In this paper, we present a new structure of applying two electrical power supplies to generate ionic wind. In this configuration, two power supplies were applied simultaneously with a modulated voltage to an electrohydrodynamic (EHD) system then corona discharge parameters and EHD thrust characterization was investigated by a corona dryer mechanism. The EHD thrust experiments […]
Nanocrystalline boron doped tin oxide and boron and silver co-doped SnO2 was successfully prepared by using simple sol-gel method. The structural property of as-prepared nanocrystalline materials was investigated by using X-ray powder diffraction, Raman spectroscopy, Fourier transform infrared spectroscopy and scanning electron microscopy. The infrared spectra of the prepared samples showed an incorporation of B […]
The study deals with amplification of a propagating slow wave interacting with an annular hollow electron beam in a helix slow wave structure (SWS). The role of thermal plasma density in a ratio of the axial pointing flux in the plasma region is also investigated. This ratio is small for lower plasma densities. The effects […]
Based on the Density Functional Theory (DFT) and Generalized Gradient Approximation (GGA), the structural, electronic, and band alignment properties of the interface of FeCrP film with graphene-like BN (g-BN) were studied. These properties have been investigated at three different distances between FeCrP film and g-BN. In all three mentioned distances, the ground state point and […]
The interaction of cold plasma with heterogeneous catalysts has led to some peculiar behavior, especially with silica (SiO2) seeding in presence of 2% alumina (Al2O3). In this paper, we have measured plasma parameters in low temperature arc plasma. I – V characteristics of Langmuir probes are plotted using the data obtained from the experimental set […]
Since the discovery of the Dirac equation, much research has been done on the construction of various sets consisting of Dirac matrices that all of which follow the Cliford Algebra. But there is never notice to the relationship between the internal elements of these matrices. In this work, the general form of 2×2 Dirac matrices […]
In this paper, considering the importance of ion acoustic waves in nonlinear phenomena of plasma, the combined effects of nonextensivity and nonthermality parameters on the ion acoustic cnoidal nonlinear waves studied. In this regard, the hybrid Cairns-Tsallis distribution function used to describe the electrons and positrons. Conditions of formation of nonlinear ion acoustic waves and […]
In this paper, the design, performance and characterization of a low temperature argon plasma jet with a Surface Dielectric Barrier Discharge (SDBD)-like structure are presented. Based on this structure, the argon plasma jet is generated in a SDBD-like structure with a mixed electric field. SDBD-like structure, refers to the plasma jet generated by the surface […]
Skyrme Forces (SF) Based Mean Field Model (MFM) or related density function is widely used to describe nuclear states, collective vibrational excitation, and heavy-ion collisions. To investigate 100Sn+16O and 100Sn+48Ca collisions on a 3-dimensional(3D) mesh with Skyrme SV-bas forces in Ecm=100, 150, and 200 MeV, Time-Dependent Hartree-Fock Skyrme(TDHFS) computations were done. The effective interaction in the computation […]
In the present paper, the micron-size silver and titanium powder with desired weight ratios is used to produce the silver-titanium nanocomposite using the self-developed thermal plasma equipment. The mixture is fed into the plasma torch flame by the powder feed system and argon carrier gas. After evaporation, the particles are cooled inside the cooling chamber […]
