Water‐Borne Erosion of Reinforced Polymer Composites: Application to Shallow Offshore Marine Environment

open access: yesPolymer Composites, Volume 47, Issue 5, Page 4102-4126, 10 March 2026.
Comparison of experimental and model‐predicted erosion rates for carbon fibre‐reinforced polymer (CFRP) and glass fibre‐reinforced polymer (GFRP) under low‐velocity (2 m/s) and at varying angles and sand concentrations (0.0, 0.05, 0.4 g/L). The results demonstrate good agreement between experimental data and model predictions across different erosive ...

PAMPS PolyHIPEs: The Role of Shape, Porosity, and Sulfonate Group Density on Metal‐Ion Adsorption From Water

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 9, March 5, 2026.
This study demonstrates how pore architecture, shape, and sulfonate group density influence the adsorption of Zn2+, Fe3+, and Al3+ by PAMPS polyHIPEs. Beads and monoliths exhibit distinct transport behavior compared to commercial 77H resin. The results offer design guidelines for optimizing ion‐exchange polymers to improve performance in water ...

Spatiotemporal Dynamics of Plant–Soil–Enzyme Interactions in Intertidal Wetlands

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
This study reveals that during the exposure period in the Shengjin Lake intertidal wetland, the temporal gradient serves as the primary driving force for changes in the plant–soil–enzyme system, followed by alkaline phosphatase activity, nitrate nitrogen, and pH.

Hybrid ANN‐Based Modeling and Optimization of Drilling Performance in Basalt Fiber Composites

open access: yesEngineering Reports, Volume 8, Issue 3, March 2026.
This study optimizes drilling of woven basalt fiber–epoxy laminates using RSM and ANN–ABC models. Spindle speed, feed rate, and laminate thickness were analyzed for torque and delamination, identifying optimal conditions (1200 rpm, 0.1 mm/rev) for sustainable machining performance.

Seismic Enhancement of Masonry‐Infilled Substandard Reinforced Concrete Frames Using Lightweight Steel Exoskeleton

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 3, Page 603-623, March 2026.
ABSTRACT A significant portion of existing reinforced concrete (RC) structures in seismically active regions was constructed prior to the adoption of modern seismic design standards, leaving them highly susceptible to earthquake‐induced damage. The vulnerabilities of these structures, often exacerbated by material degradation, have been starkly ...

Plants and Insect Eggs: First Report of a Katydid Using a Fern as Host for Oviposition

open access: yesNew Zealand Journal of Botany, Volume 64, Issue 1, March 2026.
Ferns are the second most diverse lineage of vascular plants worldwide and are particularly abundant in tropical forests. However, the ecological significance of such remarkable diversity has been often underestimated. In this article, we report for the first time the observation of ferns, specifically Polytaenium cajenense (Desv.) Benedict ...
