Nonlinear Chemical Dynamics

布兰迪斯大学的欧文爱泼斯坦和阿纳托尔扎博廷斯基得到了理论和计算化学计划的支持，从事非线性化学动力学的研究，特别是反应扩散系统中模式形成的实验和计算研究。 光将被用来产生新类型的图案。 一个很少被研究的分岔（短波不稳定性）将在全球负反馈下进行研究，和强迫和非强迫混沌和多周期化学振荡器将进行研究。 本课程将探讨在非均匀介质中及含次磷酸盐的新化学体系中的图案形成。化学中的图案形成是现代宏观化学动力学的中心问题。 反应扩散系统是神经生物学、催化学和生态学中模式形成的最方便的模拟模型。 这些现象涉及全局反馈和/或化学波通过非均匀介质的传播。

Irving Epstein and Anatol Zhabotinsky of Brandeis University are supported by the Theoretical and Computational Chemistry Program to pursue research on nonlinear chemical dynamics, specifically experimental and computational investigations of pattern-formation in reaction-diffusion systems. Light will be used to produce new types of patterns. A rarely studied bifurcation (the short-wave instability) will be studied under global negative feedback, and forced and unforced chaotic and multiperiodic chemical oscillators will be investigated. Pattern formation in nonuniform media, and in a new hypophosphite-containing chemical system, will be explored.Pattern formation in chemistry is a central problem in modern macroscopic chemical kinetics. Reaction-diffusion systems constitute the most convenient analog models for pattern formation in neurobiology, catalysis, and ecology. These phenomena involve global feedback and/or the propagation of chemical waves through nonuniform media.
