In this paper, the tensile performance of 3D printed continuous fiber reinforced thermoplastic materials is investigated. Continuous carbon fiber and Polyethylene terephthalate glycol (PetG) are employed as reinforcement and matrix, respectively. Pure solid plastic infill, unidirectional fiber infill, and +45/-45 fiber infill patterns specimens are selected for printing and testing.

In this study, we evaluated and compared the effectiveness of four different protocols (D, MJ, MA, and S) for separating MPs from water of different types (brackish, marine, and river). Known combinations of MP particles (polyethylene (PE), polyethylene terephthalate (PET), polystyrene (PS) and polyvinyl chloride (PVC) with size ranging between 150 μm and 700 μm were spiked into water samples. Our results showed that the average recovery effectiveness of microplastics using four studied methods ranged from 53% to 86%.

In the present investigation, GNS have been prepared by an aqueous anodic exfoliation of pencil graphite in an acidic medium at different dc voltages (5 Ve12 V). The GNS prepared at optimum voltage were mixed with polyaniline (PANI) polymer and drop casted on an indium tin oxide (ITO)/Polyethylene terephthalate (PET) substrate to study the I-V characteristics and to measure the band gap of composites.

Microplastics with particle size less than 5 mm are becoming a raising global environmental crisis. These pollutants were found from the poles to the equator, in continental shelves, coasts and in the oceans, moreover, they have also been identified in the water columns, sediments and even in a variety of organisms.

The accumulation of microplastics (MPs) in the marine environment has become a global concern in recent years. MPs in oysters were considered as potential pollution in cultured farms in coastal areas. Accumulation of MPs in seafood may pose a threat to food safety, therefore it is important to investigate the abundance of MPs in bivalves to determine the potential risks of MPs to human health.

Polyester (polyethylene terephthalate) is one of the most widely used polymers in textiles. Despite all the advantages of this polymer, its low thermal resistance limits its use in filters and protective textiles. On the other hand, polyester nonwovens are used in many products as wipes, filters, and padding. The surface properties of polyester nonwovens are often not perfect for a specific application and need to be modified. Different ways, including coating, have been developed to modify their surface properties.

The aim of this research was to design an electrochemical immunosensor for determination of tumour necrosis factor receptor-associated protein-1(TRAP1) antigen, a heat shock protein linked to tumour necrosis factor. The indium-tin oxide covered polyethylene terephthalate (ITO-PET) electrode surface was cleaned and was prepared for the introduction of hydroxyl groups on its surface by using NH4 OH/H2 O2 /H2 O. As a silanization agent for covalent attachment of anti-TRAP1 on the surface of the ITO working electrode, 3-glycidoxypropyltrimethoxysilane (3-GOPS) was used.

Treatment of anterior cruciate ligament injuries commonly involves the use of polyethylene terephthalate (PET) artificial ligaments for reconstruction. However, the currently available methods require long fixation periods, thereby necessitating the development of alternative methods to accelerate the healing process between tendons and bones.

This paper presents an investigation on the performance of ZnO nanorod (ZNR)-based piezoelectric nanogenerators (PENGs). ZNRs on the ZnO seed layer coated double-sided flexible polyethylene terephthalate (PET) at different molar concentrations (0.01, 0.05 and 0.1 M) were synthesized by controlling the aspect ratio (length/diameter) of ZNRs, that are closely related to the piezoelectric output potential voltage using a simple hydrothermal method.
