Evolution of nanoporosity in dealloying
Jonah Erlebacher,Jonah Erlebacher,Michael J. Aziz,Alain Karma,Nikolay Dimitrov,Karl Sieradzki +5 more
TL;DR: It is demonstrated that nanoporosity in metals is due to an intrinsic dynamical pattern formation process, and that chemically tailored nanoporous gold made by dealloying Ag-Au should be suitable for sensor applications, particularly in a biomaterials context.
