Journal ArticleDOI

Synthesis and solid-state NMR structural characterization of 13C-labeled graphite oxide.

TL;DR: The detailed chemical structure of graphite oxide (GO), a layered material prepared from graphite almost 150 years ago and a precursor to chemically modified graphenes, has not been previously resolved because of the pseudo-random chemical functionalization of each layer, as well as variations in exact composition.
Journal ArticleDOI

Comet 81P/Wild 2 under a microscope.

Donald E. Brownlee, +185 more
- 15 Dec 2006 - 
TL;DR: The Stardust spacecraft collected thousands of particles from comet 81P/Wild 2 and returned them to Earth for laboratory study, and preliminary examination shows that the nonvolatile portion of the comet is an unequilibrated assortment of materials that have both presolar and solar system origin.
Journal ArticleDOI

Mineralogy and petrology of comet 81P/wild 2 nucleus samples

Michael E. Zolensky, +75 more
- 15 Dec 2006 - 
TL;DR: The bulk of the comet 81P/Wild 2 samples returned to Earth by the Stardust spacecraft appear to be weakly constructed mixtures of nanometer-scale grains, with occasional much larger ferromagnesian silicates, Fe-Ni sulfides,Fe-Ni metal, and accessory phases.
Journal ArticleDOI

Organics captured from comet 81P/Wild 2 by the Stardust spacecraft.

TL;DR: The presence of deuterium and nitrogen-15 excesses suggest that some organics have an interstellar/protostellar heritage and a diverse suite of organic compounds is present and identifiable within the returned samples.
Journal ArticleDOI

Isotopic Compositions of Cometary Matter Returned by Stardust

TL;DR: Hydrogen, carbon, nitrogen, and oxygen isotopic compositions are heterogeneous among comet 81P/Wild 2 particle fragments; however, extreme isotopic anomalies are rare, indicating that the comet is not a pristine aggregate of presolar materials.
