Abstract

DSA type electrodes (IrOx/Ti) were prepd. by induction heating technique which allows a rapid decompn. of the precursor under anaerobic conditions. With this type of electrode, an activation process is obsd. in cyclic voltammetry which can be related to the presence of metallic Ir within the coatings. The electrooxidn. of alcs. in acid medium was studied by cyclic voltammetry. In the presence of alcs., a large current enhancement was obsd. at E >= 1.3 V/normal H electrode. This great reactivity can be due to high iridium oxidn. states, Ir(V) and Ir(VI), present in the oxide layer in this potential range. [on SciFinder (R)]

Type system

In computer programming, a type system is a logical system comprising a set of rules that assigns a property called a type (for example, integer, floating point, string) to every "term" (a word, phrase, or other set of symbols). Usually the terms are various constructs of a computer program, such as variables, expressions, functions, or modules. A type system dictates the operations that can be performed on a term. For variables, the type system determines the allowed values of that term.

Cyclic voltammetry

In electrochemistry, cyclic voltammetry (CV) is a type of potentiodynamic measurement. In a cyclic voltammetry experiment, the working electrode potential is ramped linearly versus time. Unlike in linear sweep voltammetry, after the set potential is reached in a CV experiment, the working electrode's potential is ramped in the opposite direction to return to the initial potential. These cycles of ramps in potential may be repeated as many times as needed.

Hydrodynamic voltammetry

In analytical chemistry, hydrodynamic voltammetry is a form of voltammetry in which the analyte solution flows relative to a working electrode. In many voltammetry techniques, the solution is intentionally left still to allow diffusion-controlled mass transfer. When a solution is made to flow, through stirring or some other physical mechanism, it is very important to the technique to achieve a very controlled flux or mass transfer in order to obtain predictable results.
