Atomic Force and Scanning Tunneling Microscopes

在巴黎圣母院获得了补充现有扫描隧道显微镜（STM）设施的额外设备。新仪器是原子力显微镜（AFM）和STM，设计用于在超高真空（UHV）条件下工作。这两种仪器都将使用现有的控制/分析系统。这些仪器将用于将催化活性与模型支持催化剂和铂单晶的尺寸和晶体相等结构和形态特征联系起来。新仪器将允许在原子尺度上观察结构和形态。

Additional equipment to supplement the existing scanning tunnelling microscope (STM) facilities at Notre Dame is acquired. The new instruments are an atomic force microscope (AFM) and a STM designed for operation under ultrahigh vacuum (UHV) conditions. Both instruments will use the existing control/analysis system. The instruments will be used to correlate catalytic activity with structural and morphological features such as size and crystal phases in model supported catalysts and platinum single crystals. The new instruments will permit the observation of structure and morphology at atomic scale.
