Electrochemical Charge Transfer Reaction Kinetics at the Silicon-Liquid Electrolyte Interface

Probing charge screening dynamics and electrochemical processes at the solid-liquid interface with electrochemical force microscopy.

The presence of mobile ions complicates the implementation of voltage-modulated scanning probe microscopy techniques such as Kelvin probe force microscopy (KPFM). Overcoming this technical hurdle, however, provides a unique opportunity to probe ion dynamics and electrochemical processes in liquid environments and the possibility to unravel the underlying mechanisms behind important processes at...

Electrochemical modulation of SERS at the liquid/liquid interface.

A surface enhanced Raman scattering system to detect silver nanoparticle adsorption at the water|1,2-dichlorobenzene interface is reported. The Raman response as a function of distance on either side of the interface reveals a reproducible spatial variation, which is potential dependent for a number of adsorption and desorption cycles.

Erratum: Theory of charge transfer at the high-Tc superconductor/electrolyte interface

Heterogeneous electron transfer kinetics at the ionic liquid/metal interface studied using cyclic voltammetry and scanning electrochemical microscopy.

The electrochemical behavior of a redox-active, ferrocene-modified ionic liquid (1-ferrocenylmethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide) in acetonitrile and in an ionic liquid electrolyte (1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide) is reported. Reversible electrochemical behavior was observed in each electrolyte with responses typical of those for unmodifie...

Studies of charge transfer at liquid liquid interfaces and bilayer lipid membranes by scanning electrochemical microscopy

The principles of scanning electrochemical microscopy (SECM) and its application to studies of electron transfer at the interface between two immiscible electrolyte solutions are reviewed. The results of SECM measurements with a number of redox couples at the bare liquid liquid interface or an interface with a lipid monolayer suggest that the electron transfer follows that predicted by Marcus t...
