Materials Research Laboratory

宾夕法尼亚大学的材料研究实验室(MRL)在四个主要推动领域支持广泛的互动和跨学科材料研究。分子和表面动力学是一项新的努力，涉及化学家和物理学家，他们正在使用超快激光光谱学来研究表面和凝聚相中的动态分子过程。先进聚合物和陶瓷的设计和合成汇集了一群教师，他们的主要兴趣是开发新的合成方法和新材料。对物质的非周期状态的推力涉及表现出准周期性、玻璃状属性、不可通约性或其他无序方面的非传统材料。界面结构和微观力学的研究旨在加深对界面在决定材料力学性能中的作用的基本理解，并日益重视复合材料和薄膜。此外，一项关于超薄膜的新倡议使用先进的表面科学技术来研究超薄材料中原子突变界面的几何、电子和振动结构。MRL还支持主要中央材料研究设施的开发、运营和维护，并为与其整体计划相关的新教师和高风险研究提供种子资金。该项目目前涉及43名教职员工、12名博士后助理研究员、12名其他技术和科学专业人员、45名研究生和7名本科生。宾夕法尼亚大学MRL由格雷戈里·C·法林顿教授领导。

The Materials Research Laboratory (MRL) at the University of Pennsylvania supports a broad range of interactive and inter- disciplinary materials research in four primary thrust areas. The thrust on molecular and surface dynamics is a new effort involving chemists and physicists who are employing ultrafast laser spectroscopy to study dynamic molecular processes at surfaces and in condensed phases. Design and synthesis of advanced polymers and ceramics brings together a group of faculty whose principal interest is the development of new synthetic methods and new materials. The thrust on non-periodic states of matter addresses unconventional materials that exhibit quasi- periodicity, glass-like properties, incommensurability or other aspects of disorder. The research on structure and micro- mechanics of interfaces aims to develop a fundamental understanding of the role of interfaces in determining the mechanical properties of materials, with increasing emphasis on composite materials and thin films. In addition, a new initiative on ultra-thin films uses advanced surface science techniques to study the geometric, electronic and vibrational structure of atomically abrupt interfaces in ultra-thin materials. The MRL also supports the development, operation and maintenance of major central materials research facilities, and provides seed funds for new faculty and high-risk research related to its overall program. The program currently involves 43 faculty members, 12 postdoctoral research associates, 12 other technical and scientific professionals, 45 graduate students and 7 undergraduates. The University of Pennsylvania MRL is under the direction of Professor Gregory C. Farrington.
