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).

来自主要研究仪器（MRI）计划和数学和物理科学理事会多学科活动办公室的这一奖项使塔斯基吉大学（TU）能够获得最先进的Hysitron TI-980 Triboindenter，以加强其在纳米生物，自我修复材料和其他结构和多功能材料新兴领域的研究能力。特别是，该仪器将通过为TU提供一套独特的资源来改善TU的研究支持基础设施，以寻求材料行为的微观/纳米力学方面的资金。该仪器将由TU的教师和学生以及合作伙伴使用，从而鼓励协同研究合作。此外，课程相关的项目和实验的集合将提供给本科生和研究生。此外，该设施的增加将有助于TU教师制定新的建议，这不仅有助于了解材料的基础科学，而且还将帮助TU产生一个有才华的和合格的非洲裔美国毕业生池，并接受必要的培训，以在高科技应用市场上竞争。预计该提案中描述的基础研究最终将推动纳米生物材料在航空航天，汽车，生物医学和制药领域的应用。通过这些研究项目产生的成果将通过期刊和会议出版物传播，以造福科学界。塔斯基吉大学（TU）多年来在国家科学基金会（NSF）和其他联邦机构的支持下，开发了材料科学与工程（MSE）的研究和教育计划，该计划不仅非常全面，而且在招聘，激励，指导和毕业具有MSE高级学位的学生方面非常有效。该方案培养了最多的少数民族博士，其中50%以上是女性。多相复合材料（纳米颗粒、聚合物、纤维）的整体性能在很大程度上取决于对各个相如何表现的响应以及这些相的界面处的载荷传递，这些相的界面具有小于5微米的长度尺度。此外，诸如聚合物、薄膜、骨支架、皮肤组织等材料的结构尺度是纳米级的。此外，聚合物性质由于其固有的粘弹性性质而对时间-温度-频率高度敏感，并且其性能在小的长度尺度上显著变化。因此，这些材料的纳米级表征对于理解基本行为至关重要。自动化的最先进的TI-980 TriboNanoindentation设备由于其高空间分辨率和吞吐量，适合表征纳米/微米尺度的特性。将使用所提出的自动纳米压痕仪进行的具体研究包括：生物基树脂聚合物纳米复合材料作为骨组织工程应用的支架材料，微针处理后经皮递送蛋白质和疫苗的皮肤纳米力学，用于结构应用的聚合物纳米复合材料，使用微胶囊出血概念的复合材料自愈合，以及探测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系统配备了动态力学分析模块;扩展行程阶段和光学显微镜与彩色相机;高负载传感器;纳米机电表征;高分辨率机械性能映射;高温阶段，和超低力机械表征。这种最先进的一体化设备将成为开发纳米生物材料科学和技术的绝佳工具，同时增强塔斯基吉大学（TU）的研究和教育能力。
