Technique inspired by dolphin chirps could improve tests of soft materials

When you deform a soft material such as Silly Putty, its properties change depending on how fast you stretch and squeeze it. If you leave the putty in a small glass, it will eventually spread out like a liquid. If you pull ...

Âé¶¹ÒùÔºicists discover why drying liquid crystal drops leave unusual 'coffee rings'

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 ...
