چکیده
High-resolution transmission electron microscopy, shows that carbon in the Allende carbonaceous chondrite meteorite is predominantly a poorly crystalline graphite. Such material is of interest as an important carrier of the isotopically anomalous noble gases found in carbonaceous chondrites.

Fullerene-like carbon nanostructures in the Allende meteorite
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 faceted graphene sheets with little large scale graphitization, and resembles that of a microporous carbon following high temperature heat treatment. Closed carbon nanoparticles, typically V2^10 nm in diameter are common...
متن کاملThe unextractable organic fraction of the pueblito de allende meteorite: evidence for its indigenous nature.
The Pueblito de Allende meteorite contains only 0.1-0.5 ppm of solvent-extractable carbon, most or all of which is due to terrestrial contamination. Determinations of the total carbon content gives values from 0.23 to 0.35 per cent. The presumed indigenous insoluble carbon is thus present in a ratio of 2300:1 relative to contaminant carbon. A sample of the meteorite was extracted with a deutera...
متن کاملA density functional study on the mechanical properties of metal-free two-dimensional polymer graphitic Carbon-Nitride
Successful synthesis of the stable metal-free two-dimensional polymer graphitic carbon-nitride with remarkable properties has made it as one of the most promising nanostructures in many novel nanodevices, especially photocatalytic ones. Understanding the mechanical properties of nanostructures is of crucial importance. Thus, this study employs density functional theory (DFT) to obtain the mecha...
متن کاملSynthesis and Electrochemical Study of Nano Graphitic Mesoporous Carbon
In the present study, a type of graphitic mesoporous carbon (denoted as GMC) is synthesized and its structural properties were characterized by nitrogen physisorption isotherms, transmission electron microscopy and Raman spectroscopy. According to BET and BJH methods, the specific surface area (SBET) and the average pore diameter of GMC are estimated to be 720 m2/g and 3.4 nm, respectively....
