NON-TECHNICAL SUMMARY This major research instrumentation project funds the acquisition of a differential scanning calorimeter (DSC) at Western Washington University. DSC is a technique for analysis of thermal transitions in materials based on changes in heat into and out of samples as a function of time and temperature. The data can be readily translated into fundamental properties of materials, and thus it is a vital tool for materials research. The DSC and other advanced instruments are maintained within the WWU instrumentation cluster managed by the Advanced Materials Science and Engineering Center (AMSEC) which provides core resources for investigators in a wide range of fields, including polymer synthesis, polymer and composites engineering, materials chemistry, biochemistry, biomaterial science, and environmental science. The DSC will also find widespread use in the undergraduate STEM curriculum and to support hands-on undergraduate research. This instrument will serve as a critical resource at WWU, enabling thermal characterization in support of more than 10 research programs, as well as becoming an integral part of a diverse educational environment. The DSC also supports applied research with industrial partners that promotes international competitiveness for manufacturers and speeds development of materials in critical areas such as energy and sustainability. TECHNICAL SUMMARYDifferential scanning calorimetry (DSC) is a fundamental characterization method used to measure thermal transitions such as glass transitions, crystallization, melting, material thermal stability, reaction and phase-change kinetics, and oxidative/thermal stability of a wide spectrum of materials. Compared to older instruments, the new DSC delivers more reproducible data, with improved signal-to-noise ratio and fidelity, with enhanced resolution and sensitivity, and with increased sample throughput of up to a factor of three. In terms of usage, the greatest demand comes from the following fields of research: polymer science and engineering, materials characterization, nanomaterial and chemical synthesis, and environmental science. Specific research projects that will immediately use the DSC include vitrimer and covalent adaptive network materials development, chemical synthesis of novel polymers and resins, aerospace composites characterization (both thermoplastic and thermoset materials), materials recycling and sustainability efforts, biomedical materials applications, semiconductor materials with nanocomposites development, materials development for additive manufacturing, and environmental fate and disposition of micro-plastics. This award reinforces the mission of the NSF by supporting fundamental materials research as well as applied industrial research in the national interest, and it provides hands-on research training for researchers and for undergraduates in lab classes.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.

非技术总结这个主要的研究工具项目为西华盛顿大学的差异扫描量热仪（DSC）提供了资金。 DSC是一种基于时间和温度的函数，基于热量进入和流出样品的变化，用于分析材料中的热过渡。数据可以很容易地转化为材料的基本特性，因此它是材料研究的重要工具。 DSC和其他高级仪器维护在由高级材料科学和工程中心（AMSEC）管理的WWU仪器集中，该中心为各个领域的研究人员提供核心资源，包括聚合物合成，聚合物和复合材料工程，材料化学，生物化学，生物化学，生物物质科学和环境科学。 DSC还将在本科STEM课程中广泛使用并支持动手本科研究。该工具将在WWU中充当关键资源，从而使热表征能够支持10多个研究计划，并成为多种教育环境中不可或缺的一部分。 DSC还支持与工业合作伙伴的应用研究，从而促进了制造商的国际竞争力，并加快了能源和可持续性等关键领域的材料开发。技术摘要扫描量热法（DSC）是一种基本特征方法，用于测量诸如玻璃跃迁，结晶，熔化，材料热稳定性，反应和相变动力学以及广泛材料的氧化/热稳定性。与较旧的仪器相比，新的DSC提供了更多可再现的数据，具有提高的信噪比和忠诚度，分辨率和灵敏度的提高，并增加了三分倍的样品吞吐量。在使用方面，最大的需求来自以下研究领域：聚合物科学和工程，材料表征，纳米材料和化学合成以及环境科学。将立即使用DSC的特定研究项目包括玻璃二聚体和共价适应性网络材料的开发，新型聚合物和树脂的化学合成，航空航天复合材料的特征（热塑料和热塑性和热固性材料），材料的循环利用和可持续性工作，生物医学材料应用，生物医学材料应用，与纳米组合的发展材料的材料，以及对材料的开发和增添材料的发展，以及材料的开发和外观。该奖项通过支持基本材料研究以及针对国家利益的应用工业研究来增强NSF的使命，并为研究人员和实验室课程中的本科生提供动手研究培训。该奖项反映了NSF的法定任务，并通过评估该基金会的知识分子优点和广泛的影响来评估NSF的法定任务。
