We present a computational study of the dynamic behavior of a Ziff-Gulari-Barshad model of CO oxidation with CO desorption on a catalytic surface. Our results provide further evidence that below a...
Decay of metastable phases in a model for the catalytic oxidation of CO (2004)
Machado, E., Buendia, G. M., Rikvold, P. A.
We study by kinetic Monte Carlo simulations the dynamic behavior of a Ziff-Gulari-Barshad model with CO desorption for the reaction CO + O $\to$ CO$_2$ on a catalytic surface. Finite-size scaling...
Surface scaling analysis of hydrogels: From multiaffine to self-affine scaling (2003)

We show that smoothing of multiaffine surfaces that are generated by simulating a crosslinked polymer gel by a frustrated, triangular network of springs of random equilibrium lengths [G.M....
Buendia, G. M., Mitchell, S. J., Rikvold, P. A.
We propose and study a simplified model for the surface and bulk structures of crosslinked polymer gels, into which voids are introduced through templating by surfactant micelles. Such systems were...
