In‐Process Melt Separation of Depolymerized PET in PET/PE Blends for Upcycling via Twin‐Screw Extrusion

open access: yesPolymer Engineering &Science, EarlyView.
This work aims to depolymerize PET in PET/LLDPE blends via twin‐screw extrusion to allow low‐Mw PET to be extracted and separated. The separated PET is made into BHET and then sold to create virgin PET. LLDPE will be cracked into low‐Mw products that can be utilized as various products.

Compatibilization Mechanisms of Telechelic Polyethylene Reactive Additives in Polyethylene Terephthalate/Polyethylene Blends

open access: yesJournal of Polymer Science, EarlyView.
A deeper understanding of reactive blend compatibilization using hydroxy telechelic polyethylene additives in blends of glycol‐modified polyethylene terephthalate and polyethylene is developed. Preformation of copolymer during reactive mixing is key for successful compatibilization of this system at lower mixing temperatures. ABSTRACT Imperfect sorting

Polyethylene terephthalate capacitor film doping: Selection of conditions

open access: yesУчёные записки Казанского университета: Серия Естественные науки
Polyethylene terephthalate (PET) film has good dielectric properties but high radiation-induced conductivity, which can be reduced by doping commercially available electrical insulation films with small electron-trapping molecules.

Polyesterase activity and thermostability of carboxylesterases from Thermoleophilum album YS‐3

open access: yesThe 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

Pulsed electrosynthesis of glycolic acid through polyethylene terephthalate upcycling over a mesoporous PdCu catalyst

open access: yesNature Communications
Electrocatalytic upcycling of polyethylene terephthalate (PET) plastics offers a promising and sustainable route that not only addresses serious waste pollution but also produces high value-added chemicals. Despite some important achievements, their activity and selectivity have been slower than needed. In this work, pulsed electrocatalysis is employed

Conspecific cueing or cooperative feeding?—Foraging stable flies are visually attracted to conspecific flies

open access: yesMedical and Veterinary Entomology, EarlyView.
In two‐choice laboratory bioassays, food‐deprived and CO2‐stimulated stable flies were offered paired landing platforms that were baited or not (control) with conspecific flies. The presence of conspecifics prompted the attraction and landing of foraging stable flies.
