X-ray diffraction studies on pore condensates in silica nanochannels: The interplay of sorption strains, capillary condensation and capillary sublimation phenomena — •Daniel Rau1, Patrick Huber1, Sebastian Mörz1, Wolfram Leitenberger2, and Rolf Pelster1 — 1Universität des Saarlandes, Saarbrücken, Germany — 2Universität Potsdam, Germany
We present investigations on the interplay of capillary condensation, capillary sublimation and sorption strains in molecular assemblies confined in template-grown silica nanochannels (SBA-15). The influence of the spatial restriction on the structure of the pore-condensates as well as the influence of the pore-condensate on the structure of the nanochannel array are investigated by wide- and small-angle x-ray scattering techniques.
