MRI: track 1 acquisition of a multifunctional thermal analysis instrument for interdisciplinary research and research training in advanced nanomaterial development

The National Science Foundation (NSF) awarded a $224,834 Project Grant under its Integrative Activities program (CFDA 47.083) to Trustees of Union College in Schenectady, New York. The grant supports the acquisition of a multifunctional thermal analysis instrument, a TGA/FTIR/GC/MS system, to enhance interdisciplinary research and research training in advanced nanomaterial development. The instrument will enable the unambiguous characterization of the structural, mechanical, chemical, and physical properties of diverse nanomaterials, including plasmonic, semiconducting, metal oxide, and functionalized graphene oxide nanomaterials. The award also aims to provide research and educational opportunities for at least 50 undergraduate students annually. This project grant, effective from September 1, 2023 to August 31, 2026, aligns with NSF's mission to support research infrastructure that advances scientific knowledge and broadens participation in STEM fields.

Abstract

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.- subawards are not planned for this award.
