MRI: Acquisition of Mass Spectrometer-Coupled Thermogravimetric Analyzer System

该奖项由重大研究仪器(MRI)和化学仪器(CRIF)计划资助。纽约州立大学奥尔巴尼分校的Jeremy Feldblyum教授及其同事John Welch、Rabi Musah、Evgeny Dikarev和Marina Petrukhina获得了一套配备质谱仪(TGA-MS)的热重分析系统。该仪器测量样品受热时的重量。随着蒸气的演化，样品由质谱仪分析，以确定排放的蒸气的质量和化学成分。这些数据提供了有关样品本身的身份及其成分(如果是混合物)的信息。蒸气可以是分解产物，提供有关样品热稳定性的信息。TGA-MS是分析材料的有力工具。这项研究可能会影响许多领域，包括有机化学和无机化学以及聚合物化学。一个例子涉及合成可用于分离碳氢燃料中高价值有机化合物的材料，这些化合物很难通过蒸馏分离。在另一个项目中，储能材料正在进行测试。用于光刻的新型聚合物的热分解也在研究中。地方研究机构，包括大学和学院、商业公司和政府机构对仪器的使用(例如，(纽约州犯罪实验室)受到鼓励。该仪器为本科生和研究生提供研究和实验室教学方面的培训机会。这款热重分析仪的收购加强了纽约州立大学奥尔巴尼分校及周边机构的本科生和研究生的研究和教育。用于制备能源相关材料的异金属分子前驱体正在研究中。金属有机骨架(MOF)正被测试用于分离高价值的有机化合物。用于氢捕获的存储材料正在合成和测试中。在热加热研究中，对用于光刻的聚合物的分解机理进行了跟踪。对RNA链/纤维的水解吸研究进行了评估，以了解热稳定性和相对吸附热。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 funded by the Major Research Instrumentation (MRI) and Chemical Instrumentation (CRIF) programs. Professor Jeremy Feldblyum from SUNY at Albany and colleagues John Welch, Rabi Musah, Evgeny Dikarev and Marina Petrukhina have acquired a thermal gravimetric analysis system equipped with a mass spectrometer (TGA-MS). This instrument measures the weight of a sample as it is heated. As vapors evolve, the samples are analyzed by a mass spectrometer to determine the mass and chemical composition of the vapors emitted. This data provides information on the identity of the sample itself and its composition (if a mixture). The vapors may be decomposition products providing information on the thermal stability of the sample. TGA-MS is a powerful tool in analyzing materials. The research may impact many areas, including organic and inorganic chemistry and polymer chemistry. One example involves the synthesis of materials which can be used to separate high-value organic compounds in hydrocarbon fuels which are difficult to separate by distillation. In another project, energy storage materials are being tested. The thermal decomposition of novel polymers used in photolithography is also being investigated. Instrumentation usage by local research institutions, including universities and colleges, commercial companies and government institutions (eg. the NY State Crime Laboratory) is encouraged. The instrument provides training opportunities for students at both the undergraduate and graduate levels in research and laboratory instruction. The acquisition of this thermogravimetric analyzer enhances the research and education of undergraduate and graduate students at SUNY at Albany and surrounding institutions. Heterometallic molecular precursors for the preparation of energy-related materials are under investigation. Metal-organic frameworks (MOFs) are being tested for separating high-value organic compounds. Storage materials such as for hydrogen capture are being synthesized and tested. The decomposition mechanism of polymers useful in photolithography is followed in thermal heating studies. Water desorption studies from RNA strands/fibers is assessed to understand thermal robustness and relative heats of adsorption.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.
