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.

该资金将使同步器和内部X射线衍射仪以及研究新材料（例如纳米结构，多晶材料和无定形材料）的方法的开发和应用。 这种新材料的开发以及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的重新思考以及新仪器和方法的开发。 X射线衍射（负责我们今天拥有的大多数晶体结构信息）在确定从小分子到蛋白质晶体的结构取得了巨大成功，并且具有理解新型材料的合成和表征的潜力。 我是Brockhouse X射线衍射和散射部门项目的PI，这是加拿大创新基金会资助的加拿大光源（CLS）的主要扩展。布罗克豪斯行业束线的调试计划于2017年中期开始。 在领导了布罗克豪斯（Brockhouse）领域的设计和建设（B. Diaz et.Al。，《科学仪器评论》 85，085104，2014）之后，我期待领导这个大型项目的调试阶段。我的小组将开发该部门的高分辨率对分布函数测量值（HR-PDF），谐振X射线衍射，原位衍射研究，高温衍射，粘土式互惠空间映射方法和三维X-- X-- X--射线衍射（3D-XRD）显微镜。拟议的资金将使我的研究生能够委托衍射端站，并利用这一最先进的加拿大基础设施的第一光。 我的小组将开发新型的X射线衍射和散射技术，以实现新材料的定量结构研究。在过去的十年中，已经看到了许多有用工具的开发和完善，例如扫描探针和高分辨率电子显微镜。同样，X射线方法也发展了，并提供了令人惊讶的结果和新功能。这是由于高度刷新同步源，新的X射线光学元件，大面积检测器和快速计算机。此外，由于X射线发电机技术，X射线光学元件和从Synchrotron设施技术中延续的复杂仪器的进步，传统的内部X射线衍射设施已经变得更加生产力。
