Cover: The efficiency of corrosion inhibition by self assembled molecular (SAM) layers can be demonstrated by different techniques. On the cover page metal surfaces with nanofilms are presented by atomic force microscopy. In the presence of aqueous electrolyte solutions AFM images show the change in the surface morphology. In spite of short SAM layer formation time (30 min) by undecenyl phosphonic acid, after immersion into electrolytes, 2D and 3D AFM images proved the efficacy of nanolayer against general but not pitting corrosion. The smooth carbon steel surface covered by SAM layer does not show significant change after immersion into neutral, oxygen containing electrolyte, but the chloride ions deteriorated the surface by deep pits.
