Liquid Chromatography Coupled With High‐Resolution Mass Spectrometry Profiling of Metabolites in Cassia alata Flower Extracts and Their DPPH Free Radical Scavenging Activity

Analytical Science Advances, Volume 7, Issue 2, December 2026.
ABSTRACT Cassia alata flowers remain phytochemically under‐characterized relative to the leaves. However, floral tissues can harbour distinct and, in some species, more abundant phenolic and flavonoid profiles, representing an unexploited source of antioxidant phytochemicals with potential functional‐food and nutraceutical relevance. Also, Cassia alata

Recyclable and Degradable Covalent Adaptable Polymer Networks (CANs) Based on Dynamic Thiol–Yne Reactions

Journal of Applied Polymer Science, Volume 143, Issue 44, November 20, 2026.
Covalent adaptable networks based on activated alkynes, that is, alkynones, and multifunctional thiols (three and tetrafunctional) are tested in two different recycling strategies: (i) mechanical recycling based on their vitrimeric properties and (ii) chemical recycling based on the reversible thiol addition on the vinylene compound.

Partially Biobased Polyurethanes With Reversibly Crosslinkable Furan Units Toward Recyclable Thermosetting Textile Fibres

Chemistry – A European Journal, Volume 32, Issue 41, 3 November 2026.
A molecular design strategy combines lignin‐derived aromatic units, sugar‐derived furan groups, and flexible glycol segments to create wet‐spinnable polyurethanes. Thermally reversible Diels–Alder crosslinking chemistry enables formation of crosslinked thermosetting fibers, repeated de‐crosslinking/re‐crosslinking cycles, and tunable fiber properties ...
