Nanomaterials such as nanoparticles and nanoclusters are the most widely used building blocks in current nanotechnology. Improved understanding of the structure-property relationships of nanomaterials is crucial for advancing nanotechnology. This proposed research program focuses on the use of powerful synchrotron radiation (the "brightest" light) based X-ray spectroscopy techniques to uncover the structure-property relationships of some technologically important nanomaterials. Three classes of nano-systems will be studied, including (i) catalytically active nanoparticles, (ii) bio-inspired nanostructures (iii) composition-precise gold and silver nanoclusters. By using the synchrotron spectroscopy techniques that we recently established in conjunction with conventional techniques outlined in this proposal, it is anticipated that significantly improved understanding of the structure-property relationships of the above three classes of nano-systems will be resulted, which will make important contributions to the fundamental research in physical chemistry and materials science. The proposed research will also improve the development of nanometer-sized catalysts and biological devices, thus accelerating the advancement of nanotechnology in Canada.

纳米材料（例如纳米颗粒和纳米簇）是当前纳米技术中使用最广泛的构件。对纳米材料的结构特性关系的提高了解对于推进纳米技术至关重要。该提出的研究计划着重于使用强大的同步加速器辐射（基于“最亮”）的X射线光谱技术，以揭示某些具有技术重要的纳米材料的结构 - 质体关系。将研究三类的纳米系统，包括（i）催化活性纳米颗粒，（ii）生物启发的纳米结构（III）成分构成精致的黄金和银纳米群。通过使用我们最近与本提案中概述的常规技术建立的同步加速器分类技术，可以预见，将产生对上述三类纳米系统的结构 - 培训关系的显着提高，这将产生对物理化学化学和材料科学的基本研究的重要作用。拟议的研究还将改善纳米大小的催化剂和生物设备的发展，从而加速加拿大纳米技术的发展。
