Tiny particles are opening big doors for medicine, materials science, and even environmental cleanup. Across the world, scientists are racing to understand how these microscopic swimmers behave, ...

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 ...

In reliability engineering, few indicators are as consistently revealing as the particles that infiltrate a lubrication ...

Researchers at the University of Pennsylvania and the University of Michigan have built the smallest fully programmable autonomous robots ever ...

Gears have powered the world for millennia, from clock machines to car engines. But miniaturizing them to microscopic dimensions has stumped engineers for decades. Anything under one-tenth of a ...

Scientists at ETH Zurich have developed a new approach for targeted drug delivery inside the human body. They have created tiny particles that can carry medicines directly to their intended ...

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 ...
