Webster's Revised Unabridged Dictionary
    • Carbon process (Photog) A printing process depending on the effect of light on bichromatized gelatin. Paper coated with a mixture of the gelatin and a pigment is called carbon paperorcarbon tissue. This is exposed under a negative and the film is transferred from the paper to some other support and developed by washing (the unexposed portions being dissolved away). If the process stops here it is called single transfer; if the image is afterward transferred in order to give an unreversed print, the method is called double transfer.

In science:

The relative importance of the two processes is determined by the (real-space) range of the two-particle interaction, which in turn is set by the screening properties of the “environment”, e.g. the substrate on which the carbon nanotube is placed.

Graphene coatings: An efficient protection from oxidation
Ideally, one would want to look for primordial helium in regions where the stellar processing is minimal, i.e., in regions where the abundances of elements such as carbon, nitrogen and oxygen are very low.
Big Bang Nucleosynthesis
It is suggested, therefore, that a process that has caused the mixing of carbon to the surface of these stars cannot act in a wide binary system.
The R Stars: Carbon Stars of a Different Kind
The excess carbon has to come from some other process.
The R Stars: Carbon Stars of a Different Kind
The N, S, barium, CH, sgCH, and dwarf carbon stars all have significantly enhanced abundances of the s process elements relative to iron (e.g., Lambert 1985; Green and Margon 1994).
The R Stars: Carbon Stars of a Different Kind
The N stars and many of the S stars are assumed to have undergone helium-shell flashing on the asymptotic giant branch (AGB), and the third dredge-up phase has brought carbon and s process elements to the surface (e.g., see Iben and Renzini 1983).
The R Stars: Carbon Stars of a Different Kind
The lack of s process enhancement, and low luminosity led Dominy (1984) to conclude that the R stars probably received their enhanced carbon from the helium-core flash at the tip of the first ascent giant branch.
The R Stars: Carbon Stars of a Different Kind
It appears very likely that some process that produces carbon in the atmospheres of R stars cannot operate in a binary system, or alternatively, causes any original binary companion to disappear.
The R Stars: Carbon Stars of a Different Kind
The subgiant and dwarf carbon-related stars that have been analyzed all have enhanced s process elements (Green and Margon 1994; Bond, private communication), unlike the R stars.
The R Stars: Carbon Stars of a Different Kind
The nitrogen enhancement can be explained by the mixing process during the previous RGB evolutionary state but the undepleted carbon abundance is hard to understand if mixing has occurred.
CN and CH Band Strengths of Bright Giants in M3
However the fact that most globular cluster CH stars are found not to have enhanced abundances of s-process elements leads to the conclusion that their anomalous carbon abundances or abnormally strong CH absorptions are due to incomplete CN processing (Vanture and Wallerstein 1992).
CN and CH Band Strengths of Bright Giants in M3
Therefore the origin of the enhanced abundances of carbon and s-process elements has been a puzzle, since stars of 0.8 M⊙ may not experience the third dredge-up mechanism during their ascent of the asymptotic giant branch (Iben 1975).
CN and CH Band Strengths of Bright Giants in M3
Among the nucleosynthetic production sites to be considered are the asymptotic giant branch (AGB) stars which are potentially efficient producers of carbon, nitrog en and s-process elements (Jehin et al., 1999).
