[Autocatalytic enzyme reactions].

Molekuliarnaia biologiia, 1979
Kinetic aspects of enzymatic reactions proceeding in the autocatalytic mode are considered. Kinetic analysis of a mechanism with proenzyme-enzyme interaction and of mechanism in which activation involves an interaction with the product of enzymatic reaction is presented. It is shown that these mechanisms are distinguished by the dependences of kinetics

Quasistationary distributions for autocatalytic reactions

Journal of Statistical Physics, 1987
We provide simple conditions for the existence of quasistationary distributions that can be used to describe the long-term behaviour ofopen autocatalytic reaction systems. We illustrate with reference to a particular example that the quasistationary distribution is close to the usual stationary diffusion approximation.

Critical behavior of an autocatalytic reaction model

Physical Review A, 1990
Irreversible many-particle dynamical systems are relevant to a variety of phenomena in physics, chemistry, and biology. We present a study of an irreversible kinetic reaction model for a one-component autocatalytic reaction A+A\ensuremath{\rightarrow}${\mathit{A}}_{2}$.

Marginal states in a cubic autocatalytic reaction

The Journal of Chemical Physics, 2011
Marginal steady state belongs to a special class of states in nonlinear dynamics. To realize this state we consider a cubic autocatalytic reaction A + 2B → 3B in a continuous-stirred-tank-reactor, where the flow rate of the reactant A can be controlled to manipulate the dynamical behavior of the open system.

Some properties of autocatalytic reactions

Chemical Engineering Science, 1968
Abstract A chain of autocatalytic reactions, first proposed by Lotka in 1910, exhibit some unusual behaviors. Under proper conditions the concentrations of various species oscillate about steady state values. Conditions that lead to such oscillations are discussed. When these oscillating concentrations are plotted against each other, a closed ring or

Autocatalytic reactions of phase distributed active particles

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2002
We investigate the effect of asynchronism of autocatalytic reactions taking place in open hydrodynamical flows, by assigning a phase to each particle in the system to differentiate the timing of the reaction, while the reaction rate (periodicity) is kept unchanged.

Thermal explosion of autocatalytic reaction

Journal of Loss Prevention in the Process Industries, 2003
Abstract Analytical and numerical solutions are used to determine the critical conditions for thermal explosion of autocatalytic reaction. The solutions covers both the reaction governed by the Arrhenius kinetics equation and the Frank-Kamenetskii approximation for that equation. The definition of criticality as the point at which d 2 θ / dβ 2 =0,

Statistical Fluctuations in Autocatalytic Reactions

The Journal of Chemical Physics, 1940
The differential equations describing the statistical fluctuations of a simple autocatalytic reaction mechanism are set up and solved completely. The fluctuations are found to approach a constant limiting value when the amount of reaction product is large compared to the amount which initiates the reaction.

SURFACE EXPLOSION IN AUTOCATALYTIC MONOMER-MONOMER REACTIONS

Fractals, 1996
A lattice model of the A-B type has been introduced recently to describe temporal oscillations and pattern formation for the NO-CO reaction catalyzed by a Pt surface. Under certain experimental conditions one observes the rapid reactional removal of an adsorbed layer upon nucleation — a direct consequence of the autocatalytic nature of the reaction ...
