This award is jointly supported by the Major Research Instrumentation and the Chemistry Research Instrumentation programs. Union College is acquiring a thermogravimetric analyzer integrated with a Fourier Transform infrared spectrometer and a gas chromatograph/mass spectrometer (TGA/FTIR/GC/MS) system to support the research of Ellen Robertson, Ann Anderson, Mary Carroll, Yijing Stehle, and Christopher Whitehead and other colleagues at the institution. In general, a thermogravimetric analyzer (TGA) is a scientific instrument that aids the characterization of the structural, mechanical, chemical, and physical properties of materials as a function of temperature. However, having only information about the material weight loss as a function of temperature is not sufficient for answering the specific research questions associated with each material. Instead, a thorough characterization of the chemical species that are released during material heating is often desired. A TGA/FTIR/GC/MS system allows for the unambiguous identification of material thermal degradation products through the assignment of both vibrational modes (Fourier Transform Infrared Spectroscopy – FTIR) and molecular weight analysis (Mass Spectroscopy – MS). The instrument impacts many areas, such as chemistry, mechanical engineering, materials science, and nanotechnology. Furthermore, the new instrumen provides research and educational opportunities for a diverse group of at least 50 undergraduate students annually, both inside and outside of the classroom.The award is aimed at enhancing research and education at all levels. Research enabled by the instrument is focused on characterizing the structural, mechanical, chemical, and physical properties of diverse classes of modern nanomaterials, including plasmonic nanomaterials for detecting pollutants, semiconducting quantum dots for heavy metal sensing, metal oxide nanocrystals and aerogels for catalysis, and functionalized graphene oxide membranes for water filtration and purification. The instrument allows for the unambiguous identification of nanomaterial thermal degradation products through the assignment of both vibrational modes and molecular weight signatures.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.

该奖项由主要的研究工具和化学研究工具计划共同支持。联合学院正在收购与傅立叶变换红外光谱仪和气相色谱/质谱仪（TGA/FTIR/GC/MS）系统集成的热重分析仪，以支持Ellen Robertson，Ann Annerson，Mary Carroll，Mary Carroll，Yijing Stehle，Yijing Stehle和Christopher Whitehead和其他Insteration Instistration的研究。通常，热重分析仪（TGA）是一种科学仪器，可帮助表征材料的结构，机械，化学和物理特性，这是温度的函数。但是，只有有关体重减轻作为温度函数的信息不足以回答与每种材料相关的特定研究问题。取而代之的是，通常需要对材料加热期间释放的化学物种进行彻底表征。 TGA/FTIR/GC/MS系统可以通过分配振动模式（傅立叶变换红外光谱 - FTIR）和分子量分析（质谱 - 质谱 - MS）来明确鉴定材料热降解产物。该仪器会影响许多领域，例如化学，机械工程，材料科学和纳米技术。此外，新的乐器人每年在课堂内外，每年至少有50名本科生的潜水员群体提供研究和教育机会。该奖项旨在增强各个级别的研究和教育。该仪器启用的研究重点是表征现代纳米材料的潜水类别类别的结构，机械，化学和物理特性，包括用于检测污染物的血浆式纳米材料，用于重金属感应，金属氧化物纳米晶体的半导体量子点，用于催化元素和功能化的石墨素化元素和纯含量的金属氧化物纳米晶体和气管。该仪器允许通过分配振动模式和分子量特征来明确鉴定纳米材料的热降解产物。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子优点和更广泛影响的评估标准通过评估来评估的。
