Lanthanide Monoporphyrinates and Complexes With a Schiff Base Derivative: Thermodynamic Stability and Bioimaging Capabilities

open access: yesChemistry–Methods, Volume 6, Issue 5, May 2026.
This study provides new data for the stability constants of lanthanide complexes using spectrometric methods with different approaches, considering the stability differences. Clinical applications ranging from magnetic resonance imaging to cancer therapy are more relying on the use of lanthanide coordination compounds.

Anchorage System Contribution to Post‐Tensioned Bridge Collapse

open access: yesEngineering Reports, Volume 8, Issue 5, May 2026.
This paper presents an experimental investigation of a 1960s precast post‐tensioned girder bridge in Trstena, Slovakia, revealing severe corrosion and anchorage degradation that ultimately led to its collapse. The findings highlight critical vulnerabilities in obsolete anchorage systems and emphasize the need for proactive assessment and maintenance of

Charge Regulation in Crowded Solutions of a Weak Polyelectrolyte: Steric Interactions

open access: yesIsrael Journal of Chemistry, Volume 66, Issue 3, May 2026.
Weak polyelectrolytes (WPE) solvated in biorelevant media and synthetic complex fluids that contain substantial concentrations of macromolecules, molecular assemblies, and nanoparticles are observed to exhibit deviations from the acid–base equilibrium observed in single‐component solutions.

Supercapacitive Carbon‐Coated δ‐MnO2 Nanosheets as a Solid‐Contact Material for Self‐Testing Potassium‐Ion Biosensors

open access: yesSmall, Volume 22, Issue 26, 8 May 2026.
A simple and energy‐efficient method was developed to synthesize carbon‐coated δ‐MnO2 nanosheets (δ‐MnO2@C). This multifunctional material serves as both a supercapacitor electrode and a solid‐contact for self‐testing K+‐ion biosensors. Compared to activated carbon, δ‐MnO2@C enhances Faradaic supercapacitive properties, improving the K+‐ion sensing ...

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

open access: yesJournal 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 ...
