IMREL-CHRNS Partnership for Research and Education in Materials (IC-PREM) using a National Facility

费耶特维尔州立大学(FSU)是一所为少数群体服务的机构，70%以上的学生被归类为少数群体，主要是非裔美国人，女性、军人或与军方有关联的学生人数较多。这一奖项授予FSU，通过NSF材料研究和教育伙伴关系(PREM)计划支持纳米材料的中子散射研究。建立的伙伴关系是由NSF资助的FSU跨学科材料研究和教育实验室(IMREL)与高分辨率中子散射中心(CHRNS)之间的定义，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拥有用于纳米材料研究的材料合成、制造、加工、表征和性能测量的设备和仪器，而CHRNS向一般科学界提供最先进的中子散射仪器，在材料研究中有广泛的应用，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访问CHRNS，并与CHRNS的科学家一起使用CHRNS的中子散射对各种合成纳米材料进行现场合作研究。FSU的设施还将提供给与CHRNS有关联的科学家和CHRNS用户社区，以便在FSU进行必要的补充研究。这一IMREL-CHRNS PREM(IC-PREM)项目将提高材料研究能力，促进外国语大学的科学、技术、工程和数学(STEM)教育。本次PREM项目利用国家用户设备CHRNS加强少数民族教育，研究重点是利用CHRNS上的中子散射来了解纳米材料的结构-加工-性能关系。IMREL和CHRNS的研究人员已经确定了在以下三个主要领域进行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)二维杂化钙钛矿的光电性能；以及(3)纳米材料假晶的合成、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通过精心定制的无机纳米钙钛矿纳米纤维结构来增强新的物理化学性质；通过研究同位素效应、阳离子取代、结构缺陷和结构维度来潜在地发现二维杂化钙钛矿的新的光电性质；以及通过纳米晶的表面修饰来实现增强的电、光和热性能。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，而其他方法无法用来指导每个研究领域的研究。这一奖项反映了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。

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.
