MRI: Acquisition of an Ultrafast Spectroscopy System for Biological and Engineering Research

0923408VullevThis proposal requires purchase a broad-excitation/detection ranges，in the fs time-domain，using a Ti -Sapphaire based system for absorption（reflectance/ up-conversion fluorescence）system.该仪器将覆盖240-2600 nm的激发范围，360-1700 nm的检测范围和150 fs至10 ns的时间窗口。组装的仪器将主要用于研究各种系统中的电荷转移过程，从太阳能转换方案中的电荷分离和重组到生物相关的氧化还原系统。组装后的仪器为交钥匙型，操作简单，维护方便。它被认为是当代前沿科学的关键工具。该工具将服务于大多数PI（列出的PI超过15个），但不仅仅是在部门内。生物工程学大量的相关方将鼓励跨学科的互动。此次收购将显著扩大加州大学河滨分校目前可用的能力和资源，以研究正在进行的项目。这将扩大UC-R研究人员与该地区其他机构和公司研究人员之间的合作潜力。它还将扩大本科生、研究生和高中生，特别是当地少数民族学生的机会。

0923408VullevThis proposal requests the purchase of a broad-excitation/detection ranges, in the fs time-domain, using a Ti - Sapphaire-based system for absorption (reflectance/ up-conversion fluorescence) system. The instrument will cover the excitation range of 240-2600 nm, detection in the range of 360-1700 nm and a time window of 150 fs to 10 ns. The assembled instrument will be utilized primarily to study charge-transfer processes in a variety of systems from charge separation and recombination in solar energy conversion schemes to biologically relevant redox systems. The assembled instrument is a turnkey type machine, simple to operate and easy to maintain. It is considered a key instrument in contemporary frontier science. The instrument will serve a large number of PI's (over 15 are listed) mostly, but not solely in the Dept. of Bioengineering. The large number of interested parties will encourage inter-disciplinary interactions. This acquisition will significantly expand the capabilities and resources that are currently available at UC-Riverside to research projects that are in progress. This will expand the potential for expanding collaboration among the investigators from UC-R and those from other institutions and companies in the region. It will also expand the opportunities that will be available to undergraduate and graduate as well as high school students, and in particular minority students from local area.
