Research on the vesicle-micelle transition by (super 1)H NMR relaxation measurement
Article Abstract:
The dynamics of surfactant molecules which change with the vesicle-micelle transition are investigated by (super 1)H NMR relaxation studies on the sodium decyl sulfate (SDeS)-decyltrimethylammonium bromide (DeTAB)-deuterium oxide system. The SDeS-DeTAB system shows that with micelle or vesicle formation, the molecular motion becomes slower than the monomer one and the shift of the resonant frequency to the lower magnetic filed observed for the micellar and vesicular solutions reflects that surfactant molecules are constrained near each other in the micelle and vesicle particles.

Possible A1-F bonding environment in fluorine-bearing sodium aluminosilicate glasses: from calculation of (super 19)F NMR shifts
Article Abstract:
The F NMR chemical shifts for possible AI-F species in sodium aluminosilicate glasses are described by using Hartree-Fock and hybrid Hartree-Fock density functional methods at the 6-311+G-(2df,p) basis set level calculations. Several well-characterized methods are used to calculate the F NMR shifts and a clear trend is observed between the chemical composition of the environment and the F-NMR shift.

Depositional characteristics of metal coating on single-crystal TiO2 nanowires
Article Abstract:
Ultralong single-crystalline TiO2 nanowires were prepared by a simple, low-cost solvothermal process. Silver nitrate, neodymium chloride, ceric nitrate, stannic chloride hydrate, and cadmium chloride were used as metal sources and deposited by reduction on the surface of TiO2 nanowires.
