Acquisition of a Regional-use Surface Analysis System

在化学研究仪器和设施-多用户仪器获取(CRIF-MU)计划的支持下，犹他大学化学系将购买具有ISS(离子散射光谱)的集成成像X射线光电子能谱(XPS)和扫描俄歇微探针(SAM)系统。该设备将用于一些研究项目，包括a)有机磁性材料；b)对环境敏感的纳米孔；c)形状记忆合金(SMA)薄膜结构的结晶学模板；d)硅表面的图案化和功能化；e)胶体和胶体衍生结构的界面化学；f)室温离子液体。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。这些研究人员将开展的工作代表着对纳米技术和环境化学前沿的一系列问题的高度一致的攻击。此外，与当地行业、其他学校和地区学童的互动将产生强大的影响，远远超出犹他大学主校园的范围。

With support from the Chemistry Research Instrumentation and Facilities - Multiuser Instrument Acquisition (CRIF-MU) Program, the Department of Chemistry at the University of Utah will purchase an integrated imaging X-ray Photoelectron Spectroscopy (XPS) and Scanning Auger Microprobe (SAM) system with ISS (Ion Scattering Spectroscopy). This equipment will be used in a number of research projects, including studies on a) organic-based magnetic materials; b) environmentally responsive nanopores; c) crystallographic-templating of shape memory alloy (SMA) thin film structures; d) patterning and functionalization of silicon surfaces; e) interfacial chemistry of colloids and colloid-derived structures; and f) room temperature ionic liquids. 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 nanotechnology and environmental chemistry. In addition, the interactions with local industry, other schools and area school children will result in a strong impact well beyond the University of Utah main campus.
