Acquistion of The Nanomechanical Test System for Undergraduate Research and Education

Hysitron TriboScope纳米机械测试仪是一种定量的深度传感纳米压痕和纳米凹槽系统，它与扫描探针显微镜(SPM)接口，提供原位成像。收购TriboScope纳米机械测试系统将使我们能够解决纳米结构部件领域的一些公开问题。其中两个悬而未决的问题包括：(A)生产和制造技术不一致，导致同一纳米系统的结果不同；(B)获得可靠和基本的耐久性和材料特性数据库；以及(C)利用真实材料特性的纳米结构材料的计算建模。将在此测试系统上进行的各种类型的实验将使我们能够直接解决问题(B)和(C)。将进行的测试包括模数、硬度、断裂韧性测量，以及力-位移曲线的产生。纳米结构代表了一个新的科学领域，可以扩大知名材料的尺寸、效率和设计。随着这一领域的发展，产生了更复杂的结构，需要更好的理解和更一致的方法来获得可靠的材料性能。凭借全国最成功的非裔美国男性双学位工程项目，莫尔豪斯学院处于有利地位，通过增加工程和应用物理项目的学生数量和留住学生，对非裔美国人血统的工程师的生产产生重大影响。这种设备不仅将服务于莫尔豪斯学院的本科生，也将服务于邻近的澳大利亚大学的本科生文科学院。该联盟中直接受到这种设备采购影响的大学包括克拉克·亚特兰大大学、莫里斯·布朗学院和斯佩尔曼学院，斯佩尔曼学院是一所私立的文科历史上面向非裔美国女性的黑人学院。来自这些学院的学生不仅可以交叉注册并在邻近的学校上课，还可以完成研究项目。因此，莫尔豪斯学院的研究机会也将对克拉克亚特兰大、莫里斯·布朗和斯佩尔曼学院的学生产生直接影响。

0321106AbstractThe Hysitron TriboScope Nanomechanical test instrument is a quantitativedepth-sensing nanoindentation and nanoscratch system which is interfaced with a scanningprobe microscope (SPM) to provide in-situ imaging. The acquisition of the TriboScope Nanomechanical Test System will enable us toaddress some of the open issues in the field of nanoscale structural components. Two ofthe open problems include (a) the inconsistent production and fabrication techniques whichlead to varied results for the same nanosystem, (b) the procurement of reliable andfundamental data banks of durability and material properties, and c) the computationalmodeling of nanostructured materials which utilize realistic material properties. Thetypes of experiments that will be performed on this test system will allow for us todirectly address issues (b) and (c). The tests that will be performed include Modulus,hardness, fracture toughness measurements, and the generation of force vs. displacementcurves. Nanostructures represent a new field of science that can extend the size, efficiency anddesign of well-known materials. As this field has progressed, more elaborate structureshave been generated that require a better understanding and more consistent methodologyfor obtaining reliable material properties.With the nation's most successful Dual-Degree Engineering program for African-Americanmales, Morehouse College is well positioned to have a significant impact on the productionof engineers of African American lineage by increasing the number and the retention ofstudents in the engineering and applied physics programs. This equipment will not only serveundergraduates at Morehouse College, but will also serve neighboring undergraduate liberalarts colleges in the AUC. Colleges in the consortium directly impacted by the procurementof this equipment include Clark Atlanta University, Morris Brown College, and SpelmanCollege, a private liberal arts Historically Black College for African-American females.Students from these colleges are not only allowed to cross-register and take classes atthe neighboring schools, but may also complete research projects. Therefore, the researchopportunities at Morehouse will also have a direct impact on the students at ClarkAtlanta, Morris Brown and Spelman College.
