Different types of metal cluster will be generated and deposited into suitable supports with a selection of cluster beam sources, including a caesium-sputtering source of small negative cluster ions (Alton source). These deposited clusters will then be imaged down to atomic resolution using TEM (transmission electron microscopy), especially in STEM (scanning transmission electron microscope) mode and their chemical structure probed by XPS (x-ray photoelectron spectroscopy). Ultimately the atomic and chemical structures of the clusters will be correlated with catalytic and/or catalytic growth experiments conducted by or with partner groups, enabling materials optimisation. The clusters studied will include binary nanoalloy systems. The experimental studies will be complemented by theoretical modelling of the clusters in collaboration with the Genoa group (Prof Ferrando). (x-ray o)

不同类型的金属团簇将产生和沉积到合适的支持与选择的集群束源，包括小负团簇离子的铯溅射源（Alton源）。然后，这些沉积的簇将使用TEM（透射电子显微镜）成像至原子分辨率，特别是在STEM（扫描透射电子显微镜）模式下，并且通过XPS（x射线光电子能谱）探测它们的化学结构。最终，簇的原子和化学结构将与由合作小组或与合作小组进行的催化和/或催化生长实验相关联，从而实现材料优化。研究的集群将包括二元纳米合金系统。实验研究将通过与热那亚小组（Ferrando教授）合作的集群理论建模来补充。（X射线O）
