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 small team of physicists at the University of Amsterdam has demonstrated the ability of 3D-printed particles to propel themselves across the surface of a fluid, given the right fuel. The group has ...

In a twist on conventional wisdom, researchers have discovered that in ocean-like fluids with changing density, tiny porous particles can sink faster than larger ones, thanks to how they absorb salt.

Cancer claims more than 10 million lives every year globally. Research shows that detecting cancer early can greatly improve a patient’s chance of survival. And yet we lack reliable, affordable tools ...

Sitting in a restaurant, you reach for the ketchup bottle, eyeing the basket of fries in front of you. You give the bottle a ...

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 ...
