How diamond nanoparticles could be the trick for clothes that keep you cool in extreme heat

Tiny diamond particles can help fabric release heat—and despite being diamonds, they’re surprisingly affordable to make.

On a hot day, most clothing traps heat. But fabric coated with nanodiamonds—tiny diamond particles—can instead release heat, helping cut energy use for air-conditioning.

The diamond nanoparticles, each less than one-thousandth of the width of a human hair, have the same carbon crystal structure as larger diamonds. But since they don’t have to be perfectly formed and can be made from carbon waste such as plastic, they are relatively inexpensive to make. The structure means........
