Proposal Number: CTS-0217746Institution: U ChicagoPI Name: B. 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.

提案编号：CTS-0217746机构：U Chicago PI姓名： B。LinTitle： 胶体悬浮体在水中的扩散、相互作用和结构性质 一维通道摘要本项目研究的是悬浮在狭窄通道内液体中的胶体颗粒的动力学行为。 这种布置提供了一个实验装置来研究一维孔中的颗粒输运特性。 结果表明，附近的墙壁的存在下，影响阻力的翻译粒子之间的相互作用产生非菲克运输内的孔隙。 实验的目的是调查一维扩散的特点，难以在理论上分析，在这个复杂的几何形状和实际应用。 我们的目标是获得新的信息，运输在有限的几何形状没有预期从现有的理论。 拟议的项目将阐明颗粒的大小（相对于通道尺寸）的传输被描述为一个一维扩散模型。
