项目摘要

Non-technical Summary:Hampton University is a private Historically Black College and University (HBCU) founded in 1868 with the mission to educate African-Americans who would go out and teach and lead people within their community. The university is a comprehensive institution of higher education, dedicated to the promotion of learning, building of character and preparation of promising students for positions of leadership and service. The Hampton-Brandeis Partnership for Research & Education in Materials (PREM) between Hampton University and Brandeis University Materials Research Science & Engineering Center (MRSEC) includes the strengthening and expansion of collaborative research and education between these two institutions. The overall goal of the Hampton-Brandeis PREM is to increase recruitment, retention, and graduation rates of talented minority students in materials science and engineering related fields. In addition, an important ancillary goal is to increase the research capacity and productivity at Hampton. The PREM will increase the number of African-American and women students in materials science and engineering research careers and markedly expand the supply of scientists and engineers contributing to innovation and discovery to fuel the growth of the American economy. This will be accomplished by: (1) increasing the number of undergraduate and graduate students participating in materials science research activities, (2) implementing the PREM Path-to-Professorship (PtP) Post-doctoral Fellowship Program to prepare a new cohort of early career faculty for HBCUs, (3) developing a sustainable outreach program in materials science and engineering for middle and high school students in the Hampton Roads region and (4) increasing communication of materials science and engineering to audiences across the continuum, from peers to general public, by all Hampton PREM participants. The Hampton-Brandeis PREM's overall goal is to serve as a catalyst for the recruitment and retention of talented students pursuing research careers in materials science and engineering fields. Technical Summary:The Hampton-Brandeis PREM research seeks to study the photo-responsive, opto-active, and optoelectric properties of photonic materials for microfluidic and optofluidic applications. The proposed research for Thrust 1 aims to develop a new type of photoswitchable low-molecular-weight-gelators by integrating dipeptide derivatives which are known to be versatile self-assembly motifs, with a novel family of arylazopyrazole based molecular photoswitches possessing metal binding functionality. In Thrust 2, opto-active biomaterials will be designed and their interactions with cells will be studied to assess their capabilities of being extracellular matrix surrogates, through metrics such as degradation, growth factor release and adaptable/tunable mechanical properties. Fluorogenic protease-sensitive peptide (FPSP) sequences will be developed, and subsequently, the critical cross link density of FPSPs in polyurethane casts will be determined to visualize/quantify cellular proteolytic activity in real-time. Thrust 3, which focuses on opto-electronic materials, will investigate mixed halide perovskites and semiconductors. The proposed research on the development of mixed halide perovskites will include purification studies of commercial precursors, solution-based synthesis, solid-state mechano-chemical synthesis, and crystallization from the melt. Doping studies using rare earth and transition metal ions will be performed to explore improved long-term stability as well as extended emission wavelength coverage in the UV-VIS and IR spectral region. In addition, the research will focus on the characterization of silicon, compound semiconductors, and mixed halide perovskite materials for optofluidic applications. The study aims to determine the optical properties (emission, absorption, transparency, etc.), mechanical properties to support microfluidic fabrication processes, and the electrical properties for circuitry and heterogeneous interfacing of materials. Lastly, research will be conducted to explore how the identities (science, racial and gender) of minority materials science undergraduates and their participation in PREM impact their recruitment, retention and achievement in materials science.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：汉普顿大学是一所私立历史黑人学院和大学 (HBCU)，成立于 1868 年，其使命是教育非裔美国人，让他们走出去，在社区内教学和领导人们。该大学是一所综合性高等教育机构，致力于促进学习、培养品格并为有前途的学生担任领导和服务职位做好准备。汉普顿大学和布兰迪斯大学材料研究科学与工程中心（MRSEC）之间的汉普顿-布兰迪斯材料研究与教育合作伙伴关系（PREM）包括加强和扩大这两个机构之间的合作研究和教育。汉普顿-布兰迪斯 PREM 的总体目标是提高材料科学和工程相关领域优秀少数族裔学生的招聘、保留和毕业率。此外，一个重要的辅助目标是提高汉普顿的研究能力和生产力。 PREM 将增加从事材料科学和工程研究职业的非裔美国人和女学生的数量，并显着增加为创新和发现做出贡献的科学家和工程师的供应，从而推动美国经济的增长。这将通过以下方式实现：(1) 增加参与材料科学研究活动的本科生和研究生数量，(2) 实施 PREM 教授之路 (PtP) 博士后奖学金计划，为 HBCU 培养一批新的早期职业教师，(3) 为汉普顿路地区的中学生和高中生制定可持续的材料科学与工程外展计划，以及 (4) 加强材料交流所有汉普顿 PREM 参与者都向从同行到普通公众的整个连续体的观众传播科学和工程知识。汉普顿-布兰迪斯 PREM 的总体目标是成为招募和保留在材料科学和工程领域从事研究职业的优秀学生的催化剂。技术摘要：Hampton-Brandeis PREM 研究旨在研究用于微流体和光流体应用的光子材料的光响应、光活性和光电特性。 Thrust 1的拟议研究旨在通过将已知的多功能自组装基序的二肽衍生物与具有金属结合功能的基于芳基偶氮吡唑的新型分子光开关家族相结合，开发一种新型光可开关低分子量胶凝剂。在 Thrust 2 中，将设计光活性生物材料，并研究它们与细胞的相互作用，通过降解、生长因子释放和适应性/可调机械性能等指标来评估它们作为细胞外基质替代物的能力。将开发荧光蛋白酶敏感肽 (FPSP) 序列，随后将确定聚氨酯铸件中 FPSP 的临界交联密度，以实时可视化/量化细胞蛋白水解活性。 Thrust 3 专注于光电材料，将研究混合卤化物钙钛矿和半导体。拟议的混合卤化物钙钛矿开发研究将包括商业前体的纯化研究、基于溶液的合成、固态机械化学合成和熔体结晶。将使用稀土和过渡金属离子进行掺杂研究，以探索改善的长期稳定性以及扩展紫外-可见光和红外光谱区域的发射波长覆盖范围。此外，该研究将重点关注用于光流控应用的硅、化合物半导体和混合卤化物钙钛矿材料的表征。该研究旨在确定光学特性（发射、吸收、透明度等）、支持微流体制造工艺的机械特性以及电路和异质接口材料的电气特性。最后，我们将进行研究，探讨少数族裔材料科学本科生的身份（科学、种族和性别）以及他们对 PREM 的参与如何影响他们在材料科学领域的招募、保留和成就。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
