Lattice-gas modeling of enantioselective adsorption by template chiral substrates

Romá, F.; Stacchiola, D.; Tysoe, W.T.; Zgrablich, G. - In: Physica A: Statistical Mechanics and its Applications 338 (2004) 3, pp. 493-510

The general behavior of enantioselective adsorption by templated chiral substrates is studied in the framework of … lattice-gas and random sequential adsorption theories. The template is assumed to be formed by randomly preadsorbing a chiral … species A on a square lattice of sites. A second chiral probe species, B, thus performs a random sequential adsorption process …
