小行星9802290 这是一个小组研究计划，涉及两名物理学家和一名工程师。该项目将研究在固体、润湿液体和气相相遇的三相接触线附近的微观区域发生的现象。 在复杂或多组分流体中，定性地已知接触线附近和薄膜中的组分的相对浓度和自组装不同于远离接触线的本体或界面上的那些。 然而，关于发生了什么的定量信息很少。 光学的， X射线、中子和原子力 研究人员将研究这些薄膜和自组装体的独特微观结构，并探索它们如何控制宏观润湿现象。该项目将把高温、金属系统的研究与室温、水和有机系统的研究结合起来。这项研究将提高对流体在密闭环境中如何行为的理解，并将普遍提高我们对流体如何润湿和流过表面的知识。 该项目的多学科性质为研究生提供了良好的培训，为他们在一系列技术领域的职业生涯做好准备。这项研究是基础性的，但它在许多领域的技术应用，如印刷和机械，是直接和非常重要的。 这是一个小组研究计划，涉及两名物理学家和一名工程师。研究的重点是流体如何润湿和在表面上流动。 这是一个具有根本重要性的复杂问题。它在润滑、清洁剂等领域也具有很大的技术重要性。研究小组将使用超高真空， 光学的， X射线、中子和原子力 研究人员将研究这些薄膜和自组装体的独特微观结构，并探索它们如何控制宏观润湿现象。该项目将把高温、金属系统的研究与室温、水和有机系统的研究结合起来。 该项目的多学科性质为研究生提供了良好的培训，为他们在一系列技术领域的职业生涯做好准备。 这项研究是基础性的，但它在许多领域的技术应用，如印刷和机械，是直接和非常重要的。 ***

9802290 Garoff This is small group research proposal involving in two physicists and an engineer. The project will investigate phenomena occurring in the microscopic region near the three-phase contact line where a solid, a wetting liquid and the vapor phase meet. In complex or multi- component fluids, it is qualitatively known that the relative concentration and self-assembly of the components near the contact line and in the thin film differ from those in the bulk or on the interface far from the contact line. However, there is scant quantitative information about what is going on. Using ultrahigh vacuum, optical, x-ray, neutron and atomic force microscopy techniques the researchers will investigate the unique microscopic structures of these films and self-assemblies, and probe how they control macroscopic wetting phenomena. The project will integrate studies of high temperature, metallic systems with studies of room temperature, aqueous and organic systems. The research will improve the understanding of how fluids behave in confined environments and will generally improve our knowledge of how fluids wet and flow over surfaces. The multidisciplinary character of the project provides excellent training for graduate students, preparing them for careers in a range of technical areas. The research is fundamental, but its application to technology in many areas, such as printing and mechanics, is immediate and of high importance. %%% This is small group research proposal involving in two physicists and an engineer.
