MRI: Acquisition of a High Resolution X-Ray Microdiffractometer System for Advanced Materials Research and Education at Drexel

技术摘要：私人投资机构计划在德雷克塞尔大学购买一套先进的高分辨率X射线微衍射仪系统，该系统带有一个二维(2D)面探测器，用于先进的材料研究和教学。目前，Drexel拥有一个充满活力的X射线衍射仪社区，有来自六个不同部门的超过25名定期用户，他们都在使用一台旧的西门子D-500粉末衍射仪，该设备安装在25年前，功能非常有限。目标系统是配备Vantec-500探测器的新布鲁克D8发现者。显微衍射、薄膜分析、小角X射线散射、高温原位测量和最新开发的2D Vantec-500探测器等一系列重要功能使该仪器成为多学科材料研究的理想选择。将受益于拟议仪器的主要研究项目包括：(1)功能纳米混杂材料的结构、形貌和性能，(2)Mn+1AXn三元碳化物和氮化物的合成、表征和建模，(3)用于太阳能电池的薄膜和纳米晶半导体，(4)用于增强功能的钙钛矿型氧化物的原子结构控制，以及(5)在独立薄膜和微悬臂梁传感器中的压电增强。如果获得批准，X射线衍射仪系统将安装在Drexel的中央研究设施(CRF)中，这是Drexel在纳米技术、生物医学、结构材料、软材料和能源技术方面的先进研究的共享仪器资源。将X射线衍射系统置于CRF的保护伞下，将使该仪器广泛地为普通科学界所使用，同时显著提高Drexel的CRF的可见度、地区重要性和用户基础。拟议中的仪器将由研究生、本科生和高中生操作，因此将产生强大的教育影响。莱曼摘要：PI建议在德雷塞尔大学购买先进的高分辨率X射线显微衍射仪(X射线衍射仪)系统，用于先进材料研究和教育。在德雷克塞尔由美国国家科学基金会资助的146个活跃的研究和教育项目中，许多项目都专注于先进材料和纳米技术研究。X射线衍射仪是这些研究和教育活动必不可少的设备。目前，Drexel拥有一个充满活力的X射线衍射仪社区，有来自六个不同部门的超过25名定期用户，他们都在使用一台旧的西门子D-500粉末衍射仪，该设备安装在25年前，功能非常有限。因此，德雷克塞尔大学迫切需要一套先进的X射线衍射仪。目标系统是新的布鲁克D8发现者。许多重要的功能使拟议的仪器成为材料研究的理想选择。此外，该仪器对物理、化学、生物医学工程、生物和能源等一般材料相关领域也具有重要意义。如果获得批准，X射线衍射仪系统将安装在Drexel的中央研究设施(CRF)中，这是Drexel在纳米技术、生物医学、结构材料、软材料和能源技术方面的先进研究的共享仪器资源。将X射线衍射系统置于CRF的保护伞下，将使该仪器广泛地为普通科学界所使用，同时显著提高Drexel的CRF的可见度、地区重要性和用户基础。拟议的工具也将被研究生、本科生和高中生使用，因此将产生强大的教育影响。

Technical Summary: The PIs propose to acquire an advanced high resolution X-ray microdiffractometer (XRD) system with a two-dimensional (2D) area detector for advanced materials research and education at Drexel University. Currently Drexel has a vibrant XRD community of more than 25 regular users from six different Drexel departments who are all working on an old Siemens D-500 Powder Diffractometer unit that was installed more than 25 years ago and has very limited capabilities. The targeted system is the NEW Bruker D8 Discover with a VANTEC-500 detector. A number of important capabilities, such as microdiffraction, thin film analysis, small angle X-ray scattering, high temperature in-situ measurement, and the newly developed 2D VANTEC-500 detector, make the proposed instrument ideal for multidisciplinary materials research. The major research projects that will benefit from the proposed instrument include: (1) Structure, Morphology and Properties of Functional Nanohybrid Materials, (2) Synthesis, Characterization, and Modeling of Mn+1AXn Ternary Carbides and Nitrides, (3) Thin Film and Nanocrystalline Semiconductors for Solar Cell Applications, (4) Control of Atomic Structure in Perovskite Oxides for Enhanced Functionality, and (5) Piezoelectric Enhancement in Freestanding Films and Microcantilever Sensors. The XRD system, if granted, will be housed in Drexel's Centralized Research Facilities (CRF), the shared instrumentation resources for advanced research in nanotechnology, biomedicine, structural materials, soft materials, and energy technologies at Drexel. Placing the XRD system under the umbrella of CRF will make the instrument widely accessible to the general scientific community while significantly enhancing the visibility, regional importance and user base of Drexel's CRF. The proposed instrument will be operated by graduate, undergraduate, and high school students, and therefore will have a strong educational impact.Layman Summary: The PIs propose to acquire an advanced high resolution X-ray microdiffractometer (XRD) system for advanced materials research and education at Drexel University.
