Nanostructures, Polymers and Dense Fluids: Ultrafast Dynamics

该项目将专注于在控制尺寸、密度和距离的条件下解决主要的皮秒和飞秒动力学，并了解各种材料系统向凝聚相极限过渡的结构动力学相关性和力。超快激光光谱学将用于探测凝聚态纳米结构的实时分子动力学，研究高压下聚合物和材料的光物理和光化学动力学，以及使用新颖的非线性激光技术来检查和控制非均匀系统中的选择过程。纳米材料和工艺的潜力及其在各种纳米器件中的新用途刚刚开始在通信、生物技术和各种微机电系统等技术中得到实现。在科学和工程领域接受培训的学生将探索介于孤立原子/分子和块状材料之间的材料的物理、化学和生物特性，其中现象长度尺度与结构的大小相当，他们将成为未来与推动新兴全球经济最相关的科学家和工程师之一。

This project will focus on resolving primary picosecond and femtosecond dynamics under conditions of controlled size, density and distance, and to learn about structure-dynamics correlations and forces governing the transition to the condensed phase limit for various materials systems. Ultrafast laser spectroscopy will be used to probe real-time molecular dynamics of nanostructures in the condensed phase, studies of the photophysical and photochemical dynamics of polymers and materials under high pressure, and the use of novel and non-linear laser techniques will be used to examine and control selective processes in inhomogeneous systems.The potential for nanoscale materials and processes and their novel uses in various nanoscale device are just beginning to be realized for technologies such as communications, biotechnology, and various microelectromechanical systems. Students trained in science and engineering areas that explore the physical, chemical, and biological properties of materials intermediate in size between isolated atoms/molecules and bulk materials, where phenomena length scales become comparable to the size of the structure, will be among those future scientists and engineers most relevant to advancing the emerging global economy.
