This study introduces the Theokane number () as a groundbreaking dimensionless number in Electrochemistry. enables the determination of the operating state of an electrochemical (EC) system—indicating whether it is in a transient state (characteristic of cyclic voltammetry) or a steady state (typical of linear sweep voltammetry)—based on a given combination of potential scan rate and residence time. It aims to bridge the gap between various voltamperometric methods. uniquely compares the duration of the potential scan applied to an EC system to the residence time of the reaction mixture at the electrode. This comparison is pertinent in environments ranging from microfluidic setups to macroscale reactors, including stirred vessels.

打破电化学的界限：推出新的无量纲数来解决伏安法答案上的对流传递效应

这项研究引入了 Theokane 数 () 作为电化学中突破性的无量纲数。能够根据给定的电位扫描速率组合确定电化学 (EC) 系统的工作状态，表明其是处于瞬态（循环伏安法的特征）还是稳态（线性扫描伏安法的典型特征）和停留时间。它旨在弥合各种伏安法之间的差距。独特地将施加到 EC 系统的电位扫描持续时间与反应混合物在电极上的停留时间进行比较。这种比较适用于从微流体装置到宏观反应器（包括搅拌容器）的各种环境。
