Formation and Characterization of Insoluble Anthocyanins‐λ‐carrageenan Biopolyelectrolyte Complexes: Structural Morphology, Thermal Stability, and Release Dynamics

open access: yesChemFoodChem, EarlyView.
Insoluble biopolyelectrolyte complexes formed between blackberry anthocyanins and λ‐carrageenan are investigated. Optimal complexation occurs at low carrageenan ratios and acidic pH, producing porous hydrogel‐like structures with enhanced thermal stability.

Investigation on hard‐rock breaking performance and auxiliary mechanism of picks assisted with both‐sided high‐pressure water jets

open access: yesDeep Underground Science and Engineering, EarlyView.
This paper investigates the high‐pressure water jet‐pick combined rock‐breaking mode (HPC), which employs high‐pressure water jets to precut grooves on both sides of the picks. The rock‐breaking patterns and performance of the HPC method are obtained, and the auxiliary rock‐breaking mechanism of water jet grooving is revealed.

Comprehensive Analysis of the Degradation Phenomena of Proton Exchange Membrane Water Electrolyzers with Iridium on Antimony Tin Oxide Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study examines the structural and chemical evolution of low‐loaded Ir/ATO anodes during PEM water electrolysis under realistic conditions. Iridium dissolution is largely suppressed. In the early stages, both ionomer and support degradation are detected. Morphological reorganization occurs at the interface between the anode catalyst layer (ACL) and

SPARCL1 and NT‐proBNP as biomarkers of right ventricular‐to‐pulmonary artery uncoupling in pulmonary hypertension

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1416-1426, April 2025.
Abstract Aims SPARCL1 was recently identified as a biomarker of right ventricular (RV) maladaptation in patients with pulmonary hypertension (PH), and N‐terminal pro‐brain natriuretic protein (NT‐proBNP) is an established biomarker of RV failure in PH. The present study investigated whether NT‐proBNP and SPARCL1 concentrations are associated with load ...
