Nanoplasmonic sensing and QCM-D as ultrasensitive complementary techniques for kinetic corrosion studies of aluminum nanoparticles

► QCM-D and nanoplasmonic sensing enable submonolayer, in situ, real-time sensing of Al corrosion. ► Nanoplasmonic sensing results can be quantized by correlation to model calculations. ► Oxidation of Al nanodisks proceeds by two mechanisms: (i) growth of a homogeneous oxide layer, (ii) fragmentation and roughening.
