Evaluation of a non‐radioactive rapid test for determination of serum progesterone in South American camelids

Veterinary Record, EarlyView.
Abstract Background Determination of the serum progesterone (P4) concentration is of high importance in reproductive medicine and may be applied for diagnosing pregnancy in South American camelids. P4 measurements in alpacas and llamas are usually performed using immunoassays, which are time consuming and require appropriate expertise of laboratory ...

Karst Vadose Zone Hydrology Explored Through Cave Drip Water Dynamics: The Roles of Soil, Epikarst and Climate

Hydrological Processes, Volume 40, Issue 6, June 2026.
Cave drip rate monitoring in Nova Grgosova Cave reveals three types of drip sites: (1) predominantly constant, (2) seasonally varying and (3) mostly constant with occasional sharp increases. The observational data coupled with one‐dimensional water‐balance model demonstrates that evapotranspiration and soil–epikarst storage, rather than precipitation ...

Atomically Thin Sn:GaN‐GaN Homojunction for High‐Sensitivity β‐Ray Detection

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Gallium nitride (GaN), a third‐generation wide‐bandgap semiconductor renowned for its superior radiation tolerance, holds promise for advanced β‐ray detection. Herein, a scalable liquid metal‐assisted in situ synthesis method is presented to fabricate Sn‐doped GaN homojunctions via gallium oxide printing followed by ammonolysis, enabling ...

Calcium and Multi‐Isotope Constraints on Cation Exchange in Groundwater

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Cation exchange is one of the most important processes in water‐rock interaction in the presence of clay minerals, with a common Ca‐Mg‐Na exchange system. However, systematic verification of Ca isotopes for tracing cation exchange in natural environments is lacking due to overlapping factors, such as dissolution‐precipitation of Ca‐minerals ...

Nanocrystal Quality–Controlled Scintillation in Porous YAG:Ce Aerogels

Advanced Optical Materials, Volume 14, Issue 19, 22 May 2026.
High‐temperature thermal treatment of YAG:Ce nanoscintillator aerogels increases light yield under ionizing radiation by up to eightfold without affecting timing performance. Additionally, low‐temperature atmospheric treatments reversibly modify the cerium oxidation state, revealing strong defect sensitivity and offering new strategies to optimize ...

New Insights in the Electrochemical Stability of Various Solid Polymer Electrolytes/Layered Positive Metal‐Oxide Electrode Interfaces in Solid‐State Lithium‐Ion Battery

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 3, May 2026.
In this work, the electrochemical compatibility of a broad range of solid polymer electrolytes with two Ni‐rich nickel–manganese–cobalt cathodes (NMC622, NMC811) is investigated through a hybrid computational and experimental approach. The relative reactivity of NMC811 to NMC622 is demonstrated, as well as the role of Li cations in the electrolyte ...

Bacterial Cellulose Synthase Catalyzes the Formation of Chitin

ChemistrySelect, Volume 11, Issue 15, 20 April 2026.
Recombinant BcsA‐B from Rhodobacter sphaeroides is shown to cleave UDP‐GlcNAc (uridine diphosphate N‐acetylglucosamine), generating chitin with distinct β‐chitin Raman bands. These findings reveal that a cellulose synthase can process an alternative nucleotide sugar, providing biochemical evidence for the co‐synthesis of cellulose and chitin.
