New Forms of Carbon

In the late 1960s El Goresy and Donnay [17] discovered a new form of carbon which they called white carbon or Chaoite in a carbon-rich gneiss in the Ries meteorite crater in Bavaria. Chaoite has an hexagonal crystal stmcture and it... 

Recently, Tanuma and Palnichenko [24] have reported a new form of carbon which they call Carbolite formed by quenching high temperature carbon vapour onto a metal substrate. Hexagonal Carbolite I was formed from an Ar-rich gas a rhombohedral form, Carbolite II, was formed from an Ar-Hj gas mixture. 

R. F. Curl (Rice University, Texas), H. Kroto (Sussex University) and R. E. Smalley (Rice University, Texas) discovery of a new form of carbon, the fullerenes. 

A new form of carbon coating is now available which is neither diamond nor graphite and is known as diamond-like carbon (DLC).bl DLC can be considered as a metastable carbon produced as a thin coating with a broad range of structure and composition.l b[42]... 

Kratschmer W, Lamb LD, Fostiropoulos K, Huffman DR (1990) Solid C60 a new form of carbon. Nature 347 354-356. 

Storing hydrogen in a carbon structure is another form of chemical bonding. New forms of carbon structures are currently being researched and promise the best and safest approach as a reversible gas absorption technology. This research is the design and use of carbon nanostractures, either nanotubes or nanofibers. 

Carbons as supports in catalysis and new forms of carbons with atomic scale building blocks... 

No other allotropic forms of carbon were known until ten years ago then arising from studies of interstellar carbonaceous molecules, a new form of carbon, namely fullerene or buckyballs , was discovered (Kroto et al 1985), for which the authors received the 1996 Nobel Prize for Chemistry. Its structure is basically a ball or spherically shaped cage consisting of pure carbon. The most stable... 

Carbon sources make new forms of carbon or change carbon from one form to another. Stars are the only natural sources of newly... 

Scientists continue to explore new forms of carbon for use as raw materials in new products. One of the most interesting fields of research that explores these newly discovered forms is called nanotechnology. Nanotechnology is the science and application of very small things, usually less than 0.00004 inches (1 micrometer) in length. 

Carbon source Something that makes new forms of carbon. 

What do you get when you make an extremely large polynuclear aromatic hydrocarbon, with millions or billions of benzene rings joined together You get graphite, one of the oldest-known forms of pure elemental carbon. Let s consider how aromaticity plays a role in the stability of both the old and the new forms of carbon.
