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

open access: yesJournal of Applied Polymer Science, EarlyView.
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.

Redox‐Targeting Reactions of Viologen‐Based Shuttles and Polymers Translated From Nonaqueous to Aqueous Electrolyte

open access: yesChemistry – A European Journal, EarlyView.
. ABSTRACT Redox‐targeting flow batteries (RTFBs) present an attractive strategy for enhancing the energy density of conventional redox flow batteries (RFBs) by integrating heterogeneous energy storage materials as capacity boosters. However, nearly all RTFB systems have been developed with nonaqueous redox chemistries, while capacity boosters in ...

Synthesis and Optical Properties of Diboron Complexes of 1,4‐Anthraquinone Derivatives

open access: yesChemistry – A European Journal, EarlyView.
1,4‐Diboron complexes exhibit near‐infrared fluorescence, in contrast to non‐emissive 1,5‐diboron analogues. Fluorescence quantum yields decrease with increasing electron‐donating substituents, attributed to enhanced nonradiative decay via intramolecular PeT.

Organelle‐Resolved Tetrazine‐trans‐Cyclooctene Click Chemistry for Cargo Delivery and Release

open access: yesChemistry – A European Journal, EarlyView.
Bioorthogonal click chemistry tools provide a means for specific intracellular conjugation of molecules. In this study, we used reactive tetrazine (Tz) and TCO moieties for labeling of organelles and organelle‐specific delivery and activation of doxorubicin prodrugs.
