Hole Polaronic Confinement in (111) Yttria‐Stabilised Zirconia

open access: yesSmall, Volume 22, Issue 25, 4 May 2026.
Ultrathin epitaxial YSZ(111) films unexpectedly develop p‐type mixed conduction and amplified electromechanical coupling under oxidizing conditions. Combined transport measurements and first‐principles modeling reveal that nanoscale confinement and ordered dopant–vacancy complexes stabilize localized O 2p hole polarons at the surface. A canonical ionic

White Is a New Shade of Blue Carbon: A Case Study of a Traditional Salt Production Pond That is a Net Carbon Sink

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract To address for the first time the carbon budget of traditional salterns, we measured the diel, seasonal, and spatial variability of water‐air CO2‐eq fluxes (CH4 and CO2) and the Organic Carbon (OC) stock and burial rate in the sediment. Temperature, salinity, dissolved oxygen, pH and wind were assessed as potential environmental drivers of the

Nationwide Implementation of Double Reflex Testing for Hepatitis Delta in Spain: Results From the Retrospective Phase of the Spain‐DDR Study

open access: yesAlimentary Pharmacology &Therapeutics, Volume 63, Issue 10, Page 1390-1397, May 2026.
Nationwide implementation of double reflex testing for hepatitis delta in Spain markedly increased anti‐HDV and HDV viral load testing between 2022 and 2024, enabling national seroprevalence estimates. Despite this progress, substantial regional heterogeneity persists, highlighting the need for standardised reflex diagnostic protocols.

Immunocompromised Status Definition in Observational Studies Using Electronic Health Records: A Scoping Review and a Proposal for a Phenotype Identification Algorithm

open access: yesPharmacoepidemiology and Drug Safety, Volume 35, Issue 4, April 2026.
ABSTRACT Immunocompromised individuals experience an impaired immune function due to conditions that might be either congenital or acquired over the course of their lives. Epidemiological studies often rely on clinical definitions which, in some cases, benefit from being translated into machine‐readable algorithms for application to electronic health ...
