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.

该奖项由主要研究仪器（MRI）和化学仪器（CRIF）项目资助。来自纽约州立大学奥尔巴尼分校的Jeremy Feldblyum教授和他的同事John Welch， Rabi Musah， Evgeny Dikarev和Marina Petrukhina获得了一个配备质谱仪（TGA-MS）的热重分析系统。这个仪器在样品被加热时测量其重量。随着蒸汽的演变，样品被质谱仪分析，以确定释放的蒸汽的质量和化学成分。该数据提供了样品本身及其成分（如果是混合物）的信息。蒸汽可能是分解产物，提供样品热稳定性的信息。TGA-MS是一种功能强大的材料分析工具。该研究可能会影响许多领域，包括有机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难以通过蒸馏分离的高价值有机化合物的材料。在另一个项目中，储能材料正在测试中。用于光刻的新型聚合物的热分解也正在研究中。本地研究机构（包括大学和学院、商业公司和政府机构）使用仪器的情况。（纽约州犯罪实验室）。该仪器为本科生和研究生在研究和实验室教学方面提供了培训机会。这台热重分析仪的收购增强了纽约州立大学奥尔巴尼分校和周边机构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体正在研究中。金属-有机框架（MOFs）用于分离高价值有机化合物的试验正在进行中。诸如氢捕获的储存材料正在合成和测试中。在热加热研究中，遵循了光刻用聚合物的分解机理。评估RNA链/纤维的水解吸研究，以了解热稳健性和相对吸附热。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。
