Our research interests involve electroanalytical chemistry (electrochemical technique development, sensors and instrumentation) and physical electrochemistry. Recent and current problems have involved the study of:
- the details of ion and neutral species transport accompanying the redox switching of electroactive polymers
- solid electrodes in order to understand the processes that control reaction at them
- techniques for overcoming nonelastic behavior at the quartz crystal microbalance
- developing planar chromatographic solid phases that yield a separation that are equivalent to an experimentally impractical gradient elution approach.
Th research in (1) and (2) can then be used to control the rates of electrode processes and thus develop new and better analytical methods, electrochemical sensors, electrochemical displays, and energy storage devices. Development of unique instrumentation and techniques has played a key role in our research. The research (3) is aimed at obtaining Sauerbrey responses with viscoelastic molecules, typically those of biological origin. The goal of the research in (4) is lay the foundations for increasing the versatility of a wide variety of 1D chromatographic techniques.
Some recent published research has been concerned with:
- electrochemical and transport processes occurring during the redox cycling of electroactive polymers. This research can then be used to understand the processes that are critical in application of electroactive polymer to analytical sensors, energy storage devices (batteries, supercapacitors), optical displays, corrosion inhibitors and medical devices.
- the properties of a fractional atom layer of a metal deposited on another metal (underpotential deposition). Our object is to understand the thermodynamics and kinetics of such deposition processes and the electrocatalytic behavior of such films. This understanding can lead to improved modified electrodes and electrocatalysts.
- the theory and practice of using the quartz crystal microbalance simultaneously with electrochemical techniques (the so-called “hyphenated” EQCM technique) to study the formation and properties of fractional monolayer, monolayer and thicker inorganic, organic and polymer films at electrodes. The in situ EQCM technique provides detailed insights unavailable by other approaches. It has proved to be extremely valuable in the investigation of the behavior of electroactive polymers and has been widely adopted throughout the world.
