Initially stacked benzene layers increase fluorescent color change drastically when exposed to pressure, suggesting new ways to design the pressure sensors used in machinery and medical devices.

Scientists have created a new light-activated ink that can change color on demand. It’s made up of microbeads of different colors that rise or sink in response to different wavelengths of light so ...

Squeezing the crystal changes how closely the molecules interact, which changes the color of light it emits from green at low pressure (left) to red at high pressure (right). In pCP-H (lower crystals) ...
