RUI: Time-Resolved Photon Correlation Spectroscopy: A New Approach in the Study of Particle Dynamics

该RUI计划专注于开发和研究一种新的时间分辨光子关联光谱技术，该技术将允许在使用传统光子关联方法成功探测到的浓度范围之外的系统中研究粒子动力学。更好地了解这类系统将是许多领域基础知识的重大进步，也是对重大技术应用的非常现实的期望。这项研究中将研究的基本系统包括胶体颗粒在受限几何形状中的行为，铁磁性颗粒在外部磁场的影响下形成一维准晶体，以及胶体颗粒在结晶过程中动力学行为的变化。更广泛地说，这项工作将加强古斯塔夫斯·阿道夫学院现有的研究计划，并将为参与者、学院和更广泛的科学界带来重大好处。

This RUI program focuses on the development and study of a new time resolved photon correlation spectroscopy technique that will permit the investigation of particle dynamics in systems that are beyond the concentration range that can be successfully probed using traditional photon correlation methods. A better understanding of such systems will represent a significant advancement of basic knowledge in many fields as well as offering the very realistic expectation of significant technological application. The systems of fundamental importance that will be investigated in the research include the behavior of colloidal particles in confined geometry, ferro-magnetic particles forming a one-dimensional quasi-crystal under the influence of an external magnetic field, and the change in the dynamical behavior of colloidal particles during crystallization. In broader terms, this work will enhance the existing research program at Gustavus Adolphus College and will produce significant benefits for the participants, the College, and the broader scientific community.
