Differential scanning calorimeter

这项申请是为了购买差示扫描量热仪(DSC)，以取代我们过时的仪器。DSC是一种热分析技术，在任何聚合物或材料实验室都是不可或缺的。它提供了有关材料的热性能的关键信息，如它们的玻璃化转变和熔化温度，并允许深入研究它们的结构和动力学。直到最近，我们五位聚合物科学家共享了两台旧的DSC仪器，并充分利用了它们。其中一台现在已经停用了，所以我们只能接触到一台已经过时了13年的仪器。尽管进行了多次维修，但它的性能已经退化到不再提供进行大多数实验所需的灵敏度、稳定性和灵活性的地步。因此，我们对新的DSC的需求对我们的研究进展来说是迫切和关键的。在我们的研究计划中，我们开发和表征具有非凡性能和性能的新型聚合物材料，这些材料可以在高科技行业和日常生活中找到应用。这些材料包括可生物降解的聚合物和水凝胶、液晶聚合物、聚合物混合物、纳米纤维、导电材料和牙科树脂。这些项目需要广泛使用具有几个先进功能的DSC仪器，如低温冷却的可能性、调制测量、高灵敏度等。使用这种新型DSC获得的结果将极大地提高我们对聚合物物理各个方面的理解，并有助于指导我们通过研究计划开发的新材料的分子设计。此外，它还将为培养众多青年科学家做出贡献。

This application is for the acquisition of a differential scanning calorimeter (DSC) to replace our obsolete instrument. DSC is a thermal analysis technique that is indispensable in any polymer or materials laboratory. It provides crucial information about the thermal properties of materials, such as their glass transition and melting temperatures, and allows in-depth investigation of their structure and dynamics. Until recently, our group of 5 polymer scientists shared two old DSC instruments and used them to their full capacity. One of them is now defunct so that we only have access to a single, outdated, 13 year-old instrument. In spite of numerous repairs, its performance has degraded to the point that it no longer provides the sensitivity, stability and flexibility to perform most experiments. Our need for a new DSC is thus urgent and critical to the progress of our research. In our research programs, we develop and characterize new polymeric materials with unusual properties and performance that can find applications in high-tech industries as well as in everyday life. These materials include biodegradable polymers and hydrogels, liquid crystalline polymers, polymer blends, nanofibers, conducting materials, and dental resins. These projects require the extensive use of a DSC instrument with several advanced features, such as the possibility of cryogenic cooling, modulated measurements, high sensitivity, etc. The results obtained with this new DSC will greatly improve our understanding of various aspects of polymer physics and help direct the molecular design of new materials developed through our research programs. In addition, it will contribute to the training of numerous young scientists.
