9406936 Saam Theoretical research will be done on systems in which the properties of interfaces play a dominant role. Included are studies of fluid dynamics in restricted geometries, directional solidification, droplet spreading, lubrication, polymer adsorption, micelle formation and structure, wetting phenomena in both mixtures of helium-three and -four and of hydrogen and deuterium, wetting in metallic films, the properties of helium-three and -four mixtures in aerogel, and the dynamics of prewetting. Techniques to be employed include Monte Carlo and molecular dynamics simulations of both continuum and lattice models, density-functionals and mean- field theory. %%% A broad research program using analytical and computational techniques will investigate a variety of physical phenomena in which the interfaces between two different phases play an important role. For instance, under what conditions does a fluid wet a surface? The properties of the interface between the solid surface and the fluid largely determines whether the fluid will wet the surface. This can have profound fundamental and technological implications. ***

9406936 SAAM理论研究将对界面的性质起主要作用的系统进行。 包括在受限的几何形状，方向固化，液滴扩散，润滑，聚合物吸附，胶束形成和结构中的流体动力学研究，氦和氢和氢的混合物中的润湿现象，在金属膜中润湿，润湿现象气凝胶中氦三和四种混合物的特性以及预锻力的动力学。 要使用的技术包括连续和晶格模型的蒙特卡洛和分子动力学模拟，密度功能和均值理论。 %% %%使用分析和计算技术进行广泛的研究计划将研究各种物理现象，其中两个不同阶段之间的接口起着重要作用。 例如，在什么条件下流体湿润表面？ 固体表面和流体之间界面的性质在很大程度上决定了流体是否会湿润表面。 这可以具有深远的基本和技术意义。 ***
