Effects of variations in magnetic Reynolds number on magnetic field distribution in electrically conducting fluid under magnetohydrodynamic natural convection
In this study the effect of magnetic Reynolds number variation on magnetic distribution of natural convection heat transfer in an enclosure is numerically investigated. The geometry is a two dimensional enclosure which the left wall is hot, the right wall is cold and the top and bottom walls are adiabatic. Fluid is molten sodium with Pr=0.01 and natural convection heat transfer for Rayleigh num...
متن کاملPalladium Loaded on Magnetic Nanoparticles as Efficient and Recyclable Catalyst for the Suzuki- Miyaura Reaction
Palladium is the best metal catalyst for Suzuki cross coupling reaction for synthesize of unsymmetrical biaryl compounds. But its high cost limits its application in wide scale. Using of nanoscale particles as active catalytic cites is a good approach for reducing needed noble metal. By loading precious nanoparticles on magnetic nanocores as a support, recycling and reusing of catalyst will be ...
متن کاملPalladium nanoparticles immobilized on multifunctional hyperbranched polyglycerol-grafted magnetic nanoparticles as a sustainable and efficient catalyst for C-C coupling reactions
This study offers an exclusive class of magnetic nanoparticles supported hyperbranched polyglycerol (MNP/HPG) that was functionalized with citric acid (MNP/HPG-CA) as a host immobilization of palladium nanoparticles. The MNP/HPG-CA/Pd catalyst was fully characterized using some different techniques such as thermogravimetric analysis (TGA), x-ray diffraction (XRD), transmission electron microsco...
متن کاملMagnetic memory in discrete media observed by coherent soft x-ray resonant scattering
Using soft x-ray resonant magnetic scattering with a coherent beam, we find evidence for memory effects in the magnetic configuration of a periodic array of submicron ferromagnetic lines under external magnetic field. The memory effect is explained by the dipolar coupling between the lines which is lost when the sample is saturated by the external magnetic field. 9 Author to whom any correspond...
متن کاملScattering mechanism of nonmagnetic phase on nano diluted magnetic semiconductors (DMS)
This paper shows the scattering mechanism at diluted magneticsemiconductors. The doped magnetic atom produces a scattering potential due to becoupled of itinerant carrier spin of host material with magnetic momentum of the dopedmagnetic atom. Formulas of scattering event were rewritten by the plane waveexpansion and then the electron mobility of DMS was calculated. Calculations showKondo effect...
