标题： Growth kinetics of circular liquid domains on vesicles by diffusion-controlled coalescence

摘要： 受对多组分膜的最近实验的启发，理论研究了囊泡上畴的生长动力学。 已知当将膜视为无限二维（2D）系统时，不能通过取聚并速率的长时间极限来获得稳态聚并速率。 通过明确考虑球形囊泡形状，获得了稳态聚并速率。 使用在小畴尺寸极限下得到的二维扩散系数表达式，在圆形容畴始终保持的情况下，得到了畴生长动力学的解析表达式。 对于大畴，通过研究聚并速率的尺寸依赖性，利用任意尺寸畴的扩散系数表达式讨论了生长动力学。 显示英文摘要

摘要： Motivated by recent experiments on multi-component membranes, the growth kinetics of domains on vesicles is theoretically studied. It is known that the steady-state rate of coalescence cannot be obtained by taking the long-time limit of the coalescence rate when the membrane is regarded as an infinite two-dimensional (2D) system. The steady-state rate of coalescence is obtained by explicitly taking into account the spherical vesicle shape. Using the expression of the 2D diffusion coefficient obtained in the limit of small domain size, an analytical expression for the domain growth kinetics is obtained when the circular shape is always maintained. For large domains, the growth kinetics is discussed by investigating the size dependence of the coalescence rate using the expression for the diffusion coefficient of arbitrary domain size.
