Structure of methanol confined in MCM-41 investigated by large-angle X-ray scattering technique
Article Abstract:
The present large-angle X-ray scattering (LAXS) investigation on methanol confined in the MCM-41 C14 (diameter of 28 Angstrom) and C10 (21 Angstrom) pores has shown that the structure of methanol consists of the monolayer methanol on the surface and the hydrogen-bonded chains of methanol molecules at the central part of the pores. The methanol structure cannot be three-dimensionally evolved in the pores with decreasing temperature.

Negative dipole potentials of unchanged Langmuir monolayers due to fluorination of the hydrophilic heads
Article Abstract:
The uncharged Langmuir monolayers of docosyl trifluoroethyl ether (DFEE) exhibit large negative dipole potentials, and the nonfluorinated docosyl ether (DEE) forms films with positive dipole potentials. The conclusion orients the future synthesis of amphiphiles with fluorinated heads to those, which could form liquid expanding Langmuir monolayers.
