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 ...

The study of molecular diffusion coefficients and their prediction models remains central to understanding mass transport across chemical and biological systems. Recent advances have sought to enhance ...

Gas transport through a metal cluster-containing crystalline solid. Hydrogen and carbon monoxide travel at different speeds due to their molecular size relative to the size of nanoscale tunnels in the ...
