Fayetteville State University (FSU) is a minority-serving institution with over 70% of students classified as minorities, primarily African Americans, and with high female, military or military-affiliated student populations. This award to FSU supports research on neutron scattering of nanomaterials through the NSF Partnerships for Research and Education in Materials (PREM) program. The established partnership is defined between the Interdisciplinary Materials Research and Education Laboratory (IMREL) at FSU funded by NSF, and the Center for High Resolution Neutron Scattering (CHRNS), a national user facility co-funded by NSF and by the NIST (National Institute of Standards and Technology) Center for Neutron Research (NCNR). The IMREL houses equipment and instrumentation for materials synthesis, fabrication, processing, characterization and property measurements for nanomaterials research, and CHRNS provides state-of-the-art neutron scattering instrumentation to the general scientific community with broad applications in materials research, such as polymers, metals, ceramics, magnetic materials, porous media, fluids and gels, and biological molecules. The FSU investigators and undergraduate students are supported to visit and conduct onsite collaborative research annually with CHRNS scientists on various synthesized nanomaterials using neutron scattering at CHRNS. FSU's facilities will also be made available to CHRNS-affiliated scientists and to the CHRNS user community for complementary research at FSU as needed. This IMREL-CHRNS PREM (IC-PREM) project will enhance the materials research capacities and promote the education in Science, Technology, Engineering and Mathematics (STEM) at FSU. The national user facility CHRNS is utilized to enhance the minority education in this PREM project.The research focus in this project is to use the neutron scattering at CHRNS to understand the structure-processing-property relationship of nanomaterials. The IMREL and CHRNS investigators have identified research directions with mutual interests for synergistic collaborations in these three thrust areas: (1) tailoring one-dimensional inorganic perovskite nanofibers for enhanced physical and chemical properties; (2) optoelectronic properties of two-dimensional hybrid perovskites; and (3) synthesis, manipulation, and characterization of nanomaterial pseudocrystals. These fundamental research projects will explore new enhanced physical and chemical properties by delicately tailored inorganic nanoscale perovskite nanofiber architectures through changing the shape, dimensionality, size, processing and chemical doping; potentially find new optoelectronic properties of two-dimensional hybrid perovskites through the study of isotope effects, cation substitution, structural defects and structural dimensionality; and achieve enhanced electrical, optical and thermal properties through surface modifications with nanocrystals. Neutron scattering by the partner, CHRNS, is a centerpiece method to characterize these crystalline and magnetic nanostructures that cannot be done by other means to guide the investigations in each of the research areas.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.

费耶特维尔州立大学（FSU）是一所少数民族服务机构，超过70%的学生被列为少数民族，主要是非洲裔美国人，女性，军事或军事附属学生人数较多。该奖项FSU通过NSF材料研究和教育合作伙伴关系（PREM）计划支持纳米材料的中子散射研究。建立的合作伙伴关系是由NSF资助的FSU跨学科材料研究和教育实验室（IMREL）和高分辨率中子散射中心（CHRNS）之间定义的，CHRNS是由NSF和NIST（国家标准与技术研究所）中子研究中心（NCNR）共同资助的国家用户设施。IMREL为纳米材料研究提供材料合成，制造，加工，表征和性能测量的设备和仪器，CHRNS为一般科学界提供最先进的中子散射仪器，在材料研究中具有广泛的应用，如聚合物，金属，陶瓷，磁性材料，多孔介质，流体和凝胶，以及生物分子。FSU的研究人员和本科生每年都可以与CHRNS的科学家一起访问并进行现场合作研究，研究使用CHRNS中子散射的各种合成纳米材料。FSU的设施也将提供给CHRNS附属的科学家和CHRNS用户社区，以便根据需要在FSU进行补充研究。该IMPLE-CHRNS PREM（IC-PREM）项目将提高材料研究能力，促进FSU科学，技术，工程和数学（STEM）教育。本项目利用国家级用户设备CHRNS加强少数民族教育，重点研究利用CHRNS的中子散射来理解纳米材料的结构-加工-性能关系。IMREL和CHRNS研究人员已经确定了在这三个重点领域协同合作的共同兴趣的研究方向：（1）定制一维无机钙钛矿纳米纤维以增强物理和化学性能;（2）二维混合钙钛矿的光电性能;和（3）纳米材料假晶体的合成，操作和表征。这些基础研究项目将通过改变形状、维度、尺寸、加工和化学掺杂来探索精细定制的无机纳米钙钛矿结构的新的增强的物理和化学性质;通过研究同位素效应、阳离子取代、结构缺陷和结构维度，潜在地发现二维杂化钙钛矿的新的光电性质;并通过用纳米晶体进行表面改性来实现增强的电学、光学和热学性质。合作伙伴CHRNS的中子散射是表征这些晶体和磁性纳米结构的核心方法，无法通过其他手段来指导每个研究领域的研究。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
