Review ArticleOpen accessIn the keywordsStructural Colour from Optical Phenomena Caused by Interference with a Thin or Multilayer Film, Photonic Nanocrystals, Light Scattering and Diffraction Grating EffectRelly Victoria Petrescu, Raffaella Aversa, Antonio ApicellaThe paper presents the Ion Plating Plasma Assisted technology that is applied in the area of surface functionalization with the purpose of preserving the structural colour and relics. The interferometric structural colours applied on titanium surfaces were used and tested together with nano-transparent and at the same time achromatic films on the very old ceramic artifact. In order to test … …Journal of Aircraft and Spacecraft Technology, Vol. 4, Issue 1 · 13 Aug 2020 · 6,503 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFrom Structural Colors to Super-Hydrophobicity and Achromatic Transparent Protective Coatings: Ion Plating Plasma Assisted TiO2 and SiO2 Nano-Film DepositionRaffaella Aversa, Valeria Perrotta, Relly Victoria V. Petrescu et al.The implementation of the Ion Plating Plasma Assisted technology in the area of surface functionalization for structural color and relic preservation applications is presented. Interferometric structural colors on irregular bumped Titanium surfaces and transparent and achromatic nano films on ancient ceramic artifact have been investigated. Titanium metal and ceramic supports have been utilized for the surface functionalization tests: A metallic … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 24 Nov 2016 · 8,459 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Characterization of Al Bond Pad Surface Treatment in Electroless Nickel Immersion Gold (ENIG) DepositionM.K. Md Arshad, A. Jalar, I. Ahmad, G. OmarThis study reports a number of experiments that were designed to characterize aluminum bond pad surfaces prior to electroless nickel immersion gold (ENIG). In the ENIG process, aluminum bond pads need special treatment to achieve successful nickel deposition and provide reliable interconnection of under bump metallurgy in advanced packaging. During this treatment process, the aluminum pad was cleaned, activated and … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,722 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordThermoelectric and Optical Properties of Advanced Thermoelectric Devices from Different Multilayer Thin FilmsMebougna Drabo, Satilmis BudakThermoelectric devices were prepared using different multilayered thin film structures in the order of Ge/Si+Ge, Si+Ge, Si, Sb+Ge, Ge and SiO2/SiO2+Ge by DC/RF Magnetron Sputtering. The thickness of the deposited thin films were measured using Filmetrics UV thickness measurement system. The prepared thermoelectric devices have been modified with 5 MeV Si ions bombardments at the different fluences (doses) using Pelletron … …American Journal of Applied Sciences, Vol. 16, Issue 8 · 29 Aug 2019 · 8,113 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordProcessability of Bulk Metallic GlassesRaffaella Aversa, Daniela Parcesepe, Relly Victoria V. Petrescu et al.Microfluidic Shear Flow Instabilities in Injection Molded Glassy Metal are investigated. The formation of microfluidic shear flows instabilities involving the presence of different viscosities fluids has been observed in injection molded Bulk Metallic Glasses. The complex rheology of injection molded metastable glassy metal, which has been hypothesized to induce selective clustering of atoms of different steric hindrance, is discussed. Smaller … …American Journal of Applied Sciences, Vol. 14, Issue 2 · 15 Feb 2017 · 7,487 accessesView PDF Cite
