Plants are one of the best sources to obtain a variety natural surfactants in field green synthesizing material. Sambucus ebulus, which has unique properties, been considered promising material traditional Asian medicine. In this context, zinc oxide nanoparticles (ZnO NPs) were prepared using S. ebulus leaf extract, and their physicochemical properties investigated. X-ray diffraction (XRD) results revealed that ZnO NPs highly crystalline, having wurtzite crystal structure. The average...
Abstract In this work, novel two-dimensional BC $$_2$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msub> <mml:mrow/> <mml:mn>2</mml:mn> </mml:msub> </mml:math> X (X = N, P, As) monolayers with atoms out of the B–C plane, are predicted by means density functional theory. The structural, electronic, optical, photocatalytic and thermoelectric properties have been investigated. Stability evaluation single-layers is carried phonon dispersion, ab-initio molecular dynamics (AIMD)...
In the radiation protection application, metal-polymer composites have been developed for their shielding properties. this research, elastomer doped by 10 μm and100nm size of lead, bismuth and tungsten particles as filler with 30 60 wt percentages were prepared. To survey properties polymer using gamma-ray emitted from 152Eu 137Cs sources, gamma flux was measured NaI(Tl) detector, then linear attenuation coefficient calculated. Also, Monte Carlo simulation (MCs) method used. The results...
Abstract Measurement while drilling (MWD) tools include accelerometers, magnetometers and temperature sensors. The accuracy of these sensors are highly important in measuring inclination Azimuth angle parameters a directional well. These factors can increase costs when During the past years, many efforts have been made to tools. Accuracy accelerometer magnetometer influenced by scale, bias non-orthogonal errors. Considering that MWD systems work wide range temperatures (for example 0 °C–150...
By using radio-labeled multifunctional superparamagnetic iron oxide nanoparticles (SPIONs) and an alternating magnetic field (AMF), we carried out targeted hyperthermia, drug delivery, radio-immunotherapy (RIT), controlled chemotherapy of cancer tumors. We synthesized characterized Indium-111-labeled, Trastuzumab Doxorubicin (DOX)-conjugated APTES-PEG-coated SPIONs in our previous work. Then, evaluated their capability SPECT/MRI (single photon emission computed tomography/magnetic resonance...
A Discrete Fourier Transform Method (DFTM) for discrimination between the signal of neutrons and gamma rays in organic scintillation detectors is presented. The method based on transformation signals into frequency domain using sine cosine transforms combination with discrete transform. largely benefited from considerable differences that usually available zero-frequency components norm amplitude DFT gamma-ray signals. Moreover, working naturally results suppression unwanted effects various...
The interaction of laser pulses picosecond duration and terawatt to petawatt power accelerated for the very fast undistorted plasma blocks deuterium DD or tritium ignition is investigated. Based on direct instant conversion energy into mechanical motion by nonlinear (ponderomotive) forces, any thermal pressure generation delayed collision process. Following studying classical frequency, it found that quantum modified at higher energies results in a correction about 15$%$ reduction delay.
