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 ...

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 ...

The drainage and imbibition processes are critical mechanisms in petroleum engineering. These processes in a porous medium are controlled by surface forces and pressure gradients. The study of these ...

Nanorobotic swarming concentrates photothermal particles into heat-retaining clusters, helping the same material outperform ...

Magnetic fluids, suspensions of magnetic particles in carrier liquids like water, oil or organic solvents, combine magnetic properties with fluidity to achieve features such as rapid magnetic response ...

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 ...

Scientists didn’t understand why independently oscillating microscopic particles suddenly begin moving in perfect sync when grouped together. Researchers showed that fluid-driven hydrodynamic ...

If you mix cornstarch and water in the right proportions, you get “oobleck”: something that seems not-quite-liquid but also not-quite-solid. Oobleck flows and settles like a liquid when untouched, but ...

To melt a solid, heat it. To freeze a liquid, cool it. It's simple—except when it isn't, because quantum mechanics can flip even the intuitive logic of melting and freezing on its head. Physicists ...

Microplastics and the much smaller nanoplastics enter the human body in various ways, for example through food or the air we breathe. A large proportion is excreted, but a certain amount remains in ...
