UNBINDING OF SURFACE DEFECTS UNDER THE DEFECT-SELECTIVE ADSORPTION

Condensed Matter Physics, 2003
Unbinding of surface topological defects in the presence of the defect-selective adsorption is investigated using a coupled Coulomb Gas - Lattice Gas model. The unbinding temperature increases with the increasing selectivity (and coverage) for both, sign-

Synthesis, characterisation and gas permeation studies on microporous silica and alumina-silica membranes for separation of propane and propylene [PDF]

, 1996
Microporous silica membranes are known to exhibit molecular sieving effects. However, separation of nearly equal sized molecules is difficult to carry out by size exclusion.

Simulation study of a rectifying bipolar ion channel: Detailed model versus reduced model

Condensed Matter Physics, 2016
We study a rectifying mutant of the OmpF porin ion channel using both all-atom and reduced models. The mutant was created by Miedema et al. [Nano Lett., 2007, 7, 2886] on the basis of the NP semiconductor diode, in which an NP junction is formed.
