Boosting Piezoelectric Voltage Constant in 3D‐Interconnected PZNNT Porous Piezoceramics via Pore Architecture Engineering

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT In conventional piezoceramics, the coordinated change between the dielectric constant (εr) and the piezoelectric charge constant (d33) usually limits the piezoelectric voltage constant g33 (g33 = d33/εr), a critical figure of merit for piezoelectric sensors.

Plasma‐Boosted Bi2Mn4O10 Electrocatalysis Enables Real‐Time On‐Board Monitoring of CO2 in Exhaust

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Real‐time monitoring of CO2 concentration in automobile exhaust is critical for effective carbon emission reduction. However, the inherently inert nature of CO2 poses a significant challenge for achieving accurate and efficient detection in the exhaust automobile environment.

Ru‐Ag Dual Atom Sites for Methane Detection Enabling Intelligent Thermal Runaway Warning in Lithium‐Ion Batteries

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Early detection of thermal runaway (TR) is essential for lithium‐ion battery (LIB) safety, as unchecked TR risks catastrophic failures in energy storage systems. Gas‐based sensing offers a faster and more direct approach by detecting decomposition products at the molecular level.

Engineering Fully‐Exposed Ir Clusters on Tin Oxide Surface for Highly Sensitive and Stable H2 Sensing

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Metal oxide semiconductor‐supported noble metal nanoparticles are common sensing materials for gas sensors. However, the large size and their tendency to migrate at high temperatures often lead to inferior sensing sensitivity and stability. Herein, a salt‐assistant strategy is developed to prepare fully‐exposed Ir clusters on SnO2 nanorods ...

Allometric Scaling in Environmental DNA Concentration of Japanese Eel Anguilla japonica Confirmed Under Laboratory and Natural Conditions 日本鳗 (Anguilla japonica) 环境 DNA 浓度中的异速生长标度在实验室和自然条件下得到证实

open access: yesIntegrative Conservation, Volume 4, Issue 4, Page 675-685, December 2025.
We demonstrated that Anguilla japonica eDNA concentration was allometrically scaled with their body size in both the laboratory and riverine environments. Integrating body size allometry has the potential to improve population abundance estimates in the field, whereas further clarification is required for understanding eDNA production mechanisms ...

A novel approach for feline sporotrichosis pathogen detection based on loop‐mediated isothermal amplification

open access: yesVeterinary Dermatology, Volume 36, Issue 4, Page 474-484, August 2025.
Background – Sporotrichosis is a chronic, mycotic infection caused by fungi of the genus Sporothrix. Zoonotic sporotrichosis occurs mainly through S. brasiliensis transmission, resulting from the organism's traumatic introduction via scratches or bites, or contact with exudate from contaminated cats.

N‐terminal pro B‐type natriuretic peptide as biomarker to predict pre‐eclampsia and maternal–fetal complications

open access: yesUltrasound in Obstetrics &Gynecology, Volume 65, Issue 4, Page 447-455, April 2025.
ABSTRACT Objective A soluble fms‐like tyrosine kinase‐1 (sFlt‐1)‐to‐placental growth factor (PlGF) ratio cut‐off of 38 is currently considered optimal for ruling out pre‐eclampsia (PE); however, implementation of this ratio in clinical practice is limited.
