(Phys.org)—A team of researchers with the University of Côte d'Azur in France has found that drops ejected by an oscillating surface can at times travel faster than the surface that ejected them. In their paper published ...
In previous papers, University of Pennsylvania physicists investigated the "coffee ring effect," the ring-shaped stain of particles left after drops of coffee evaporate. In one paper, they learned how to undo this effect ...
