Lunar Reconnaissance Orbiter (LRO) and its sophisticated suite of instruments have determined that hydrogen, mercury and other volatile substances are present in permanently shaded soils on the Moon, according to a paper published in the Oct....
We = Rock (You)
Aug 30, 2010 — I’ve listened to “Radio Ga Ga” maybe a hundred times in the past couple of weeks. Sure, most music fans sniff at this 1984 Queen song, dismissing it as an excruciating low point in the band’s otherwise (mostly) distinguished...
‘Microscope’ to Examine Glass Phase
ST. LOUIS, March 24, 2010 – The National Science Foundation has awarded $1.65 million to a project led by physicist Ken Kelton of Washington University in St. Louis to build an electrostatic levitation chambe...
NSF Award for Deep UV LEDs
COLUMBIA, S.C, Feb. 12, 2010 – Sensor Electronic Technology Inc. (SETI), announced that is has been awarded a Phase II SBIR award from the National Science Foundation (NSF) for $500,000 to further advance its De...
An Artist’s Secrets? Projection and Photoluminescence
Sep 1, 2009 — More than 200 years before the camera was invented, Italian Renaissance artist Caravaggio (1571-1610) employed photographic techniques to develop his renowned light and shadow paintings, according to Roberta Lapucci, a teacher and researcher at...
Fluorescence Recycling Studied
Apr 20, 2009 — A study conducted by researchers at the University of Minnesota School of Public Health has found that most containers used for the storage and transportation of used fluorescent lamps to recycling centers do not provide adequate levels of...
A pocket sushi probe?
Apr 1, 2009 — Mercury is found in all sorts of things. From the fish we may eat to the fillings in our teeth, understanding just how much mercury is involved is important because of the potential health risks. To address this problem, a group at the University...
Bottoms Up: Zinc Oxide Glows
DURHAM, N.C., Dec. 18, 2008 -- A compound commonly used on babies' bottoms has been made to produce brilliant light best suited to the human eye. Duke University adjunct physics professor Henry Everitt, chemistry professor Jie Liu and their graduate student John Foreman...
Detecting Mercury with Gold
Feb 1, 2007 — As evidenced (albeit comically) by Lewis Carroll’s madcap hatter, mercury exposure can have serious health consequences, such as tremors, memory loss and personality changes. Free mercury can arise from volcanic emissions, the mining of precious...
Optical Atomic Clock Has Most Precise 'Ticks' Ever
BOULDER, Colo., Dec. 1, 2006 -- Using an ultrastable laser to manipulate strontium atoms trapped in a "lattice" of light, scientists at the National Institute of Standards and Technology (NIST) and the University of Colorado at Boulder have demonstrated the capability to produce...
Mercury Atomic Clock Keeps Time with Record Accuracy
BOULDER, Colo., July 20, 2006 -- An experimental optical clock that is based on a single mercury atom is more stable and accurate than the national standard atomic clock that uses a cloud of cesium atoms and would take about 400 million years to gain or lose one second, according...
Detector Contract Awarded
for ESA's Mercury Mission
PARIS, June 22, 2006 -- The European Space Agency (ESA) has awarded a contract to develop a new, near-infrared detector for the visible infrared imaging spectrometer (VN-IMS), a measurement instrument that will be used in BepiColombo, the ESA's mission to the planet...
RoHS Environmental Legislation Hits Hard
Apr 1, 2005 — The mercury in one compact fluorescent lightbulb may not pose much of a health hazard, but when all electronic parts are taken as a whole across the globe, the level of hazardous materials is monumental. But now, a directive legislated by the...
