Microelectrode techniques for in situ measurements on electrical conductance of a carbon particle and its composite film during electrochemical lithium insertion/extraction
Article Abstract:
Research was conducted to examine novel electrochemical techniques based on a filament-type and an array-type microelectrodes. The objective was to analyze in situ the conductance change of a carbon particle and its composite film during electrochemical lithium insertion/extraction reactions. Results provide evidence that microelectrode-based techniques are a unique and effective method in the study of battery active materials from both practical and fundamental standpoints.

The micro-optical ring electrode. 3: Transient photocurrent studies of photophysical-electrochemical and photophysical-chemical-electrochemical systems
Article Abstract:
The preparation and characterization of very thin ring micro-optical ring electrodes (MOREs) with (ring inner radius)/(ring outer radius) > 0.99 is described. It is shown that it is possible to derive asymptotic analytical expressions for the time dependence of the diffusion limited transient light-on photocurrent generated by photochemical-electrochemical (PE) and photophysical-chemical-electrochemical (PCE) systems at very thin ring MOREs.

Imaging microelectrodes with high-frequency electrogenerated chemiluminescence
Article Abstract:
A study was conducted to image microelectrodes supporting dimensions in the micrometer range using the chemiluminescence resulting from the reaction of electrogenerated intermediates of 9,10-diphenylanthracene. Electrogenerated chemiluminescence was determined in a flow injection analysis system. Experimental results indicated that the electrode areas supported different topography than deduced from steadys-state cyclic voltammograms.
