U.S.-France Cooperative Research: Defects in Grafted Molecular Films

9314426 Allara这个为期两年的奖项支持宾夕法尼亚州立大学的David L.Allara和法国巴黎居里研究所的Francis Rondelez在表面科学方面的美法合作研究。他们的研究目的是调查烷基硅氧烷薄膜单层组装中的分子结构与制备这些薄膜的条件之间的定量相关性。相关关系将被用来确定薄膜的性质，特别是表面润湿。宾夕法尼亚州立大学和居里研究所的平行独立实验旨在确定薄膜制备的温度；基片/薄膜结合在薄膜有序中的作用；以及水在薄膜形成中的作用。这位美国研究人员为这项合作带来了有机薄膜及其结构的分子结构表征方面的丰富专业知识。这与法国在单层膜的合成和表征方面的技能相辅相成。开发稳定的、缺陷最少的分子膜是最终的目标。这些进展对跨越物理、化学、生物和材料科学等学科的科学和技术应用具有重要意义。半导体、纳米级光刻和光电子器件是将受益于分子膜结构改进的领先技术。***

9314426 Allara This two-year award supports U.S.-France cooperative research in surface science between David L. Allara of Pennsylvania State University and Francis Rondelez of the Institut Curie, Paris, France. The objective of their research is to investigate the quantitative correlations between molecular structures in monolayer assemblies of alkysiloxane films and conditions for preparation of these films. The correlations will be used to determine film properties, in particular, surface wetting. Parallel, independent experiments at Penn State and the Institut Curie are aimed at determining the temperature for film preparation; the role of substrate/film bonding in film ordering; and the role of water in film formation. The U.S. investigator brings to this collaboration considerable expertise in organic thin films and molecular characterization of their structure. This is complemented by French skills in synthesis and characterization of monolayer films. Development of stable molecular films with minimal defects is the ultimate goal. Such advances are important to scientific and technological applications cutting across the disciplines of physics, chemistry, biology and materials science. Semiconductors, nanoscale lithography and optoelectronic devices are among the leading technologies that would benefit from improvements in structure of molecular films. ***
