建议编号：CTS-0217746机构：U芝加哥国际名称：B.林书豪题目：胶体悬浮液在一维通道中的扩散、相互作用和结构特性摘要拟议的项目是关于受限于狭窄通道内的液体中胶体颗粒的动力学行为。这种布置为研究一维气孔中的颗粒输运特性提供了实验装置。结果表明，近壁的存在影响了平移颗粒上的阻力，其中颗粒之间的相互作用在气孔内产生了非费克输运。这些实验旨在研究一维扩散的特性，在这种复杂的几何结构和实际应用中，很难从理论上分析这一特性。我们的目标是获得现有理论没有预料到的关于受限几何中传输的新信息。拟议的项目将阐明将由一维扩散模型描述的用于传输的颗粒的大小(相对于通道尺寸)。

LinTitle: Diffusion, interactions and structural properties of colloidal suspensions in one-dimensional channelsABSTRACTThe proposed project is on the dynamical behavior of colloidal particles suspended in liquid confined within a narrow channel. This arrangement provides an experimental setup to investigate the particle transport characteristics in one-dimensional pores. It is shown that the presence of nearby walls affects the drag on a translating particle where interactions among particles produce non-Fickian transport within a pore. The experiments are designed to investigate the characteristics of one-dimensional diffusion, difficult to analyze theoretically in this complicated geometry and in realistic applications. The goal is to obtain new information about transport in confined geometry not anticipated from existing theories. The proposed project will shed light on the size of the particles (relative to the channel dimensions) for transport to be described by a one-dimensional diffusion model.
