M. M Tehranchi, S. M Hamidi,

We report an experimental study on optical and magneto-optical properties of Cesubstituted yttrium iron garnet thin films incorporating gold nanoparticles. Au nanoparticles were formed by heating Au thin film on cubic quartz and garnet substrate in vacuum chamber and a Ce:YIG layer was deposited on them by the aid of Pulsed laser deposition method. A large enhancement of the longitudinal Kerr e...

this paper focused on a novel method of electroless plating ruthenium (ru) on solid or porous substrates like porous stainless steel (pss) discs or ceramic tubes. a novel complexing plating bath of ru was developed. it is proven that ru can be deposited directly on these substrates by the bath at a temperature of 328 k and strong alkaline environment. tga, sem, edx and xrd confirmed the success...

The method of using plaster nails for fixing the mansion of Morteza Gholi Khan Egbalosaltaneh, the commander of Maku, in Qajar period was purposed. These paintings are important for art researchers since it is the beginning of a kind of innovation in Iranian art in Gajar period (Fig.1). The western elements have been used in the interior design of the mansion and the execution of interior decor...

In this research, the microstructure of Inconel 625 cladded layer on ASTM A575 steel has been investigated. By examining different parameters, the optimal single-pass sample with the least amount of dilution, porosity and fusion and suitable wetting angle was determined. Then cladding process with the optimal parameter was performed. The microstructure of the cladding layer was evaluated from t...

A four-way power divider/power combiner using substrate integrated waveguide (SIW) and microstrip lines is proposed and investigated. The proposed power divider consists of a double-layer substrate with a bottom layer including an SIW T-junction and a top layer including a microstrip network. This microstrip network consists of a modified Gysel power divider which provides a high isolation betw...
