Scientists in Sweden have developed a simple method to make the universe’s normally invisible binding forces visible by using gold flakes, salt water and light. The Chalmers University of Technology team created a platform that displays these tiny forces—often described as “nature’s invisible glue,” responsible for effects like dust sticking to surfaces or lizards climbing […]
Fancy photochemistry for next-gen displays
In this video, see how researchers at University of Colorado Boulder create thin-film holograms by using a rubbery substrate that allows monomer movement during laser writing, then add a curing step that locks the pattern in place by turning the film from rubbery to glassy.
