Dynamics of Lateral Processes at the Air/Water Interface

在分析和表面化学计划的支持下，Majda教授和他在加州大学伯克利分校的同事正在进行空气/水界面侧质量和质子传输的研究。 这些研究使用Majda教授开发的电化学飞行时间方法，该方法用于模拟两亲膜。 在这些研究中获得的信息在空气/水界面的分子的横向扩散，在界面处的水的动态结构，和在空气/脂质/水界面的质子扩散。 这些界面转运过程是涉及膜能量转换和储存的基本生物学过程，本研究项目提供了有关这些过程的重要基础信息。利用电化学瞬态方法，获得了空气/水界面上分子和质子的横向扩散信息。 利用Langmuir单分子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许多材料科学应用中也是令人感兴趣的，例如电池和燃料电池技术。

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.
