GAS GRAB  Carbon honeycomb is a three-dimensional cluster of carbon sheets. If researchers can succeed in creating a neat orderly honeycomb structure (illustrated above), the material might be able to store unusually high amounts of gas molecules, including xenon (red), krypton (brown) or carbon dioxide (blue). 

Researchers have identified a mysterious lab-made material as a new form of carbon.  

Carbon honeycomb, a three-dimensional cluster of carbon sheets, can trap large amounts of gas within six-sided cells. The newly described structure could be used to store gases or liquids, or as a building material for more complex compounds, Ukrainian researchers report February 5 in Physical Review Letters.

Electron microscope images helped uncover the new structure, which was first created in 2009 by vaporizing thin carbon spindles in a vacuum. Subsequent tests of the nanometers-thick film revealed that the substance had different density and light-scattering properties than known forms of carbon like graphite or fullerenes. Carbon honeycomb cells might link up with cylindrical carbon nanotubes, the researchers say, but unlike nanotubes, the new structure holds up for months in a
