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.

该奖项由重大研究仪器项目和化学研究仪器项目联合资助。纽约州立大学布罗克波特分校正在采购一台与条纹相机时间分辨荧光光谱仪耦合的飞秒激光器，以支持 Mark Heitz 教授及其同事 Paschalis Alexandridis、Johsua Blose 和 David McCamant 的研究。该仪器促进化学、生物化学和化学工程领域的研究。条纹相机与飞秒激光器结合使用，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速率记录光谱数据。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。该仪器增强了许多院系各级学生的教育、研究和教学工作，并为附近机构提供了使用便利。飞秒激光和条纹相机获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低共熔溶剂溶剂化背后的驱动力等领域。此外，其他研究包括更深入地了解控制变量，以改善基于纳米粒子的太阳能生产中的电子转移，并确定模型 DNA 和 RNA 寡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、药品、纳米技术和长期储存。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 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
