Innovation — construction drip by drip

Researchers simplify tiny structures' construction drip by drip Princeton University, Engineering School IMAGE: Shown are three lab samples in descending size. The rings were cured in a centrifuge using acceleration to control the length scale of the droplet structures, which can be used. Credit: Pierre-Thomas Brun Popping the top on house paint usually draws people to look inside the can. But Princeton researchers have turned their gaze upward, to the underside of the lid, where it turns out that pattern of droplets could inspire new ways to make microscopically small structures. The trick comes in controlling the droplets, which form under...
