Research ArticleOpen accessEvery word in the titleModel of High-Temperature Diffusion of Interstitial Silicon Atoms in SiliconM. Jadan, A. R. Chelyadinskii, V. Yu. YavidProblem statement: Correct description of the anomalous phenomena determined by self-point defects in implanted silicon desires knowledge of their properties. Interstitial Si atoms themselves display anomalies in their behavior and firstly in existence of two very different values of the diffusion coefficient. Approach: We analyzed experimental results and proposed the model of diffusion of interstitial Si atoms in silicon in … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Sep 2009 · 6,862 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAtomic Layer Epitaxial Growth of Gaas on Porous Silicon SubstrateMohamed Lajnef, Afrah Bardaoui, Isabelle Sagne et al.GaAs thin film has been grown on porous silicon by metal organic chemical vapour deposition (MOCVD) for different growth temperatures using atomic layer epitaxy (ALE) technique. The morphology of GaAs layer was investigated by atomic force microscopy (AFM). The effect of growth temperature is studied using photoluminescence measurements (PL).The photoluminescence spectra revealed a dissymmetry form toward high energies attributed to … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 7,027 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA New Efficient-Silicon Area MDAC SynapseZied Gafsi, Nejib Hassen, Mongia Mhiri, Kamel BesbesUsing the binary representation ΣiDi2i in the Multiplier digital to analog converter (MDAC) synapse designs have crucial drawbacks. Silicon area of transistors, constituting the MDAC circuit, increases exponentially according to the number of bits. This latter is generated by geometric progression of common ratio equal to 2. To reduce this exponential increase to a linear growth, a new synapse named … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 7,158 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDisplacement of Boron from the Silicon Crystal Nodes by Interstitial Si Atoms During Implantation and AnnealingM. Jadan, A. R. Chelyadinskii, V. Y. YavidThe process of boron displacement from the nodes into interstitial positions of interstitial Si atoms in silicon (Watkins effect) on the conditions of implantation and annealing has been investigated with the help of X-ray diffraction and electrical methods. It was revealed that the efficiency of the Watkins substitution is determined by the ion current density (level of ionization). With increasing … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,983 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLocalization 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 PDFCite
Research ArticleOpen accessEvery word in the titleStructural and Substrate Interaction Properties of Alkaline Phosphatase from Paenibacillus sp. PSB04: In-Silico AnalysisHerman Umbau Lindang, Cahyo BudimanA Phosphate-Solubilising Bacterium (PSB) of Paenibacillus sp. PSB04 was previously isolated from the Sabah tropical rainforest in Malaysia. Interestingly, the genome sequence of the PSB04 strain harbored an Alkaline Phosphatase (AP) (EC 3.1.3.1) gene and was hypothesized to have unique structural characteristics. Therefore, this study aims to determine the AP three-Dimensional (3D) model and catalytic mechanism from Paenibacillus sp. PSB04 … …OnLine Journal of Biological Sciences, Vol. 22, Issue 3 · 16 Jul 2022 · 5,910 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleMolecular Characterization and in Silico Analysis of Phytochemical Compounds from Plants with Immunomodulatory PotentialHermin Pancasakti Kusumaningrum, Rejeki Siti Ferniah, Siti Nur Jannah et al.The immune system works to protect the body against foreign antigens from microorganisms and abnormal cells. The use of herbal plants as immunomodulators are used to prevent disease attacks. TNFα and interleukin-6 are pro-inflammatory immune systems that cause disease in uncontrolled synthesis. Herbal plants as inhibitors of TNFα and interleukin-6 need to be identified molecularly to reduce the occurrence of … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 27 Nov 2025 · 1,954 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIn silico and in vitro Structural Analysis on the Interaction of Calmodulin and Calmodulin-Binding Motif of FKBP35 from Plasmodium knowlesiSazlinawatie Aladin, Cahyo Budiman et al.FK506-binding protein 35 (FKBP35) is a peptidyl-prolyl cis-trans isomerase found in Plasmodium knowlesi, a zoonotic malaria parasite responsible for concerning cases of malaria infection in East Malaysia. This protein contains a segment known as the calmodulin-binding motif (Pk-CBM), which is predicted to facilitate interaction with calmodulin from P. knowlesi (Pk-CaM). Although this interaction is considered promising for future antimalarial drug … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 10 Mar 2025 · 4,846 accessesView PDFCite
