This work will pioneer a new form of microscopy that will integrate quantum microscopy based on diamond sensors within experimental platforms used in electron microscopy providing unique contrast to correlate nanoscale structure and chemical composition with magnetic, oxidation and electronic states of matter with unprecedented detail. This will be achieved by integrating two local probes, namely Nitrogen Vacancy spin active defects in diamond and an electron beam to map functional and structural features of the same unique nanostructure or single molecule. Chemical reactions promoted by and simultaneously imaged by electron beams will also be imaged in situ enabling accurate predictions of bond dissociation events and control of chemical reactions.The QUERY project will lay the foundation for implementation of an integrated quantum and electron microscopy measurement platform for in situ studies. This unique measurement tool will tackle characterisation challenges at the frontier of materials science, opening the door for rational design of complex materials and enable the targeted design of quantum, spintronic, magnetic, and electronic materials and devices. Time-resolved measurements utilising QUERY will enable the study of chemical reactions at the single-molecule level, and discovery new ways of breaking and making chemical bonds. Ultimately this work will facilitate the application of next generation materials to advance the UK's global position in areas of enormous technical importance including power conversion, energy storage, clean catalysis, data storage, microelectronics and drug development.

这项工作将开创一种新的显微镜形式，将基于钻石传感器的量子显微镜集成到用于电子显微镜的实验平台中，以前所未有的细节提供独特的对比，将纳米结构和化学成分与物质的磁性、氧化和电子状态相关联。这将通过集成两个局部探针，即钻石中的氮空位自旋活性缺陷和电子束来实现，以绘制相同独特纳米结构或单个分子的功能和结构特征。由电子束促进并同时成像的化学反应也将被原位成像，从而能够准确地预测键解离事件和控制化学反应。该查询项目将为实施用于现场研究的综合量子和电子显微镜测量平台奠定基础。这一独特的测量工具将解决材料科学前沿的表征挑战，为合理设计复杂材料打开大门，并使量子、自旋电子、磁性和电子材料和设备能够进行有针对性的设计。利用QUERY的时间分辨测量将使在单分子水平上研究化学反应成为可能，并发现打破和建立化学键的新方法。最终，这项工作将促进下一代材料的应用，以提升英国在具有巨大技术重要性的领域的全球地位，包括电力转换、能量储存、清洁催化、数据存储、微电子和药物开发。
