Experimental methods in chemical engineering: Cyclic voltammetry—CV

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Cyclic voltammetry (CV) is a foundational electroanalytical technique for investigating redox behaviour and evaluating material performance across fields such as molecular electrochemistry, electrocatalysis, sensing, and energy storage. Despite its widespread use, a gap remains between formal electrochemical theory and the practical data ...

Recent Paradigms in Nanomaterial‐Assisted Electrochemical (Bio) Sensing for Food Quality and Safety Analysis: A Critical Review

Food Safety and Health, EarlyView.
ABSTRACT Rising global demand for safe and unadulterated foods has accelerated the need for rapid, low‐cost, and portable analytical technologies. Traditional laboratory methods, although accurate, are often labor‐intensive and unsuitable for decentralized, real‐time monitoring. In response, nanomaterial‐assisted electrochemical sensors have emerged as

Cyclic-Voltammetric Observation of Carbonizing Process of Resins

TANSO, 1999
Electrochemical characteristics of several carbon materials prepared from furan resin, imide resin and poly vinylchloride, were studied by cyclic voltammetry in 1M KCl solution and in 5mM Fe (CN) 64-/3--1M KCl solution. Blankcurrent (Ib), potential difference between cathodic and anodic peak (ΔEp) and peakcurrent (Ip) for ferro/ferricyanideredox ...
