In this work we studied the radiation shielding features of Li2O-Sb2O3-PbO-GeO2-Cr2O3 glass systems at different energies ranging from 0.284 to 1.33 MeV. The maximum linear attenuation coefficient (LAC) for the germinate glasses is in the order of 0.680-0.707 cm-1 and this is reported at 0.284 MeV, whereas the minimum LAC is observed at 1.33 MeV and varied […]
This study investigates the effects of incorporating gold nanoparticles (Au NPs) into a MEH-PPV polymer on its fluorescent properties. Analysis of the fluorescence spectrum of the polymer reveals a significant increase in fluorescence intensity upon the addition of Au NPs. Further investigation using Laser Induced Fluorescence (LIF) spectra demonstrates that the purified polymer emits light […]
In addition to the fact that waves have been proven in different plasma environments, they have also been investigated under different physical regimes. In this research, the propagation of electromagnetic waves in quantum semiconductor plasma in the presence of a uniform external magnetic field was investigated using the quantum hydro magnetism model. The researches that […]
The present report describes the deposition of SiC-NiCr films on Zr substrates under an H2 gas environment by plasma focusing (PF). Using the spark plasma sintering (SPS) method, the anode for the plasma focus device was made from SiC, Ni, and Chromium powders. X-ray diffraction (XRD) of SiC-NiCr samples shows a change in the position and […]
The present experimental study aims to synthesize and evaluate the magneto-plasmonic properties of metallic nanoparticles to introduce a hybrid of core-shell nanoparticle that can be used in biomedical and optical applications. For these core-shell nanoparticles, gold (Au) was used as the plasmonic material and iron (Fe) as the partner in the magnetic parts. The core-shell […]
In this paper, we study obliquely propagating of small amplitude ion acoustic waves (IAWs) in non-relativistic cold plasma in which the ions are viscous fluid, electrons distribution is Maxwellian and external magnetic field varies in space. Using the reductive perturbation method, a nonlinear equation which complies with Korteweg–de Vries–Burgers (KdVB) equation is derived for this […]
An atmospheric pressure plasma microjet device with a tapered ground electrode and dielectric barrier is developed. The effects of the powered electrode geometry and input power on the specifications of the launched RF plasma jets are investigated. Needle-powered electrodes with different types, shapes, lengths, and diameters, such as perforated and un-perforated hollow cylindrical tubes with […]
The use of clay-based nanocomposites as bioadsorbents was considered in this research due to their high mechanical and chemical stable properties, cheapness, compatibility, and abundance in nature. Thermal solution method was used to produce montmorilonite-alginate-zein (MMTALgZ) nanocomposites to remove tartazine dye. Zein and alginate polymers were used to modify the surface of clay. The samples […]
In this research, we investigate the bending of photon light and/or time-like geodesics within the context of four-dimensional space-time geometry, specifically in the presence of topological defects. These topological defects manifest as cosmic string space-time configurations, encompassing screw dislocation, spiral dislocation, and spacelike dislocation. Our primary objective is to determine the extent of deflection experienced […]
The resonance effect happens in very number of natural oscillators and very important in a lot of phenomena. In the surface of a hydride metal, the resonance effect causes the kinetic energy of electrons is increased until they can cooperate inverse-β interaction. This reaction can be done in the electrolysis of palladium and platinum in […]
