Theoretical studies on electrocompression of electrodeposited halide monolayer on Au(111) surface

Article Abstract:

The electrocompression behavior of electrodeposited halide monolayer at the electrode surface of Au(111) may be investigated using a simple physical model and theory. Calculations of the statistical thermodynamic formulas, effective pair interaction energy, two dimensional spreading pressure, two dimensional isothermal compressibility and electrode potential-coverage yield results that are in agreement with experimental measurements. The calculations show that the adatom-adatom interactions, such as repulsive interactions, determine the compressibility of the halide adlayer.

Interfacial molecular recognition. Binding of ferrocenecarboxylate to beta-aminocyclodextrin hosts electrostatically immobilized on a thioctic acid monolayer

Article Abstract:

A study was conducted to analyze the interfacial binding characteristics of electrodes determined by the electrostatic immobilization of an adlayer of positively-charged beta-aminocyclodextrin hosts on a self-assembled monolayer of thioctic acid on gold using Osteryoung square wave voltammetry. The gold bead working electrodes were prepared by annealing the tip of a gold wire in a gas-oxygen flame. The roughness factors of the electrodes were then determined between the range of 1.1 to 1.2.

Closed form results for shape transitions in lipid monolayer domains

Article Abstract:

A study was conducted to analyze closed form results associated with shape transitions in lipid monolayer domains. Asymptotic behavior was determined in different limits of interest. A general closed form expression was then obtained for the critical domain radii. Results indicated that lipid monolayers establish two-dimensional domains because of the competition between line-tension and long-range repulsive interactions.
