This focus issue of the Journal of The Electrochemical Society is a collection of papers on cutting-edge research by members of the Society for Electroanalytical Chemistry (SEAC). SEAC members work in diverse fields of electrochemistry including the fundamental study of the electrochemical interface, nanoelectrochemistry, electrochemical sensors, spectroelectrochemistry, electrochemical imaging, in vivo and in vitro analysis, and energy conversion and storage. The Society, founded in 1984, is dedicated to promoting advances in both basic and applied research in electroanalysis; providing a venue for the exchange of ideas among researchers from academia, industry, and government; and recognizing the achievements and contributions of scientists who work in the field of electroanalytical chemistry. This focus issue will publish exciting cutting-edge research papers at the frontier of modern electroanalytical chemistry. (more…)
