Carbon-13 NMR investigations of the orientational order in a columnar liquid crystal
Article Abstract:
The molecular structure of benzene dissolved in a columnar liquid crystal formed by the carbohydrate mesogen octa-omicron-decanoyl-beta-cellobiose (Cel-II-10) has been investigated using carbon-13 nuclear magnetic resonance (NMR). The orientational order of benzene in a uniaxial liquid crystal is the focus of the research and is limited only to uniaxial molecules in a uniaxial phase. Results indicate that carbon-13 lines are wide and powder-like which suggests that there is only partial alignment of the liquid crystal in the magnetic field. The traces in the right column are characteristic of a disordered uniaxial sample.

Field-dependent NMR relaxation study of aggregation and dynamics in dilute ot concentrate micellar decylammonium chloride solutions
Article Abstract:
2H nuclear magnetic relaxation dispersion in the 0.5-77 MHz frequency range was used to measure the surfactant aggregation behaviour on aqueous decylammonium chloride solutions with concentrations of 5-29 wt% and with a temperature range of 13-55 degrees centigrade.

Shape changes of C16TABr micelles on benzene solubilization
Article Abstract:
Issues concerning the microstructure of C16TABr micelles with solubilized benzene are discussed. It was found that, on benzene addition, the micelles become marginally elongated microemulsion droplets.
