The Historically Black Colleges and Universities - Undergraduate Program (HBCU-UP) provides support to strengthen STEM undergraduate education and research at HBCUs. This project focuses on the acquisition of an X-ray diffractometer to enhance the teaching and research capabilities within the Chemistry, Forensic Biology, Forensic Chemistry and Biomedical Engineering programs. Underrepresented students in STEM will have the opportunity to conduct research with major instrumentation and have questions answered by utilizing this technique. Access to this instrument allows for students to strengthen their research background and understand the connection between theory and application by incorporating this technique into the degree program curricula. This endeavor will play a role in preparing students for the workforce and/or advanced degree programs in STEM disciplines and create local collaborations with other institutions and affiliated research centers.Project goals include the effective analysis of complex structures of novel crystalline samples synthesized from solid-state techniques by which defects can be induced via substitution or by a post-synthesis reduction step. X-ray diffraction will be used as an essential technique to monitor and identify phases within the synthetic process and gives insight to the completion of the process. The subsequent properties analyzed as a result of this technique gives valuable insight regarding the changes based on the sample’s composition, structure, stability, and local environment of atoms. Refined bond distances and angles generated from Rietveld analysis provided by the instrument will be used to provide bond valence sums and global instability indices for synthetic products and compared with computationally modeled bond valence values for optimization leading to higher impact peer-reviewed publications.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.

历史悠久的黑人学院和大学 - 本科课程（HBCU -UP）为加强HBCUS的STEM本科教育和研究提供了支持。该项目着重于获取X射线衍射仪，以增强化学，法医生物学，法医化学和生物医学工程计划中的教学和研究能力。 STEM中代表性不足的学生将有机会使用主要的仪器进行研究，并通过使用此技术回答问题。访问该工具可以使学生通过将此技术编码到学位课程课程中来加强他们的研究背景并了解理论和应用之间的联系。这项努力将在为学生准备STEM学科的劳动力和/或高级学位课程的准备工作中发挥作用，并与其他机构和会员研究中心建立本地合作。项目包括有效地分析了从固态技术中合成的新型结晶样品的复杂结构，可以通过固态技术通过替代或通过后的Seesiss redesiss reduct reducts reducts reducts reducts reducts reducts reducts reducts reducts reducts reducts reducts。 X射线衍射将被用作一种必需技术，以监测和识别合成过程中的阶段，并深入了解该过程的完成。由于该技术而分析的后续属性给出了基于样品的组成，结构，稳定性和原子本地环境的变化的价值见解。该仪器提供的RIETVELD分析产生的精制键距离和角度将用于提供合成产品的债券价值和全球不稳定指标，并与计算建模的债券价值值进行优化，从而导致对同行评审的高度浏览出版物的较高影响。该奖项反映了NSF的法定任务，反映了通过评估的构成师的构成师的构成师的构成师的构成师的范围，并具有依据。
