俄勒冈州立大学的Kevin P.Gable教授及其同事获得了化学研究仪器和设施：系多用户仪器计划(CRIF：MU)颁发的这一奖项，他们将获得一种具有交叉光束光学技术的多用途X射线系统，该系统将能够执行平行和聚焦光束实验。该仪器还将配备附件，用于研究薄膜，对纳米材料进行小角X射线散射(SAXS)实验，并检查性能随温度的变化。该仪器将用于支持下列研究活动：1)溶液沉积无机薄膜、图案和器件2)合成和研究宽禁带双极半导体；3)使用主族纳米团簇作为薄膜的溶液前驱体；4)石墨层间化学；5)开发小型分析仪器和微反应器；6)各种无机功能材料的表征。X射线系统可以准确和精确地测量粉末、薄膜和纳米形式的材料。化合物的完整三维结构被细化，以提供准确的成键距离和角度。通过对散射条纹的定量分析以及密度和表面光滑度的测量来评估胶片质量。评价纳米层状物的结构和互扩散过程提供了关于反应动力学的基本信息。可以快速评估纳米材料和棒的大小和形状，以评估受控生长的反应条件。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不可或缺的一部分。

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.
