Effect of surface pressure on oxygen transfer across molecular monolayers as the air/water interface: scanning electrochemical microscopy investigations using a mercury hemispherical microelectrode probe

Article Abstract:

Investigations of the kinetics of molecular transfer across the liquid/gas interface and the effect of a molecular monolayer are used as a model for certain biological and environmental processes. A combined scanning electrochemical microscopy (SECM)-Langmuir trough technique is used to analyze the effect of the chemical character and mechanical compression of molecular monolayers on the rate of oxygen transfer across the air/water (A/W) interface.

Electrowetting measurements with mercury showing mercury/mica interfacial energy depends on charging

Article Abstract:

The interfacial energy between mercury and mica is a function of charge on the mercury surface, decreasing with increasing positive charge is discussed. The high inherent surface charge densities present at mercury interfaces mean that the potentials required to effect significant contact angle changes in this system are of much smaller magnitude than those required to alter the contact angle of an aqueous phase contacting an insulating film.

Force field optimization for organic mercury compounds

Article Abstract:

Organic mercury compounds can be found in petroleum and natural gas production very small concentrations since the experiments are difficult to perform due to very high toxicity of these molecules. For this purpose, a force field including electrostatic interactions are developed to be able to obtain these properties by molecular simulation.
