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.

固体/液体界面在各种物理现象中起着基本作用，例如在催化，晶体生长和许多控制人体建立和大脑功能的生物反应中。因此，在固体/液体界面处阐明原子结构仍然是当今表面科学面临的主要挑战之一，因为它只有了解模型系统中的物理过程，我们可以推断出更复杂的环境。由于界面的埋藏性质，大多数标准的表面科学技术无法访问，这些技术采用强烈吸附的电子探针来获得表面敏感性。界面的研究仅限于采用穿透辐射的技术，例如X射线和中子散射以及光谱法或成像技术，在该技术中，探针与固体表面近距离接近。这些相对较新的技术的开发为固体/液体界面的新研究提供了主要的方法论驱动力。这与同步辐射中的进步相似，在该辐射中，第三代光源目前正在世界各地运行。该提案旨在加强利物浦大学，阿根纳国家实验室和欧洲同步加速器辐射设施的科学家之间的合作。该合作将涉及设备，材料和专业知识的共享以及博士生在使用最先进的实验设备方面的培训。它还将涉及同步辐射技术的使用和开发，以探测固定液体界面处的原子结构。
