Researchers from Trinity College Dublin's School of Engineering have built a powerful new machine that lets us watch precisely what happens when tiny particles—far smaller than a grain of sand—hit a ...

Stewart Mallory, assistant professor of chemistry and chemical engineering at Penn State, leads a research group that studies active matter, specifically the collective behavior of self-propelled ...

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

Analyzing microplastics (MPs) in real environmental matrices requires the unambiguous identification of particles to distinguish them from particles of biogenic origin, such as particulate organic ...

Physicists show how microscopic particles can harness fluctuations and external forces to minimize transport energy and even extract usable work. A particle (red sphere) is guided from left to its ...

Scientists have built the world’s smallest engine. It consists of a single microscopic particle, smaller than a human cell, levitating in a vacuum. By rattling this lone particle with “noisy” ...

Scientists at King’s College London have built the world’s hottest engine—one so extreme that it reaches temperatures higher than the core of the sun. The engine isn’t a motor like you’d find in a car ...

A tiny, particle-sized engine that runs at temperatures approaching the innermost core of the Sun could open a window into the smallest extremes of thermodynamics. By levitating a single particle of ...

A new kind of microscope is giving scientists a way to watch life inside cells with a clarity that feels almost unfair. Instead of choosing between seeing big structures or tiny particles, researchers ...
