MRI: Acquisition of a Femtosecond Laser/Streak Camera Fluorescence Spectrometer

该奖项由主要研究仪器和化学研究仪器计划共同支持。纽约州立大学布罗克波特分校正在购买一种飞秒激光器，该激光器与条纹相机时间分辨荧光光谱仪耦合，以支持Mark Heitz教授及其同事Paschalis Alexandis，Johsua Blose和大卫McCamant的研究。该仪器有助于化学、生物化学和化学工程领域的研究。当与飞秒激光器结合时，条纹相机可用于研究化学系统的超快动力学过程。条纹相机检测器通过使用多个通道以非常高的帧速率记录光谱数据来工作。光谱可以分解为亚皮秒贡献，以了解激发态衰变动力学和分子动力学作为分子相互作用的函数。这一仪器不仅为许多部门的各级学生提供了教育、研究和教学的机会，也为附近的机构提供了使用便利。飞秒激光和条纹相机奖旨在加强各级研究和教育，特别是在理解溶剂化能量学和动力学作为深共熔溶剂中溶剂化背后的驱动力等领域。此外，其他研究包括建立更深入的了解控制变量，以改善基于纳米颗粒的太阳能生产中的电子转移，并确定模型DNA和RNA低聚物在离子液体和低共熔溶剂中的结构稳定性，以提高提取，纯化，制药，纳米技术和长期储存的解决方案的可行性。该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的知识价值和更广泛的影响审查标准进行评估来支持。

This award is jointly supported by the Major Research Instrumentation and the Chemistry Research Instrumentation Programs. SUNY College at Brockport is acquiring a femtosecond laser that is coupled to a streak camera time-resolved fluorescence spectrometer to support the research of Professor Mark Heitz and colleagues Paschalis Alexandridis, Johsua Blose, and David McCamant. This instrument facilitates research in the areas of chemistry, biochemistry, and chemical engineering. A streak camera, when combined with a femtosecond laser, can be used to study ultrafast dynamic processes of chemical systems. The streak camera detector works by recording spectral data using multiple channels at very high frame rates. Spectra can be resolved into sub-picosecond contributions to understand excited-state decay kinetics and molecular dynamics as a function of molecular interactions. This instrument enhances the educational, research, and teaching efforts of students at all levels in many departments as well as provides accessibility for use at nearby institutions.The award for the femtosecond laser and streak camera is aimed at enhancing research and education at all levels, especially in areas such as the understanding of solvation energetics and dynamics as the driving force behind solvation in deep eutectic solvents. In addition, other investigations include building a deeper understanding of control variable for improved electron transfer in nanoparticle-based solar energy production and determining structural stability of model DNA and RNA oligomers in ionic liquids and deep eutectic solvents to improve solution viability for extraction, purification, pharmaceuticals, nanotechnology, and long-term storage. It also aids in the determination of variables that govern chain interactions in xanthan gum.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
