carbon copy

1. A copy of a document that is made by placing a sheet of carbon paper under the original so that the print gets transferred from the original to the sheet of paper below it. Carbon copies are largely obsolete but are still used in some cases for receipts. Could you please make a carbon copy of that invoice? I need it for my records.
2. To include additional recipients on an email message that is intended for, or directed to, another person. Often abbreviated as "cc." Please carbon copy me on that email to Janice. I want her to know I am aware of the situation.
3. A person or thing that closely resembles someone or something else in looks or attributes. Even though they were born several years apart, Darren is a carbon copy of his brother. They have the same gait, mannerisms, and hairstyle.

carbon copy

A person or thing that closely resembles another, as in Our grandson is a carbon copy of his dad. Originally this term meant a copy of a document made by using carbon paper. The linguistic transfer to other kinds of duplicate survived the demise of carbon paper (replaced by photocopiers, computer printers, and other more sophisticated devices). [c. 1870]

a carbon copy

COMMON If one person or thing is a carbon copy of another, the two people or things are identical, or very similar. Hugh was a carbon copy of his father, Edward; both had the same blond hair and easy charm. The town, almost a carbon copy of Gualdo, is best known for its mineral waters. Note: A carbon copy of a document is an exact copy of it which is made using carbon paper.

carbon copy

a person or thing identical or very similar to another.
The expression comes from the idea of an exact copy of written or typed material made by using carbon paper.

a ˌcarbon ˈcopy

a person or thing that is exactly or extremely like another: The recent robberies in Leeds are a carbon copy of those that have occurred in Halifax over the last few months.
A carbon copy is a copy of a document, letter, etc. made by placing carbon paper (= thin paper with a dark substance on one side) between two sheets of paper.

carbon copy

Also, cc. An exact duplication. The original carbon copy, long used for correspondence and other written materials, was made by placing a sheet of carbon paper between two sheets of paper, the top one to be copied onto the blank bottom sheet by pressure from a pen, typewriter, or other instrument. Although this type of duplication has become largely obsolete, replaced by photocopying and electronic printers, it survives in the abbreviation cc, used to signal additional recipients of a letter or e-mail. A 1981 film, Carbon Copy, uses the term in the figurative sense; in it a white man discovers he has a black son who wants to be adopted.

carbon footprint

The total contribution of carbon dioxide and other greenhouse gases by a particular activity, enterprise, or product. The increasing concern about the harmful effect of human activity on the environment has promoted the use of this term, which may soon be a cliché. The Boston Globe travel section headlined an article on “green” (ecologically harmless) vacations: “Leave Your Carbon Footprint at Home” (June 6, 2010). Gregg Hurwitz’s novel They’re Watching (2010) has the lines, “‘What’s a lifestyle coach do, exactly?’ I asked. ‘We’re working on reducing Keith’s carbon footprint.’”

The Abrasion Index method yields reproducible data, even in the case of highly durable carbons. This is partly caused by the fact that it directly measures the fines formed, rather than measuring the decrease of the granular carbon mass (which is much less accurate for durable carbons, as it involves the subtraction of two almost identical weights).
The use of carbon additives, generally bituminous coal, in an iron foundry's green sand mixture is common practice to reduce adhering sand grains and improve casting surface finish.
The reaction that converts coal and biomass to alkanes, however, produces carbon chains of many lengths.
Carbon black margins remain low, despite recent price increases and higher sales volumes, according to the sponsor.
New experimental evidence suggests that at high temperatures large carbon clusters form and then collapse into a more stable fullerene configuration.
Such useful properties suggest that scientists should start looking for fragments of these molecules in the soot generated during fullerene production, says Veit Elser, whose group at Cornell University studied a theoretical molecule containing 216 carbon atoms.
Other researchers are pursuing more exotic applications: using fullerenes as molecular cages to hold other materials or modifying them by substituting other atoms for the carbons in these cages.
The burning of coal, oil and natural gas each year spews about 5.3 billion tons of carbon into the atmosphere in the form of carbon dioxide.
This earns Annex I countries or their corporations carbon credits, which can be put toward their target reductions.
Unlike the fluorescent colors of quantum dots, the colors emitted by the new carbon dots depend on the color of light that the researchers use to excite them.
Attendees of Carbon Black World 2004 will receive a complete briefing on market trends by region and sector, new technologies, international regulatory issues and technical trends in major end-use markets such as tires, industrial rubbers and others.
Carbon sequestration is a third alternative to reduce GHG emissions.
Many scientists see sequestering carbon in biotic "sinks" such as forests and farmlands in the terrestrial biosphere as a win--win proposition for the environment--"a way to improve the atmosphere while doing things you ought to be doing anyway, like protecting natural resources and promoting sustainable development," says Gregg Marland, a research scientist and expert in carbon sequestration at Oak Ridge National Laboratory in Tennessee.
Trace gases, such as carbon dioxide (C0C[O.SUB.2]), methane, nitrous oxide, ozone, and chlorofluorocarbons, allow light from the sun to pass through our atmosphere to the Earth but have a tendency to reflect longer-wave heat rays that might otherwise escape back into the upper atmosphere.
