Graphene oxidation and reduction in medium vacuum by an UV lamp at 365 nm wavelength

The time-dependent graphene oxide (GO) reduction in medium vacuum under ultraviolet (UV) irradiation at 365 nm has been investigated. We found that GO exposed to UV at room temperature and at a vacuum of about 10−1 mbar shows a notable oxidation for irradiation times up to about 60 min followed by a successive reduction up to 210 min. Characterization measurements have been performed mainly using the Attenuated Total Reflectance (ATR) Fourier Transform Infrared (FTIR) and Raman spectroscopies...

Polyvinylalcohol Composite Filled with Carbon Dots Produced by Laser Ablation in Liquids

Carbon dots (CDs), owing to their excellent photoluminescent features, have been extensively studied for physics preparation methods and for biomedical and optoelectronic device applications. The assessment of the applicability of CDs in the production of luminescent polymeric composites used in LEDs, displays, sensors, and wearable devices is being pursued. The present study reports on an original, environmentally friendly, and low-cost route for the production of carbon dots with an averag...

High nitrogen and argon diffusion in cyclic olefin copolymer foil versus temperature

Measurements of nitrogen and argon diffusion coefficient in cyclic olefin copolymer (COC) have been performed at different temperatures ranging between 21 & DEG;C and 101 & DEG;C. Optical transparent COC foils have been prepared with 10 & mu;m thickness and total surface of about 25 cm2. The foils have exhibited high purity in composition. The morphology of the COC surface has been investigated by Scanning Electron and Atomic Force Microscopies. The room temperature measured diffusion coeffic...

Nanoparticles produced by laser ablation in organic solvent for polylactic acid-based polymer

Recently packing technology has been rising as a new domain for the application of nanoparticles. Herein the synthesis of polylactic acid (PLA) foils decorated with nanoparticles is investigated. The gold nanoparticles (Au NPs) can play a major role in reducing microbial load in aliment and to improve the food packaging quality. Au NPs have been fabricated by laser ablation in an organic liquid and then the PLA, with Au NP composites, has been manufactured through the drop-casting method. The...

Mass spectrometry of graphene oxide thermal reduction in vacuum

Foils of graphene oxide (GO) prepared by micrometric graphene oxide platelets dispersed in water at low concentrations were physically investigated during their thermal reduction in a vacuum. The water, the carbon dioxide and the functional groups of oxygen, degassed during the thermal treatment, were monitored for the first time with a quadrupole mass spectrometer as a function of the foil temperature. Fourier transform infrared (FTIR) spectroscopy and energy dispersive X-rays (EDX) analyses...
