• CFC (noun)

Sense 1

Meaning:

A fluorocarbon with chlorine; formerly used as a refrigerant and as a propellant in aerosol cans

Classified under:

Nouns denoting substances

Synonyms:

CFC; chlorofluorocarbon

Context example:

the chlorine in CFCs causes depletion of atmospheric ozone

Hypernyms ("CFC" is a kind of...):

pollutant (waste matter that contaminates the water or air or soil)

fluorocarbon (a halocarbon in which some hydrogen atoms have been replaced by fluorine; used in refrigerators and aerosols)

greenhouse emission; greenhouse gas (a gas that contributes to the greenhouse effect by absorbing infrared radiation)

Hyponyms (each of the following is a kind of "CFC"):

HCFC; hydrochlorofluorocarbon (a fluorocarbon that is replacing chlorofluorocarbon as a refrigerant and propellant in aerosol cans; considered to be somewhat less destructive to the atmosphere)

Freon (any one or more chlorofluorocarbons (or related compounds) that are used as an aerosol propellant, organic solvent, or refrigerant)

 Context examples 

This protein is a member of the epidermal growth factor (EGF)- Cripto, Frl-1, and Cryptic (CFC) family.

“CFCs have lifetimes from 50 to 100 years, so they linger in the atmosphere for a very long time,” said Anne Douglass, a fellow atmospheric scientist at Goddard and the study’s co-author.

Constitutively expressed during embryogenesis, Cripto belongs to the EGF-CFC family of growth factor-like molecules and plays a key role in signaling pathways of certain transforming growth factor-beta superfamily members; as a TAA, Cripto is overexpressed in carcinomas such as those of the breast, ovary, stomach, lung, and pancreas while its expression is absent in normal tissues.

EGF-CFC family member proteins share a variant EGF-like motif, a conserved cysteine-rich domain, and a C-terminal hydrophobic region.

Looking forward, the Antarctic ozone hole should continue to recover gradually as CFCs leave the atmosphere, but complete recovery will take decades.

(First Direct Proof of Ozone Hole Recovery Due to Chemicals Ban, NASA)

CFCs are long-lived chemical compounds that eventually rise into the stratosphere, where they are broken apart by the Sun’s ultraviolet radiation, releasing chlorine atoms that go on to destroy ozone molecules.

Later amendments to the Montreal Protocol completely phased out production of CFCs.

This study is the first to use measurements of the chemical composition inside the ozone hole to confirm that not only is ozone depletion decreasing, but that the decrease is caused by the decline in CFCs.

(First Direct Proof of Ozone Hole Recovery Due to Chemicals Ban, NASA)

Measurements show that the decline in chlorine, resulting from an international ban on chlorine-containing manmade chemicals called chlorofluorocarbons (CFCs), has resulted in about 20 percent less ozone depletion during the Antarctic winter than there was in 2005 — the first year that measurements of chlorine and ozone during the Antarctic winter were made by NASA’s Aura satellite.
