Investigation of the mechanic, electromagnetic characteristics and shielding effectiveness of concrete with boron ores and boron containing wastes
(Elsevier, 2020)
In this study, mechanical properties electromagnetic (EM), and shielding effectiveness of concrete samples containing boron product and wastes was investigated in details. In order to increase shielding effectiveness of ...
Properties and High-Temperature Wear Behavior of Remelted NiCrBSi Coatings
(Springer, 2020)
Remelted NiCrBSi coatings were examined using optical microscopy, scanning electron microscopy, energy dispersive spectroscopy, x-ray diffraction analysis, microhardness and wear testing. After wear tests, the surfaces of ...
Effect of Cr/Sb doping and annealing on nonlinear absorption coefficients of SnO2 /PMMA nanocomposite films
(Elsevier, 2020)
Cr and Sb doped SnO2 nanoparticles were synthesized by hydrothermal method. The structural measurements of as-grown nanoparticles exhibited that the incorporation of the 3% wt. Cr and Sb dopant into the SnO2 crystal structure ...
Mutual Coupling Reduction of Cross-Dipole Antenna for Base Stations by Using a Neural Network Approach
(Mdpi, 2020)
In this manuscript, a resonator layer is presented for the purpose of reducing the mutual coupling effect between each antenna element of a cross dipole antenna. In design processes, an artificial neural network approach ...
Electromagnetic Scattering Properties of MWCNTs/Graphene Doped Epoxy Layered with PVC Nanofiber/E-Glass Composites
(Springer, 2020)
In this study, composites composed of glass fiber reinforced-epoxy laminates interleaved with electrospun polyvinylchloride (PVC) nano-fibres were designed for radar absorption investigations. The laminated composites which ...
Electromagnetic simulations of polarization-insensitive and wide-angle multiband metamaterial absorber by incorporating double asterisk resonator
(Indian Acad Sciences, 2020)
A novel multiband metamaterial absorber (MTMA) is proposed which is capable of well presenting a polarization-insensitive and wide incident angle stability in the microwave frequency range. The proposed MTMA comprising two ...
Design of a Broadband Coplanar Waveguide-Fed Antenna Incorporating Organic Solar Cells with 100% Insolation for Ku Band Satellite Communication
(Mdpi, 2020)
A broadband coplanar waveguide (CPW)-fed monopole antenna based on conventional CPW-fed integration with an organic solar cell (OSC) of 100% insolation is suggested for Ku band satellite communication. The proposed ...
Iron oxide-Si nanoparticle magnetic core-shell induced by the interaction of d-orbitals of Fe2+ with reconstructed Si dimer-like defects
(American Institute of Physics Inc., 2020)
Redox-type charge exchange between Si nanoparticles and aqueous metal ions m(x+) was recently used to synthesize core-shell nanocomposites in which their functionalities have been integrated. The process requires the ...
Production of new electromagnetic wave shielder mortar using waste mill scales
(Elsevier, 2020)
Electromagnetic (EM) wave shielder mortar can be produced by mixing cement, natural limestone, tap water with mill scale (mill scale-I and mill scale-II) which is one of the biggest disposal area problems of the iron-steel ...
The effects of interface and matrix reinforcements on fracture toughness of E-Glass/epoxy laminate
(Institute of Physics Publishing, 2020)
In this study, the effects of low amount (0.1 wt%) multi-walled carbon nanotube (MWCNTs) distributed homogenously in epoxy via cationic surfactant (cetyl pyridiniumchloride-CPC), polyacrylonitrile nanofiber (in the range ...
