Formation of long-lived silver clusters in aqueous solution by anodic dispersion
Article Abstract:
Long-lived, subnanometer-sized silver clusters can be synthesized by anodic dispersion of a silver electrode in aqueous NaOH solutions (pH 10.5-12) without stabilizing polymers. The synthetic approach involves the application of a direct current voltage between two silver electrodes and produces a variety of clusters, oxides and colloids. The oxides and large metallic colloids can be removed by centrifugation, leaving small clusters and colloids in the solution.

Toward infinite-dilution voltammetry
Article Abstract:
A study was conducted to determine reversible half-wave potentials for two reduction waves of 7,7,8,8-tetracyanoquinodimethane and the oxidation wave of ferrocene using steady-state microelectrode voltammetry. Microelectrodes were utilized to minimize the effects of solution resistance. Experimental results indicated the feasibility of determining measurements of half-wave potentials at low electrolyte concentrations using microelectrodes.
