This project aims to develop a revolutionary method for imaging atomic structures. In this method, the image contrast derives from the symmetry of the structure, measured at the picometre scale, using tiny electron probes. This new conceptual approach is expected to overcome some of the key limitations of existing electron microscopy methods by providing increased sensitivity and reduced radiation damage, thereby enabling complex structures in technologically important materials to be determined. This should provide new ways to understand the properties of these materials advanced materials and engineer them for applications in the energy, transport, health, communications and other sectors of society.

该项目旨在开发一种革命性的原子结构成像方法。在这种方法中，图像对比度源自结构的对称性，使用微型电子探针在皮米尺度上测量。这种新的概念方法有望通过提高灵敏度和减少辐射损伤来克服现有电子显微镜方法的一些关键限制，从而能够确定技术上重要的材料中的复杂结构。这应该提供新的方法来了解这些先进材料的特性，并将其设计用于能源、运输、健康、通信和社会其他部门的应用。
