Molecular structure of lead N-Octadecanoyl-L-alaninate Langmuir-Blodgett Film

Article Abstract:

Pb(super 2+) ion exchange in N-octadecanoyl-L-alanine Langmuir-Blodgett film is investigated by FTIR spectroscopy. The condensation effect of Pb (super 2+) gives rise to significant increase in the hydrogen-bonding interaction between adjacent molecules, so that a complete ion exchange occurs after Pb (super 2+) penetrates into the Langmuir-Blodgett film through structure defects.

Unified crystallographic, Langmuir layer, and Langmuir-Blodgett film investigation of novel amphiphiles based on 4-nitroaniline

Article Abstract:

The crystal structure investigation and Langmuir-Blodgett film study of new amphiphiles based on the 4-nitroaniline moiety of interest in quadratic nonlinear optical applications are presented. An approach to stabilize them through the formation of composite bilayers with the phospholopid molecule, distearoylphosphatidylcholine (DSPC), is developed.

Pressure-induced phase transitions in PbTi[O.sub.3]: A query for the polarization rotation

Article Abstract:

The phase instability's role in understanding the piezoelectricity in systems like Pb(Zr, Ti)[O.sub.3] is examined. The results have shown that the phase instability, in contrast with polarization rotation, is responsible for the large piezoelectric properties of systems like Pb(Zr, Ti)[O.sub.3] in the vicinity of the morphotropic phase boundary.
