As a result of the 2011 nuclear incident that occurred at the Fukushima Nuclear Power Plant, a large number of abandoned dogs and cats were left within the disaster zone. A small number of these animals were rescued and cared for at shelters. Prior to the dispersal of these animals to their owners or fosterers, we evaluated the degree of internal radiocesium contamination using a specially desi...

At ambient temperature, concrete exhibits excellent mechanical properties. However, understanding the behavior of under high-temperature conditions is crucial, especially for civil engineering applications during fire incidents. The growing use plastic-based products has led to a significant increase in polymer waste, posing environmental challenges. valorization this plastic waste form fibers ...

In this study, PET plastic waste, which is a type of polymer commonly used in the manufacture bottles, has been incorporated into concrete by partially replacing natural fine aggregate. An experimental study was conducted casting and testing 90 cylinders 54 cubes. A mixture designed aggregate substituted with waste (PW) at ratio 0%, 25%, 50%, various w/c ratios .40, .45, .55. Physical, mechanic...

In this work, reduced graphene oxide was successfully synthesized from Polyethylene terephthalate (PET) waste in the catalytic reactor. The effects of production variables such as temperature (375-450 C), weight bentonite catalyst (1-4%), and holding time (15-60 min) were investigated. physiochemical properties determined by employing various analytical techniques, like X-ray Diffraction (XRD),...

Poly(ethylene terephthalate) hydrolase (PETase) from Ideonella sakaiensis 201-F6 was expressed and purified Escherichia coli to hydrolyze poly(ethylene (PET) fibers waste for its monomers recycling. Hydrolysis carried out at pH 8 30 °C found be the optimal condition based on measured monomer mono(2-hydroxyethyl) terephthalate (MHET) terephthalic acid (TPA) concentrations after 24 h reaction. Th...

The recycling process is the best way to manage waste polymers. From an economic standpoint, more investigation needed of whole enhance competitiveness in these systems. A first step improved interaction and interfacial adhesion blends. Polyethylene (PE) polyethylene terephthalate (PET) are incompatible polymers, so their blends general have poor properties. Compatibilization thus a necessary o...
