ARI: Acquisition of Scanning Acoustic Microscope

9601582泽尼斯这是一个学术研究基础设施奖，提供资金购买通用扫描声学显微镜。SAM在一台仪器中结合了显微成像、显微测试和显微无损评估设备。它将致力于支持内布拉斯加州大学林肯分校的科学和工程研究和教育。收购SAM将有助于目前和计划中的大量研究项目，包括新型聚合物、金属、复合材料和涂层的基础研究和开发；聚合物中化学反应、玻璃化转变和结晶的特性研究；电火花加工和电纺丝等新兴制造技术的研究；先进非均质材料和复合材料中微损伤演化的研究；界面微脱粘研究；表面形态和亚表面残余应力研究；导致开发智能无损评估系统的研究等等。来自工程与技术学院、艺术与科学学院和牙科学院七个系的11名教职员工的参与证明了该仪器的多学科性质。除了广泛的研究应用外，所获得的系统还将作为实验室设备用于几个高级本科生和研究生课程。这些课程包括固体实验力学、结晶学、实验复合材料、损伤力学、薄膜、表面精加工、机械加工等课程。新系统界面友好的计算机控制和数据采集软件将使学生能够集中精力研究材料的力学行为和微观结构的特点。购买这种尖端设备将改善国家研究和教育基础设施。目前，世界上只有少数几所顶尖大学的实验室里有这项新技术。因此，收购SAM将使内布拉斯加-林肯大学在可以利用这项技术的独特功能的研究领域处于领先地位。这些功能包括广泛的分辨率和渗透深度、三维显微成像、微尺度无损评估，以及关于材料几何形态和力学性能分布的综合信息。新的实验能力将有助于吸引高质量的研究人员和学生来联合国学习，并将提高他们实验研究培训的质量。收购SAM也符合当地涉及先进和新颖材料的行业的利益，如Brunswick Composites、Telex、Addax、Spirotech、Cushman等。内布拉斯加州目前无法提供SAM服务。***

9601582 Dzenis This is an Academic Research Infrastructure Award that provides funds to purchase a Universal Scanning Acoustic Microscope (SAM). The SAM combines microimaging, microtesting, and microscopic non-destructive evaluation devices in a single instrument. It will be dedicated to support research and education in science and engineering at the University of Nebraska-Lincoln. Acquisition of SAM will be beneficial for a large number of current and planned research projects spanning a wide range of topics including, for example, fundamental studies and development of new polymers, metals, composites, and coatings; studies of peculiarities of chemical reactions, glass transitions, and crystallization in polymers; studies on emerging manufacturing technologies of electrical discharge machining and electrospinning; studies of evolution of microdamage in advanced heterogeneous materials and composites; studies of microdebonding at interfaces; studies on surface morphology and subsurface residual stresses; studies leading to development of smart nondestructive evaluation system, and others. The multidisciplinary nature of the instrument is evidenced by the involvement of eleven faculty members from seven Departments in the Colleges of Engineering and Technology, Arts and Sciences, and Dentistry. In addition to the broad research applications, the acquired system also will be used as a laboratory device in several senior undergraduate and graduate courses. These include courses on experimental mechanics of solids, crystallog raphy, experimental composites, damage mechanics, thin films, surface finishing, machining, and others. The user friendly computerized control and data acquisition software of the new system will allow students to concentrate on the peculiarities of mechanical behavior and microstructure of materials. Acquisition of this sophisticated equipment will improve national research and education infrastructure. At the present time, only a few of the top universities thro ughout the world have this new technology available in their labs. Thus the acquisition of SAM will place the University of Nebraska-Lincoln in a leading position with regard to the research areas where the unique features of this technique can be utilized. These features include a wide range of resolutions and depths of penetration, three-dimensional microimaging, microscale non-destructive evaluation, and a combined information on geometric morphology and distribution of mechanical properties of materials. New experimental capabilities will assist in attracting quality researchers and students to UNL and will improve the quality of their experimental research training. The acquisition of SAM is also in the interests of local industries involved with advanced and novel materials, such as Brunswick Composites, Telex, Addax, Spirotech, Cushman, and others. SAM service is currently unavailable in Nebraska. ***
