The dynamic collective properties of the liquid Li0.7-Mg0.3 alloy are studied by molecular-dynamics simulation. The dynamic structure factors and longitudinal current correlations at wave vectors between the hydrodynamic and kinetic regime (0.2,k,4 Å) are analyzed. In order to discuss the influence of the mass difference between particles on the longitudinal modes, the same alloy, except that t...

objective(s):iron oxide nanoparticles have found prevalent applications in various fields including drug delivery, cell separation and as contrast agents. super paramagnetic iron oxide (spio) nanoparticles allow researchers and clinicians to enhance the tissue contrast of an area of interest by increasing the relaxation rate of water. in this study, we evaluate the dependency of hydrodynamic si...
