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.

该提案要求购买一个宽激发/检测范围，在fs时域，使用Ti -蓝宝石为基础的吸收系统（反射/上转换荧光）系统。该仪器的激发范围为240-2600 nm，检测范围为360-1700 nm，时间窗为150 fs至10 ns。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。该组合仪器为交钥匙式机器，操作简单，维护方便。它被认为是当代前沿科学的关键仪器。该仪器将主要服务于大量的PI（超过15列出），但不仅仅是在生物工程系。大量感兴趣的各方将鼓励跨学科的互动。此次收购将大大扩展UC-Riverside目前可用的能力和资源，用于正在进行的研究项目。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扩大合作的潜力。它还将扩大对本科生和研究生以及高中生的机会，特别是来自地方的少数民族学生。
