Waves of chemical or electrical activity, traveling through space, have been observed in
several contexts: chemical reaction mixtures in non-convecting liquid phase, cell …

Reaction–diffusion (RD) processes are common throughout nature, which uses them
routinely to build and control structures on length scales from molecular to macroscopic. At …

Chemical reactions with nonlinear kinetic behavior can give rise to a remarkable set of
spatiotemporal phenomena. These include periodic and chaotic changes in concentration …

In an earlier paper, we developed a general physical picture for the linear-marginal-stability
mechanism governing the dynamics of front propagation into linearly unstable states. The …

Figure 1 shows the front position versus time for one experiment. The initial burst of heat
causes rapid propagation, but the front reaches a steady velocityafter a few minutes. Visual …

Chemical reactions make cells work only if the participating chemicals are delivered to
desired locations in a timely and precise fashion. Most research to date has focused on …

The interdisciplinary field of nonlinear chemical dynamics has grown significantly in breadth
and depth over the past three decades. Its subject matter and applications encompass all …

Nonequilibrium spatially distributed chemically reacting systems are usually described in
terms of reaction-diffusion equations. In this article, a hierarchy of discrete models is studied …

We consider the effects of convection on chemical waves in which density gradients result
from the exothermicity as well as from the isothermal volumechange of the reaction. If the …

Traveling fronts of polymerization have been observed in unstirred solutions of methacrylic
acid and benzoyl peroxide. Three types of convective instabilities have been observed.(1) …
