Researchers at Soochow University , Nanyang Technological University and the Beijing Institute of Technology recently carried out a study exploring the effects of surface roughness on the glass transition observed in elongated particles called colloidal ellipsoids.

Their paper, published in Physical Review Letters , shows that introducing tiny irregularities on the surface of these particles to increase their roughness can disrupt their transition into glass.
