Detecting non stationarity in nanoscale systems involves advanced analytical methods and statistical tools:
1. Time-Series Analysis: Techniques like Fourier Transform and wavelet analysis can be used to study time-dependent changes in nanomaterial properties. 2. Spectroscopy: Various spectroscopic techniques, such as Raman and UV-Vis spectroscopy, help monitor changes in electronic and vibrational states. 3. Microscopy: High-resolution electron microscopy can provide insights into structural changes at the nanoscale over time.
