In-operando techniques for early-stage corrosion
… native state. We have, therefore, developed in-operando measurement methods. Several complementary approaches were developed: confocal fluorescence microscopy, synchrotron X-ray absorption and diffraction, and electron microscopy. These techniques address various aspects of the corrosion process …
