Porous materials play an important role in several fields of technology, especially for energy applications like photovoltaics, electrolysis or batteries. The activity of porous films is affected by properties like porosity, film thickness, chemical composition of the material as well as the crystallinity of the framework. The complex morphology of such porous films constitutes a challenge even for modern analytical techniques and requires new approaches employing the combination/complementation of data of different analytical methods. In this contribution we characterize thin mesoporous iridium-titanium mixed oxide film properties by Electron Probe Microanalysis (EPMA) with energy dispersive X-ray spectroscopy (EDS) at an SEM.
Class II hydrophobins are amphiphilic proteins produced by filamentous fungi with the tendency to accumulate at the air-water interface. They show unusual adsorption kinetics with a coverage-independent adsorption rate, which was monitored with ellipsometry and atomic force microscopy. A theoretical model was introduced to identify the underlying mechanism.
