The current understanding of the mechanism of the how oil binds to rock such as in enhanced oil recovery hinges on the charged nature of mineral surfaces, particularly clays. Importantly many experimental methods to investigate these surfaces cannot be used with small mineral samples typically available. This project aims to prepare large area substrates with the key surface charge chemistry which should open up these systems to a battery of experimental methods such as SFG and neutron reflection.

目前对石油如何与岩石结合的机理的理解，例如在提高石油采收率方面，取决于矿物表面，特别是粘土的带电性质。重要的是，许多研究这些表面的实验方法不能用于通常可用的小矿物样品。该项目旨在制备具有关键表面电荷化学的大面积衬底，这将为这些系统提供一系列实验方法，如SFG和中子反射。
