Beer's law and the isosbestic points in the absorption spectra of conductive polymers
Article Abstract:
Research was conducted to examine Beer's law and the isosbestic points in the absorption spectra of conductive polymers that are known to be valid in dilute solutions. It is shown that the proper account of the dispersion of the effective field of the lightwave in a condensed medium aids in circumventing an incorrect interpretation of experimental data. Results also suggest that certain apparent deviations from Beer's law and linear additivity of spectra can be explained without resorting to the presence of additional absorbing components.

Formation of self-assembled monolayer via the electrospreading of physisorbed micelles of thiolates
Article Abstract:
The oxidation and reduction of hexadecanethiols chemisorbed on Au(111) was investigated via a spectroelectrochemical approach. Results showed that the reductive desorption and the oxidative redeposition proceeded through two steps due to the decrease of the solubility of the alkanethiols. Based on these findings, a new model was developed for the electrodeposition of insoluble thiols that involves the electrospreading of physisorbed micelles of thiolates.

Mechanism of reductive desorption of self-assembled monolayers on the basis of Avrami theorem and diffusion
Article Abstract:
A mathematical model for the reductive desorption of self-assembled monolayers is developed which is based on the model in which desorption occurs as growing empty patches. The overlap of patches is described by using Avrami theorem, and the diffusion rate or the desorbing compound is taken into account.
