A sol-gel technique under ultrasonic irradiation was applied to synthesize ZrO2/TiO2/ZnOnanocomposites. X-ray diffraction analysis confirmed the successful synthesis of nanocomposites. The strain and crystalline size values of ZrO2/TiO2/ZnO nanocomposites are estimated to be 9.98×10-4 and 17.66 nm, respectively. The linear absorption coefficient of ZrO2/TiO2/ZnO nanocomposites was measure...
In this paper, the resonance optical absorption method, is used to measure the Cu atoms number density in different power levels of power supply. Atoms are sputtered from a Cu target during plasma magnetron sputtering deposition. For the light source, a commercial Cu hollow cathode lamp is used. For measurement of gas temperature, a small percentage of N2 is added to the gas mixture and the gas...
august wilson is undoubtedly one of the rare black playwrights whose works have attracted streams of attention and worldwide audience. the present study aims at analyzing fences and piano lesson which are two of the most successful plays in his pittsburgh cycle from the perspective of michel foucault’s theories and ideas. studying these two plays from foucault’s perspective opens new windows in...
in this paper a comprehensive approach is presented to improve power swings damping based on direct lyapunov method. the approach combines superconducting magnetic energy storage (smes) system with static synchronous compensator (statcom). considering the energy absorption/injection ability of smes, in transient states the combination exchanges both active and reactive powers with power system....
the main object of this study was to compare the natural and synthetic( naa and nam) zeolites as absorbents in removing emulsified and dissolved traces of organic compounds, which appear in the wastewater of power plants, refinery and petrochemical complexes. the specific objectives of the work was: a) to select the best species that have the highest amount of absorption; b) to measure the ra...
The average power of solid-state and fiber lasers has considerably increased during the last ten years. The 10 kW power is not record-breaking any longer, and a topical problem nowadays is to create lasers with a power of 100 kW. Therefore, the study of thermal effects caused by absorption of laser radiation in the bulk of optical elements becomes ever more important. The Faraday isolator (FI) ...
We have successfully demonstrated all-optical wavelength conversion of a 640-Gbit/s line-rate return-to-zero differential phase-shift keying (RZ-DPSK) signal based on low-power four wave mixing (FWM) in a silicon photonic chip with a switching energy of only ~110 fJ/bit. The waveguide dispersion of the silicon nanowire is nano-engineered to optimize phase matching for FWM and the switching powe...
