0076456 Martinez-Miranda This is an award for the acquisition of a scanning X-ray microbeam system. The system will be equipped with a X-Y scanning stage, a temperature controller, and an electromagnet. The system will be added on to an existing Rigaku RTP360RC with a 12 kW X-ray source. This attachment will focus the X-ray beam down to a 10 x 10 micron square spot and will allow spatially dependent diffractometry with localized high flux of X-ray for characterizing combinatorial libraries and composition-spread samples, as well as confined samples of organic and inorganic macromolecules. Work performed with the instrumentation requested will complement and expand already existing efforts in the study of composition-spread samples, nanometer structured materials and spatially confined materials at the University of Maryland College Park. The instrument will provide new and much needed capability at the institution. It enables one to obtain spatially dependent structural information and distribution of various materials phases within individual samples. It is particularly instrumental in investigating formation of various compositional phases at different sites on combinatorial libraries and mapping the structural changes and phase distribution across composition-spread samples. Students with diverse background and origin will benefit from research program based on this equipment.***

0076456 Martinez-Miranda 这是购买扫描 X 射线微束系统的奖项。该系统将配备 X-Y 扫描台、温度控制器和电磁体。 该系统将添加到现有的 Rigaku RTP360RC 上，并配备 12 kW X 射线源。该附件将 X 射线束聚焦到 10 x 10 微米的方形光斑，并允许使用局部高通量 X 射线进行空间依赖性衍射，用于表征组合库和成分扩散样品，以及有机和无机大分子的受限样品。使用所需仪器进行的工作将补充和扩展马里兰大学学院公园分校在成分扩散样品、纳米结构材料和空间受限材料研究方面的现有工作。该工具将为该机构提供急需的新能力。它使人们能够获得空间相关的结构信息以及各个样品内各种材料相的分布。它对于研究组合库上不同位点的各种成分相的形成以及绘制成分扩散样品中的结构变化和相分布特别有用。具有不同背景和出身的学生将受益于基于该设备的研究项目。***
