We are facing unprecedented global challenges around climate change, clean energy, water and sustainability - and these have, at their core, materials solutions. Critical materials for future technologies are often highly complex on multiple length scales, and hence extremely difficult to characterise with a single technique. They commonly involve low atomic weight, mobile elements (e.g. hydrogen, lithium, carbon, sulfur) that are the most challenging to quantitatively characterise in their in-operando state, due to their high rates of diffusion, reactivity and often very low contrast by conventional imaging techniques. Examples of such materials systems include; materials for hydrogen production and storage, battery systems; catalysts to generate new fuels or facilitate decarbonation of industrial processes; interfaces between soft- and hard-matter relevant to hybrid electronics and 'soft' robotics; as well as liquids or liquid- solid interfaces that are critical across the whole engineering and physical sciences research space from geological carbon sequestration, to lubrication in engines, to chemistry and bioengineering.We will create a world-leading cryo-EPS facility to act as a collaborative hub for research that will underpin the UK ambition for a net zero carbon future and a more sustainable society. It will enable the quantitative atomic to micro-scale investigation of light elements that are critical to a host of new technologies associated with a transition to a sustainable, resilient and healthy future society, providing new scientific insights that will drive technological innovation.The equipment will enable the quantitative investigation of light elements across orders of magnitude in length scale - from the micron to the atomic scale, providing an unprecedented opportunity for a step change in our fundamental understanding of these materials structure and chemistry - and ultimately their behaviourThis facility will be based around a cryo hub that will allow samples to be transferred under high vacuum and at cryo conditions between three instruments (i) an atom probe, uniquely positioned to quantitively measure chemical composition of light mobile elements; (ii) a transmission electron microscope with a vacuum-cryo holder and optimised to measure the structure of sensitive samples and also their local bonding environment; (iii) a plasma FIB to allow samples to be prepared for both the atom probe and TEM which have both low contamination and also little damage, and able to perform large-scale 3D imaging. The combination of these instruments will give the UK a powerful characterisation capability that is unique worldwide, putting UK scientists in a leading position to tackle important and urgent global challenges.

我们面临着围绕气候变化，清洁能源，水和可持续性的前所未有的全球挑战 - 这些核心是材料解决方案。未来技术的关键材料在多个长度尺度上通常是高度复杂的，因此用单个技术非常难以表征。它们通常涉及低原子重量，移动元件（例如氢，锂，碳，硫），这些元素由于其高扩散率，反应性的较高速度和经常对常规成像技术的对比度通常非常低。此类材料系统的示例包括：氢生产和存储的材料，电池系统；催化剂产生新的燃料或促进工业过程的脱碳；与混合电子和“软”机器人技术相关的软毛和硬质界面之间的界面； as well as liquids or liquid- solid interfaces that are critical across the whole engineering and physical sciences research space from geological carbon sequestration, to lubrication in engines, to chemistry and bioengineering.We will create a world-leading cryo-EPS facility to act as a collaborative hub for research that will underpin the UK ambition for a net zero carbon future and a more sustainable society.这将使对光元素的微观调查能够对许多新技术至关重要，这些新技术与向可持续，可持续，有弹性和健康的未来社会过渡相关的新技术至关重要我们对这些材料结构和化学的基本理解的改变 - 最终它们的行为将基于一个冷冻枢纽，该枢纽将允许样品在高真空中和在三种仪器之间的冷冻条件下转移样品（i）一个原子探针（i），独特地定位于定量地测量光移动元素的化学化学成分； （ii）带有真空 - 晶体支架的透射电子显微镜，并进行了优化，以测量敏感样品的结构及其局部粘结环境； （iii）一个血浆FIB允许为原子探针和TEM制备样品，这些探针和TEM既有污染，又很少损坏，并且能够执行大规模的3D成像。这些工具的结合将使英国具有强大的特征能力，在全球范围内是独特的，使英国科学家处于应对重要和紧急的全球挑战的领先地位。
