How does a cloud stay cool under direct sunlight—or seem to vanish in infrared? In nature, phenomena like white cumulus clouds, gray storm systems, and even the hollow hairs of polar bears offer remarkable lessons in balancing ...
Blink and you might miss it, but if you keep your eye on the monitors in professor Sebastian Will's lab, you'll catch a series of single-second flashes that light up the screen. Each flash is an atom of strontium, a naturally ...
Optical biosensors use light waves as a probe to detect molecules, and are essential for precise medical diagnostics, personalized medicine, and environmental monitoring.
A new filter for infrared light could see scanning and screening technology tumble in price and size. Built on nanotechnology, the new heat-tunable filter promises hand-held, robust technology to replace current desktop infrared ...
Color, as the way light's wavelength is perceived by the human eye, goes beyond a simple aesthetic element, containing important scientific information like a substance's composition or state.
Physicists at ETH Zurich have developed a lens that can transform infrared light into visible light by halving the wavelength of incident light. The study is published in Advanced Materials.
In the nanometer range (billionth of a meter), interactions occur between light and matter that do not happen on larger scales. As such, so-called nanophotonic materials have unique optical properties that open up a whole ...
Metalenses represent a revolutionary advancement in optical technology. Unlike conventional microscope objectives that rely on curved glass surfaces, metalenses employ nanoscale structures to manipulate light at the subwavelength ...
Augmented reality (AR), the technology that overlays digital content onto what users see around them in real-time, is now widely used in the retail, gaming and entertainment industries, as well as in some educational settings ...
By carefully placing nanostructures on a flat surface, researchers at Linköping University, Sweden, have significantly improved the performance of so-called optical metasurfaces in conductive plastics. This is a major step ...
