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 ...

The use of magnetic fields in targeted drug delivery, especially for treatment of cancers and tumoral regions, is one of the significant techniques in the field of modern methods of treatment. Considering that many vital biological tissues have been located deep in the body, then for targeted drug delivery and effective treatment in these tissues, it is required to bring therapeutic agent to th...

magnetic field effects on the elastic response of polymeric piezoelectric cylinder reinforced with carbon nanotubes (cnts) is studied. the cylinder is subjected to internal pressure, a constant electric potential difference at the inner and outer surfaces, thermal and magnetic fields. the mori-tanaka model is used for obtaining the equivalent material properties of the cylinder. based on the ch...

ground penetrating radar (gpr) and magnetic methods were used at ghasr-e-shirin town in kermanshah province, southwest of iran for detecting a series of large ancient (ca 1500 years) underground cavities (tagh). the area of study is a historical monument which is named as emarat e khosro. radar and total intensity magnetic field measurements have been done on the eastern part of the complex, wh...

the effect of a transverse magnetic field on the boundary layer flow and heat transfer of anisothermal stretching cylinder is analyzed. the governing partial differential equations for themagnetohydrodynamic, temperature, and concentration boundary layers are transformed into a setof ordinary differential equations using similarity transformations. the obtained ordinarydifferential equations ar...

in the current investigation, fe3o4 water-based nanofluids were synthesized to examine the effect of an alternative 3-d external magnetic field on its thermal behavioral pattern. a solvothermal method was used to prepare the magnetite nanoparticles. to characterize the nanoparticles, the study employed transmission electron microscopy, x-ray diffraction, fourier transform infrared spectroscopy,...
