2005 journal article

Adsorption of Simple Gases in MCM-41 Materials: The Role of Surface Roughness

LANGMUIR, 22(1), 194–202.

By: B. Coasne*, F. Hung*, R. Pellenq*, F. Siperstein* & K. Gubbins* 

TL;DR: Comparison with adsorption and neutron scattering experiments suggests that model B is too rough at the molecular scale but reproduces reasonably the surface disorder of real MCM-41 at larger length scales, while model A is smooth at small length scales in agreement with experiments but seems to be too ordered at large length scales.

2005 journal article

Cosurfactant and cosolvent effects on surfactant self-assembly in supercritical carbon dioxide

JOURNAL OF CHEMICAL PHYSICS, 122(9).

By: N. Chennamsetty n, H. Bock n, L. Scanu n, F. Siperstein n & K. Gubbins n 

TL;DR: The impact of alcohol additives on the self-assembly of surfactants in supercritical carbon dioxide is investigated using lattice Monte Carlo simulations, observing that all studied (model) alcohols reduce the critical micelle concentration and short-chain alcohols act as cosurfactants, directly influencing the properties of the aggregates.

2005 journal article

Molecular modeling of freezing of simple fluids confined within carbon nanotubes

JOURNAL OF CHEMICAL PHYSICS, 122(14).

By: F. Hung*, B. Coasne*, E. Santiso* , K. Gubbins* , F. Siperstein* & M. Sliwinska-Bartkowiak *

TL;DR: The simulations show evidence of a rich phase behavior in confinement; a number of phases, some of them inhomogeneous, were observed for the pore sizes considered and were found to be in good agreement with recent dielectric relaxation spectroscopy experiments for CCl(4) confined within multiwalled carbon nanotubes.
