The wave character of atoms can produce Casimir-like size effects in gases confined in a narrow box. Thus the pressure tensor is not isotropic anymore and size difference becomes a driving force for isothermal diffusion by a permeable wall. Such size effects give rise to "thermosize effects" similar to thermoelectric effects. (C) 2003 Elsevier B.V. All rights reserved.
