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

该奖项由主要研究仪器项目和化学研究仪器项目共同支持。布洛克波特的纽约州立大学学院正在获取一台飞秒激光，该激光与条纹相机时间分辨荧光光谱仪耦合，以支持马克·海茨教授及其同事帕斯卡利斯·亚历山德里迪斯、乔苏亚·布洛泽和大卫·麦卡蒙特的研究。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，可以用来研究化学体系的超快动态过程。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速率记录光谱数据。光谱可以分解成亚皮秒的贡献，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。飞秒激光和条纹相机的获奖旨在加强所有级别的研究和教育，特别是在理解溶剂化能量学和动力学作为深度共晶溶剂中溶剂化背后的驱动力的领域。此外，其他研究包括加深对基于纳米颗粒的太阳能生产中改善电子转移的控制变量的理解，以及确定模型DNA和RNA齐聚物在离子液体和深度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溶液的生存能力。它还有助于确定控制黄原胶中链条相互作用的变量。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势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.
