Colorful math reveals how forces transmit through granular materials

Using color-changing plastic cylinders as a stand-in for a mass of granular material, Duke University physicists have created a computer-testable method to predict, particle-by-particle, how pushes, nudges and shoves at the ...

Electric-Field-Induced Phase-Separation of Liquid Mixtures

Researches have shown that electric fields can control the phase separation behaviour of mixtures of simple liquids under practical conditions, provided that the fields are non-uniform. This direct control over phase separation ...
