A novel meta-regression method, PET-PEESE, predicts and explains recent high-profile failures to replicate in psychology. The central purpose of this paper is to identify the limitations of PETPEESE for application to social/personality psychology. Using typical conditions found in social/personality research, our simulations identify three areas of concern. PET-PEESE performs poorly in researc...

Cutinases have shown potential for hydrolysis of the recalcitrant synthetic polymer polyethylene terephthalate (PET). We have shown previously that the rate of this hydrolysis can be enhanced by the addition of hydrophobins, small fungal proteins that can alter the physicochemical properties of surfaces. Here we have investigated whether the PET-hydrolyzing activity of a bacterial cutinase from...

We examined whether environmentally relevant concentrations of different types of microplastics, with or without PCBs, directly affect freshwater prey and indirectly affect their predators. Asian clams (Corbicula fluminea) were exposed to environmentally relevant concentrations of polyethylene terephthalate (PET), polyethylene, polyvinylchloride (PVC) or polystyrene with and without polychlorin...

Interaction of menthol with polyethylene terephthalate bottles during storage time was tested at three different temperatures. Menthol is a mint flavor agent added to yogurt drinks in Iran and is considered as a factor affecting consumer acceptance. Absorption of menthol to packaging material could cause a loss of quality in the final product due to diminished flavor intensity. Tests were done ...

Simultaneous thermogravimetry-mass spectrometry studies of a pyrolytic decomposition of mixtures of different plastic wastes/coking coal were carried out. The investigation was performed at temperatures up to 1000oC in a helium atmosphere under dynamic conditions at a heating rate of 25 oC/min. Five thermoplastics, commonly found in municipal wastes: low density polyethylene (LDPE), high densit...

This study is concerned with pH solution detection using 2 × 4 flexible sensor array based on a plastic polyethylene terephthalate (PET) substrate that is coated a conductive layer and a ruthenium dioxide (RuO2) sensitive membrane with the technologies of screen-printing and RF sputtering. For data analysis, we also prepared a dynamic measurement system for acquiring the response voltage and an...

In the field of construction, sustainable building materials are currently undergoing a process of technological development. This study aims to contribute to understanding the behavior of the fundamental properties of concretes prepared with recycled coarse aggregates that incorporate a polyethylene terephthalate (PET)-based additive in their matrix (produced by synthesis and glycolysis of rec...

Nowadays polymer nanocomposites have introduced as a new class of food packaging materials due to their enhanced mechanical, thermal, and barrier properties. In this study PET nano composites were prepared by melt blending of poly (ethylene terephthalate) pellets and mica nanoparticles. The morphology of PET/mica nanocomposites was characterized by X-ray diffraction and transmission electron mi...

The scientific definition of polyethylene terephthalate (PET) changed for polyester in the common language. It was first manufactured 1928 and production fibre version started 1941. Nowadays, 70% artificial textile raw materials are fibres a significant amount plastic waste is generated at end life cycle clothing other products. injection moulding process introduced 1970s made it possible to de...

In this study, the prototype of a thermal roller imprint lithography (RIL) system was developed and applied to RIL tests to evaluate its feasibility for the large area replication of an optical micro device. The developed system adapts an automatic stamp releasing mechanism and has the capacity to replicate ultra-precision structures on an area of 100mm×100mm at the scanning speed range of 0.1–...
