When a viscous fluid, such as a jar of honey, is stirred and then unstirred, the contents return to their starting points. However, according to research by a team of physicists headed by New York ...

Accurately modeling irregularly-shaped particles isn’t easy, but a new study found a way to improve a century-old idea.

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 ...

It is commonly assumed that tiny particles just go with the flow as they make their way through soil, biological tissue, and ...

Imagine a "smart fluid" whose internal structure can be rearranged just by changing temperature. In a new study published in ...

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 ...

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 ...

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 ...

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