An international team led by researchers at Penn State and Université Paris-Saclay has gained precise control over light emitted from nanoscale sources embedded in two-dimensional (2D) materials. This ...

A week or so ago, I got a question on Facebook that was relayed from one of the kids of a college friend, which I'll paraphrase as "What's the physics explanation of what gives objects their color?" ...

How does color work, and how does the type of light source you use affect the colors you see? Appliance Science looks at the science of light and color. Richard Baguley Richard Baguley has been ...

The invention of tiny devices capable of precisely controlling the direction and behavior of light is essential to the ...

Focused laser-like light that covers a wide range of frequencies is highly desirable for many scientific studies and for many applications, for instance, quality control of manufacturing semiconductor ...
