Molecular oxygen-assisted in defect-rich ZnO for catalytic depolymerization of polyethylene terephthalate

iScience, 2023
Summary: Polyethylene terephthalate (PET) is the most produced polyester plastic; its waste has a disruptive impact on the environment and ecosystem. Here, we report a catalytic depolymerization of PET into bis(2-hydroxyethyl) terephthalate (BHET) using ...

In silico Characterization of Poly (ethylene) Terephthalate (PET): Degrading Enzymes from Rhizobacter sp. for Enzymatic Degradation Mechanisms

Journal of Tropical Life Science
Dienelactone hydrolase (DHL) from Rhizobacter sp. is an enzyme from the β‐ketoadipate pathway that belongs to the α/β hydrolase family. It involves the conversion of chloroaromatics, such as nitrophenols and hydrocarbons, into harmless metabolites.

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

Advanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,
