Abstract: The interaction between α-Fe2O3 powders and methanol, ethanol, propan-1-ol and butan-1-ol has been studied by means of FTIR and XPS. Mass spectrometry has been used to characterise the volatile products. Methanol is chemisorbed mainly dissociatively whereas molecular chemisorption is prevalent in higher alcohols. When methanol is chemisorbed, heating induces the formation of formate (at temperatures >400 K) while hydrocarbons are the main products (at temperatures >500 K) of the other alcohols. Considerations are made concerning surface acidic sites in connection with the thermal treatment of the sample and with alcohol chemisorption.

TL;DR: In this article, the authors show that the amount of interlayer contraction and the strain energy resulting form the trigonal distortion are very well predicted by a strain analysis in the framework of simple linear elasticity theory.

TL;DR: In this article, the surface sensitivity of angle-scanned photoelectron diffraction applied to bulk crystals or epitaxial multilayers can be enhanced by exploiting the angular anisotropy of the primary wave excited by linearly polarized light, combined with the possibility of performing measurements in two different light polarization/electron detection geometries.
