The broader impact of this Small Business Technology Transfer (STTR) Phase I project takes several forms. The basic product enables new hands-on undergraduate instruction in advanced x-ray methods for use in development of electrical energy storage and catalysis systems. Next, upgraded versions of this product will open a new market for use of these x-ray methods in industrial quality control and expand the market for the same methods in specialized research in academia and national labs. Likely applications include quality control for lithium-ion-battery components, research into catalysts and electrocatalysts in the clean energy sector, and rapid screening of engineered nanophases for many applications spanning from clean energy to consumer products. The proposed project addresses the core problem posed by the absence of entry-level capability for the advanced x-ray method known as x-ray absorption fine structure, or XAFS. Here, by entry level, we mean suitable in cost and performance for use in undergraduate education in advanced instructional laboratories in chemistry, physics, chemical engineering and materials science, or similarly suitable for use in certain applications in industry and academia where very high access but relatively low technical capability is required. We will build on existing prototype capabilities to develop miniaturized benchtop XAFS capability capable of attaching to an existing x-ray diffraction source. Effort will include testing of different optical and detector components and work to decrease background scattering.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.

这个小型企业技术转移（STTR）I阶段项目的更广泛影响采用了几种形式。 基本产品可实现高级X射线方法中的新动手本科教学，用于开发电源存储和催化系统。接下来，该产品的升级版本将开辟一个新市场，用于在工业质量控制中使用这些X射线方法，并扩展学术界和国家实验室专业研究中相同方法的市场。 可能的应用包括用于锂离子 - 蝙蝠组件的质量控制，对清洁能源领域的催化剂和电催化剂的研究，以及对从清洁能源到消费产品的许多应用进行工程纳米相的快速筛选。 所提出的项目解决了由于缺少入门级功能的高级X射线方法所带来的核心问题，称为X射线吸收精细结构或XAFS。 在这里，按入门级别，我们的意思是适用于化学，物理，化学工程和材料科学的高级教学实验室的本科教育的成本和绩效，或类似地适用于在行业和学术界的某些应用中使用，在这些应用中，需要很高的访问权限，但需要相对较低的技术能力。 我们将基于现有的原型功能，以开发能够连接到现有X射线衍射源的小型台式XAFS功能。 努力将包括测试不同的光学和检测器组件以及减少背景散射的工作。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响审查标准通过评估来支持的。
