The front cover artwork is provided by Dr. Peter Spurgeon, Dr. Da‐Jiang Liu, and Prof. Jim Evans at Ames Laboratory USDOE and Iowa State University. The top images show the decay of a 2D Au island on Au(111) in the presence of 24 milli‐monolayers of S. The enhancement of island decay with increasing S coverage is quantified in the lower left image for ∼85 nm2 Au islands. The Au‐S complexes implicated as facile mass carriers enhancing decay are also illustrated. Read the full text of the Article at 10.1002/cphc.202000884.
