Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

open access: yesAdvanced Materials, EarlyView.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

Label‐Free Sensing of Coronaviral Sequences via Kretschmann‐Configuration Reflectance Spectroscopic Ellipsometry: Sensitivity, Specificity, and Interfacial Effects

open access: yesAdvanced Materials Interfaces, EarlyView.
Spectroscopic ellipsometry in the Kretschmann‐Raether configuration (KRSE) is employed to characterize a DNA‐functionalized platform for viral sequence recognition. By merging SE with surface plasmon resonance, KRSE outperforms conventional SE, achieving nanomolar targeting through resonance wavelength shifts (δλ) measurements. Its enhanced interfacial

Unveiling Complementary Unipolar Electrical Transport in ZnO‐Co3O4 Core–Shell Nanowires Exploiting Iontronics

open access: yesAdvanced Materials Technologies, EarlyView.
Complementary unipolar electrical transport is demonstrated in ZnO‐Co3O4 core–shell nanowires, by engineering multi‐terminal device architectures that allow to selectively address different sections of the nanostructure and resorting on ionic liquid gating for conformal capacitive coupling and field effect control.
