Acquisition of a Scanning Nanoindentation Testing System for Characterization of Bone Materials at the Nanometer Scale

0076497Rho.这个奖项给孟菲斯大学提供了支持的收购扫描纳米压痕测试系统的表征骨材料在纳米压痕尺度。扫描纳米压痕仪，它结合了纳米压痕仪的载荷-位移传感器与原子力显微镜的图像扫描能力，将用于确定骨材料的机械性能和图像表面微观结构和形貌。这将构成我们在更接近细胞水平的尺度上理解骨组织力学能力的重大进步。了解这些机械性能和结构特征是预测整个骨骼行为和确定衰老和疾病过程改变骨骼强度的程度的关键一步。这一新仪器将加强孟菲斯大学的研究基础设施，并将作为将最先进的技术和仪器引入若干工程课程的中心。***

0076497Rho. This award to the University of Memphis provides support for the acquisition of a scanning nanoindentation testing system for the characterization of bone materials at the nanoindentation scale. A scanning nanoindenter, which combines the load-displacement transducer of a nanoindenter with the image scanning capabilities of an atomic force microscope, will be used to determine the mechanical properties and image surface microstructure and topography of bone materials. It will constitute a major advance in our ability to understand bone tissue mechanics on a scale much closer to the cellular level. Knowledge of such mechanical properties and structural characteristics are a key step towards predicting the behavior of whole bone and determining the extent to which aging and disease processes alter the strength of bone. This new instrument will enhance the research infrastructure of the University of Memphis and will also serve as a focal point for the introduction of state-of-the-art techniques and instrumentation into several engineering courses. ***
