Research ArticleOpen accessIn the abstractEffect of Laser Irradiation on the Structural and Electrical Properties of Co-Zn Ferrite Thin FilmNehad M. TashtoushThin films of irradiated and non-irradiated Co-Zn ferrite was prepared by the thermal evaporation method on a glass substrate. The samples were annealed at 200°C, 400°C and 600°C for 1hr. The XRD analysis of all kinds of films, prepared for this study, shows that the spinel phase is almost completed after annealing. The change of the XRD after annealing is … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,033 accessesView PDF Cite

Research ArticleOpen accessIn the abstractLocalization of Implanted Impurities in SiliconM. Jadan, Jihad S.M. AddasiLocalization of implanted boron impurities at the nodes and interstitial of silicon depending on the implantation current density has been studied by the X-ray diffraction and astrophysical methods. A shares of the impurity at the lattice sites increases with growing current density due to the instantaneous vacancy concentration and suppression of the impurity displacement from the sites by silicon interstitial. …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,712 accessesView PDF Cite

Review ArticleOpen accessIn the abstractBio-Inspired Materials: Exhibited Characteristics and Integration Degree in Bio-Printing OperationsAntreas KantarosIn the last decade, additive manufacturing techniques, commonly known under the term "3d printing" have seen constantly increasing use in various scientific fields. The nature of these fabrication techniques that operate under a layer-by-layer material deposition principle features several de facto advantages, compared to traditional manufacturing techniques. These advantages range from the precise attribution of pre-designed complex shapes to the … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 4 · 29 Nov 2022 · 7,180 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDesign and Optimization of a 1.55 µm Waveguide Based on Silicon Planar Photonic CrystalsR. Bchir, A. Bardaoui, M. Machhout et al.Background: Silicon based Planar Photonic Crystals (PPC) are used for the design of a 1.55 µm waveguide. Line defects are then formed in the PPC structures, by removing rows of holes, to obtain a Planar Photonic Crystal Waveguide (PPCW). Objective: First, we varied the thickness of the Silicon slab and the pore radius in order to obtain optimum design parameters … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,472 accessesView PDF Cite
