  author={Luann Becker and Theodore E. Bunch and L. J. Allamandola},
Fullerenes (C60and C70) were discovered during investigations of the mechanism by which carbon molecules form in interstellar and circumstellar shells. Unlike diamond and graphite, the other pure forms of carbon, fullerenes are extractable in an organic solvent such as toluene, which led to the detection of the higher fullerenes (C100to C250) in carbon-arc-evaporated soot material. We have applied a similar solvent extraction procedure to an acid residue of the carbonaceous chondrite from the… Expand

It is determined that both the Allende and Murchison fullerene cage structure and the KTB fullerenes contain trapped noble gases with ratios that can only be described as extraterrestrial in origin. Expand
Fullerenes in Meteorites and the Nature of Planetary Atmospheres
We address the hypothesis that fullerenes are an important carrier phase for noble gases in carbonaceous chondrite meteorites. Unlike other proposed carbon carriers, nanodiamond, SiC, graphite andExpand
Fullerene-like carbon nanostructures in the Allende meteorite
Abstract Transmission electron microscopy has been used to examine carbon isolated from the Allende meteorite. The structure of the carbon is rather disordered, consisting of curved and facetedExpand
Terrestrial and Extraterrestrial Fullerenes
Abstract This paper reviews reports of occurrences of fullerenes in circumstellar media, interstellar media, meteorites, interplanetary dust particles (IDPs), lunar rocks, hard terrestrial rocks fromExpand
Fullerenes and Buckyonions in the Interstellar Medium
We show that photoabsorption by fullerenes and buckyonions (multishell fullerenes) explain the shape, width, and peak energy of the most prominent feature of interstellar absorption, the UV bump atExpand
Fullerenes in asphaltenes and other carbonaceous materials: natural constituents or laser artifacts.
The formation of fullerene artifacts seems particularly common for LDI-MS analysis of asphaltenes and other carbonaceous samples with considerably high levels of PAH and varies according to the type of laser used, and the intensity of the laser beam. Expand
Adsorption of Organic Molecules on Onion-Like-Carbons: Insights on the Formation of Interstellar Hydrocarbons
Using atomistic simulations, we characterize the adsorption process of organic molecules on carbon nanoparticles, both of which have been reported to be abundant in the interstellar medium (ISM). ItExpand
Extraterrestrial Organic Compounds in Meteorites
Many organic compounds or their precursorsfound in meteorites originated in the interstellar or circumstellarmedium and were later incorporated intoplanetesimals during the formation of thesolarExpand
Natural C 60 and Large Fullerenes: A Matter of Detection and Astrophysical Implications
Fullerene was theoretically predicted and experimentally discovered, but its detection in laboratory studies is still underrepresented with respect to its theoretical abundance. Recent HighExpand
Multiwall and bamboo-like carbon nanotubes from the Allende chondrite: A probable source of asymmetry
This study presents multiwall and bamboo-like carbon nanotubes found in samples from the Allende carbonaceous chondrite using high-resolution transmission electron microscopy (HRTEM). A highlyExpand


Fullerenes in Allende meteorite
It is reported that fullerenes are in fact present in trace amounts in the Allende meteorite, and many polycyclic aromatic hydrocarbons (PAHs) are detected, consistent with previous reports. Expand
C60: Buckminsterfullerene
During experiments aimed at understanding the mechanisms by which long-chain carbon molecules are formed in interstellar space and circumstellar shells1, graphite has been vaporized by laserExpand
Meteorites and the early solar system
The present work discusses topics in the source regions for meteorites, their secondary processing, irradiation effects on meteorites, solar system chronology, the early solar system, the chemistryExpand
