A Test Function Method for Weakly Coupled Systems With Derivative‐Type Nonlinearity

open access: yesMathematische Nachrichten, Volume 299, Issue 10, Page 3015-3035, October 2026.
ABSTRACT We consider a two by two system of inequalities which include fractional powers of the Laplace operator, coupled through a semilinear term of derivative type. We prove the nonexistence of global‐in‐time weak solutions for powers below the critical curve and possibly on the critical curve.

An Integrated Metabolomics and Bioactivity Approach to Characterize Salvia heldreichiana and Salvia tomentosa Extracts

open access: yesChemistryOpen, Volume 15, Issue 10, October 2026.
S. heldreichiana and S. tomentosa can be considered as effective sources of natural bioactive agents for further in vivo pharmacological evaluation and development. The genus Salvia, widely known as sage, represents the largest group within the Lamiaceae family and includes numerous species with traditional uses.

Almond Shell‐Derived Cellulosic Microfibres: Extraction, Characterisation and Applications in Sustainable Paper‐Based Packaging

open access: yesPackaging Technology and Science, Volume 39, Issue 10, Page 1231-1251, October 2026.
Cellulosic microfibres were extracted from almond shells using organosolv, soda and kraft processes, and comprehensive physicochemical, surface, thermal and morphological characterisation demonstrated their strong potential as sustainable fillers for paper‐based packaging application. ABSTRACT This study develops pathways for the valorisation of almond

A review of empirical dam breach models

open access: yesRiver, Volume 5, Issue 3, Page 328-350, August 2026.
Abstract Dam breach modelling is central to flood risk assessment, yet the empirical models commonly used for estimating breach parameters display considerable variability and uncertainty. This review evaluates the performance of widely applied empirical dam breach models and identifies those that consistently show lower uncertainty, such as the ...

Multi‐Scale Engineering of Photonic Meta‐Structures With Emergent Optical Resonances via Colloidal Crystal Engineering With DNA and Microwell Templates

open access: yesSmall, Volume 22, Issue 58, 16 October 2026.
This work presents a bottom‐up strategy for forming meta‐structures built from DNA‐assembled nanoparticle superlattices, establishing a versatile platform for multiscale photonic materials design. Confinement stabilizes non‐equilibrium crystal habits and enables geometry and mode control independent of lattice symmetry.

Normalized ground state solutions for Kirchhoff equation with subcritical or critical perturbation

open access: yesElectronic Journal of Differential Equations
This article concerns the Kirchhoff equation with subcritical or critical perturbation. We establish the existence of normalized ground state solutions by using Pohozaev manifold and subcritical approximation methods.
