Sorption and pore condensation behavior of nitrogen, argon, and krypton in mesoporous MCM-48 silica materials
Article Abstract:
Results of a systematic study on the sorption- and phase behavior of nitrogen, argon, and krypton at 77 and 87 K in different pristine mesoporous MCM-48 silica phases (BJH pore diameters 2-3nm) and MCM-48 silica iron(III) host compound are presented. Different methods were used to analyze nitrogen (77 K) and argon (87 K) sorption isotherms in order to characterize the MCM-48 silica materials with respect to surface area, pore volume and pore diameter.

Effect of argon plasma treatment on surface-enhanced Raman spectroscopy of polypyrrole deposited on electrochemically roughened gold substrates
Article Abstract:
Polypyrrole (PPy) films were electrodeposited on electrochemically roughened gold substrates modified by argon plasma treatment. The surface-enhanced Raman scattering (SERS) spectroscopy of polypyrrole electrodeposited on this roughened gold substrate modified by argon plasma treatment exhibits a higher intensity by 8-fold, as compared with the SERS of PPy electrodeposited on an unmodified roughened gold substrate.

SANS investigation of nitrogen sorption in porous silica
Article Abstract:
The analysis of the small-angle neutron scattering (SANS) data shows that the mean size of the remaining empty mesopores formally increases, and their size distribution becomes narrower during capillary condensation. The combination of SANS and nitrogen sorption was used to elucidate the mechanism of nitrogen sorption in different meso- and microporous silicas with regular as well as disordered pore structures.
