CHEM 515: Chemical Kinetics and Dynamics

چکیده
Spontaneous antispiral wave formation was observed during the simulation of typical reaction-diffusion systems using differential equations models. The equations for the FitzHugh-Nagumo (FHN), complex Ginzburg-Landau (CGL) and the two-variable Oregonator models were integrated using Runge-Kutta methods. It was found that antispiral waves can occur only near the Hopf bifurcation, i.e. the point at which the system starts to oscillate. The specific conditions required for antispiral wave formation were established through theoretical analysis and numerical simulations. The results explain a number of phenomena observed in oscillatory reactions such as the Belousov-Zhabotinsky (BZ) reaction.

متن کاملEsterification Reaction Kinetics Using Ion Exchange Resin Catalyst by Pseudo-Homogenous and Eley-Ridel Models
This work deals with kinetics and chemical equilibrium studies of esterification reaction of ethanol with acetic acid. The esterification reaction was catalyzed by an acidic ion exchange resin (Amberlyst-15) using a batch stirred tank reactor. The pseudo-homogenous and Eley-Rideal models were successfully fitted with experimental data. At first, Eley-Rideal model was examined for heterogeneous...

متن کاملStochastic chemical kinetics and the quasi-steady-state assumption: Application to the Gillespie algorithm
Biochemical dynamics are often determined by series of single molecule events such as gene expression and reactions involving protein concentrations at nanomolar concentrations. Molecular fluctuations, consequently, may be of biological significance. For example, heterogeneity in clonal populations is believed to arise from molecular fluctuations in gene expression. A realistic description, the...
متن کاملComparison of the kinetics of different Markov models for ligand binding under varying conditions.
We recently derived a Markov model for macromolecular ligand binding dynamics from few physical assumptions and showed that its stationary distribution is the grand canonical ensemble [J. W. R. Martini, M. Habeck, and M. Schlather, J. Math. Chem. 52, 665 (2014)]. The transition probabilities of the proposed Markov process define a particular Glauber dynamics and have some similarity to the Metr...
