Identifying a new, cleaner source for white light
When early humans discovered how to harness fire, they were able to push back against the nightly darkness that enveloped them. With the invention and widespread adoption of electricity, it became easier to separate heat from light, work through the.....»»
Millions of people across the US use well water, but very few test it often enough to make sure it"s safe
About 23 million U.S. households depend on private wells as their primary drinking water source. These homeowners are entirely responsible for ensuring that the water from their wells is safe for human consumption......»»
Researchers develop a laser that produces the strongest ultra-short laser pulses to date
The word laser usually conjures up an image of a strongly concentrated and continuous light beam. Lasers that produce such light are, in fact, very common and useful. However, science and industry often also require very short and strong pulses of la.....»»
Finely regulated luminescent Ag-In-Ga-S quantum dots with green-red dual emission toward white LEDs
Semiconductor quantum dots (QDs) materials have shown great potential for applications in lighting and display fields due to their wide color gamut, adjustable emission wavelength, high quantum efficiency, high color saturation, and low processing co.....»»
Powerful and compact optical frequency combs provide unique opportunities
Remember those big, clunky machines needed for super precise light measurements? Those days are fading thanks to tiny devices called microcombs. These chips can do the same job, but on a much smaller scale, opening doors for new applications......»»
Intra-molecular distances in biomolecules measured optically with Ångström precision
A team led by physicists Steffen Sahl and Stefan Hell at the Max Planck Institute (MPI) for Multidisciplinary Sciences in Göttingen and the MPI for Medical Research in Heidelberg has succeeded in measuring distances within biomolecules using a light.....»»
Scientists use light to visualize magnetic domains in quantum materials
When something draws us in like a magnet, we take a closer look. When magnets draw in physicists, they take a quantum look. Scientists from Osaka Metropolitan University and the University of Tokyo have successfully used light to visualize tiny magne.....»»
A quantum material could be the future of high-energy X-ray imaging and particle detection
Scintillators are detectors that make high-energy X-rays or particles visible through flashes of light to form an image. Their many applications include particle physics, medical imaging, X-ray security and more......»»
