MRI: Acquisition of an Imaging Plate Based X-Ray Diffractometer for Use in a Materials Chemistry Research and Education Program

在重大研究仪器计划(NSF-MRI)的支持下，乔治华盛顿大学(GWU)化学系将获得一台基于成像平板(IP)的两用粉末/单晶X射线衍射仪，以促进有机、无机和材料化学领域的研究和教育。具体地说，该仪器将被用作a)混合铀氧化物材料合成；b)模板化金属-有机骨架材料；c)电活性和晶态多孔性固体；d)稀土和铁氧体纳米颗粒；e)溶液可加工半导体固体的材料设计和发现工作的关键组成部分。这些领域与气体传感、氢储存、催化、电活性材料、分子识别、磁学和乏核燃料的环境管理/补救特别相关。这种仪器的双重性质将允许在受控气氛下对这些体系进行动态、原位研究(通过粉末衍射)，以及对新的合成产品进行结构测定(通过单晶衍射)。此外，将加强和/或引入本科和研究生水平的课程，以利用这种设备，从而促进对一系列学生的培训。在主要研究仪器计划(NSF-MRI)的支持下，乔治华盛顿大学(GWU)化学系将获得一台基于成像板(IP)的两用粉末/单晶X射线衍射仪，以促进有机、无机和材料化学领域的研究和教育。有针对性的研究领域包括与气体传感、储氢、催化、电活性材料、分子识别和乏核燃料的环境管理/补救有关的新型杂化和纳米材料的合成。收购这种仪器将对我们教育和培训学生的能力产生直接和切实的影响，因为我们打算为研究生和本科生开发课程。具体地说，我们将介绍本科物理化学实验部分的新颖实验，以及以X射线衍射为核心技术的高级材料表征课程。

With support from the Major Research Instrumentation Program (NSF-MRI), the Chemistry Department at the George Washington University (GWU) will acquire an imaging plate (IP) based, dual purpose powder/single crystal X-ray diffractometer to promote research and education in the areas of organic, inorganic and materials chemistry. Specifically, the instrumentation will be utilized as a key component of materials design and discovery efforts in a) hybrid uranium oxide materials synthesis; b) templated metal-organic framework materials; c) electroactive and crystalline porous solids; d) lanthanide and ferrite nanoparticles; e) solution processable semiconductive solids. These areas have particular relevance to gas sensing, hydrogen storage, catalysis, electroactive materials, molecular recognition, magnetics and environmental stewardship/remediation of spent nuclear fuel. The dual nature of this instrumentation will allow dynamic, in situ studies of these systems (via powder diffraction) under controlled atmospheres as well as structure determination of novel synthetic products (via single crystal diffraction). Further, courses at the undergraduate and graduate levels will be enhanced and/or introduced to make use of this equipment and hence facilitate training for a range of students.With support from the Major Research Instrumentation Program (NSF-MRI), the Chemistry Department at the George Washington University (GWU) will acquire an imaging plate (IP) based, dual purpose powder/single crystal X-ray diffractometer to promote research and education in the areas of organic, inorganic and materials chemistry. Targeted research areas include the synthesis of novel hybrid- and nano-materials with relevance to gas sensing, hydrogen storage, catalysis, electroactive materials, molecular recognition and environmental stewardship/remediation of spent nuclear fuel. Acquisition of this instrumentation will have an immediate and tangible impact on our ability to educate and train students in x-ray crystallography as we intend to develop courses for both graduate and undergraduate students. Specifically, novel experiments for our undergraduate Physical Chemistry Laboratory sections will be introduced, as will an advanced materials characterization course with x-ray diffraction as the central technique.
