Nanostructured films of novel azocompounds

Valdez-Hernandez Y.A., Rivera E., Carreon-Castro M.P., UNAM-Instituto de Ciencias Nucleares, MX

Thin nanostructured films by Langmuir and Langmuir-Blodgett technique of novel azocompounds are reported. Brewster’s angle microscopy (BAM), UV-Visible absorption and atomic force microscopy (AFM) were obtained to determine the stability and quality of the films. [...]

Analysis of Interfacial Water Structure close to Mixed Langmuir Monolayers by Sum-Frequency Spectroscopy

Nickolov Z.S., Britt D.W., Miller J.D., Drexel University, Drexel Nanotechnology Institute, US

Sum frequency spectroscopy (SFS) in the OH stretching region was employed to obtain structural information about the interfacial water structure underneath Langmuir monolayers on H2O subphase. The films were composed by the model lipid dioctadecyldimethylammonium [...]
