This paper seeks to identify the factors which have the greatest effect on gas diffusion rates into animal burrows, and in turn on the maximum size of burrowing animals which may rely on simple burrow ...

Researchers have for the first time experimentally shown, almost a century later, an idea dating from 1912. In that year the physicist Smoluchowski devised a prototype for an engine at the molecular ...

Researchers were inspired by marinated eggs to demonstrate how diffusion works in an easy and quantifiable way. The basis of the recipe is marinating hard boiled eggs in vinegar or brine, which cures ...
