Research Initiation Awards (RIAs) provide support for junior faculty at Historically Black Colleges and Universities (HBCUs) who are starting to build a research program, as well as for mid-career faculty who need to re-direct and re-build a research program. It is expected that the award helps to further the faculty member's research capability and effectiveness, improves research and teaching at the researcher's home institution, and involves undergraduate students in research experiences.Tuskegee University's RIA project, within the Department of Materials Science and Engineering (MSE), develops its research capabilities in Computational Nanomechanics and Nanoscale Testing, areas of research which are essential to the development of a deeper understanding of the interaction of nano fillers with the matrix materials and their role in enhancing the mechanical properties of composite structures. Specific activities undertaken through this project include: 1) Setting up the initial structure with various amounts of cross-linking between SWCNT and Epon molecule and with varying diameters of SWCNT, 2) Determination of interfacial binding energy and frictional stresses between carboxylic (COOH) functionalized SWCNT and Epon composites,3) Measurement of frictional stresses as a function of the density of chemical bonds between COOH-SWCNT and Epon composites, 4) Quantification of how these stresses scale with the surface area of COOH-SWCNT, 5) Determination of interfacial strength using fiber pull-out and nanoindentation tests to compare the trends in shear strength with respect to SWCNT size and density of interfacial bonds observed in MD simulations, and6) Involvement of undergraduate students in this research.The project is a collaboration with the University of Wisconsin-Madison, the Air Force Research Laboratory and the NSF funded Materials for Information Technology (MINT) Center at University of Alabama.Development of a competent and diverse workforce in MSE is very critical for the United States to maintain global competitive edge. The RIA allows TU to introduce new research areas and academic courses to prepare undergraduate students who can compete successfully in the global market. A robust infrastructure and expertise exists at the institution in cutting-edge research in various aspects of advanced materials that are of interest to the military, automobile, sports, civil and healthcare industries. In addition to broadening participation through the inclusion and development of underrepresented minorities in STEM, the institution broadens participation in STEM geographically as an Experimental Program to Stimulate Competitive Research (EPSCoR) jurisdiction.Dissemination of research and education outcomes generated from the project?s implementation will be available in several venues including publications in refereed journals and presentations, including student research presentations, at national and international conferences.

研究启动奖 (RIA) 为历史悠久的黑人学院和大学 (HBCU) 开始建立研究项目的初级教师以及需要重新指导和重建研究项目的职业中期教师提供支持。 预计该奖项有助于提高教职人员的研究能力和效率，改善研究人员所在机构的研究和教学，并让本科生参与研究经验。塔斯基吉大学材料科学与工程系 (MSE) 的 RIA 项目），发展其在计算纳米力学和纳米级测试方面的研究能力，这些研究领域对于更深入地了解纳米填料与基体材料的相互作用及其在增强复合材料机械性能方面的作用至关重要结构。通过该项目开展的具体活动包括：1) 建立具有不同数量的 SWCNT 和 Epon 分子之间的交联以及不同直径的 SWCNT 的初始结构，2) 测定羧基 (COOH) 官能化之间的界面结合能和摩擦应力SWCNT 和 Epon 复合材料，3) 测量摩擦应力作为 COOH-SWCNT 和 Epon 复合材料之间化学键密度的函数，4) 量化这些应力如何随表面面积变化COOH-SWCNT，5) 使用纤维拉拔和纳米压痕测试确定界面强度，以比较在 MD 模拟中观察到的 SWCNT 尺寸和界面键密度的剪切强度趋势，以及 6) 本科生参与这项研究。该项目是与威斯康星大学麦迪逊分校、空军研究实验室和美国国家科学基金会资助的阿拉巴马大学信息技术材料 (MINT) 中心合作进行的。 MSE 的劳动力对于美国保持全球竞争优势至关重要。 RIA 允许 TU 引入新的研究领域和学术课程，为本科生做好在全球市场竞争中取得成功的准备。 该机构在军事、汽车、体育、民用和医疗保健行业感兴趣的先进材料各个方面的尖端研究方面拥有强大的基础设施和专业知识。 除了通过纳入和发展 STEM 中代表性不足的少数群体来扩大参与范围外，该机构还作为刺激竞争性研究实验计划 (EPSCoR) 管辖范围扩大了 STEM 的参与范围。项目实施过程中产生的研究和教育成果的传播将可以在多个场所获得，包括在受审期刊上发表出版物和在国内和国际会议上发表演讲，包括学生研究演讲。
