Development and Application of Novel X-Ray Diffraction and Scattering Methods for the study of Crystalline, Amorphous, and Nanoscale Materials

这笔资金将用于开发和应用同步加速器和内部x射线衍射仪器和方法，以研究纳米结构、多晶材料和非晶材料等新材料。这些新材料的发展与分析工具和计算方法的进步是齐头并进的。特别是，纳米材料需要对现有工具进行彻底的重新思考，并开发新的仪器和方法。x射线衍射负责我们今天拥有的大多数晶体结构信息，在确定小分子到蛋白质晶体的结构方面取得了巨大成功，并且在理解新材料的合成和表征方面也有潜力。我是Brockhouse x射线衍射和散射部门项目的PI，这是加拿大光源（CLS）的主要扩展，由加拿大创新基金会资助。Brockhouse部门光束线的调试计划于2017年中期开始。曾领导Brockhouse部门的设计和施工（B. Diaz等）。， review of Scientific Instruments 85, 085104, 2014)，我期待着领导这个大型项目的调试阶段。我的团队将开发高分辨率对分布函数测量（HR-PDF）、共振x射线衍射、原位衍射研究、高温衍射、掠入射互反空间映射方法和三维x射线衍射（3D-XRD）显微镜的行业能力。拟议的资金将使我的研究生能够委托衍射端站，并利用这个最先进的加拿大基础设施的曙光。我的小组将开发新的x射线衍射和散射技术，使新材料的定量结构研究成为可能。在过去的十年中，许多有用的工具如扫描探针和高分辨率电子显微镜得到了发展和改进。同样，x射线方法也在不断发展，并提供了令人惊讶的结果和新的能力。这是由于高亮度同步加速器源，新的x射线光学，大面积探测器和快速计算机。此外，由于x射线发生器技术、x射线光学和同步加速器设施技术遗留下来的精密仪器的进步，传统的内部x射线衍射设备的生产效率大大提高。

The funding will enable the development and application of synchrotron and in-house x-ray diffraction instrumentation and methods to study new materials such as nanostructures, polycrystalline materials and amorphous materials.The development of such new materials and advances in analytical tools and computational methods go hand-in-hand. In particular, nanomaterials require a drastic rethinking of existing tools and the development of new instrumentation and methods. X-ray diffraction, responsible for the majority of crystal structure information we have today, has had an immense success in the determination of structures from small-molecule to protein crystals and also has potential for understanding synthesis and characterization of novel materials. I am the PI of the Brockhouse X-Ray Diffraction and Scattering Sector project, a major expansion of the Canadian Light Source (CLS) funded by the Canadian Foundation of Innovation. The commissioning of the Brockhouse Sector beamlines is scheduled to commence in the middle of 2017. Having led the design and construction of the Brockhouse Sector (B. Diaz et.al., Reviews of Scientific Instruments 85, 085104, 2014), I look forward to leading the commissioning phase of this large project. My group will develop the sector's capabilities for High-Resolution Pair Distribution Function measurements (HR-PDF), resonant x-ray diffraction, in-situ diffraction studies, high-temperature diffraction, grazing incidence reciprocal space mapping methods and three-dimensional x-ray diffraction (3D-XRD) microscopy. The proposed funding will enable my graduate students to commission the diffraction end stations and take advantage of the first-light of this state-of-the-art Canadian infrastructure. Novel x-ray diffraction and scattering techniques will be developed by my group to enable quantitative structure studies of new materials. The last decade has seen development and refinement of many useful tools such as scanning probes and high-resolution electron microscopy. Likewise, x-ray methods have evolved and have provided surprising results and new capabilities. This is due to high-brilliance synchrotron sources, new x-ray optics, large area detectors and fast computers. In addition, conventional in-house x-ray diffraction facilities have become much more productive because of advances in x-ray generator technology, x-ray optics and the sophisticated instrumentation carried over from synchrotron facility technology.
