Graphene is a single sheet of sp2 bonded carbon having two-dimensional (2D) layer. It has remarkable electronic, mechanical and thermal properties. In this paper, the graphene oxide (GO) was reduced by reducing chemicals such as ascorbic acid hydrazine then characterized transmission electron microscopy (TEM), Raman spectroscopy Fourier transform infrared spectroscopy. TEM results chemically were showed that structure consists mixture few layers (rGO).
We predict a two-dimensional monolayer polymorph of boron nitride in an orthorhombic structure (o-${\mathrm{B}}_{2}{\mathrm{N}}_{2})$ using first-principles calculations. Structural optimization, phonon dispersion, and molecular dynamics calculations show that o-${\mathrm{B}}_{2}{\mathrm{N}}_{2}$ is thermally dynamically stable. semiconductor with direct band gap 1.70 eV according to based on hybrid functionals. The has high optical absorption the visible range armchair direction while low...
In this study, the hydroxyapatite biomaterials are produced by precipitation method and role of silver doping within different molar ratios 2.0, 5.0, 10.0% investigated with some fundamental analysis, including powder XRD, SEM, EDS, FTIR, Raman, material densities. vitro biocompatibility assessment is conducted cytotoxicity agar diffusion tests. Moreover, genotoxicity tests determine whether cause mutations or not. addition, a hemolytic effect test examines variation behavior compounds....
This work is the continuation of a systematic study on characterization Lu-added Y123 bulk superconducting materials prepared by nitrate compounds and derivatives at 970 °C for 20 h. In this part, effect Lu inclusions physical mechanical properties superconductors examined with aid microhardness measurements performed various applied loads in range 0.245–2.940 N. The measurement results allow us to determine important characteristics such as Vickers microhardness, elastic (Young’s) modulus,...
The magnetic response of Bi-based superconductors nominal composition against low AC field amplitudes is studied in terms fundamental and third harmonic susceptibilities to investigate various physical parameters. Optimum conditions a wet preparation technique have been determined. Both transport inductive critical current densities increased considerably on samples subjected single intermediate grinding. data accompanied by XRD measurements support the theory that minor superconducting...
Abstract The effects of ZnO addition on the microstructure and mechanical properties YBCO have been investigated through XRD, SEM, EDX, ac susceptibility measurements standard Vickers microhardness testing method. We prepared samples by a conventional solid‐state reaction method used an additive for system (0, 0.5 1 wt% ZnO). orthorhombic strain Δ = ( b – )/( + ) increases as Zn content increases, where are relevant lattice parameters samples. superconducting transition temperatures hardness...
