“…Diluted magnetic semiconductors (DMS) have attracted a lot of attracted in past years because it is a type of semiconductor in which magnetic ions are substituted against the host cations. It shows many applications in producing spintronic devices such as spin-valve transistors [1,2]. ZnO is a compound semiconductor in groups II-IV that has emerged as one of the most promising options for DMS materials [3].…”

The iron and Nickel co-doped in zinc oxide nano-particle, Zn1-x-yFexNiyO {(x=0, y=0), (x=0.05, y=0), (x=0, y=0.05), (x=0.03, y=0.02)} were prepared by Sol-Gel technique. This type of synthesis is used for the manufacture of a Field Effect Transistor (FET) detector which is extremely sensitive, secure, and capable of reproducing. It is also used for the detection of the Piperidine (CH2)5NH (hexahydro pyridone) chemical. The well-closed pack spherical nano-particles of the identified crystalline structure of the usual wurtzite hexagonal phase were achieved by characterization of X-Ray Diffraction (XRD). The blue shift was well observed of Co-doped samples as compared to un-doped or single-doped ZnO nanoparticle samples by UV-visible absorption spectrum. The Fourier Transform Infrared Spectroscopy (FTIR) reveals the existence of chemical bonding and functional groups are established and the occurrence of iron Fe in modes associated with iron Fe in addition to ZnO. The room temperature ferromagnetism was achieved in single or co-doped (Fe-Ni) with ZnO nanoparticles and is confirmed by magnetic characterization (VSM). It was perceived that magnetic saturation was improved in Fe-Ni Co-doped samples relative to pure or single doped. Also, the characterizations of samples show that the exchange interaction of Ni and Fe dominates over Ni-Ni and Fe-Fe interactions.

The present study is focused on the unsteady two-phase flow of blood in a cylindrical region. Blood is taken as a counter-example of Brinkman type fluid containing magnetic (dust) particles. The oscillating pressure gradient has been considered because for blood flow it is necessary to investigate in the form of a diastolic and systolic pressure. The transverse magnetic field has been applied externally to the cylindrical tube to study its impact on both fluids as well as particles. The system of derived governing equations based on Navier Stoke's, Maxwell and heat equations has been generalized using the well-known Caputo-Fabrizio (C-F) fractional derivative. The considered fractional model has been solved analytically using the joint Laplace and Hankel (L&H) transformations. The effect of various physical parameters such as fractional parameter, Gr, M and on blood and magnetic particles has been shown graphically using the Mathcad software. The fluid behaviour is thinner in fractional order as compared to the classical one.

“…According to their work, three mechanisms could play an important role during the drug presence on the target tissue: formation of a droplet of drug, vortex, and creeping flow in entrance regions of the aneurysm vessel. Sharifi et al (2019b) studied blood flow in a channel under the effect of magnetic field of two inclined permanent magnets. Their study was conducted for different inclination angles of magnets and saturated magnetization.…”

Controlling the destructive behavior of the wake region and consequently drag reduction are great challenges in fluid mechanics and ocean engineering. In this paper, the effect of the non-uniform magnetic field on controlling the flow and consequently drag reduction has been studied in laminar flow of magnetic nanofluid around a circular cylinder. The source of the magnetic field is a single current-carrying wire located in the center of the cylinder. The nanofluid consists of Fe3O4 as nanoparticles and water as the base flow. The ranges of Reynolds number (Re), volume fraction (ϕ), and the diameters of nanoparticles are 1.6 < Re < 180, 0 < ϕ < 0.04 and 15 < dp < 25, respectively. The modified Buongiorno model that contains the magnetophoresis term is utilized to perform two-phase modeling of magnetic nanofluid flow. Finite volume method and PISO (Pressure-implicit With Splitting Of Operators) algorithm are utilized for the discretization of the governing unsteady equations including conservation laws of mass, volume fraction transport, and momentum equations by considering the ferrohydrodynamics (FHD) force as the source term. The results showed a significant effect of magnetic field intensity and volume fraction on the flow parameters such as drag coefficient, strouhal number, wake length, etc. In general, increasing the magnetic field in various volume fractions and various nanoparticle diameters reduces the amount of drag coefficient. The effective parameters for flow controlling are ordered as follows regarding their effectiveness: magnetic field intensity, volume fraction and diameter of the nanoparticles, respectively.
