This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).With this award from the Major Research and Instrumentation (MRI) program, Professor David S. Karpovich, Jason J. Pagano, Christopher H. Schilling, Tami L. Sivy and Ron R. Williams from Saginaw Valley State University will acquire a Raman spectrometer, a thermal gravimetric analysis instrument (TGA), and a differential scanning calorimeter (DSC). The instruments will be used to study the production of novel biodegradable plastics from regional agricultural and bio-fuel waste products and to analyze tubular precipitation structures formed in geological and biological systems. Raman spectroscopy, thermal gravimetric analysis, and differential scanning calorimetry will be used to correlate the spectral and thermal properties associated with specific intermolecular interactions and transitions in materials, with their physical/mechanical properties. The Raman spectrum provides information on the chemical composition and structure of materials. Thermo-gravimetric analysis (TGA) measures weight changes in a material as a function of temperature providing information on the decomposition or evaporation from a sample as it is heated. Differential scanning calorimetry (DSC) measures the heat required to raise the temperature of a material and helps to identify physical changes, such as phase transitions. The combined use of these instruments will allow for the improvement of bio-plastics, optimizing their tensile strength and reducing brittleness.

该奖项由2009年《美国复苏和再投资法案》(Public Law 111-5)资助。在重大研究和仪器(MRI)项目的资助下，萨吉诺山谷州立大学的David S.Karpovich教授、Jason J.Pagano、Christopher H.Schilling、Tami L.Sivy和Ron R.Williams将获得一台拉曼光谱仪、一台热重分析仪(TGA)和一台差示扫描量热仪(DSC)。这些仪器将用于研究从区域农业和生物燃料废物中生产新型可生物降解塑料，并分析地质和生物系统中形成的管状沉淀结构。拉曼光谱、热重分析和差示扫描量热法将用于将与材料中特定的分子间相互作用和转变相关的光谱和热性质与其物理/机械性质相关联。拉曼光谱提供了有关材料的化学成分和结构的信息。热重分析(TGA)测量作为温度函数的材料的重量变化，提供有关样品受热时分解或蒸发的信息。差示扫描量热仪(DSC)测量提高材料温度所需的热量，并帮助识别物理变化，如相变。这些仪器的组合使用将有助于提高生物塑料的性能，优化其拉伸强度并降低脆性。
