项目摘要

The solid/liquid interface plays a fundamental role in a diverse range of physical phenomena, for example in catalysis, crystal growth and in many biological reactions that govern the building of the human body and the functioning of the brain. Unravelling the atomic structure at the solid/liquid interface remains, therefore, one of the major challenges facing surface science today for it is only by understanding the physical processes in model systems that we can extrapolate to more complex environments. Due to the buried nature of the interface, it is inaccessible to most standard surface science techniques that employ strongly adsorbed electron probes to gain surface sensitivity. Study of the interface is restricted to techniques that employ penetrating radiation, such as x-ray and neutron scattering and optical spectroscopy, or imaging techniques, where the probe is brought in close proximity to the solid surface. Development of these relatively new techniques is providing the main methodological driving force for new investigations of the solid/liquid interface. This has been paralleled by the advancements made in synchrotron radiation, where a third generation of light sources is currently operational around the world. This proposal aims to strengthen the collaboration between scientists at the University of Liverpool, Argonne National Laboratory and the European Synchrotron Radiation Facility in the study of this complex interface. The collaboration will involve the sharing of equipment, materials and expertise and the training of PhD students in the use of state-of-the-art experimental equipment. It will also involve the use and development of synchrotron radiation techniques for probing the atomic structure at the solid-liquid interface.

固/液界面在各种物理现象中发挥着重要作用，例如催化，晶体生长和许多生物反应，这些反应控制着人体的构建和大脑的功能。因此，解开固/液界面的原子结构仍然是当今表面科学面临的主要挑战之一，因为只有通过理解模型系统中的物理过程，我们才能推断出更复杂的环境。由于界面的掩埋性质，大多数标准的表面科学技术都无法使用强吸附电子探针来获得表面灵敏度。对界面的研究仅限于采用穿透辐射的技术，如X射线和中子散射和光谱学，或成像技术，其中探针被带到非常接近固体表面。这些相对较新的技术的发展提供了主要的方法驱动力的新的调查固/液界面。同步辐射技术的进步已经证明了这一点，第三代光源目前正在世界各地运行。这一提议旨在加强利物浦大学、阿贡国家实验室和欧洲同步辐射设施的科学家在研究这一复杂界面方面的合作。合作将包括分享设备、材料和专门知识，以及培训博士生使用最先进的实验设备。它还将涉及同步辐射技术的使用和发展，用于探测固液界面的原子结构。
