This award from the Major Research Instrumentation (MRI) program and the Office of Multidisciplinary Activity of the Directorate for Mathematical and Physical Sciences enables Tuskegee University (TU) to acquire a state-of-the-art Hysitron TI-980 Triboindenter to strengthen its research capability in the emerging areas of nanobio, self-healing materials and other structural and multifunctional materials. Particularly, the instrument will improve TU's research support infrastructure by giving TU a unique set of resources to pursue funding in the micro/nanomechanical aspects of material behavior. The instrument will be used by faculty and students at TU and those at collaborating partners, thereby encouraging synergistic research collaborations. In addition, a collection of course related projects and experiments will be made available to undergraduate and graduate students. Also, the addition of this facility will assist TU faculty in developing new proposals that will not only help understand the fundamental science of materials, but will also help TU to produce a talented and well qualified pool of African-American graduates with the necessary training to compete in a market for high technology applications. It is also anticipated that the fundamental studies delineated in this proposal will eventually result in advancing the nanobio materials applications in aerospace, automobile, biomedical and pharmaceutical areas. Results generated through these research projects will be disseminated through journal and conference publications for the benefit of the scientific community. Tuskegee University (TU) has, over the years with support from National Science Foundation (NSF) and other federal agencies, developed a program of research and education in Materials Science and Engineering (MSE), which is not only very comprehensive but also very effective in recruiting, motivating, mentoring and graduating students with advanced degrees in MSE. The program has produced the largest number minority PhDs in MSE of which over 50 percent are female. Bulk properties of multiphase composite materials (nanoparticles, polymers, fibers) largely depend on the response on how individual phases perform and the load transfer at the interface of these phases which is of a length scale of less than 5 micrometers. Moreover, the structural scale of materials such as polymers, films, bone scaffolds, skin tissue etc. is in nanometers. Also, the polymer properties are highly time- temperature-frequency sensitive due to its inherent viscoelastic nature, and its performance varies significantly at small length scales. Therefore, nanoscale characterization of these materials is extremely critical in understanding the fundamental behavior. Automated state-of-the-art TI-980 TriboNanoindentation equipment is suited for characterizing properties at nano/micro scale due to its high spatial resolution and throughput. The specific studies that will be carried out using the proposed automated nanoindenter include: Biobased resin polymeric nanocomposites as a scaffold material for bone tissue engineering applications, Nanomechanics of skin in the transdermal delivery proteins and vaccines after microneedle treatment, Polymer nanocomposites for structural applications, Self-healing of composites using microcapsule bleeding concept, and Probing the interfacial adhesion of perovskite solar cells. To accomplish these broad range of research activities, the tribonanoindenter system is equipped with modules for dynamic mechanical analysis; extended travel stage and optical microscope with color camera; high load transducer; nanoscale electromechanical characterization; high-resolution mechanical property mapping; high-temperature stage, and ultra-low force mechanical characterization. This state-of-the art all-in-one equipment will serve as an excellent tool in developing science and technology of nanobio materials, while enhancing the research and education capabilities at Tuskegee University (TU).

该奖项获得了主要研究仪器（MRI）计划和数学和物理科学局多学科活动的办公室，这使Tuskegee University（TU）能够获得最先进的Hysitron Ti-980 TriboIndenter，从而增强了Nanobio，自我自我建立材料和其他材料和其他材料的研究能力。特别是，该工具将通过为TU提供一套独特的资源来追求物质行为的微/纳米力学方面的资金来改善TU的研究支持基础设施。 TU的教职员工和合作伙伴的学生将使用该乐器，从而鼓励协同研究合作。此外，本科生和研究生将提供与课程相关的项目和实验的集合。此外，增加此设施将有助于TU教师制定新的建议，这些建议不仅将有助于了解材料的基本科学，而且还将帮助TU生产有必要的非裔美国人毕业生库，并进行必要的培训，并在市场上竞争高科技应用。还可以预料，在该提案中描述的基本研究最终将导致在航空航天，汽车，生物医学和药物区域中推进纳米比奥材料的应用。通过这些研究项目产生的结果将通过期刊和会议出版物传播，以使科学界受益。多年来，Tuskegee University（TU）在国家科学基金会（NSF）和其他联邦机构的支持下，开发了一项材料科学与工程研究和教育计划，该计划不仅非常全面，而且在MSE招募，激励，指导和毕业的学生方面非常有效。该计划在MSE中产生了最多的少数族裔博士学位，其中50％以上是女性。多相复合材料（纳米颗粒，聚合物，纤维）的整体性质在很大程度上取决于对单个相的性能的响应以及这些相的界面的负载转移，该界面的长度比例小于5微米。此外，纳米中的材料（例如聚合物，膜，骨架，皮肤组织等）等材料的结构尺度。同样，由于其固有的粘弹性性质，聚合物的性能是高度温度频率敏感的，并且其性能在较小的长度尺度下差异很大。因此，这些材料的纳米级表征对于理解基本行为至关重要。自动化的最新TI-980 TribonAnoDententation设备适用于由于其高空间分辨率和吞吐量而在纳米/微型尺度上表征性质。将使用拟议的自动纳米插入器进行的具体研究包括：生物基本聚合物纳米复合材料作为骨骼组织工程应用的脚手架材料，在经过微粉制成的概念和组合形成的概念概念的骨骼组织工程应用中，皮肤中皮肤的纳米力学，用于构图的概念，用于构图，用于组合的概念，并将其组合成概念。钙钛矿太阳能电池的界面粘附。为了完成这些广泛的研究活动，TribonAnoindenter系统配备了用于动态机械分析的模块。带有彩色相机的扩展旅行阶段和光学显微镜；高负载传感器；纳米级机电表征；高分辨率机械性能映射；高温阶段和超低力机械表征。这项最先进的设备将是开发纳米比奥材料科学和技术的绝佳工具，同时增强了Tuskegee University（TU）的研究和教育能力。
