Laser Pointers Are Still Dangerous: NIST
2013-03-21 04:56:06

April Flowers for redOrbit.com - Your Universe Online Researchers from the National Institutes of Standards and Technology (NIST) recently demonstrated a low-cost apparatus designed to quickly and accurately measure the properties of 122 commercially available handheld laser pointers. The scientists found that nearly 90 percent of green laser pointers and approximately 44 percent of red laser pointers were out of compliance with federal safety regulations. The NIST test apparatus was...

The National Institute of Standards and Technology (NIST) has demonstrated a novel chip-scale instrument made of carbon nanotubes that may simplify absolute measurements of laser power, especially the light signals transmitted by optical fibers in telecommunications networks. The prototype device, a miniature version of an instrument called a cryogenic radiometer, is a silicon chip topped with circular mats of carbon nanotubes standing on end. The mini-radiometer builds on NIST's previous...

A cornerstone of physics may require a rethink if findings at the National Institute of Standards and Technology (NIST) are confirmed. Recent experiments suggest that the most rigorous predictions based on the fundamental theory of electromagnetism–one of the four fundamental forces in the universe, and harnessed in all electronic devices–may not accurately account for the behavior of atoms in exotic, highly charged states. The theory in question is known as quantum...

Scientists Image The Molecular Structure Of Polymer Blends
2012-11-28 15:30:26

National Institute of Standards and Technology (NIST) Using an enhanced form of "chemical microscopy" developed at the National Institute of Standards and Technology (NIST), researchers there have shown that they can peer into the structure of blended polymers, resolving details of the molecular arrangement at sub-micrometer levels. The capability has important implications for the design of industrially important polymers like the polyethylene blends used to repair aging waterlines....

Study Suggests Carbon Nanotubes May Protect DNA From Oxidation
2012-11-15 14:01:10

National Institute of Standards and Technology (NIST) Researchers at the National Institute of Standards and Technology (NIST) have provided evidence in the laboratory that single-wall carbon nanotubes (SWCNTs) may help protect DNA molecules from damage by oxidation. In nature, oxidation is a common chemical process in which a reactive chemical removes electrons from DNA and may increase the chance for mutations in cells. More studies are needed to see if the in vitro protective effect of...

Researchers at the National Institute of Standards and Technology (NIST) have developed a new computational method for identifying candidate refrigerant fluids with low "global warming potential" (GWP) – the tendency to trap heat in the atmosphere for many decades – as well as other desirable performance and safety features. The NIST effort is the most extensive systematic search for a new class of refrigerants that meet the latest concerns about climate change. The new method...


Word of the Day
cruet
  • A vial or small glass bottle, especially one for holding vinegar, oil, etc.; a caster for liquids.
This word is Middle English in origin, and ultimately comes from the Old French, diminutive of 'crue,' flask.
