“…According to previous studies, ,, PVC was assumed to have decreasing chlorine (C–Cl) vibration peaks at 635 and 697 cm –1 , a declining C–H stretching mode at 2912 cm –1 , as well as new peaks at 1510 or 1597 cm –1 assigned to a CC stretching vibration , as a result of dehydrochlorination . However, our results showed no significant linear decrease or increase in peak intensities in Raman spectra over the exposure time.…”

Microplastics (MPs) are one of the most abundant and widespread anthropogenic pollutants worldwide. In addition to the global spread and threats of plastic to native species by carrying toxic substances, its slow degradation rate and resulting long retention time in the environment constitute a problem that is still poorly understood. In this study, five of the most manufactured plastic types were weathered under simulated beach conditions for 18 months in freshwater, brackish water, and seawater. Those included polyethylene (PE), polypropylene (PP), polystyrene (PS), polyethylene terephthalate (PET), and polyvinyl chloride (PVC). PP was the first polymer type that fragmented after 9 months of weathering and influenced the pH of the surrounding water. Molecular surface changes were detected for all polymers, just after the first week. Hydroxyl bonds were one of the first groups incorporated into the polymers, weakening 2–3 weeks later. Carbonyl groups were also measured early, but with significantly different developments with time between the polymer types. Differences in degradation rates were proven between the water media, with the fastest degradation in seawater compared to brackish water and freshwater for PE and PP. These results are consistent with previous findings on MPs aged under environmental conditions and provide initial long-term observations of MP degradation pathways under simulated environmental conditions. These findings are valuable for assessing the fate and hazards of MPs in aquatic systems.

“…Indeed, ion beam irradiations have been utilized positively for the synthesis of novel exotic phases, surface and interface modifications as well as characterizations of materials depending upon the energy of the ions [15][16][17][18]. These modifications improve the structural, electrical and optical properties of the films which make reliable to these ion modified substrates in various optoelectronic device applications [19][20][21].…”

The effects of 10 MeV Al4+ ions irradiation on structural, surface morphological, optical and electrical properties of fluorine-doped tin oxide (FTO) substrates are presented for solar cell applications. The ions irradiation changes the surface morphology, average roughness, interface width, roughness exponent, and several other fractal parameters of the FTO surfaces. The UV–visible transmittance measurement shows an enhancement of transmittance in the ions irradiated substrates up to 95%. The electrical properties such as mobility, work-function, sheet resistance, and resistivity are also modified due to ions irradiation. In order to have functional applications of these ions irradiated substrates, we fabricated organic solar cells on these ions irradiated and pristine FTO substrates. The device performances are significantly improved for the case of ions irradiated FTO substrate in comparison to the pristine one. Thus, better device performance due to effective changes in physical properties suggests that the ions irradiated FTO substrates can be used as better electrodes for organic and hybrid photovoltaic device applications.
