Effect of different sizes of balls on crystalline size, strain, and atomic diffusion on Cu-Fe nanocrystals produced by mechanical alloying
Journal of Theoretical and Applied Physics - Tập 6 - Trang 1-7 - 2012
Mohammad Reza Vaezi, Seyed Hesam Mir Shah Ghassemi, Ali Shokuhfar
Effects of ball diameter on the crystalline size, induced strain, and atomic diffusion in Cu-50%Fe immiscible alloy system have been investigated. Milling parameters affect atomic diffusion in binary or ternary systems separately. The aim of this research work is to prove the fact that ball diameter is an important parameter. It is shown that different diameters can change milling power, and conse...... hiện toàn bộ
Investigation of carbon monoxide gas adsorption on the Al2O3/Pd(NO3)2/zeolite composite film
Journal of Theoretical and Applied Physics - - 2020
Nastaran Mozaffari, Alireza Haji Seyed Mirzahosseini, A. H. Sari, Leila Fekri Aval
AbstractIn this study, Al2O3/Pd(NO3)2/zeolite composite films have been fabricated by roll coating method and characterized by X-ray diffraction, energy-dispersive X-ray spectroscopy and field emission scanning electron microscopy. The gas adsorption was tested in an experimental se...... hiện toàn bộ
Effect of substrate temperature on ZnS films prepared by thermal evaporation technique
Journal of Theoretical and Applied Physics - Tập 9 - Trang 185-192 - 2015
Rahul Vishwakarma
The nanocrystalline ZnS semiconducting thin films of 500 nm thickness have been deposited on glass substrate at different substrate temperatures (T s) by thermal evaporation technique. The structural property of deposited thin films has been measured by X-ray diffraction, scanning electron microscopy, and Energy dispersive analysis of X-ray. The electrical and optical prope...... hiện toàn bộ
Unsteady isothermal flow behind a magnetogasdynamic shock wave in a self-gravitating gas with exponentially varying density
Journal of Theoretical and Applied Physics - Tập 8 - Trang 1-8 - 2014
G. Nath
The propagation of spherical (or cylindrical) shock wave in an ideal gas with or without gravitational effects in the presence of a constant azimuthal magnetic field is investigated. Non-similarity solutions are obtained for isothermal flow between the shock and the piston. The numerical solutions are obtained using the Runge–Kutta method of the fourth order. The density of the gas is assumed to b...... hiện toàn bộ
Effect of indium substitution on the electrical and magnetic properties of Ni–Zn ferrite
Journal of Theoretical and Applied Physics - Tập 9 - Trang 267-272 - 2015
B. B. V. S. Vara Prasad
Indium-substituted polycrystalline nickel zinc ferrites of different compositions Ni0.65Zn0.35Fe2−x In x O4 (x = 0.00, 0.04, 0.08, 0.12, 0.16, 0.2) have been prepared by solid-state reaction route. Calcination and sintering of all samples were done in air atmosphere at 950 °C and 1250 °C, respectively, followed by natural cooling to room te...... hiện toàn bộ
Transcriptional responses following seed priming with cold plasma and electromagnetic field in Salvia nemorosa L.
Journal of Theoretical and Applied Physics - Tập 14 - Trang 323-328 - 2020
Maryam Ghaemi, Ahmad Majd, Alireza Iranbakhsh
This study was conducted to monitor the plant responses to seed priming with electromagnetic fields (0, 4, or 6 mT) or cold plasma (0, 80, or 100 s) in Salvia nemorosa. The cold plasma or electromagnetic field treatments significantly increased shoot fresh weight (49%), root fresh weight (41%), and root length (56%). The results highlighted that seed priming with cold plasma or the electromagnetic...... hiện toàn bộ
Evolution of solitons and their reflection and transmission in a plasma having negatively charged dust grains
Journal of Theoretical and Applied Physics - - 2014
Renu Tomar, Anjali Bhatnagar, Hitendra K. Malik, Raj P. Dahiya
Theoretical calculations are carried out for studying soliton’s reflection and transmission in an inhomogeneous plasma comprising ions, two temperature electrons and negatively charged dust grains. Using reductive perturbation technique, relevant modified KdV equations are derived for the incident, reflected and transmitted solitons. Then a coupled equation is obtained based on these mKdV equation...... hiện toàn bộ

Investigation of the optimal material type and dimension for spallation targets using simulation methods
Journal of Theoretical and Applied Physics - Tập 8 - Trang 1-11 - 2014
S. A. H. Feghhi, Z. Gholamzadeh, C. Tenreiro
Accelerator-driven systems are extensively developed to generate neutron sources for research, industrial and medical plans. Different heavy elements are utilized as spallation targets to produce spallation neutrons. Computational methods are efficiently utilized to simulate neutronic behavior of a spallation target. MCNPX 2.6.0 is used as a powerful code based on Monte Carlo stochastic techniques...... hiện toàn bộ
