项目摘要

NON-TECHNICAL SUMMARY:This Major Research Instrumentation (MRI) award is to acquire a multifunctional X-ray diffractometer that will enhance research and education activities at Morgan State University. The requested instrument will be crucial in fulfilling the needs of advanced structural characterizations of various types of functional materials developed by scientists at Morgan State University and their partners at other collaborating institutions. This instrumentation award will consolidate the existing research collaboration between Morgan’s scientists and their partners at neighboring institutions and allow the establishment of new alliances with other academic institutions and the industrial sector. In addition to benefiting the university and its collaborators, the acquisition of this instrumentation will positively impact other sectors. The requested funds will enhance the research infrastructure of Morgan State University, which is an HBCU, and will offer research opportunities and training to minority students. It will boost junior faculty development at this institution. This will promote greater participation in materials science by African-Americans, who are underrepresented in this field of science. This instrument will increase the competitiveness of minority students in the functional materials field at Morgan State. This will significantly enhance the opportunities for African-American graduates in the job market.TECHNICAL SUMMARY:The multifunctional X-ray diffractometer to be acquired includes all typical scans offered by a four-circle diffractometer in addition to the capability of high temperature measurement. The PIs and the senior personnel of this grant are scientists from Morgan State University and Loyola University Maryland with research interests in materials such as ferromagnets, highly magnetostrictive alloys, nanomaterials, thermo-electrics, low-dimensional hetero-structures, porous materials, magneto-electrics, and optical materials. The equipment will be used to fulfill the needs of advanced structural characterization of various types of materials under development by the PIs and their research partners, as well as to provide research training to students, postdocs and faculty. The multifunctional diffractometer will play a key role in investigating the structural properties of these materials by conducting the following measurements. (1) The four-circle diffractometer scans will enable the determination of the materials' structure, quantify strain in heterostructures, determine the crystallographic orientation and epitaxy, and map the distribution of crystallites in the investigated materials. (2) The high temperature capability of the requested instrument will be crucial in investigating phase transition and determining structural changes accompanying this transition in functional materials. All these measurements together with other analyses offered by facilities at the PIs' and the senior personnel institutions will be crucial in conducting cutting-edge research and advancing scientific knowledge in the field of functional materials. This will enable engineering new advanced materials with superior performances, which will benefit the industrial sector.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

非技术摘要：这项主要研究仪器(MRI)奖是为了获得一台多功能X射线衍射仪，该衍射仪将加强摩根州立大学的研究和教育活动。所要求的仪器将对满足摩根州立大学的科学家及其在其他合作机构的合作伙伴开发的各种功能材料的高级结构表征的需要至关重要。这项仪器奖将巩固摩根的科学家和他们在邻近机构的合作伙伴之间的现有研究合作，并允许与其他学术机构和工业部门建立新的联盟。除了使该大学及其合作者受益外，收购这一仪器还将对其他部门产生积极影响。申请的资金将加强作为HBCU的摩根州立大学的研究基础设施，并将为少数族裔学生提供研究机会和培训。它将促进该机构的初级教师发展。这将促进非洲裔美国人更多地参与材料科学，他们在这一科学领域的代表性不足。这一工具将提高摩根州立大学少数族裔学生在功能材料领域的竞争力。这将大大增加非裔美国毕业生在就业市场上的机会。技术摘要：即将购买的多功能X射线衍射仪除了具有高温测量能力外，还包括四圈衍射仪提供的所有典型扫描。PIs和这项资助的高级人员是来自摩根州立大学和马里兰州洛约拉大学的科学家，他们对铁磁体、高磁致伸缩合金、纳米材料、热电学、低维异质结构、多孔材料、磁电学和光学材料等材料有研究兴趣。该设备将用于满足私人投资机构及其研究伙伴正在开发的各种材料的高级结构表征的需求，以及为学生、博士后和教师提供研究培训。多功能衍射仪将通过进行以下测量，在研究这些材料的结构特性方面发挥关键作用。(1)四圆衍射仪扫描将能够确定材料的结构，量化异质结构中的应变，确定晶体取向和外延，并绘制所研究材料中的微晶分布图。(2)所要求的仪器的高温能力将在研究相变和确定伴随功能材料的相变的结构变化中起关键作用。所有这些测量，加上私人投资机构和高级人事机构的设施提供的其他分析，将对开展尖端研究和增进功能材料领域的科学知识至关重要。这将使设计出性能优越的新型先进材料，这将使工业部门受益。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
