Electroanalytical and physical electrochemistry at solid electrodes; electroactive polymers development of new analytical techniques; sensors and instrumentation; hydrodynamic voltammetry; electrochemical quartz crystal microbalance development and applications, novel chromatographic solid phases.
Our research interests involve electroanalytical chemistry (electrochemical technique development, sensors and instrumentation) and physical electrochemistry. Recent and current problems have involved the study of:
(1) the details of ion and neutral species transport accompanying the redox switching of electroactive polymers
(2) solid electrodes in order to understand the processes that control reaction at them
(3) techniques for overcoming nonelastic behavior at the quartz crystal microbalance
(4) developing planar chromatographic solid phases that yield a separation that are equivalent to an experimentally impractical gradient elution approach.
The 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.
