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项目联合支持。位于布罗克波特的纽约州立大学正在获得一种飞秒激光器，该激光器与条纹相机时间分辨荧光光谱仪相结合，以支持马克·海茨教授及其同事帕斯查里斯·亚历山大里迪斯、约翰·布洛泽和大卫·麦卡曼特的研究。该仪器促进了化学、生物化学和化学工程领域的研究。条纹相机与飞秒激光相结合，可用于研究化学系统的超快动态过程。条纹相机探测器的工作原理是使用多个通道以非常高的帧率记录光谱数据。光谱可以分解为亚皮秒贡献，以理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。该仪器提高了许多院系各级学生的教育、研究和教学努力，并为附近的机构提供了可访问性。飞秒激光和条纹相机的奖项旨在加强各级的研究和教育，特别是在诸如理解溶剂化能量学和动力学作为深共晶溶剂溶剂化背后的驱动力等领域。此外，其他研究还包括深入了解纳米粒子太阳能生产中改善电子转移的控制变量，以及确定离子液体和深度共晶溶剂中模型DNA和RNA低聚物的结构稳定性，以提高溶液在提取、纯化、制药、纳米技术和长期储存方面的可行性。它还有助于确定黄原胶中控制链相互作用的变量。该奖项反映了美国国家科学基金会的法定使命，并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，被认为值得支持。

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.
