Sentence examples for formation of char from inspiring English sources
The application of irradiation dosage up to 250 kGy has rapidly improved the thermal stability of blends by delaying decomposition temperature and also promoting formation of char.
The sol gel treatments have proved to play a protective role on the degradation of the cotton fibres, hindering the formation of volatile species that fuel the further degradation and favouring the formation of char.
The residue after burning was analyzed by scanning electron microscopy, infrared spectroscopy and X-ray photoelectron spectroscopy and their results suggest that the coating performs perfect flame retardant effect on cotton owing to the synergistic effect of PHMGP with APP by facilitating the formation of char.
Degradation products continually collect on the GO, which serves as a template for the formation of char.
In addition, the formation of char is reduced through Guebert reaction and esterification reactions, as it can be observed in scheme.
This is because GO exhibits a barrier effect, while TNTs can catalyze the formation of char and exhibits adsorption effect and radical adsorption effect.
