Researchers use earthworms to create quantum dots
Nanoscale nonlinear light source created
Not long after the development of the first laser in 1960 scientists discovered that shining a beam through certain crystals produced light of a different color; more specifically, it produced light of exactly ...
Single Green Fluorescent Protein-expressing cell is basis of living laser device
(PhysOrg.com) -- It sounds like something out of a comic book or a science fiction movie a living laser but that is exactly what two investigators at the Wellman Center for Photomedicine at Massachusetts ...
Vibrations key to efficiency of green fluorescent protein
University of California, Berkeley, chemists have discovered the secret to the success of a jellyfish protein whose green glow has made it the darling of biologists and the subject of the 2008 Nobel Prize ...
Tiny lasers plug the 'green gap'
(PhysOrg.com) -- Compact lasers which can work in formerly inaccessible parts of the spectrum and are suitable for mass production are now within reach.
How NASA builds a space laser
To build a satellite that will measure all the bumps and dips of our dynamic Earth, engineers started with a black box, built of a composite honeycomb material to make it as light as possible.
Chemists demonstrate nanoscale alloys so bright they could have potential medical applications
(Phys.org) —Alloys like bronze and steel have been transformational for centuries, yielding top-of-the-line machines necessary for industry. As scientists move toward nanotechnology, however, the focus ...
Nanodot-based memory sets new world speed record
Record speed, low-voltage, and ultra-small size make nanodots a "triple threat" for electronic memory in computers and other electronic devices.
Using high-precision laser tweezers to juggle cells
Researchers at the University of Gothenburg, Sweden, have developed a new method to study single cells while exposing them to controlled environmental changes. The unique method, where a set of laser tweezers ...
A look at the hazards of green laser pointers
Those handheld green lasers pointers may not be as harmless as you thought.
NIST tests underscore potential hazards of green laser pointers
Using a low-cost apparatus designed to quickly and accurately measure the properties of handheld laser devices, National Institute of Standards and Technology (NIST) researchers tested 122 laser pointers ...
New research embraces laser and sparks cool affair
Bulky and noisy air-conditioning compressors and refrigerators may soon be a thing of the past. With the latest discovery by scientists from Nanyang Technological University (NTU), current cooling systems ...
Researchers measure high infrared power levels from some green lasers
Green laser pointers have become a popular consumer item, delivering light that's brighter to the eye than red lasers, but stories have circulated on the Web about the potential hazards of inexpensive models. ...
Iowa State engineer and Goodrich partner to develop next-generation fuel nozzle diagnostic systems
A green laser flashed across the high-pressure spray that fuels a jet engine. Those flashes, some just 50 millionths of a second apart, froze the droplets for a camera to record and a computer to analyze.
