Comparing the electromechanical properties of CaTiO3- and BaZrO3-modified Bi0.5Na0.5TiO3–SrTiO3 ceramics

Nanoscale electromechanical properties of CaCu3Ti4O12 ceramics

investigation of the electronic properties of carbon and iii-v nanotubes

boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...

LOW-TEMPERATURE SINTERING AND MICROWAVE DIELECTRIC PROPERTIES OF (Zn0.65Mg0.35)TiO3-CaTiO3 CERAMICS WITH H3BO3 ADDITION

Low-melting H3BO3, acting as sintering aid, was used to reduce the sintering temperature of 5 wt.% CaTiO3-doped (Zn0.65Mg0.35)TiO3 ceramics. The sintering behaviors, microstructures and microwave dielectric properties with different amounts of H3BO3 addition were investigated. The results showed that H3BO3 additive was very effective for lowering the sintering temperature and improving the bulk...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
