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

小行星9314426 这个为期两年的奖项支持美国-法国表面科学合作研究，大卫L。宾夕法尼亚州立大学的阿拉拉和法国巴黎居里研究所的弗朗西斯朗德勒兹。 他们的研究目的是调查分子结构之间的定量相关性在单层组装的烷基硅氧烷膜和条件制备这些膜。 相关性将被用来确定薄膜的性能，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;基板/薄膜结合在薄膜排序中的作用;以及水在薄膜形成中的作用。 美国研究人员为这项合作带来了有机薄膜及其结构分子表征方面的大量专业知识。 这是补充法国技能的合成和表征的单层膜。 发展具有最小缺陷的稳定分子膜是最终目标。 这些进展对物理、化学、生物和材料科学等学科的科学和技术应用非常重要。 半导体、纳米光刻和光电子器件是将从分子膜结构的改进中受益的领先技术。 ***

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. ***
