Research Initiation Awards provide support for junior and mid-career faculty at Historically Black Colleges and Universities who are building new research programs or redirecting and rebuilding existing research programs. It is expected that the award will (1) further the faculty member's research capability and effectiveness, (2) improve research and teaching at the home institution, and (3) engage more undergraduate students from underrepresented groups in research experiences. The project from Xavier University of Louisiana, a Historically Black College/University (HBCU), seeks to explore the novelties of imidazolium-based ionic liquids that have significant potential as a “green” organic solvent for industrial applications by utilizing chemical techniques that are readily available at the institution and through collaboration with other local institutions. Furthermore, the project is designed to include undergraduate students as active researchers while providing enhancements to existing courses by integrating the results of the proposed research within those selected courses. Accordingly, the project has significant intellectual merit and broader impacts.Imidazolium-based ionic liquids are complex spatially heterogeneous liquids. In this proposal, infrared labels, particularly the C2-D probe on the cation ring, will be used to investigate how the complex microenvironment of these ionic liquids changes in response to a change in temperature or in the presence of a solvent or a dissolved gas. Analysis of the infrared response from the C-D band, both by linear and non-linear vibrational spectroscopy, supported by computational studies is expected to provide a deep molecular-level insights into the structural reorganization of these liquids in response to external stimuli like temperature and the nature of solute-solvent interactions. In doing so, the outcomes will facilitate rational application of these green solvents both in industrial and laboratory settings.This project is jointly funded by Historically Black Colleges and Universities Undergraduate Program (HBCU-UP), and the Established Program to Stimulate Competitive Research (EPSCoR).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.

研究启动奖为传统黑人学院和大学的初级和中期职业教师提供支持，他们正在建立新的研究项目或重新指导和重建现有的研究项目。预计该奖项将(1)进一步提高教师的研究能力和效率，(2)改善本国机构的研究和教学，以及(3)让更多来自代表性不足群体的本科生参与研究经验。路易斯安那州泽维尔大学（Xavier University of Louisiana）是一所历史悠久的黑人学院/大学（HBCU），该项目旨在探索咪唑基离子液体的新特性，通过利用该机构现成的化学技术以及与其他当地机构的合作，咪唑基离子液体作为一种“绿色”有机溶剂具有巨大的潜力，可用于工业应用。此外，该项目旨在将本科生作为活跃的研究人员，同时通过将拟议的研究结果整合到这些选定的课程中，为现有课程提供增强功能。因此，该项目具有重要的智力价值和更广泛的影响。咪唑类离子液体是一种复杂的空间非均相液体。在这项提议中，红外标签，特别是阳离子环上的C2-D探针，将用于研究这些离子液体的复杂微环境如何随着温度的变化或溶剂或溶解气体的存在而变化。在计算研究的支持下，通过线性和非线性振动光谱对C-D波段的红外响应进行分析，有望在分子水平上深入了解这些液体在响应外部刺激（如温度和溶质-溶剂相互作用的性质）时的结构重组。在这样做的结果将促进这些绿色溶剂在工业和实验室设置的合理应用。该项目由历史上的黑人学院和大学本科项目（HBCU-UP）和促进竞争研究的既定项目（EPSCoR）共同资助。该奖项反映了美国国家科学基金会的法定使命，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。
