Recycling facilities collect glass and mercury from thrown-away fluorescent bulbs, but discarded lighting could also supply rare-earth metals for reuse. The 17 metals referred to as rare earths aren't all widely available ...
The widely used dry-cleaning and degreasing solvent perc can be converted to useful chemicals by a new, clean, safe, and inexpensive procedure. The Kobe University discovery using on-demand UV activation may open the path ...
Infectious diseases pose a huge problem in poultry farming. Poultry farmers are often forced to rely on antibiotics to tackle this issue. However, this can sometimes result in germs developing resistance to these drugs. These ...
Light pollution ruins dark skies. It's a scourge that ground-based observatories have to deal with in one form or another. Scientists used a small observatory in Japan to measure what changed when a nearby town improved its ...
Integrated optical signal distributing, processing, and sensing networks require the miniaturization of basic optical elements, such as waveguides, splitters, gratings, and optical switches. To achieve this, fabrication approaches ...
A new publication in Opto-Electronic Science reports how high-quality diamonds empower narrowband deep ultraviolet photodetection.
As an engineering plastic having high transparency and impact resistance, polycarbonate (PC) is employed in eyeglass lenses, camera lenses, DVDs, automobile headlights and bulletproof glass.
Bacterial biofilms are clusters of microorganisms that form on wetted surfaces virtually everywhere. They harbor pathogens that compromise water quality, and they can disrupt the operation of many different engineered systems ...
Tourists reveled in wintry scenes across Japan on Wednesday, as much of the country was blanketed by snow in a cold snap that has killed at least one person and disrupted travel.
Many photochemical processes rely on UV light from inefficient or toxic light sources that the LED technology cannot replace for technical reasons. An international team of scientists led by Professor Christoph Kerzig of ...
