چکیده
The piezoelectric phenomena uses in various helpful applications, such as printing of inkjet, the detection sound and production high voltage electricity different electronic devices. In present research, polyethylene oxide (PEO), poly(methyl methacrylate) (PMMA) poly(N-vinyl pyrrolidone) (PVP) were separately dissolved deionized water. These polymers mixed with ratio 0.6:0.2:0.2 wt%, respectively before loaded 0.0, 0.02, 0.04 0.06 wt% zirconium dioxide nanoparticles (ZrO2NPs) via casting method to prepare nanocomposite (NCs) films. optical microscope (OM) showed good diffused NPs into matrix homogenous distribution. functional groups k1 specimen diagnosed Fourier transformation infrared (FTIR). ultrasonic wave (USW) properties studied for frequencies (25, 30, 35, 40 45) kHz. USW coefficients clearly affected by frequency varied. decreased increasing except compressibility. dielectric constant sample was notable improved up 85% applied load. succeeded be used sensor. New NCs film presented promising material wide electrical mechanical applications.

Solid electrolytes based on doped cerium oxide, Ce(M)O2-δ (M = rare-earth cations), are of considerable interest for potential use in low temperature solid oxide fuel cells (LTSOFCs) due to its higher ionic conductivity than YSZ based solid electrolyte. In this research work, crystalline, pure Ce1-xMxO2-δ (where M = Gd or Sm, x = 0.10 or 0.20) based nanoparticles were prepared by chemical prec...
متن کاملPreparation and Characterization of Cerium Doped Titanium Dioxide Nanoparticles by the Electrical Discharge Method
Titanium dioxide nanoparticles (TiO2) are known as a widely used photocatalyst. In order to improve the performance of these nanoparticles, the recombination of the electron-cavity pair must be reduced and the absorption rate of the visible region should be expanded. One way to increase the performance of these nanoparticles is using cerium doped TiO2. In the present study, pure and doped titan...

An Nd doped ZnO (1-5%) photocatalyst was successfully synthesized via chemical co-precipitation method. The optical property, nature, and morphology of the synthesized nanoparticles were analyzed by UV-Visible, XRD, and FESEM respectively. XRD study reveals that Nd has been effectively incorporated in the ZnO lattice in the lower level dosage; however, the crystalline nature has been distor...
