Studying the effects of adding CeO2 and CuO on electrical properties of lead free (Ba0.85Ca0.15)(Zr0.1Ti0.9)O3 piezoceramics
Lead-free (Ba0.85Ca0.15)[(Zr0.1Ti0.9)]O3 (BCZT) piezoceramics were synthesized using solid-state ceramic processing. In order to improve the electrical properties CeO2 and CuO additives/dopants were used and two methods were employed to introduce theses oxides; one, in which 0.1 mol.% CeO2 was mixed with the raw materials and the composition was balanced for A-site substitution (BCCe0.1ZT) and ...
متن کاملEffect of nano and micron WO3 on microstructure and electrical properties of lead free potassium sodium niobate piezoceramics
Lead free potassium sodium niobate (KNN) piezoceramics were synthesized via conventional solid state sintering route. Nano and micron WO3 were separately added to KNN through ball-milling. Dielectric and piezoelectric properties of samples sintered in the temperature range of 1110°-1145°C were measured by precision LCR-meter and APC d33-meter devices. The results revealed that micron WO3 partic...
متن کاملRequirements for the Transfer of Lead-free Piezoceramics into Application
The recent review for the Restriction of Hazardous Substances Directive (RoHS) by the expert committee, appointed by the European Union, stated that the replacement of PZT “... may be scientifically and technologically practical to a certain degree ...”, although replacement “... is scientifically and technically still impractical in the majority of applications.” Thus, two decades of sustained...
متن کاملthe analysis of the role of the speech acts theory in translating and dubbing hollywood films
از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
