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.

非技术摘要 该重大研究仪器项目资助在西华盛顿大学购买差示扫描量热计 (DSC)。 DSC 是一种根据样品进出热量随时间和温度的变化来分析材料热转变的技术。这些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 和其他先进仪器由先进材料科学与工程中心 (AMSEC) 管理的 WWU 仪器集群维护，该中心为广泛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、生物材料科学和环境科学。 DSC 还将在本科生 STEM 课程中广泛使用，并支持本科生实践研究。该仪器将作为 WWU 的重要资源，支持热表征以支持 10 多个研究项目，并成为多元化教育环境不可或缺的一部分。 DSC 还支持与工业合作伙伴的应用研究，以提高制造商的国际竞争力并加快能源和可持续发展等关键领域材料的开发。技术摘要差示扫描量热法 (DSC) 是一种基本表征方法，用于测量热转变，例如玻璃化转变、结晶、熔化、材料热稳定性、反应和相变动力学以及多种材料的氧化/热稳定性。与旧仪器相比，新型 DSC 提供了更多可重复的数据，具有改进的信噪比和保真度，具有增强的分辨率和灵敏度，并且样品吞吐量增加了三倍。从用途来看，最大的需求来自以下研究领域：高分子科学与工程、材料表征、纳米材料与化学合成、环境科学。将立即使用 DSC 的具体研究项目包括 vitrimer 和共价自适应网络材料开发、新型聚合物和树脂的化学合成、航空航天复合材料表征（热塑性和热固性材料）、材料回收和可持续性工作、生物医学材料应用、半导体材料纳米复合材料开发、增材制造材料开发以及微塑料的环境归宿和处置。该奖项通过支持基础材料研究以及符合国家利益的应用工业研究来强化 NSF 的使命，并为研究人员和实验室课程的本科生提供实践研究培训。该奖项反映了 NSF 的法定使命，并已通过使用基金会的智力优点和更广泛的影响审查标准进行评估，认为值得支持。
