in this thesis,spin dependend transport and electron transport through of ng/sg(graphene/ superconductor graphen) are studied in the junction of ng/fgt/sg. due to andreev reflection conductance increases in the presence of superconductor graphene.also, by applying a voltage gate on a superconductor, fermi level shifts and the conductance is independent of ferromagnatic substrate. also, the cond...
in this study, the morphological and chemical properties of carob pods and carob beans as well as the effect of different extraction, and purification methods on the physical and chemical properties of the purified gums have been investigated. in order to dehusk carob beans, boiling water as well as acidic methods were used. the endosperm powder was prepared and the effect of endosperm powder c...
natural rubber/fiber composites were prepared in a laboratory mixer using new and waste short nylon fiber by a one-step mixing process. fiber loading and bonding agent effects on the microstructure and mechanical properties of the composites were studied. the cure characteristics of composites were investigated by using rheometer. cure and scorching times of the composites decreased while maxim...

bonding to dentin is a promising property, which can prevent leakage and improve the sealing ability of endodontic filling materials. resilon was developed and recommended initially because the existing root canal filling materials did not bond to root canal dentin. since its introduction in 2004, numerous reports have been published regarding various aspects of this material. this article aime...
