Gable教授和他的同事将获得一个多用途x射线系统，该系统采用交叉光束光学技术，能够进行平行和聚焦光束实验。该仪器还将配备研究薄膜的附件，对纳米材料进行小角度x射线散射（SAXS）实验，并检查其性能作为温度的函数。该仪器将用于支持以下研究活动：1)无机薄膜、图案和器件的溶液沉积2)宽带隙双极半导体的合成和研究；3)利用主基团纳米团簇作为薄膜的溶液前驱体；4)石墨插层化学；5)小型分析装置和微反应器的开发；6)各种无机功能材料的表征。x射线系统可以精确测量粉末、薄膜和纳米形式的材料。完整的三维结构的化合物，以提供精确的键的距离和角度。通过对散射条纹的定量分析以及密度和表面平滑度的测量来评估薄膜质量。评价纳米层合材料的结构和相互扩散过程提供了反应动力学的基本信息。纳米材料和纳米棒的大小和形状可以快速评估，以评估控制生长的反应条件。这里描述的研究将影响许多领域，包括基于溶液的分子化学和固态材料化学。该仪器将成为教学和研究的一个组成部分。

With this award from the Chemistry Research Instrumentation and Facilities: Departmental Multi-User Instrumentation program (CRIF:MU), Professor Kevin P. Gable and colleagues from Oregon State University will acquire a multipurpose X-ray system with cross-beam optical technology that will be able to perform parallel and focusing beam experiments. The instrument will also have attachments for studying thin films, performing small angle X-ray scattering (SAXS) experiments on nanomaterials, and examining properties as a function of temperature. The instrument will be used to support research activities such as: 1) solution deposition of inorganic thin films, patterns, and devices 2) synthesis and study of wide band-gap bipolar semiconductors; 3) use of main-group nanoclusters as solution precursors for thin films; 4) graphite intercalation chemistry; 5) development of small-scale analytical devices and microreactors; and 6) characterization of a variety of inorganic functional materials.The X-ray system allows accurate and precise measurements of materials in powder, thin-film, and nano forms. Full three-dimensional structures of a compound are refined to provide accurate bond distances and angles. Film quality is assessed through quantitative analysis of scattering fringes and measurements of density and surface smoothness. Evaluation of the structures and interdiffusion processes in nanolaminates provides fundamental information on reaction dynamics. The sizes and shapes of nanomaterials and rods can be quickly assessed to evaluate reaction conditions for controlled growth. The studies described here will impact a number of areas, including solution-based molecular chemistry and solid-state materials chemistry. This instrument will be an integral part of teaching as well as research.
