X-ray tomography applied to the void/defect measurement of hybrid CFRC/SiC composites
(2019-01-01)
Carbon fiber reinforced carbon composites (CFRC) and carbon fiber reinforced silicon carbide composites (CFRC/SiC) are materials of wide interest in the aerospace industry due mainly to their outstanding thermo-mechanical ...
Gamma-ray and neutrino emission from misaligned microquasars
(EDP Sciences, 2005-12)
Microquasars are accreting X-ray binary systems with non-thermal radio jets. In some of these systems the jet is expected to be strongly misaligned with the perpendicular to the orbital plane. If the donor star is an ...
In situ reactor to image catalysts at work in three-dimensions by Bragg coherent X-ray diffraction
(2019-10-01)
A new reactor dedicated to high temperature Bragg coherent X-ray diffraction imaging (Bragg CDI) of heterogeneous catalysts at atmospheric pressure has been developed. It allows direct visualisation of the shape, surface ...
Syntheses of bismuth titanate templates obtained by the molten salt method
(2013-09-01)
Bismuth titanate templates (Bi4Ti3O12) were synthesized by the molten salt method in Na2SO4 and K2SO4 fluxes, using an amorphous Bi4Ti 3O12 precursor and a mechanically mixed Bi 2O3+TiO2 mixture as the starting materials. ...
