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).

Nucleosynthesis and molecular processes in the late stages of Stellar Evolution

Low- to intermediate-mass (M < 8 solar masses, Ms) stars represent the majority of stars in the Cosmos. They finish their lives on the Asymptotic Giant Branch (AGB) - just before they form planetary nebulae (PNe) - where they experience complex nucleosynthetic and molecular processes. AGB stars are important contributors to the enrichment of the
