Location of butanol in mixed micelles with alkyl glucosides studied by SANS
Article Abstract:
Small-angle neutron scattering has been used to determine the location of alcohol molecules or butanol in the micelles of beta-D-octyl glucopyranoside, beta-D-decyl maltopyranoside and beta-D-dodecyl maltopyranoside. These surfactants contain saccharide residues as their hydrophilic moiety and are made up of a mixture of homologous alkyl glucosides with various hydrocarbon chain lengths. Results indicate butanol acts as a cosurfactant which is enriched at the interface separating the hydrophobic from the hydrophilic region of the micelles.

Formamide in reverse micelles: restricted environment effects on molecular motion
Article Abstract:
New aerosol OT (AOT) reverse micelles to be used in solubilizing formamide instead of water have been synthesized. Infrared spectroscopy is used to study vibration of deuterated formamide solubilized in AOT reverse micelles and the solvation of formamide within the micelles. There is no change in the vibrational spectra of the highly-structured, hydrogen-bonded solvent from the bulk liquid spectrum. The solvation of formamide in the reverse micelles reveals the absence of bulk solvent motion.

Multilayer formation of a series of chiral liquid crystal molecules at the air/water interface
Article Abstract:
The multilayer formation of a series of chiral liquid crystal molecules at the air/water interface has been studied by measuring their pi-A and surface potential-area isotherms. It has been discovered that some smectic liquid crystal molecules deposited on solid substrates by thermal evaporation in vacuum can have layered structures. The self-assembly of L2, L4, L6 and L8 on water is linked with their hydroxyl and with the number of CH2 groups in the terminal group.
