Dynamics of Lateral Processes at the Air/Water Interface

在分析和表面化学项目的支持下，加州大学伯克利分校的Majda教授和他的同事们正在进行空气/水界面侧质量和质子输运的研究。这些研究使用了由Majda教授开发的电化学飞行时间方法，该方法用于模拟两亲性膜。这些研究获得了分子在空气/水界面上的横向扩散、界面上水的动态结构和质子在空气/脂质/水界面上的扩散的信息。这些界面传递过程是参与膜能量转导和储存的基本生物过程，本研究为这些过程提供了重要的基础信息。本研究利用电化学瞬态方法，获得了分子和质子在空气/水界面上的横向扩散信息。利用朗缪尔单层膜作为生物膜的模型，在这些研究中获得了详细的二维扩散信息。质子输运信息和扩散常数在电池和燃料电池技术等许多材料科学应用中也引起了人们的兴趣。

With the support of the Analytical and Surface Chemistry Program, Professor Majda and his coworkers at the University of California-Berkeley are carrying out studies of lateral mass and proton transport at the air/water interface. These studies use electrochemical time-of-flight methods developed by Professor Majda, which are applied to model amphiphilic membranes. Information about the lateral diffusion of molecules at the air/water interface, the dynamic structure of water at the interface, and proton diffusion at the air/lipid/water interface is obtained in these studies. These interfacial transport processes are fundamental biological processes involved in membrane energy transduction and storage, and this research project provides important fundamental information about these processes. Using electrochemical transient methods, information about the lateral diffusion of molecules and protons at the air/water interface is obtained in this research project. Using Langmuir monolayers as models of biomembranes, detailed two-dimensional diffusion information is obtained in these studies. Proton transport information and diffusion constants are also of interest in many materials science applications such as battery and fuel cell technology.
