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.

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

Black Carbon and the Carbon Cycle
Science, 1998When vegetation and fossil fuels burn, the combustion creates "black carbon" that becomes distributed throughout the environment. Determining how it is created and where it goes is important for studying the past history of fire and for understanding global carbon and oxygen budgets.

Journal of Energy Chemistry, 2013
Supercapacitors, or electrochemical capacitors, are a power storage system applied for harvesting energy and delivering pulses during short periods of time. The commercially available technology is based on charging an electrical double-layer (EDL), and using high surface area carbon electrodes in an organic electrolyte.

Materials Science and Engineering: A, 1997
Abstract A problem in the production of carbon-carbon composites from carbon fiber reinforced thermoset composites through pyrolization is the cracking of the matrix due to internal stresses caused by the large shrinkage of the pyrolizing matrix and the simultaneous expansion of the fibers.

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).
