Study Provides Unprecedented Details On Ultrafast Processes In Diamond Nitrogen Vacancy Centers
2013-11-04 16:26:12

Lawrence Berkeley National Laboratory From supersensitive detections of magnetic fields to quantum information processing, the key to a number of highly promising advanced technologies may lie in one of the most common defects in diamonds. Researchers at the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have taken an important step towards unlocking this key with the first ever detailed look at critical ultrafast processes in these...

Crime-scene investigators may soon have a new tool to help them catch evildoers. Researchers have demonstrated the proof-of-principle for a new forensic technique to identify individual fibers of cloth, which often all look alike. "White cotton fibers are so common and have so few visual distinguishing features that they are largely ignored by forensic scientists at crime scenes," says Brian Strohmeier, a scientist at Thermo Fisher Scientific, a laboratory-instrument company based in...

Seeing In The Dark With Novel Infrared Remote Sensing System
2013-10-29 14:33:32

American Institute of Physics Thermal infrared (IR) energy is emitted from all things that have a temperature greater than absolute zero. Human eyes, primarily sensitive to shorter wavelength visible light, are unable to detect or differentiate between the longer-wavelength thermal IR "signatures" given off both by living beings and inanimate objects. While mechanical detection of IR radiation has been possible since Samuel Pierpont Langley invented the bolometer in 1880, devices that also...

Xtalks presents an exciting live webinar on Friday October 18, 2013 at 1:00 pm EDT on the expanding the role of NMR beyond structure identification. Toronto, Canada (PRWEB) October 11, 2013 Nuclear magnetic resonance (NMR) spectroscopy is widely recognized as an extremely information-rich analytical technique. In the pharmaceutical industry, the utility of NMR is expanding beyond its traditional role as a tool for studying molecular structures and dynamics. At the same time, regulatory...

Flawed Diamonds Are Gems For New Technology

University of Arizona Using ultra-fast laser pulses, researchers have made the first detailed observation of how energy travels through diamonds containing nitrogen-vacancy centers -- promising candidates for a variety of technological advances such as quantum computing A team of researchers led by University of Arizona assistant professor Vanessa Huxter has made the first detailed observation of how energy travels through diamonds that contain nitrogen-vacancy centers – defects in...

Opal-Based Breathalyzer Being Developed
2013-10-09 05:05:26

redOrbit Staff & Wire Reports - Your Universe Online A team of Italian researchers are hoping to make catching drunk drivers easier and less expensive for police officers by developing a new portable breathalyzer capable of testing for precise alcohol concentrations. Their research, which appears in Tuesday’s edition of The Optical Society's (OSA) journal Optical Materials Express, describes a new portable device that would change colors from green to red when it detected higher...

Naked Jets Of Water Is A Better Way To Detect Pollutants
2013-10-04 06:53:40

Optical Society Novel design for microfluidic sensor uses streams of unconfined water for a simpler and cheaper way to test for dangerous chemicals and bacteria When you shine ultraviolet light (UV) through water polluted with certain organic chemicals and bacteria, the contaminants measurably absorb the UV light and then re-emit it as visible light. Many of today’s more advanced devices for testing water are built to make use of this fluorescent property of pollutants; but the walls...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'karpos', fruit.
