项目摘要

This award is supported by the Major Research Instrumentation (MRI) and the Chemistry Research Instrumentation Programs. Professor Piotr Piotrowiak from Rutgers University Newark and colleagues Edward Castner, Elena Galoppini, Jenny Lockhard and Kevin Belfield (New Jersey Institute of Technology) are acquiring a pump-probe transient absorption and fluorescence upconversion spectrometer system. This is a laser based system which enables the study of a wide range of laser phenomena that address significant challenges of social, environmental and economic importance. Research topics focus on solar energy research, renewable energy and green chemistry, photovoltaic materials, and biomarkers linked to human health. The instrumentation strengthens research and training at three institutions: Rutgers-Newark, Rutgers-New Brunswick and the New Jersey Institute of Technology. This pump-probe transient absorption and fluorescence upconversion spectrometer system enhances research and education at all levels. It serves researcher who are testing the interplay between electron transfer and vibrational cooling in extended donor-acceptor arrays as well as those seeking understanding of ionic liquids. Research probing the fundamental relationship between molecular structure and nonlinear optical properties of chromophores also utilize this instrument. The spectrometer system is used to look for surface modification strategies and synthetic tools to understand interfacial charge separation and electron transfer dynamics. Researchers carry out mechanistic studies on photocatalytic properties of hybrid materials to unify nanoscience, coordination chemistry and catalysis. The spectrometer is important in seeking to unravel terrestrial surface photogeochemistry in the Archaen period.

该奖项得到了主要的研究工具（MRI）和化学研究工具计划的支持。来自罗格斯大学纽瓦克大学的Piotr Piotrowiak教授和同事爱德华·卡斯特纳，埃琳娜·加洛普皮尼，珍妮·洛克哈德和凯文·贝尔菲尔德（新泽西技术学院）正在获取泵送的临时吸收和荧光上的速度吸收和荧光上升频率分频器系统。这是一个基于激光的系统，可以研究各种激光现象，以应对社会，环境和经济重要性的重大挑战。研究主题着重于太阳能研究，可再生能源和绿色化学，光伏材料以及与人类健康相关的生物标志物。该仪器在三个机构中加强了研究和培训：Rutgers-Newark，Rutgers-New Brunswick和新泽西理工学院。这种泵探针瞬态吸收和荧光上调光谱仪系统可以在各个级别上增强研究和教育。它为研究人员提供服务，他们正在测试扩展供体阵列中电子传递和振动冷却之间的相互作用，以及寻求对离子液体了解的人。研究探测分子结构与发色团非线性光学特性之间的基本关系的研究也利用了该仪器。光谱仪系统用于寻找表面修饰策略和合成工具，以了解界面电荷分离和电子传输动力学。研究人员对杂交材料的光催化特性进行机械研究，以统一纳米科学，协调化学和催化。光谱仪对于试图在古时揭开陆地表面光地球化学很重要。
