In this study, effects of numerous physical quantities like dissipation, thermal radiation, and induced magnetic field on magnetohydrodynamic Casson fluid flow through a vertical plate is addressed. The non-dimensional multivariable governing equations are solved numerically by by means of Runge-Kutta method along with shooting technique. The behavior of velocity, temperature and induced magnet...

in this paper we studied the thermal negativity in a two-qubit xx spin ½ chain model and xxx spin1/2 chain model(isotropic heisenberg model)spin-1/2 chain subjected to an external magnetic field inz direction. we calculate analytical relation for the thermal negativity for two qubit xx and xxx spinchain models in the external magnetic field. effects of the magnetic field and temperature on then...

Cobalt ferrite nanoparticles (CoFe2O4) are well known for some distinctive characteristics such as high magnetic permeability and coercive force, good saturation magnetization, excellent physical, and chemical stability, which make them so attractive for magnetic storage, magnetic resonance imaging (MRI), drug delivery, optical-magnetic equipment, radar absorbing materials...

in this work we report synthesis and magnetic characterization of cobalt doped zno nanoparticles (with different percent of doped cobalt oxide). synthesis of the materials was carried out at room temperature by polyacrylamide-gel method, using zink sulfate and cobalt nitrate as source materials, acrylamide as monomer and n,n-methylene bisacrylamide as a lattice reagent. characterization of the ...

magnetic cufe2o4 nanoparticles were synthesized by a facile microwave-assisted reaction between cu(no3)2 and fe(no3)3. the magnetic nanoparticles were added to starch to make magnetic polymeric nanocomposite. the nanoparticles and nanocomposites were characterized using x-ray diffraction and scanning electron microscopy. the magnetic properties of the samples were investigated using an alternat...

in this paper we report synthesis of fe2tio5-5a zeolite (z5a) nanocomposites with 5%, 10% and 20% weight percent of fe2tio5 in 5a zeolite in stearic acid media after calcination of the gel samples obtained at 600-900°c for 2 hrs. the powder x-ray diffraction (xrd) patterns have been used for characterization of the prepared samples. the scanning electron microscopy (sem) images and x-ray energy...
