The cover picture shows a force microscope image of a MoO 3 nanocrystal resting on the surface of a MoS 2 single crystal. The chemical formula of the nanocrystal was highlighted by writing “MoO 3 ” on its surface after its components, Mo and O, were identified by atomic resolution imaging. The desired pattern was engraved with a force microscope tip by scanning across the surface with an applied load that exceeded the critical force required to break bonds between atoms as the nanocrystal was plastically deformed. After this “nanomachining”, the resulting changes to the MoO 3 nanocrystal were studied nondestructively using the same force microscope tip operating at a much lower load. The ability to manipulate and study the properties of materials on the atomic to nanometer scales is discussed by C. M. Lieber et al. on pp. 686
