Carbon–carbon coupling in biotransformation
Current Opinion in Biotechnology, 2003Most research on carbon-carbon coupling biocatalysts is still carried out on aldolases and ketolases from carbohydrate metabolism; the emphasis of these studies is on the synthesis of optically active compounds. A major target is to avoid expensive starting materials and to broaden the range of possible products.

Carbon-Carbon Composites [PDF]
, 1998 Carbon-carbon (CC) materials are a generic class of composites similar to the graphite/epoxy family of polymer matrix composites. These materials can be made in a wide variety of forms, from one-dimensional to n-dimensional, using unidirectional tows, tapes, or woven cloth (Fig. 15.1).

Since their introduction in the early 1970’s, carbon fibre reinforced carbon (CC) composites have become a well-established form of engineering carbon and find widespread application in both aerospace and materials processing industries. In fact, CC composites are notable as being among the most successful of the “brittle matrix composite” engineering ...

The effect of carbon-chain oxygenation in the carbon-carbon dissociation
Journal of Molecular Modeling, 2018Currently, there is a trend of moving away from the use of fossil fuels to the use of biofuels. This modification changes the molecular structure of gasoline and diesel constituents, which should impact pollutant emissions and engine efficiency. An important property of automotive fuels is the resistance to autoignition. The goal of the present work is

Honeycomb carbon: a review of graphene.
Chemical Reviews, 2010Graphene is the name given to a two-dimensional sheet of sp2-hybridized carbon. Its extended honeycomb network is the basic building block of other important allotropes; it can be stacked to form 3D graphite, rolled to form 1D nanotubes, and wrapped to ...
