I found this paper, Real-Time Monitoring of Atmospheric Magnesium Alloy Corrosion, fascinating and truly innovative. Sanna Virtanen describes a method to make sensitive real-time measurements of the atmospheric corrosion of Mg.
This paper is also the first in the new focus issue on advanced experimental methods honoring Hugh Isaacs. As such, like the other papers that will appear in that issue, it is open access. Note that submissions to this focus issue are still open.
