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 ...

Decoupled Interface Passivation Enabled by Directional Ion Migration in Lithium‐Ion Batteries

Small, EarlyView.
An additive with individually functionalized cation and anion components bearing complementary film‐forming functionalities is designed for incorporation in lithium‐ion battery electrolytes. The cations and anions migrate under electrochemical polarization and selectively decompose at opposite electrodes, The resulting decoupled passivation suppresses ...

Revisiting Electrolyte Effects in Oxygen Evolution Reaction on NiOOH: pH‐Controlled Activity Depends on Catalyst Mesostructure

ChemElectroChem, Volume 13, Issue 18, 19 September 2026.
pH and electrolyte composition significantly affect the oxygen evolution activity of NiOOH, with the extent of the pH effect depending on layer morphology. Porous, heterogeneous layers show a strong pH dependence, while thin, dense layers exhibit only a weak effect, resulting in distinct pH‐activity trends.

Selenophene π‐Bridge Enables Balanced Ambipolar Transport in High‐Performance Organic Electrochemical Transistors

Advanced Science, Volume 13, Issue 49, 3 September 2026.
We synthesized a high‐performance balanced ambipolar OECT polymer, P(gTDPPSe), via selenophene π‐bridge engineering. The selenophene π‐bridge enhances backbone planarity and optimizes the energy levels for doping, enabling high and balanced p/n‐type transconductance‐a key factor for high‐gain complementary inverters.
