Microquasars and Gamma-ray Sources
(Science Press, 2005-12)
Microquasars are X-ray binary systems with non-thermal radio emission originated in jet-like features. They are attractive sites for gamma-ray production, since relativistic particles in the jet should traverse locally ...
Effects of the particle sizes and concentrations on the X-ray absorption by CuO compounds
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
This work presents a study on the effects of the particle size, material concentration and radiation energy on the X-ray absorption. CuO nanoparticles and microparticles were incorporated separately into a polymeric resin ...
Fe K-edge X-ray absorption spectroscopy study of Pb(Fe2/3W 1/3)O3-PbTiO3 multiferroic ceramics
(2013-03-21)
The present paper is a comprehensive study concerning Fe K-edge X-ray absorption spectroscopy (XAS) measurements, which were performed to characterize the local structure of (1 - x)Pb(Fe2/3W1/3)O 3-xPbTiO3 samples as a ...

Reactive sputter magnetron reactor for preparation of thin films and simultaneous in situ structural study by X-ray diffraction
(Amer Inst Physics, 2013-01)
The purpose of the designed reactor is (i) to obtain polycrystalline and/or amorphous thin films by controlled deposition induced by a reactive sputtering magnetron and (ii) to perform a parallel in situ structural study ...
