Descripción
The carbon arc in liquid benzene produces carbon dust in addition to phenylacetyene and a number of other molecular products. The carbon dust was analyzed by Transmission Electron Microscopy (TEM), electron diffraction and Raman spectroscopy, revealing that it consists of a highly structured carbon black with high surface area. The carbon dust from benzene arc was also analyzed with FT-IR spectroscopy suggesting stricking spectral analogy with a mature coal infrared spectrum. During benzene arcing, phenylacetyene undergoes a free radicals induced polymerization to a low molecular weight poly(phenylacetylene).

Nucleosíntesis y procesos moleculares en los últimos estados de la evolución estelar

Las estrellas de masa baja e intermedia (M < 8 masas solares, Ms) representan la mayoría de estrellas en el Cosmos y terminan sus vidas en la Rama Asintótica de las Gigantes (AGB) - justo antes de formar Nebulosas Planetarias (NPs) - cuando experimentan procesos nucleosintéticos y moleculares complejos. Las estrellas AGB son importantes
