EQCM behavior of copper anodes in alkaline medium and characterization of the electrocatalysis of ethanol oxidation by Cu(III)

Journal of the Brazilian Chemical Society, 2006
The anodic oxidation of copper electrodes in alkaline solutions was investigated by using voltammetry, chronoamperometry, impedance measurements and the electrochemical quartz crystal microbalance (EQCM). Experiments were carried out in NaOH solutions in

Monitoring Biogenic Amines: Comparative Assessment of Detection Methods for Key Market Marine and Freshwater Species

Journal of Food Science, Volume 91, Issue 5, May 2026.
ABSTRACT Biogenic amines, primarily histamine, cadaverine, and putrescine, are important indicators of microbial spoilage and potential health risks. This review summarizes established and novel analytical methods for quantitatively determining biogenic amines in fish and fish products, along with their limits of detection in these complex matrices ...

Quartz Crystal Microbalance Sensitivity Loss During Ionic Liquid Deposition: Insights into Film Structure and Morphology

ChemPhysChem, Volume 27, Issue 7, 14 April 2026.
Vapor‐deposited ionic liquid films on Au‐coated QCMs evolve from confined, rigidly coupled layers to viscoelastic, bulk‐like overlayers as coverage increases. This transition explains the loss of QCM sensitivity and demonstrates how nanoscale confinement, substrate roughness, and IL properties govern reliable mass detection.
