Status of the art of the Italian micromegas for the upgrade of the ATLAS detector
No full textLarge-size multilayer resistive micromegas detectors will be employed for the muon spectrometer upgrade of the ATLAS experiment at CERN, the new small wheel project. The status of the art of the micromegas construction in Italy will be reviewed, along with the performance studied on the first full size module

Coatings from natural macromolecules, with gas barrier properties tailored in situ, and related preparation method
No full textThe invention concerns lake compositions based on natural macromolecules (gelatin, chitosan, pectine etc.) with possible additions of vinyl polymers, metal-alcoxides etc., characterized by a barrier effect modulated in situ, in particular as a function of the relative humidity in the exterior ambient
Biobased coatings as a solution to improve the overall performances of plastic films
No full textThe present research dealt with evaluating barrier, friction and optical properties of three different plastic films after deposition of a gelatin-based bio-coating. The composite films showed improved barrier properties against oxygen and UV radiation. Static and kinetic coefficients of friction were significantly decreased both in the film-to-film and in the film-to-metal tests, leading to a desirable value for many applications. However, bio-coated films showed lower optical performances in terms of transparency and haze. Not significant differences were observed as far as the water vapour permeability is concerned. The obtained data suggest that the lipid-protein coating tested in this study, in spite of its great potential for enhancing some characteristics of plastic packaging films, still exhibits negative aspects which necessitate further improvemen
