Anomalous Decay of Electronically Stabilized Lead Mesas on Ni(111)\ud [PDF]
, 2011 With their low surface free energy, lead films tend to wet surfaces. However, quantum size effects (QSE) often lead to islands with distinct preferred heights. We study thin lead films on Ni(111) using low energy electron microscopy and selected area low

Effect of trace elements on the interface reactions between two lead-free solders and copper or nickel substrates [PDF]
Journal of Mining and Metallurgy. Section B: Metallurgy, 2007 Traditional Sn-Pb solder alloys are being replaced, because of environmental and health concerns about lead toxicity. Among some alternative alloy systems, the Sn-Zn and Sn-Cu base alloy systems have been studied and reveal promising properties.
