Depolymerization mechanisms and closed-loop assessment in polyester waste recycling
Nature CommunicationsAlcoholysis of poly(ethylene terephthalate) (PET) waste to produce monomers, including methanolysis to yield dimethyl terephthalate (DMT) and glycolysis to generate bis-2-hydroxyethyl terephthalate (BHET), is a promising strategy in PET waste management.

, 1997 The extent of transesterification reaction, intrinsic viscosity, weight-average molecular weight and hydrodynamic radius of poly(ethylene 2,6-naphthalate) (PEN)/poly(ethylene terephthalate) (PET) (50/50, w/w) blend were measured as a function of reaction

The plasticisation model of dye diffusion: Part 6
Coloration Technology, EarlyView.Abstract Previously published data reported for the temperature dependency of the exhaustion of a mordant dye and acid dye, as well as both the exhaustion and fixation of a reactive dye and adsorption of a direct dye, on three different types of wool substrate, over a diverse range of dyeing temperatures and conditions, were re‐evaluated using the ...

The plasticisation model of dye diffusion: Part 8
Coloration Technology, EarlyView.Abstract Re‐evaluation using the Williams–Landel–Ferry equation, of exhaustion/rate of dyeing/fixation data previously reported for and acid dye, natural dye and two reactive dyes on three different types of silk substrate revealed that thermally activated dye diffusivity is governed by the thermally regulated structural relaxation times of the ...

Polyesterase activity and thermostability of carboxylesterases from Thermoleophilum album YS‐3
The FEBS Journal, EarlyView.Three novel α/β‐hydrolases from thermophilic bacterium Thermoleophilum album display carboxylesterase and polyesterase activity. These enzymes hydrolyse PET, PLA and PCL both at high and moderate temperatures. TA21 shows superior activity, efficiently converting MHET to terephthalic acid. Structural features underlying substrate binding highlight their

, 2009 PhDComposites are normally composed of two distinct phases: reinforcement and matrix. In recent years, a new class of “self-reinforced” polymer composites or “all-polymer” composites, which are based on similar or identical materials for both ...

ChemSusChem, Volume 19, Issue 12, 26 June 2026.A solvent‐free mechanochemical process to upcycle PVDF waste into sodium aluminium fluorides, which are essential for aluminium production, was developed. By ball milling PVDF with AlCl3 and NaCl, the polymer degrades into chiolite and graphitic materials. Subsequent calcination then yields cryolite.
