With this award from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at the University of Maryland in College Park will acquire an X-ray photoelectron spectrometer. This equipment will enhance research in a number of areas: a) nanostructure reactivity and registration at solid surfaces; b) derivatization of metal and metal oxide surfaces via molecular and mesoscopic self assembly; c) chemical vapor deposition of metal oxides; d) combinatorial synthesis of functional oxides; and e) soft chemical routes to novel solid state materials. The X-ray photoelectron spectrometer (XPS) is used for chemical analysis. It irradiates a sample with a beam of monochromatic X-rays and the energies of the resulting photoelectrons are measured and related to specific elements. XPS often plays a crucial role in defining the system under study. The work to be carried out by these investigators represents a highly coherent attack on a range of issues at the forefront of materials chemistry.

有了这项来自主要研究仪器（MRI）计划的奖项，位于学院公园的马里兰州大学化学系将获得一台X射线光电子能谱仪。这一设备将加强若干领域的研究：a）纳米结构反应性和固体表面的记录; B）通过分子和介观自组装对金属和金属氧化物表面进行衍生; c）金属氧化物的化学气相沉积; d）功能氧化物的组合合成; e）新型固态材料的软化学途径。 X射线光电子能谱仪（XPS）用于化学分析。 它用一束单色X射线照射样品，测量产生的光电子的能量并将其与特定元素联系起来。 XPS通常在定义所研究的系统方面起着至关重要的作用。 这些研究人员将要开展的工作代表了对材料化学前沿一系列问题的高度一致的攻击。
