Marine debris (MDs) produces a wide variety of negative environmental, economic, safety, health and cultural impacts. Most marine litter has a very low decomposition rate (plastics), leading to a gradual accumulation in the coastal and marine environment. Characterization of the MDs has been done in terms of their pollutant content: PAHs, ClBzs, ClPhs, BrPhs, PCDD/Fs and PCBs. The results show ...

A method for the large-scale fabrication of patterned organic nanowire (NW) arrays is demonstrated by the use of laser interference patterning (LIP) in conjunction with inductively coupled plasma (ICP) etching. The NW arrays can be fabricated after a short ICP etching of periodic patterns produced through LIP. Arrays of NWs have been fabricated in UV-absorbent polymers, such as PET (polyethylen...

Optoelectronic properties of CVD graphene are characterized over a wide frequency range: THz, IR, visible and near-UV. We used Raman spectroscopy to characterize the synthesized graphene films. All graphene layers were deposited on various substrates, some ones transparent or flexible, such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), quartz and silicon. Transmission Ter...

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),...

PET (Polyethylene Terephthalate) material is widely used for several industries, especially the electronics industry. This study conducted a design and simulation manufacture of cases smartphones using plastic injection machines manufacturing process. On results, it found that filling process, temperature pressure have similarities, namely distribution starting from center point to end casing d...

In this study, 8 novel pyrazole disperse dyes which were synthesized in our previous work [1] applied to polyethylene terephthalate (PET), poly (lactic acid) (PLA) and polyamide 6.6 (PA 6.6) fiber fabrics their colorimetric fastness properties evaluated. The measured a*, b* hue angle (ho) values of all dyed exhibited yellow, orange red colour shades. Quite high strength (K/S) particularly for c...

The publication focuses on the testing of tensile strength samples produced by Fused Filament Fabrication additive manufacturing technology. Three materials rPLA, rPETG and rPET were tested. These are recycled PLA (Polylactic Acid), PETG (Polyethylene Terephthalate Glucol) PET Terephthalate). used to create for according ASTM D638. In addition materials, methodology was also tested using sets s...
