Stainless Silver

A photograph of EECS Professor L. Jay Guo holding a stainless silver layer.

L. Jay Guo, EECS Professor, shows a "stainless" silver layer that his research group has created in the Engineering Research Building II on North Campus of the University of Michigan in Ann Arbor, MI on February 21, 2017. By throwing aluminum in with the silver, Guo's research team has created the thinnest stable silver layer ever seen. The aluminum guards the silver against its well known problem: tarnishing, and also keeps the silver bonded to a glass surface and other oxide type materials.
