Site-specific fragmentation following C:1s core-level photoionization of 1,1,1-trifluoroethane condensed on a Au surface and of a 2,2,2-trifluoroethanol monolayer chemisorbed on a Si(100) surface

Article Abstract:

Site-specific fragmentation following C:1s core-level photoionization of 1,1,1-trifluoroethane condensed on a gold (Au) surface and of a 2,2,2,-trifluoroethanol monolayer chemisorbed on a silicon(100) (Si) surface are studied. Results of the electron-yield spectra and photoelectron spectra reveal the occurrence of site-specific excitations and indicate that the chemical shifts at the C[H] and C[F] sites were different.

AC-modulated voltfluorometric study of the transient adsorption of Rose Bengal dianions in the transfer across the 1,2-dichloroethane/water interface

Article Abstract:

An ac-modulated voltfluorometry of the transfer of Rose Bengal dianions [RB (super 2-)] across the 1,2-dichloroethane (DCE)/ water (W) interface is studied. The slowness of RB (super 2-) ion transfer is likely to be related to slow rotational dynamics of RB (super 2-) ion at the interfacial region and its preferential orientation at the interface.

A mechanism for ion transport across the water/dichloromethane interface: A molecular dynamics study using polarizable potential models

Article Abstract:

The study used molecular dynamics techniques and potential of mean force approach to compute the ion transfer free energy for the water/dichloromethane liquid-liquid interface. A smooth transition from the aqueous phase to the non-aqueous phase on the free energy profile indicates that the ion transfer mechanism is a nonactivated process.
