Diffusion coefficients in supercritical fluids are critical parameters that characterise mass transport within these unique media. Owing to the tunable density and solvent power of supercritical ...

Proceedings of the Royal Society of London. Series A, Mathematical and Physical Sciences, Vol. 222, No. 1148 (Feb. 23, 1954), pp. 109-118 (10 pages) For diffusion into a solid from a gas or a liquid ...

This paper is concerned with the problem of estimation for the diffusion coefficient of a diffusion process on R, in a non-parametric situation. The drift function can be unknown and considered as a ...
