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, ...

Engineers at Northwestern University have unveiled the behavior of single microscopic particles when they unite. The findings reveal an enigmatic, perfectly synchronized dance. The research team ...

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 ...

Egg yolk may appear runny and uniform, but on the nanoscale, it is one of the most crowded biological fluids in nature.

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 ...

Microplastics have been found almost everywhere that scientists have looked for them. Now, according to research published in the ACS partner journal Environment & Health, these bits of plastic — from ...
