First evidence of anisotropic quenched disorder effects on a smectic liquid crystal confined in porous silicon [PDF]

open access: yes, 2005
We present a neutron scattering analysis of the structure of the smectic liquid crystal octylcyanobiphenyl (8CB) confined in one-dimensional nanopores of porous silicon films (PS). The smectic transition is completely suppressed, leading to the extension

Temperature fields in a channel partially filled with a porous material under local thermal non-equilibrium condition: an exact solution [PDF]

open access: yes, 2001
This work examines analytically the forced convection in a channel partially filled with a porous material and subjected to constant wall heat flux. The Darcy–Brinkman–Forchheimer model is used to represent the fluid transport through the porous material.
