9872817PershanThe principal objective of this project is to develop and carry out x-ray scattering experiments that will improve our knowledge of the fundamental properties of the liquid surface and/or which will make use of the liquid surface to model fundamental two dimensional statistical phenomena. Two examples of phenomena to be studied include: (i) The relation between the thermodynamic properties of fluid phases of two dimensional Langmuir monolayers and the short range 2D positional order and (ii) The interfacial compositional structure along the surface normal of wetting layers of complex systems, such as binary liquids and polymer brushes.%%%Until recently there were few experimental methods capable of obtaining fundamental knowledge regarding the microscopic surface structure of liquids. Possible impact of information obtained through this project would be improved procedures for development of liquid based technologies such as lubrication, paints, biomedical, etc. This project will also educate a new generation of x-ray scattering scientists.

这个项目的主要目标是开发和进行x射线散射实验，这些实验将提高我们对液体表面基本性质的了解，和/或将利用液体表面来模拟基本的二维统计现象。需要研究的两个例子包括：(I)二维朗缪尔单分子膜的热力学性质与短程2D位序之间的关系和(Ii)复杂体系(如二元液体和聚合物刷)润湿层表面法线上的界面组成结构。通过该项目获得的信息的可能影响将是改进液体技术的开发程序，如润滑、油漆、生物医学等。该项目还将教育新一代X射线散射科学家。
