Separation of Polyamide 66 From Blends With Wool Through Selective Dissolution: Implications of the Presence of Dyes

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 33, September 5, 2026.
The study assesses dye impacts on PA66/wool recycling via selective PA66 dissolution in calcium chloride–ethanol–water and water reprecipitation. Acid dyes migrate into solvent, yielding color‐free, melt‐spinnable PA66 and reusable wool. Metal‐complex dyes remain, altering PA66 melt viscosity and requiring extraction or repurposing.

A TREK‐1/AQP4/TRPA1/BDNF Signaling Axis Is Associated With Astrocytic Volume Transients, Synaptic Plasticity, and Spatial Memory

open access: yesGlia, Volume 74, Issue 9, September 2026.
Astrocytic TREK‐1‐dependent volume transients contribute to hippocampal synaptic plasticity and memory formation. TRPA1‐mediated astrocytic calcium signaling is required for long‐term potentiation, while astrocytic BDNF is necessary and sufficient to support sustained synaptic plasticity.
