Effects of external global noise on the catalytic CO oxidation on Pt(110)
P. S. Bodega, S. Alonso, H. H. Rotermund
Oxidation reaction of CO on a single platinum crystal is a reaction-diffusion system that may exhibit bistable, excitable, and oscillatory behavior. We studied the effect of a stoc…
Enhancement of surface activity in CO oxidation on Pt(110) through spatiotemporal laser actuation
L. Qiao, X. Li, I. G. Kevrekidis +2
We explore the effect of spatiotemporally varying substrate temperature profiles on the dynamics and resulting reaction rate enhancement for the catalytic oxidation of CO on Pt(110…
Self-Replication of Mesa Patterns in Reaction-Diffusion Systems
T. Kolokolnikov, M. J. Ward, J. Wei
Certain two-component reaction-diffusion systems on a finite interval are known to possess mesa (box-like) steadystate patterns in the singularly perturbed limit of small diffusivi…
Spot deformation and replication in the two-dimensional Belousov-Zhabotinski reaction in water-in-oil microemulsion
Theodore Kolokolnikov, Mustapha Tlidi
In the limit of large diffusivity ratio, spot-like solutions in the two-dimensional Belousov-Zhabotinski reaction in water-in-oil microemulsion are studied. It is shown analyticall…
