Effect of the morphology of thermally reduced graphite oxide on the mechanical and electrical properties of natural rubber nanocomposites
(Elsevier, 2016)
Graphene materials often are obtained through thermal reduction of graphite oxide. This is due to the fact that other synthesis methods are more difficult and generally render lower yield. The structure and morphology of ...
Influence of temperature on the microstructure and electrical properties of BBT thin films
(Taylor & Francis Ltd, 2003-01-01)
The BBT films were prepared by a spin-coating process from the polymeric precursor method (Pechini process). In order to study the influence of the temperature on the BBT microstructure and electrical properties, the films ...
A novel single-phase ZCS-PWM high power factor boost rectifier
(Institute of Electrical and Electronics Engineers (IEEE), 1997-01-01)
This paper presents a novel single-phase high power factor PWM boost rectifier, featuring soft commutation of the active switches at zero-current (ZCS). It incorporates the most desirable properties of the conventional PWM ...
Effect of structural anisotropy on electrical and magnetic properties of polyaniline conducting films
(2013-03-12)
It is shown that highly conducting films of polyaniline protonated with di-esters of sulfosuccinic and sulfophthalic acids which contain alkyl- or alkoxy-type substituents exhibit highly anisotropic structural, electrical ...

Asymmetrical magnetization in three-phase core type transformers
(1995-12-01)
The performance of the three-phase core type transformers, under AC/DC double excitation is discussed in this work. It is presented a mathematical model that considers the mutual coupling between phases and the magnetic ...
