Electrochemistry and education

Electrochemistry.

F or this special issue of PNAS, it seems appropriate to begin with a brief commentary on the path(s) leading to where the discipline of electrochemistry is today. The papers in this issue serve as a sampling of the current themes and directions; we thank the authors for their contributions. We should also point to a nice collection of historical perspectives gathered together by Leddy et al. (...

Electrosynthesis and electrochemistry

Since the pioneering work of Kolbe, electrochemistry and electrosynthetic methods have been a part of the repertoire of the organic synthesis toolbox [1,2]. In general, only electrons are employed as reagents or the reagents are electrochemically regenerated. Consequently, waste can be avoided, and limited resources can be used in a careful and economic manner. Because alternative reaction path...

Direct Electrochemistry of Polyphenol Oxidase

The electrochemistry of banana tissues on a carbon paste electrode modified with multi-walled carbon nanotubes (MWCNTs) is presented. Cyclic voltammetry is applied to investigate the direct electrochemistry of banana tissues i.e. a source of polyphenol oxidase (PPO). A redox couple with an anodic and counterpart cathodic peak is obtained. The influence of various parameters such as pH,...
