Abstract

Diffusion has a history in science of more than one and a half centuries (Philibert, 2005, 2006). Driven by the experimental observation of the German chemist Johann Döbereiner in 1823 that hydrogen gas diffuses faster than air, in the late 1820s and early 1830s the Scottish chemist Thomas Graham performed a systematic study on diffusion in gases and found that the rate of gas diffusion is inversely proportional to the square root of its molecular mass (Sherwood et al., 1971).
