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 PDFCite
EditorialOpen accessIn the abstractThe Proton Radius PuzzleG. M. HuberOccasionally,“revolutions” are caused in physics when new measurement techniques becomeavailable and cause us to rethink what we thought we knew. This has recently happenedin the field of proton structure physics, where researchers have had to revisitfundamental assumptions used in their determinations of the proton's meanelectric charge radius. Until 2010, ourknowledge of the proton's electric charge radius came exclusively fromelectron-proton interactions. … …Physics International, Vol. 6, Issue 1 · 12 Sep 2015 · 8,321 accessesView PDFCite
Research ArticleOpen accessIn the abstractDEEP TRAPS SPECTRA IN UNDOPED GAN FILMS GROWN BY HYDRIDE VAPOR PHASE EPITAXY UNDER VARIOUS CONDITIONSA. Y. Polyakov, N. B. Smirnov, A. V. Govorkov et al.Decreasing the residual donors density and deep traps spectra densities in undoped GaN films grown by Hydride Vapor Phase Epitaxy (HVPE) is very important for promoting the use of such material in high-voltage/high-power rectifiers, radiation detectors. In this study we studied the effects of changing the growth temperature of undoped HVPE GaN films on these properties. The two groups of … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 30 Sep 2014 · 6,901 accessesView PDFCite
Research ArticleOpen accessIn the abstractModification of Carbon Steel by Laser Surface Melting: Part II: Effect of Laser Beam Power on Microstructural Features and Surface HardnessHashem F. El-Labban, M. Abdelaziz, Essam R.I. MahmoudThe surface hardness has an important effect on the wear resistance of different materials. The present study aims to improve the surface hardness of carbon steel through the application of laser surface melting with suitable conditions. The laser beam power and travelling speed are the main factors that affect the properties of the treated zone. In this study, three different … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 4 · 30 Jan 2014 · 7,208 accessesView PDFCite
Research ArticleOpen accessIn the abstractModification of Carbon Steel by Laser Surface Melting: Part I: Effect of Laser Beam Travelling Speed on Microstructural Features and Surface HardnessHashem F. El-Labban, M. Abdelaziz, Essam R.I. MahmoudThe present study aims to improve the surface hardness of carbon steel by application of laser surface melting of effective conditions. The travelling speed of laser beam during this treatment is one of the important treatment conditions. This study aims to investigate the effect of laser surface melting with different beam speeds on macro and microstructure as well as the … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 4 · 2 Jan 2014 · 7,400 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHE STRUCTURE AND MECHANICAL PROPERTIES OF ALUMINA FILM PREPARED BY RF DIODE SPUTTERINGH. Panitchakan, P. LimsuwanAlumina (Al2O3) films were prepared on Al2O3-TiC substrates by RF diode sputtering. The target sputtering power was varied from 4 to 8 kW. The effects of target sputtering power on the structure and mechanical properties of alumina films were investigated. The results show that the structure of the alumina films deposited at all the target sputtering powers is amorphous. However, … …Physics International, Vol. 4, Issue 1 · 17 Jul 2013 · 6,897 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Optical Properties of ZnO-TeO2 Glass SystemH. A.A. Sidek, S. Rosmawati, Z. A. Talib et al.Problem statement: Systematic series of ZnO-TeO2 glasses with mole fraction of 0.10-0.40 ZnO content with an interval of 0.05 were studied to obtain their physical and optical properties. Approach: All the glass samples were synthesized by rapid melting quenching method under controlled conditions, while their refractive indices (n) were measured by the EL X-02C high precision ellipsometer. The room temperature … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 14,077 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeneral Properties of 3/2ω0 and 2ω0 Harmonics Emission from Laser Driven PlasmasA.S.A. Dib, A.H. BelbachirUsing a simple model based on the conversion of electron plasma waves into electromagnetic waves through a process of parametric interaction of four waves, the general properties of the 3/2ω0 emission and the 2ω0 emission generated by the interaction of a Gaussian laser pulse with homogeneous plasma are studied. Some known characteristics of these emissions are reproduced within this model … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,502 accessesView PDFCite
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 PDFCite
Research ArticleOpen accessAll words, across the recordPhotocurrent and Photoluminescence Investigations of GaInNAs and GaInNAs(Sb) Quantum Wells Grown by Molecular Beam EpitaxyS. Ben Bouzid, F. Bousbih, A Hamdouni et al.We have investigated photocurrent (PC) and photoluminescence (PL) in sequentially grown GaInNAs/GaAs and GaInNAs(Sb)/GaAsSbN quantum wells. Photocurrent transitions are analyzed by theoretical calculations using envelope function formalism taking into account the strain effect and the strong coupling between nitrogen localized state and the GaInAs band gap. The results are consistent with a type I band alignment and a conduction band … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,475 accessesView PDFCite
