Acquisition of a Multi-User XPS System to Investigate Materials and Environmental Chemistry

有了这一重大研究仪器(MRI)计划的奖励，爱荷华大学化学系将获得一台X射线光电子能谱仪。该设备将加强以下领域的研究：a)硅表面图案化的新合成方法；b)设计通往无机材料的分子前体路线；c)大气颗粒的表面表征；以及d)环境应用中铁表面的表征。X射线光电子能谱(XPS)用于化学分析。它用一束单色X射线照射样品，产生的光电子的能量被测量并与特定的元素相关。XPS通常在定义研究中的系统方面发挥关键作用。这些调查人员将开展的工作代表着对材料化学和环境化学前沿的一系列问题的高度一致的攻击。

With this award from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at the University of Iowa will acquire an X-ray photoelectron spectrometer. This equipment will enhance research in a number of areas: a) novel synthetic methods for patterning silicon surfaces; b) design of molecular precursor routes to inorganic materials; c) surface characterization of atmospheric particulates; and d) characterization of iron surfaces in environmental applications. 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 and environmental chemistry.
