Polyurethane Depolymerization With Alkyl, Aryl, and Mixed Carbonates
ChemSusChem, Volume 19, Issue 11, 15 June 2026.The depolymerization of polyurethane foams strongly depends on carbonate structure. Aryl carbonates improve hard‐segment solubility but generate side products. Alkyl carbonates give cleaner products yet suffer from limited hard‐block solubility and require anisole as a cosolvent. Mixed carbonate systems balance these effects, improving solubility while

The ladder-shaped polyether toxin gambierol anchors the gating machinery of Kv3.1 channels in the resting state [PDF]
, 2013 : Voltage-gated potassium (Kv) and sodium (Nav) channels are key determinants of cellular excitability and serve as targets of neurotoxins. Most marine ciguatoxins potentiate Nav channels and cause ciguatera seafood poisoning.
