With this award from the Major Research Instrumentation Program and support from the Chemistry Research Instrumentation Program, Professor Jennifer Ogilvie from the University of Michigan and colleagues Stephen Forrest, Kevin Kubarych, Theodore Norris and Vanessa Sih will develop a multispectral multidimensional non-linear (MMDS) spectrometer to enable studies of dynamical processes in atomic, molecular, and material systems spanning femtoseconds to seconds, from the ultraviolet (UV) to the infrared (IR) regimes. This will allow insight into DNA photodamage and repair mechanisms and metalloenzyme function. The ability to mix and match infrared, visible and ultraviolet wavelengths will be a novel and potentially very powerful technique. The investigators will create modules that will serve for outreach activities to K-12 students. Importantly, participation of students and postdoctoral associates in this project will serve to educate a new generation of instrumentalists.The award is aimed at enhancing research and education at all levels, especially in areas such as the study of complex condensed phase systems. The instrument will also be used to probe the dynamics of the building blocks of biological matter: amino and nucleic acids, to gain insight into DNA photodamage and repair mechanisms and metalloenzyme function and will provide a tool for studying the physics of nanostructures. It is also noted that the instrument would address key questions relevant to improving the efficiency of organic photovoltaic devices.

有了来自主要研究仪器计划的这一奖项和化学研究仪器计划的支持，密歇根大学的Jennifer Ogilvie教授及其同事Stephen Forrest，Kevin Kubarych，西奥多诺里斯和Vanessa Sih将开发一种多光谱多维非线性（MMDS）光谱仪，以研究原子，分子和材料系统中的动态过程，时间跨度为飞秒到秒，从紫外（UV）到红外（IR）区域。这将允许深入了解DNA光损伤和修复机制以及金属酶功能。混合和匹配红外、可见光和紫外波长的能力将是一种新颖的、潜在的非常强大的技术。调查人员将创建模块，用于K-12学生的外联活动。重要的是，学生和博士后参与该项目将有助于培养新一代的仪器演奏家。该奖项旨在加强各级研究和教育，特别是在复杂凝聚相系统研究等领域。该仪器还将用于探测生物物质的组成部分：氨基和核酸的动力学，以深入了解DNA光损伤和修复机制以及金属酶的功能，并将为研究纳米结构的物理学提供工具。还注意到，该文书将解决与提高有机光伏器件效率有关的关键问题。
