Researchers developed a color-changing material that alters both surface texture and appearance in seconds, inspired by ...

Liquid crystals, fluids with aligned phases of constituent molecules, are used in everything from computer and television displays to mood rings. Since liquid crystals are made of rod-like molecules, ...

To control color, the team sandwiched the polymer between two gold films. Light bounces off these films and interferes in ...

Diverging and converging patterns forming on the surface of solidifying liquid metals resemble plotlines in a complex historical novel, in a new international study. The cyclic patterns observed are ...

A team of physicists has pulled off a visual trick that sounds like stage magic: they made a flash of light vanish inside a ...
