Turning Electrode Orientation into a Design Parameter: Gravity‐Driven Convection for Coupling Electrochemical and Enzymatic Reactions

ChemElectroChem, Volume 13, Issue 11, 3 June 2026.
Electrochemically induced density gradients are harnessed to drive gravity‐dependent convection at partially fouled electrodes. By controlling electrode orientation and surface heterogeneity, mass transport is enhanced without external stirring. This enables coupling of electrochemical reactions with enzyme catalysis on insulating domains, exemplified ...

A New Kinetic‐Mechanistic Approach Towards Spectrophotometric Bioanalysis of 2‐Phenylethylamine as a Sympathomimetic Agent Using Sodium Isopropyl Xanthate

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT 2‐Phenylethylamine (2‐PEA), an aromatic biogenic amine, demonstrates significant physiological and toxicological effects on human health. A variety of conventional methods have been widely used for the determination of 2‐PEA. However, the necessity of complex sample preparation and high cost of instrumentation may pose challenges to their ...

Ophiopogonin D Mediates Therapeutic Effects on Primary Sjögren's Syndrome by Modulating Gut Microbiota and Metabolite Profiles

Biomedical Chromatography, Volume 40, Issue 6, June 2026.
ABSTRACT This study aimed to investigate the mechanism of ophiopogonin D (OD) in treating primary Sjögren's syndrome (pSS) through integrated analysis of gut microbiota and metabolomics. Non‐obese diabetic/LtJ mice, a well‐established pSS model, were used as the model group and treated with OD or hydroxychloroquine.
