core-shell nanostructures are emerging as more important materials than alloy nanostructures and have much more interesting potential applications in various fields. in this work, we demonstrated the fast and facile synthesis of core-shell nanoparticles consisting of pt thin layer as the shell and ni nanoparticles as the cores. the described method herein is suitable for large-scale and low-cos...

Buckling of imperfect thin shell tank which is subjected to uniform axial compression is analyzed. The effect of internal pressure on the stability of a shell tank filled with a homogeneous-heterogeneous liquid was considered. Investigation of the liquid nature effect on reduction of the shell buckling load is performed by using the finite elements method. Calculating results in terms of analyt...

This paper presents the results of an investigation on the effect of a thin low-dielectric material (phantom shell) on measuring the Specific Absorption Rate (SAR) in the frequency range of 3 to 6 GHz. The International Electrotechnical Commission (IEC) has started to develop a SAR measurement procedure in order to cover such frequencies. In the procedure, the SAR is measured in a liquid phanto...
