From targeted cancer treatments to self-healing materials and microscopic robots, many emerging technologies depend on ...

How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...

Molecular antennae boost the visible-light sensitivity of azobenzene photoswitches while preserving switching efficiency and thermal stability.

Light takes time to travel, which means any telescope powerful enough to see far enough away is also looking backward in time ...

Researchers have created visible lasers of very pure colors from near-ultraviolet to near-infrared that fit on a fingertip. The colors of the lasers can be precisely tuned and extremely fast -- up to ...

Engineers have invented a breakthrough optical phase modulator that controls visible light -- without dimming it -- with the smallest footprint and lowest power consumption. New device will improve ...

Seven different vials are shown against a black background, each glowing a different color. From left to right, the vials are red, orange, yellow, green, blue, purple, and magenta. Quantum dots are ...

Two independent research groups now report for the first time that visible light can break apart PFAS into benign by-products (Nature 2024, DOI: 10.1038/s41586-024-08179-1 and 10.1038/s41586-024-08327 ...

Chemists have built a microscopic hollow shell that behaves a little like a living cell, taking in raw ingredients and ...
