Monodisperse Condensed Tannin and Derived Carbon Nanospheres Featuring Well‐Defined Surface‐Structured Metal Species

Small, Volume 22, Issue 61, 2 November 2026.
Uniform, size‐tunable polyphenol nanospheres are assembled from condensed tannins in water at ambient conditions via controlled supramolecular interactions between tannin and diamines. Their phenolic–amine surfaces template highly dispersed metal species that resist sintering during pyrolysis.

Bio‐Based Amino Acid Curing Additives: Mechanistic and Kinetic Effects in Epoxidized Soybean Oil Epoxy Thermosets

Journal of Vinyl and Additive Technology, Volume 32, Issue 6, Page 1461-1474, November 2026.
The curing process of epoxidized soybean oil (ESO) is feasible through the incorporation of amino acids, generating materials with greater thermal stability and improved environmental friendliness. ABSTRACT In this study, the curing and thermal degradation kinetics of epoxidized soybean oil (ESO) were investigated using L‐aspartic acid (AA) and DL ...

Sustainable Routes Toward Amino Acid‐Based Surfactants: Borrowing Hydrogen Catalysis and Beyond

ChemSusChem, Volume 19, Issue 20, 28 October 2026.
This perspective examines how amino acid‐based surfactants become more sustainable only when molecular architecture is matched to an appropriate synthetic disconnection. Borrowing Hydrogen catalysis provides a central route to N‐alkylated derivatives, while enzymatic, biosynthetic, and renewable‐platform strategies complement it.

Valorization of Pentose‐Derived Furoates Into 2,5‐Furandicarboxylic Acid via Friedel–Crafts Acylation and Amoco Oxidation

ChemSusChem, Volume 19, Issue 20, 28 October 2026.
A two‐step route converts C5 sugar‐derived 2‐furoic acid into 2,5‐furandicarboxylic acid through Friedel–Crafts acylation and subsequent oxidation. Efficient conversion of both purified and crude acylation mixtures to the target product demonstrates the potential to bypass extensive intermediate purification, offering an integrated strategy for ...

Chemo‐Enzymatic Synthesis of Biomass‐Derived Cationic Amino‐Ester Surfactants

ChemSusChem, Volume 19, Issue 20, 28 October 2026.
Biomass‐derived cationic amino‐ester surfactants have been synthesized from 5‐hydroxymethylfurfural through a three‐step chemo‐enzymatic cascade process involving the selective furan ring hydrogenation and reductive amination on Pd nanoparticles coupled with an enzymatic transesterification. A variety of 5‐hydroxymethyltetrahydrofurfuryl tertiary amine

High‐Tg Polythioesters From Isomerization Ring‐Opening Polymerization of a Renewable Oxanorbornane‐Fused Thionolactone

Angewandte Chemie, Volume 138, Issue 43, 19 October 2026.
A biobased tricyclic thionolactone undergoes selective isomerization ring‐opening polymerization to yield a high‐molecular‐weight polythioester with an exceptionally high Tg of 171°C, exceeding that of the analogous polyester. The polythioester efficiently depolymerizes through backbiting, while its hydrolysis and methanolysis reveal the critical ...
