The silk yarn containing Ag nanoparticles was prepared through the chemical reduction under ultrasound irradiation. In this system, ethylene glycol served as a reduction reagent and protecting silver nanoparticles from aggregation. The effect of some parameter, such as power of ultrasound irradiation and temperature in growth of the nanometric Ag were studied. Particle sizes and morphology of n...

AlGaAs/InGaAs/GaAs pHEMT (pseudomorphic high electron mobility transistors) materials and devices have been studied with 20MeV Li ions irradiation at two different fluences. The structural and electrical characteristics have been studied and compared before and after the irradiation. It has been found that with the irradiation FWHM of the material not changes as confirmed with x-ray rocking cur...

In this work, Mg-doped ZnO nanostructures were prepared in water under ultrasonic irradiation for 60 min without using any organic compounds or post preparation treatments. The prepared samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive analysis of X-ray (EDX), diffuse reflectance spectroscopy (DRS...
