Polyethylene terephthalate (PET) and polylactic acid (PLA) bottles were tested to evaluate radon loss from water during 15 days of storage. PET bottles (lower surface/volume-ratio vials) lost 0.4e7.1% of initial radon, whereas PLA bottles lost 3.7% of it. PET bottles with volume of 0.5 L, lower surface/weight ratio, and hence higher thickness display proportionally reduced radon loss. Correctio...

The present work aims at evaluating temperature dependency of product evolution from pyrolysis of binary mixtures of low density polyethylene (LDPE), and polyethylene terephthalate (PET). Product distribution studies have been reported for three different mixture compositions (20:80, 50:50, and 80:20) in the temperature range of 300-600oC, for a wide range of hydrocarbon products (C5-C44) and t...

Azoisobutylnitrile (AIBN) initiator was used in the treatment of most widely used domestic plastics in lieu of catalysts. The pyrolysis of low-density polyethylene (LDPE), high-density polyethylene (HDPE), polypropylene (PP), poly-ethylene terephthalate (PET) and polystyrene (PS) plastics with azoisobutylnitrile was carried out individually under nitrogen atmosphere. A series of single (plastic...

Bioremediation. The discovery of MG8, an efficient polyethylene terephthalate (PET) hydrolase enzyme from the human saliva metagenome, is reported by Worawan Bhanthumnavin, Chayasith Uttamapinant et al. in their Research Article (e202203061). Aside its plastic degradation capability, MG8 was further engineered via genetic code expansion into a covalent binder PET and can be used to attach prote...

This paper reports the strength behaviour of concrete containing three types of recycled polyethylene terephthalate (PET) aggregate. Results are also analysed to determine the PET-aggregate’s effect on the relationship between the flexural and splitting tensile strengths and compressive strength and to know whether the relationships between compressive strength and other strength characteristic...

• Increased quality With sales of 137 million Euros in 2011, Armor is one of the leaders in producing inked ribbon used in thermal transfer printing for product identification and other applications. Ribbon is produced by applying ink to polyethylene terephthalate (PET) film in a web coating process in which the speed, tension and position of the web and other variables must be closely controll...

Bulk samples and thin sections of polyethylene terephthalate (PET) and polyimide (PI) were irradiated with Se and Pb ions of 11.4 MeV/u at the UNILAC. The creation of latent tracks and related structural changes were studied by means of transmission electron microscopy (TEM) using a 200 kV Philips CM200-UTW microscope (point resolution 0.17 nm). Due to relatively similar electron densities with...

A self-powered ultraviolet (UV) photodetector (PD) based on p-NiO and n-ZnO was fabricated using low-temperature sputtering technique on indium doped tin oxide (ITO) coated plastic polyethylene terephthalate (PET) substrates. The p-n heterojunction showed very fast temporal photoresponse with excellent quantum efficiency of over 63% under UV illumination at an applied reverse bias of 1.2 V. The...
