Superior Impact‐Resistant Composite Hydrogels Through an Ionic Coupling Strategy

open access: yesAdvanced Materials, Volume 38, Issue 26, 8 May 2026.
An ionic coupling strategy is developed to simultaneously reinforce networks and interfaces in composite hydrogels. Sodium citrate acts as a single multifunctional ionic coupler to strengthen the poly(vinyl alcohol) matrix via the Hofmeister effect, reinforce the chitosan–sodium alginate nanofiber network via desolvation and electrostatic crosslinking,

Large‐Aperture Polarization‐Independent Broadband Achromatic All‐Dielectric Metalens for Terahertz Focusing

open access: yesAdvanced Science, Volume 13, Issue 25, 4 May 2026.
A large‐aperture, high focusing efficiency and polarization‐independent THz single‐layer achromatic metalens is reported via discrete multi‐wavelength achromatic design and global optimization algorithm. The fabricated metalens exhibits a largest diameter of 2.21 cm, excellent achromatic performance, extremely high average focusing efficiency (> 46 ...

A Short‐Rate Model With Stochastic Long‐Term Mean and Volterra‐Type Memory: Risk Implications for Bonds and Option Pricing

open access: yesApplied Stochastic Models in Business and Industry, Volume 42, Issue 3, May/June 2026.
ABSTRACT Traditional short‐rate models introduce volatility directly into the instantaneous rate via Brownian shocks. However, empirical data suggest that short‐term interest rates exhibit smoother behavior than such models imply. We propose a two‐factor Gaussian short‐rate model in which the short rate is a deterministic exponential filter of a ...

Impact of Internal Temperature Stabilisation on Electrochemical Impedance Spectroscopy Based State‐of‐Health Evaluation of Electric Vehicle Battery Modules for Second‐Life Applications

open access: yesBatteries &Supercaps, Volume 9, Issue 5, May 2026.
Thermal stabilisation of EV battery modules is critical for reliable EIS‐based SOH diagnostics. This study shows that stabilisation of module casing temperature does not ensure thermal equilibrium of internal electrochemical processes, potentially leading to significant errors in selected equivalent circuit model parameters.

Aberrant Brain Entropy in Alzheimer's Disease: Evidence From a Resting‐State fMRI Study

open access: yesBrain and Behavior, Volume 16, Issue 5, May 2026.
ABSTRACT Background The neurodegenerative disorder, Alzheimer's disease (AD), is typified by insidious onset and increasing prevalence with advancing age. It primarily causes comprehensive functional decline in memory, language, and executive control.
