Lateral diffusion of reconstituted alkylferrocenecarboxamide/phosphatidylchloline lipid monolayer at the air/water interface studied with electrochemistry

Article Abstract:

A study was conducted to determine the lateral diffusion of reconstituted alkylferrocenecarboxamide/phosphatidylchloline lipid monolayer at the air/water interface studied using electrochemical methods. The homogeneity was analyzed with pressure-area isotherms. Results indicated that a high molar ratio resulted in an inhomogeneous monolayer. In addition, decreases in mean molecular area was correlated with decreases in the free area of the monolayer molecules at the air/water interface.

Electrochemical studies of the lateral diffusion of TEMPO in the aqueous liquid/vapor interfacial region

Article Abstract:

Surface partitioning and lateral mobility of TEMPO (2,2,6,6-tetramethyl-1-piperidynloxy free radical) in the aqueous liquid/gas interfacial region were investigated electrochemically with 100 nm wide 1.0 cm long microband electrodes positioned at the air/water interface. The electronic structure calculations showed that a single water molecule forms a hydrogen bond with TEMPO that is approximately 30% stronger than the H(sub 2)O-H(sub 2)O hydrogen bond.

The reorganization energy of Azurin in bulk solution and in the electrochemical scanning tunneling microscopy setup

Article Abstract:

A computational model for the evaluation of outer reorganization energies for proteins in bulk solutions and in the electrochemical scanning tunneling microscopy (ECSTM) setup is presented and applied to Azurin (Az). The model is based on an accurate description of the protein active site coupled to a continuum description of the remainder of the system.

Usage, Scanning tunneling microscopy
