自组装和相变中的动力学俘获机制

Mechanisms of kinetic trapping in self-assembly and phase transformation

Michael F. Hagan, Oren M. Elrad, Robert L. Jack

摘要:

在自组装过程中,动力学捕获效应往往阻碍了有序稳定态的形成。在一个模型中的病毒衣壳组装和晶格气体的相变,我们展示了如何模拟在自组装稳态可以用来识别两种不同的机制的动力学捕获。我们认为,这些机制之一,可以充分捕获的动力学速率方程,而另一个涉及依赖于集群大小作为反应坐标的理论的故障。我们将讨论如何这些意见可能是有用的设计和优化自组装反应。

英文摘要:

In self-assembly processes, kinetic trapping effects often hinder the formation of thermodynamically stable ordered states. In a model of viral capsid assembly and in the phase transformation of a lattice gas, we show how simulations in a self-assembling steady state can be used to identify two distinct mechanisms of kinetic trapping. We argue that one of these mechanisms can be adequately captured by kinetic rate equations, while the other involves a breakdown of theories that rely on cluster size as a reaction coordinate. We discuss how these observations might be useful in designing and optimising self-assembly reactions.
