News: Complex Materials and Processing
A team of Princeton researchers found they could coat a liquid elastic on the outside of a disc and spin it to form useful, complex patterns. When spun just right, tiny spindles rise from the material as it cures. The spindles grow as the disc accelerates, forming a soft solid that resembles hairs.
In research that may eventually help crops survive drought, scientists at Princeton University have uncovered a key reason that mixing material called hydrogels with soil has sometimes proven disappointing for farmers.
