Different black pigments of natural origin (mineral or organic) have been examined by means of several analytical methods (colour measurements, elemental analysis and structural analysis). The results, after being compared with each other, then serve

The Book of Hours of Jean II Ie Meingre, Marechal de Boucicaut, is an outstanding example of the advanced state of painting in France at the time of Jean de Berry. It is not surprising that so many art historians held it in such high regard in their

Temperature and species mole fraction profiles have been measured in laminar premixed H-heptane/02/Ar and iso-octane/02/Ar flames. Both flames have been stabilized on a flat-flame burner at low pressure (6.0 kPa), and species identification and conce

The chemical structure of stoichiometric methane–oxygen–argon flames seeded or not with 1% heptafluoropropane (CF3CHFCF3) was measured by the molecular beam-mass spectrometry technique. Both flames were stabilized on a water-cooled flat-flame bur

This study was aimed at comparing the chemical structure of two rich premixed flames Ted respectively with a neat fuel: n-decane and a multi-component fuel, kerosene. Both flames were stabilized on a flat-flame burner at atmospheric pressure. Samples

The objective of this work was to specify the mechanism of flame inhibition by compounds that do not contain bromine. Mole fraction profiles have been measured by molecular beam-mass spectrometer technique in a stoichiometric CH 4 /O 2 /Ar low-pressu

The influence exerted by radiant flux on transient thermal degradation of PMMA and particle board has been investigated. The mass loss rate has been measured continuously during experiments performed on specimens of dimensions equal to 10 x 10 cm in

Thermal degradation of PMMA and particle board subjected to a variable radiant heat flux, under an inert atmosphere has been studied. Two variable rates of the radiant heat flux have been used: 1.66×10 −3 W/cm 2 ·s and 3.33×10 −3 W/cm 2 ·s. S
