2025_Co3O4_EIS-SXRD

The project's subfolders contain the raw data and plots of the impedance fits with the model comprising three time constants together with the correlation matrices. The fitting results for all models (comprising one, two, and three time constants) are located in this project folder together with the scripts processing the raw data. The data in the subproject folder containing '(sXRD)' were acquired during synchrotron XRD measurements in an operando cell. Please see the experimental part for further details.
Take a look at subprojects:
