Materials Research Laboratory

宾夕法尼亚大学的材料研究实验室（MRL）在四个主要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化学家和物理学家利用超快激光光谱学研究表面和凝聚态动态分子过程的新领域。高级聚合物和陶瓷的设计和合成汇集了一群主要兴趣是开发新合成方法和新材料的教师。对物质非周期状态的研究主要针对那些表现出准周期性、玻璃样性质、不可通约性或其他无序方面的非常规材料。对界面结构和微观力学的研究旨在对界面在决定材料力学性能中的作用有一个基本的认识，并日益重视复合材料和薄膜。此外，超薄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还支持主要中心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员和高风险研究提供种子基金。现有教职工43人，博士后研究员12人，其他科技专业人员12人，研究生45人，本科生7人。宾夕法尼亚大学MRL由Gregory C. Farrington教授指导。

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.
