A research team has discovered a unique quantum state at the interface between organic materials and two-dimensional ...

Abstract: It is well known that inclined sidewall scattering structures can improve the light extraction efficiency (LEE) of micro deep ultraviolet (DUV) light-emitting diodes (LEDs). However, ...

Dermatologists explain the science behind wildly popular treatments like red light therapy, which is now available at home—for a steep price. Full-face LED masks like this one can cost up to several ...

Small household appliances with electric heating coils and brushed DC motors—such as hairdryers, toasters and air fryers—are significant sources of ultrafine particles (UFP) that may pose health risks ...

African forests are now emitting more carbon dioxide than they absorb, a fundamental shift that will make it more difficult for the world to cut its net emissions to zero. Forests and shrubby ...

Photonic quantum processors, devices that can process information leveraging quantum mechanical effects and particles of light (photons), have shown promise for numerous applications, ranging from ...

We might tend to take the word “diode” for granted if we’re thinking of a “diode” as just a two-lead or two-terminal device that gets used in this or that place for this or that purpose. It can become ...

This illustration depicts the QAO family dopant integrated into the organic light-emitting diode structure. By designing a molecule with a lower HOMO level than that of the host material, the ...

Interstellar object 3I/ATLAS — which is zooming through our inner solar system — appears to be emitting its own light, according to Harvard astrophysicist Avi Loeb. The observation by Loeb, if ...

Last month, astronomers made an exciting discovery, observing an interstellar object — only the third ever observed — hurtling toward the center of the solar system. The object, dubbed 3I/ATLAS, has ...

Wearable electronics have evolved from basic fitness trackers to sophisticated health-monitoring systems, demanding light-emitting devices that balance visual quality, power efficiency, and mechanical ...
