Analysis of the hydrogen permeation properties of TiN-TiC bilayers deposited on martensitic stainless steel
Riccardo Checchetto,M. Bonelli,Luigi M. Gratton,Antonio Miotello,A. Sabbioni,L. Guzman,Y. Horino,G. Benamati +7 more
TL;DR: In this article, the efficiency of TiN-TiC bilayer coatings, deposited by ion-beam-assisted deposition on martensitic steel, as a hydrogen permeation barrier was investigated by a gas phase method; the hydrogen permeability in the bilayers is very low, at least 104 times lower than in the steel substrate in the temperature interval 470-570 K. Possible physical mechanisms, responsible for the reduced permeability of the ceramic bilayers, were discussed.

Structure and mechanical properties of low stress tetrahedral amorphous carbon films prepared by pulsed laser deposition
M. Bonelli,Andrea C. Ferrari,Antonella Fioravanti,A. Li Bassi,Antonio Miotello,Paolo Maria Ossi +5 more
TL;DR: Tetrahedral amorphous carbon films have been produced by pulsed laser deposition, at a wavelength of 248 nm, ablating highly oriented pyrolytic graphite at room temperature, in a 10-2 Pa vacuum, at fluences ranging between 0.5 and 35 Jcm-2 as mentioned in this paper.

Chemical and compositional changes induced by N + implantation in amorphous SiC films
Nadhira Laidani,M. Bonelli,Antonio Miotello,L. Guzman,Lucia Calliari,M. Elena,Renzo Bertoncello,Antonella Glisenti,R. Capelletti,Paolo Maria Ossi +9 more
TL;DR: In this article, the effects of 30 keV N+ implantation in amorphous silicon carbide films deposited on silicon substrates by rf sputtering over a fluence range of 1×1016-2×1017 ions (cm−2) were studied by means of x-ray photoelectron spectroscopy (XPS), Auger electron spectrography (AES), and infrared (IR) absorption techniques.

Pulsed laser deposition of diamondlike carbon films on polycarbonate
TL;DR: In this article, diamond-like carbon films have been deposited on polycarbonate by pulsed laser deposition technique by irradiating highly oriented pyrolytic graphite with high-energy excimer laser pulses (248 nm wavelength, 20 ns duration, and up to 37 J/cm2 energy density).

Pulsed laser deposition apparatus for applied research
TL;DR: In this article, the authors describe an apparatus for pulsed laser deposition of thin solid films that they have developed in their laboratories of Trento University, which is original for many of its adopted technical solutions: the substrate-manipulator mechanism possesses four degrees of freedom, x, y and z translation and a rotation, which permits one to treat samples with nonplanar geometry.
