Greener routes for recycling of polyethylene terephthalate

Routes to greener plastics

How to hide a dimension from view Compacted dimensions are essential ingredients of advanced string theories; the extra dimensions used to describe the world are hidden from view, or compacted. Pendry et al. used concepts of transformation optics, in which metamaterials are designed to produce specific optical properties, to show theoretically that compacted dimensions could be possible in plas...

Biocatalysis as a green route for recycling the recalcitrant plastic polyethylene terephthalate

Biocatalysis can enable a closed-loop recycling of post-consumer PET waste.

Performance evaluation of cutting fluids additives developed from recycling of polyethylene terephthalate

Metalworking-fluids (MWFs) perform essential functions to metal-products manufacturing industry. MWFs also have inherent environmental and health liabilities associated to industry. These liabilities viewed as opportunity to reevaluate the functionality of MWFs and improve profitability of operations. Several problems appeared in using of MWFs including biodegradation of constituents. The objec...

Immobilization of silver nanoparticles on polyethylene terephthalate

Two different procedures of grafting with silver nanoparticles (AgNP) of polyethylene terephthalate (PET), activated by plasma treatment, are studied. In the first procedure, the PET foil was grafted with biphenyl-4,4'-dithiol and subsequently with silver nanoparticles. In the second one, the PET foil was grafted with silver nanoparticles previously coated with the same dithiol. X-ray photoelec...
