Imagine a liquid that flows freely one moment, then stiffens into a near-solid the next, and then can switch back with a simple change in temperature. Researchers at the University of Chicago Pritzker ...

Materials scientists are measuring the rolling friction of tiny, micrometer-sized particles. These measurements permit them to better understand everyday products such as concrete. For the first time, ...

A new computational analysis supports the idea that photons (a.k.a. particles of light) colliding with heavy ions can create a fluid of 'strongly interacting' particles. In a new paper, they show that ...

Granular matter is ubiquitous in nature and is present in diverse forms in important engineering, industrial and natural processes. Particle-based computational modelling has become indispensable to ...

A new computational analysis by theorists at the U.S. Department of Energy's Brookhaven National Laboratory and Wayne State University supports the idea that photons (a.k.a. particles of light) ...

The measuring tip of an atomic force microscope with a specially designed holder in which a spherical particle is “trapped”. Lacquers, paint, concrete—and even ketchup or orange juice: Suspensions are ...
