摘要：

(Figure Presented) Close up: The atomic arrangement of industrial-style MoS2 nanocatalysts can be scrutinized by using single-atom-sensitive electron microscopy (see picture). This technique, which provides an excellent agreement between simulation and experiment, allows element detection in compound materials and permits the type and the concentration of the catalytically important edge sites to be estimated. © 2010 Wiley-VCH Verlag GmbH & Co.
