Size distribution of superparamagnetic particles determined by magnetic sedimentation.
We report on the use of magnetic sedimentation as a means to determine the size distribution of dispersed magnetic particles. The particles investigated here are (i) single anionic and cationic nanoparticles of diameter D approximately 7 nm and (ii) nanoparticle clusters resulting from electrostatic complexation with polyelectrolytes and polyelectrolyte-neutral copolymers. A theoretical express...
متن کاملANALYSIS OF SOME MAGNETIC PROPERTIES OF DILUTED MAGNETIC SEMICONDUCTORS
The susceptibility and specific heat experimental results of the diluted magnetic semiconductors (DMS) are incorporated in a model based on short-range as well as long-range interaction in a random may of magnetic ions. The so-called nearestneighbor pair approximation (NNPA) is applied. It appears that the calculated values of zero field specific heat and Curie-Weiss temperature based on th...
متن کاملSize Distribution Characterization Of Outdoor Aerosol Particles
Mass size distributions of atmospheric aerosol particles were measured at four different regions in outdoor of El-Minia governorate (Upper Egypt). The study was conducted during March 2012 to March 2013. Measurements were performed using low pressure Berner cascade Impactor as an aerosol sampler. The Impactor operates at 1.7 m3/h flow rate with aerodynamic "cut-off" size range from 0.06 up to 1...
