New materials for the electromechanical and acoustoelectric transducers

The technology for creation of the polymer-microsized piezoelectriccomposite substrate is developed by employing the electric gas dis-charge plasma method. It is determined experimentally that as aresult of the nano-structurization of the volume of the polymer-pie-zoceramic composite close to the surface it is Young and piezo-modulus as well as the mechanical quality and electromechanicalcoupling coefficients and the dielectric constant has been increased,whereas, tangent losses are decreased depending on the type of thenanoparticle and its volume rate

Thermo Luminescence Dating of Pottery Sample from Chukhur Gabala Archaeological Site in Gabala District of Azerbaijan

The age of fragments of the ancient pottery sample from Chukhur Gabala archeological site in Gabala district of Azerbaijan has been estimated by employing Thermoluminescence dating (TL) method. The annual dose rate was obtained using γ-spectrometer with a hyper-pure germanium detector and it was 2.741±0.121 mGy/year. The age of the sample was calculated by an additive dose method as 2230±510 years which are in line with the stratigraphically estimated age of this area
