ARI: Acquisition of Scanning Acoustic Microscope

9601582 Dzenis这是一个学术研究基础设施奖，为购买通用扫描声学显微镜（SAM）提供资金。SAM将微成像、微检测和显微非破坏性评估设备结合在一个仪器中。它将致力于支持内布拉斯加大学林肯分校的科学和工程研究和教育。获得SAM将有利于大量当前和计划中的研究项目，这些项目涵盖广泛的主题，例如，新聚合物、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、玻璃化转变和结晶特性的研究；电火花加工和静电纺丝新兴制造技术研究先进非均相材料及复合材料微损伤演化研究界面微脱粘研究表面形貌及亚表面残余应力研究；研究导致智能无损评估系统的发展，以及其他。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名教员的参与证明了该仪器的多学科性质。除了广泛的研究应用之外，所获得的系统还将在几个高级本科和研究生课程中用作实验室设备。这些课程包括固体实验力学、晶体学、实验复合材料、损伤力学、薄膜、表面处理、机械加工等。新系统的用户友好的计算机控制和数据采集软件将使学生专注于材料的机械行为和微观结构的特点。获得这种先进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将使内布拉斯加大学林肯分校在研究领域处于领先地位，在这些领域可以利用该技术的独特功能。这些特征包括广泛的分辨率和穿透深度，三维微成像，微尺度无损评估，以及材料的几何形态和机械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到UNL，并将提高他们的实验研究培训的质量。收购SAM也符合当地先进和新型材料行业的利益，如Brunswick Composites、Telex、Addax、Spirotech、Cushman等。SAM服务目前在内布拉斯加州不可用。＊＊＊

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. ***
