The effects of the reactive Ti layer on the resistive switching characteristics of TiN/Ti/TiO 2 /TiN resistive random access memory (ReRAM) are investigated. Nitridation at the top region of Ti during reactive sputtering of the TiN layer and oxygen gettering of Ti from TiO 2 make the TiON/TiO 2- x interface. It result…
We investigated zinc oxide (ZnO) thin films prepared by plasma-assisted atomic layer deposition (PA-ALD), and thin film transistors (TFTs) with the ALD ZnO channel layer for application to next-generation displays. The dependences of the electrical characteristics of the fabricated TFTs on the plasma condition were ev…
NiFe/Cu multilayers were deposited from a single bath in the potentiostatic mode using two different solutions. In solution A , the ionic concentration ratios were Fe 2+ : Ni 2+ : Cu 2+ 9: 60: 10 and in solution B they were 1: 103: 1. To characterize the layers, scanning electron microscopy (SEM), high resolution tran…
The calcium phosphate family of biomaterials includes numerous compounds that might find applicability in orthopedics and dentistry as implant materials. However, only calcium phosphates of higher Ca:P ratio such as hydroxyapatite and tricalcium phosphates have been exposed to extensive investigations. Reports on the…
This paper describes a case study of 3D protein structure prediction of six sequences from protein data bank (PDB) by genetic algorithm and tabu search (GATS), where off-lattice AB model is considered as a simplified model of protein structure. The lowest-energy values required for forming the native conformation of p…
By using electric-field-induced second-harmonic generation (EFISHG) measurement, we probed charging and discharging in an α-NPD/Alq3 organic light-emitting diode [α-NPD, N,N '-di-[(1-naphthyl)-N,N '-diphenyl]-(1,1'-biphenyl)-4,4'-diamine; Alq3, tris(8-hydroxy-quinolinato)aluminum(III)] while electroluminescence respon…
The paper presents the results of experimental research performed at the BN-350 NPP, which have allowed the identification of a local natural circulation phenomenon arising in some sections of the NPP heat removal loops. The nature of this phenomenon and the features of its interaction with a total-circuit natural cir…
Abstract Glycolipids were isolated from extramembraneous light-harvesting complexes, called “chlorosomes,” in a thermophilic green photosynthetic bacterium Chlorobium tepidum. The lipids were first characterized in terms of their precise structures of both hydrophilic (saccharides) and hydrophobic (fatty acids) moieti…
Microstructures of a laser–tungsten inert gas (TIG) hybrid welding joint of dissimilar Mg alloy and steel with and without Ni interlayer are studied comparatively by SEM. The results show that there are a lot of precipitates of Mg17Al12 with mesh structures in the molten pool of Mg to steel dissimilar joints of laser–…
In order to investigate magnetic structure and the mechanism of the Curie temperature (TC) enhancement in TbNi4Co and TbNi4Fe compounds in comparison with TbNi5, electronic structure calculations were performed within the LSDA + U method (local spin density approximation with Hubbard U-correction). Magnetic moments fo…
mechanical, electrical, and thermal performance This unique nano order material can not only be utilized on its own in precision industrial fields but can also provide high performance functionality in conjunction with conventional materials. For this reason, many researchers are investigating the fabrication of CNT r…
The results of comparative studies of wear resistance of ADI versus high manganese Hadfield cast steel are presented. For evaluation of wear resistance three type of ADI were chosen. Two of them were of moderate strength ADI with 800 and 1000MPa tensile strength while the third was 1400MPa tensile strength ADI. The sp…
A new method, by using eigenmodes to reduce the fitting parameters and pre-calculated eddy current based on a lump parameter circuit equation, is applied to reconstruct the vacuum field for EAST plasma startup.
The high voltage power supply for magnetron, used for the microwaves generators in industrial applications is a classical design. This system is composed of a single phase leakage flux transformer supplying a cell composed of a capacitor and a diode, which double the voltage and stabilize the current. An improved π qu…
Aluminium alloys containing 0·3%Fe and 0·05%Si, 0·3%Fe and 0·15%Si, 0·3%Fe and 0·45%Si, and 0·5%Fe and 0·2%Si were solidified with different cooling rates. Shapes of intermetallic particles and their spatial distribution in the alloys were characterised by optical and scanning electron microscopy. X-ray diffraction an…
Charge Injection Error Free (CIEF) Charge-Base Capacitance Measurement (CBCM) technique provides a simple way for accurate measurements of on-chip interconnect parasitic capacitance. We report here for the first time capacitance measurements of on-chip interconnect with resolution values of 1aF or better. We analyze t…
Solid solutions of the CdS-ZnS system deposited as polycrystalline films by aerosol pyrolysis from aqueous solutions of cadmium and zinc thiourea complexes have been studied. The phase composition and solid-phase solubility are dictated by the nature of initial complexes. From solutions of [M(thio)2(CH3COO)2] complexe…
In this paper two-dimensional Photonic Crystal Ring Resonator (2D PCRR) based Add Drop Filter (ADF) is proposed. It's theoretical and numerical analysis is carried out. Using 2D Finite Difference Time Domain (2D FDTD) method, coupling and dropping efficiencies of ADF is investigated. The Photonic Bandgap (PBG) of the…
Both skin effect and proximity effect increase losses in any conductor with time varying current. In order to determine those extra losses in a real case of two three-phase systems, buried together in a ground, the electromagnetic field inside the cables and in vicinity was calculated for four different frequencies. T…
Electron heat transport across the interface between a two-band superconductor with the inter- and intra- band pairing types and a normal metal, and a ferromagnet formed by domains with different magnetization directions is analyzed. The possibility of controlling the heat flow by varying the magnetization direction o…
