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.

该奖项由主要研究仪器（MRI）和化学研究仪器项目支持。纽瓦克罗格斯大学的Piotr Piotrowiak教授和他的同事Edward Castner， Elena Galoppini， Jenny Lockhard和Kevin Belfield（新泽西理工学院）正在获得一种泵浦探针瞬态吸收和荧光上转换光谱仪系统。这是一个基于激光的系统，可以研究广泛的激光现象，解决社会，环境和经济重要性的重大挑战。研究主题集中在太阳能研究、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。该仪器加强了罗格斯-纽瓦克大学、罗格斯-新不伦瑞克大学和新泽西理工学院这三所大学的研究和培训。这种泵-探针瞬态吸收荧光上转换光谱仪系统提高了各级的研究和教育。它服务于研究人员，他们正在测试电子转移和振动冷却之间的相互作用，在扩展的供体-受体阵列以及那些寻求离子液体的理解。研究分子结构与发色团非线性光学性质之间的基本关系也利用该仪器。该光谱仪系统用于寻找表面改性策略和合成工具，以了解界面电荷分离和电子转移动力学。研究人员对杂化材料的光催化性能进行机理研究，以统一纳米科学、配位化学和催化。光谱仪在寻求揭示太古宙时期的地球表面光地球化学是重要的。
