Study of the effect of shape on acoustic performance of micro perforated absorbent at low frequencies

Introduction: Micro-perforated absorbents are one of the structures that are widely used nowadays. The sound absorption mechanism is performed by viscous energy losses in the cavities on the plate. In this study, the acoustic properties of non-flat perforated panels in oblique angle was investigated in numerical method. Material and Methods: This paper examined the effect of the surface shape ...

Study of the effect of particle size on the specific absorption rate of cobalt ferrite nanoparticles in a radio frequency magnetic field

Studies show that the size of magnetic nanoparticles has an important impact on their properties. So, the possibility of an optimal size for their use in medical applications has been reported. Therefore, in this study, cobalt ferrite nanoparticles were prepared using co-precipitation method  at 80°C; then the powder was annealed  in a furnace at 150, 200, 300, 400, 500 and 600°C to obtain nano...
