C Sixty Inc. is a private biophaimaceutical company focusing on the discovery and the development of a new class of therapeutics based on the fullerene molecule, a hollow sphere made up of 60 carbon atoms which was discovered in 1985 as the third and unprecedented new form of elemental carbon in nature. It was dubbed buckminsterfullerene or fullerene because of its geodesic character and its discoverers were awarded the 1996 Nobel Prize in chemistry. C Sixty's lead products are based on...
Mechanical Properties of Polymerized Amorphous and Nanocrystalline Carbon
Institute for High Pressure Physics, Russian Academy of Sciences, Troitsk, Moscow region, 142190, Russia Mechanical properties of various carbon phases prepared by the fullerite CM heating in the 3.5 to 13.5 GPa pressure interval with the subsequent quenching have been reviewed, discussing, in particular, the general trends of interrelation between the structure, density, and mechanical properties of carbon materials. Hie considered pressure interval may be conditionally divided into the...

MER Corporation, Tucson, Arizona 85706, USA The recent developments of carbonaceous material synthesis have resulted in several new forms of carbon such as carbon nanotubes and carbon nanofibers, and super-high surface area activated carbons nano-materials. There are speculations that these materials may have extraordinarily high hydrogen storage capacities. In this work, we examined the hydrogen gas adsorption capacities of these carbonaceous materials at room temperature, as well as at liquid...
Fullerene Materials for Lithiumion Battery Applications
aMER Corporation, Tucson, Arizona 85706, USA Fullerene International Corporation, New York, NY 10022, USA Novel and high-performance anode materials based on modified fullerene materials, for lithium-ion rechargeable batteries were developed. The technical feasibility of lithium-ion intercalation and de-intercalation based on the degree of anion or atomic modification of the fullerene was examined. In this approach the fullerene molecule is viewed as a large anchor molecule to which various...
Role of Fullerenelike Structures in the Reactivity of Shungite Carbon as Used
Institute of Geology Karelian Research Center RAS, Pushkinskaya 11, Petrozavodsk 185610, The work highlights a source of unusual high reactivity of shungite carbon ShC as a catalyst in modeling coal-treatment reactions, a filler for polymeric matrices, an adsorbent and filter for a water-purification process, and a reagent in melting of siliceous iron and in the production of silica carbide. The structural pattern of ShC was shown to be connected with fullerene-like structures which could be...
