This project aims to tackle a great challenge of atomic-scale characterisation: quantitative structure determination. Powerful new electron microscopes offer a window into the atomic world, but complex electron multiple scattering has limited reliable structure determination to ultrathin materials. This project expects to overcome this barrier. Anticipated outcomes include methods that use the latest detector technology to determine structure and interatomic bonding in much thicker nanostructures than hitherto possible. This should benefit academic and industrial researchers by giving them new tools to understand and design high-performance materials for applications ranging from catalysis to energy storage to next-generation electronics.

该项目旨在解决原子尺度表征的巨大挑战：定量结构测定。功能强大的新型电子显微镜提供了一个进入原子世界的窗口，但复杂的电子多重散射限制了对材料的可靠结构测定。该项目有望克服这一障碍。预期的成果包括使用最新的探测器技术来确定比迄今为止可能的更厚的纳米结构中的结构和原子间键合的方法。这将使学术和工业研究人员受益，为他们提供新的工具来理解和设计高性能材料，用于从催化到储能到下一代电子产品的应用。
