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 helps to further the faculty member's research capability and effectiveness, improves research and teaching at the home institution, and involves undergraduate students in research experiences. The award to Johnson C. Smith University will support research in the design of novel materials enhanced with cellulosic nano-additives. The project will also develop an undergraduate research program that will prepare undergraduate students for careers in STEM fields.The goal of the project is to investigate the addition of pyrolyzed nanocellulose materials – in the form of char residue – as an additive into high performing and high curing temperature polyimide resins and examine the resulting mechanical properties of the new polymer/char composite. The char residue of cellulose nanomaterials is an attractive additive that can be added into high performance polyimides resins, because it does not degrade at cure temperatures above 350 °C. The project will involve the integration of the char-residue into high-temperature polymers non-covalently via the pyrolysis of nanocellulosic materials into the polymeric matrices final composite. This approach opens additional opportunities for cellulose nanomaterial applications. Since the char residue has higher carbon content and surface area than the original polyimide material, its addition to the material as a reinforcement agent is expected to improve the mechanical properties of the resultant polyimide composite.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.

研究启动奖为历史上黑人学院和大学的初级和中级职业教师提供支持，他们正在建立新的研究项目或重新定向和重建现有的研究项目。预计该奖项将有助于进一步提高教师的研究能力和效率，改善家庭机构的研究和教学，并使本科生参与研究经验。 约翰逊C.史密斯大学将支持设计纤维素纳米添加剂增强的新型材料的研究。 该项目还将开发一个本科生研究项目，为本科生在STEM领域的职业生涯做准备。该项目的目标是研究将热解纳米纤维素材料（以炭残留物的形式）作为添加剂添加到高性能和高固化温度的聚酰亚胺树脂中，并检查新型聚合物/炭复合材料的机械性能。 纤维素纳米材料的残炭是一种有吸引力的添加剂，可添加到高性能聚酰亚胺树脂中，因为它在高于350 °C的固化温度下不会降解。该项目将涉及通过将纳米纤维素材料热解成聚合物基质最终复合材料，将炭渣非共价地整合到高温聚合物中。 这种方法为纤维素纳米材料的应用开辟了更多的机会。 由于炭渣的碳含量和表面积比原始聚酰亚胺材料更高，因此将其作为增强剂添加到材料中有望改善所得聚酰亚胺复合材料的机械性能。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。
