Technical: This project is for the acquisition of a flexible, multi-purpose powder X-ray diffractometer (PXRD) for use by researchers in the Chemistry, Physics, Anthropology departments, and the center for nanotechnology and molecular materials at Wake Forest University. The PXRD system will enhance and expand research and education in the development of (1) hybrid inorganic-organic multifunctional cluster materials for use in catalysis, energy storage, and environmental remediation using the molecular building block synthesis strategy (2) organic materials and devices for nano- and macro-electronics applications to better understand the structural features that control electrical performance, 3) materials for organic-based photovoltaics to determine the foundational basis for engineering ideal heterojunction systems for a broad range of polymer absorbers, (4) nano-composite materials formed from conducting organic polymers grown within electroactive metal organic frameworks for use as lithium insertion electrodes, and (5) the study of anthropogenic processes and enviromagnetic minerals in the geoarchaeological record. The PXRD system has capabilities for fast and reliable collection of high quality X-ray diffraction data from polycrystalline materials, thin films, and nanomaterials, and for the collection of microdiffraction data from archaeological samples. The instrument represents a cost-effective way to satisfy current and future needs of diverse users with a wide range of interests. The equipment will be used to enhance collaboration with two historically black institutions Winston Salem State University and North Carolina Agricultural and Technical State University, and with faculty and students in the nanotechnology program at Forsyth Technical Community College. A series of weekend workshops entitled "X-rays in Art, Archaeology and Axe Murders" will include topics in materials, cultural heritage and forensics.NonTechnical: This acquisition of a multipurpose powder x-ray diffractometer (PXRD) is for advancing research, education and outreach at Wake Forest University. It will increase access to shared scientific instruments; improve the quality and expand the scope of research in science and engineering; and foster the integration of research and education in research-intensive learning environments in western North Carolina. PXRD instrumentation utilizes the analytical technique of x-ray diffraction, allowing the study of a variety of samples in a nondestructive fashion to probe structure at the atomic level. This technique has evolved to include applications in areas such as new materials development, nanomaterials, polymers, thin films, drug discovery, forensics, and archaeological sciences. The multipurpose powder x-ray diffractometer will provide research capability not currently available anywhere in the northwestern part of North Carolina and represents a cost-effective approach to satisfy the diverse requirements of its users. The research programs of users from the departments of Chemistry, Physics and the WFU Center for Nanotechnology are directed at the development of multifunctional hybrid inorganic-organic materials, organic electronics, conducting polymers, and materials for photovoltaics. For researchers from the Anthropology department, the instrument enables the microanalysis of small and heterogeneous samples of cultural materials, such as artifacts. These studies can be conducted in a nondestructive fashion so that the original samples of cultural heritage can be preserved. Since the x-ray facility at WFU also serves as a key resource for researchers at other institutions in the area, the equipment will enhance collaboration with two historically black institutions (Winston Salem State University and North Carolina Agricultural and Technical state University) and with faculty and students in the nanotechnology program at Forsyth Technical Community College. The capabilities of the new instrument will be heavily utilized in a series of weekend workshops offering topics in materials and cultural heritage and forensics.

技术支持：该项目是为收购一个灵活的，多用途的粉末X射线衍射仪（PXRD）的化学，物理，人类学系的研究人员使用，以及纳米技术和分子材料中心在维克森林大学。PXRD系统将加强和扩大以下方面的研究和教育：（1）混合无机-有机多功能簇材料，用于催化，能量储存和环境修复，使用分子构建块合成策略（2）用于纳米和宏观电子应用的有机材料和器件，以更好地理解控制电气性能的结构特征，3）用于有机基光致发光的材料，以确定用于宽范围的聚合物吸收剂的工程化理想异质结系统的基础，（4）由在电活性金属有机框架内生长的导电有机聚合物形成的纳米复合材料，用作锂插入电极，（5）地质考古记录中的人类活动和环境磁性矿物研究。PXRD系统能够快速可靠地收集多晶材料、薄膜和纳米材料的高质量X射线衍射数据，并收集考古样品的微衍射数据。该工具是满足具有广泛兴趣的不同用户当前和未来需求的一种具有成本效益的方式。这些设备将用于加强与两个历史悠久的黑人机构温斯顿塞勒姆州立大学和北卡罗来纳州农业技术州立大学的合作，以及与福赛斯技术社区学院纳米技术项目的教师和学生的合作。一系列题为“艺术、考古学和斧头谋杀中的X射线”的周末研讨会将包括材料、文化遗产和法医学方面的主题。非技术性：维克森林大学此次收购多用途粉末X射线衍射仪（PXRD）是为了推进研究、教育和推广。它将增加获得共享科学仪器的机会;提高科学和工程研究的质量并扩大其范围;促进北卡罗来纳州西部研究密集型学习环境中的研究与教育相结合。PXRD仪器利用X射线衍射的分析技术，允许以非破坏性的方式研究各种样品，以探测原子水平的结构。这种技术已经发展到包括新材料开发，纳米材料，聚合物，薄膜，药物发现，法医学和考古学等领域的应用。多用途粉末X射线衍射仪将提供北卡罗来纳州西北部目前没有的研究能力，并代表了一种符合成本效益的方法，以满足其用户的不同要求。来自化学，物理和WFU纳米技术中心的用户的研究计划旨在开发多功能混合无机-有机材料，有机电子，导电聚合物和光电子材料。对于人类学系的研究人员来说，该仪器可以对文物等文化材料的小型和异质样本进行微观分析。这些研究可以以非破坏性的方式进行，以便能够保存文化遗产的原始样本。由于在WFU的X射线设施也作为在该地区的其他机构的研究人员的关键资源，该设备将加强与两个历史上黑人机构（温斯顿塞勒姆州立大学和北卡罗来纳州农业和技术州立大学）和教师和学生在纳米技术计划在福赛斯技术社区学院的合作。新仪器的能力将在一系列周末讲习班中得到充分利用，讲习班的主题是材料和文化遗产以及法医学。
