Nanostructures can have different properties to those of bulk materials. This can derive from quantum size effects or simply from a difference in structure adopted as the size of a cluster decreases. There are many possible applications of these phenomena; for metal oxide nanostructures these include advanced sensors, catalysts, high-density visual displays, memory storage devices and environmental control. There is a clear need to understand the structure/function relationship of nanostructures in support of these applications. In this project, a new instrument, The Nanoscience Beamline, which is located at the diamond light source will be used to examine some topics related to nanocatalysis. These measurements will also provide a means to train a new scientist in this area. The beamline uses a technique called X-ray photoelectron microscopy (XPEEM), which can examine the chemical state of a surface in an area down to 20 nanometers (one nanometer is a billionth of a meter).

纳米结构可以具有与块体材料不同的性质。这可能来自量子尺寸效应，或者简单地来自随着团簇尺寸减小而采用的结构差异。这些现象有许多可能的应用;对于金属氧化物纳米结构，这些包括先进的传感器，催化剂，高密度视觉显示器，记忆存储设备和环境控制。有一个明确的需要，以了解支持这些应用程序的纳米结构的结构/功能关系。在这个项目中，一个新的仪器，纳米科学光束线，这是位于钻石光源将被用来检查一些有关纳米催化的主题。这些测量还将为培训这一领域的新科学家提供一种手段。光束线使用一种称为X射线光电子显微镜（XPEEM）的技术，可以检查表面的化学状态，范围低至20纳米（一纳米是十亿分之一米）。
