You dip your teabag into a cup of boiling water and watch the clear steaming liquid slowly change into an inviting rich red. The laws by which the particles of tea spread from the source of high ...

Egg yolk may appear runny and uniform, but on the nanoscale, it is one of the most crowded biological fluids in nature. Packed with proteins and fats, it serves as a dense storage reservoir for a ...

Brownian motion, the incessant random movement of microscopic particles driven by thermal fluctuations, plays a pivotal role in particle transport within porous media. Porous materials, characterised ...

Neutral particles can outpace diffusion in electric fields, shifting motion regimes over time; the model predicts behavior in ...

It is commonly assumed that tiny particles just go with the flow as they make their way through soil, biological tissue, and other complex materials. But a team of Yale researchers led by Professor ...

Researchers have figured out how to create a gas that, when cooled to freezing temperatures, will not experience resistance or diffusion. The atoms in this gas do not abide by the usual ballistic or ...
