On electrocatalysis in alkene–molybdenum(VI) system at Pt/acidic solution interface

Hydrogen electrocatalysis: a basic solution.

Electrocatalysis on the nm scale

The past two decades have seen a renewed and rapidly growing interest in the fields of electrochemistry and electrocatalysis. This is on the one hand stimulated by applications in energy conversion and energy storage, where highly efficient electrochemical/electrocatalytic processes are considered to be an indispensable part of modern energy concepts based on the use of renewable energy sources...

Adsorption Kinetics at Silica Gel/Ionic Liquid Solution Interface.

A series of imidazolium and pyridinium ionic liquids with different anions (Cl(-), Br(-), BF₄(-), PF₆(-)) has been evaluated for their adsorption activity on silica gel. Quantification of the ionic liquids has been performed by the use of RP-HPLC with organic-aqueous eluents containing an acidic buffer and a chaotropic salt. Pseudo-second order kinetic models were applied to the experimental da...

Dynamic Sensing of Localized Corrosion at the Metal/Solution Interface

A Mach-Zehnder interferometer is employed to detect localized corrosion at the metal/solution interface in the potentiodynamic sweep of the iron electrode in solutions. During the electrochemical reactions, local variations of the electrolyte's refractive index, which correlate with the concentration of dissolved species, change the optical path length (OPL) of the object beam when the beam pas...

Kinetics of surfactant desorption at an air-solution interface.

The kinetics of re-equilibration of the anionic surfactant sodium dodecylbenzene sulfonate at the air-solution interface have been studied using neutron reflectivity. The experimental arrangement incorporates a novel flow cell in which the subphase can be exchanged (diluted) using a laminar flow while the surface region remains unaltered. The rate of the re-equilibration is relatively slow and ...
