Researchers at The University of Osaka, in collaboration with ULVAC, Inc. and Ritsumeikan University, have developed a new LED structure that generates circularly polarized light from a single chip.

It is also available in a variety of alternative configurations, such as with a taller floor-mounted tripod, for a little ...

From 3D movie screens to augmented-reality devices, many modern technologies rely on our ability to manipulate light. Doing so in a cost-effective and efficient way, however, is often a formidable ...

Abstract: Three-dimensional (3D) perovskite with good charge transport and structural stability, showing application potential in light-emitting diodes (LED). However, the grain size of 3D perovskite ...

If you’re shopping for a flashlight, you may think looking at how many lumens it puts out is the best way to determine quality or usefulness. It’s an understandable assumption, but that number in ...

Cars' headlights have come a long way since charming yet potentially dangerous acetylene headlamps debuted in vintage automobiles. The later halogen headlights are still around, but the world has ...

Cancer treatment has come a long way, but many of today’s therapies still come with steep costs: not just financial, but physical and emotional too. Chemotherapy and radiotherapy remain vital tools, ...
