Development of a Scanning X-ray Microbeam for Characterization of Combinatorial Libraries and Education

0076456 Martinez-Miranda这是一项获得扫描x射线微束系统的合同。该系统将配备一个X-Y扫描台、一个温度控制器和一个电磁体。该系统将被添加到现有的Rigaku RTP360RC上，该RTP360RC具有12千瓦的x射线源。该附件将x射线束聚焦到10 x 10微米的正方形点，并允许使用局部高通量x射线进行空间依赖衍射，以表征组合文库和成分扩散样品，以及有机和无机大分子的受限样品。使用所要求的仪器进行的工作将补充和扩展马里兰大学帕克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已经存在的努力。该工具将为该机构提供新的和急需的能力。它使人们能够在单个样品中获得空间依赖的结构信息和各种材料相的分布。它特别有助于研究组合文库中不同位置的各种成分相的形成，并绘制成分分布样品的结构变化和相分布。不同背景和出身的学生将受益于基于该设备的研究项目

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.***
