Summary: The cyclic voltammetry testing method for methanol electrooxidation is commonly used to find anodic catalysts for direct methanol fuel cells. The ratio of peak currents is often used to evaluate CO tolerance of Pt-based catalysts, but in this study it is shown that both peak currents are related to methanol consumption at the electrode surface. The peak area ratio is proposed as a criterion related to the overlap between methanol oxidation potentials and the reduction potentials of the oxidized surface.

Summary: This study presents a label-free aptamer biosensor based on gold nanoparticles/multi-walled carbon nanotubes @ titanium dioxide (AuNPs/MWCNTs@TiO2) for sensitive detection of malachite green (MG). The nanocomposite provides a large surface area and good electrical conductivity, facilitating aptamer immobilization. The detection is achieved by measuring the change in electrical signal resulting from the detachment of aptamer from complementary chain (cDNA) and binding to MG. Under optimal conditions, the sensor demonstrates good linearity and a low limit of detection (LOD).

Summary: This paper presents a theoretical analysis of reversible and quasireversible electrode reactions of a dissolved redox couple under the conditions of differential square-wave voltammetry (DSWV), a recently introduced hybrid technique combining the advantages of differential pulse voltammetry (DPV) and square-wave voltammetry (SWV). The potential modulation of DSWV involves potential steps and pulses, providing a variety of voltammetric curves that allow for a comprehensive characterization of the electrode reaction with a minimal number of measurements. Based on numerical simulations, criteria for characterizing and differentiating between reversible and quasireversible electrode reactions are established.
