Centrifugal pumps are critical components in many industrial applications requiring the transport of slurries – mixtures of solids suspended in a liquid. Their performance is strongly impacted by the ...

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, ...

Active matter: this microscope image shows part of a cluster of self-propelled particles, colour-coded according to their distance from the centre. (Courtesy: Jie Zhang, Ricard Alert, Jing Yan, Ned S ...

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