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 ...

In a recent study published in Science Advances, an international team of researchers led by Northwestern University have developed a method to trap rolling microparticles in fluid using obstacles ...

Lacquers, paint, concrete—and even ketchup or orange juice: Suspensions are widespread in industry and everyday life. By a suspension, materials scientists mean a liquid in which tiny, insoluble solid ...

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 ...
