Esempi di utilizzo di CFCS in una frase

• The main causes of ozone depletion and the ozone hole are manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants, and foam-blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons), referred to as ozone-depleting substances (ODS).
• Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are fully or partly halogenated hydrocarbons that contain carbon (C), hydrogen (H), chlorine (Cl), and fluorine (F), produced as volatile derivatives of methane, ethane, and propane.
• He played a major role in developing leaded gasoline (tetraethyl lead) and some of the first chlorofluorocarbons (CFCs), better known in the United States by the brand name Freon; both products were later banned from common use due to their harmful impact on human health and the environment.
• Scientists conducted experiments from NASA experimental aircraft and proved that atmospheric chemicals such as the chlorofluorocarbons (CFCs) released from refrigerants and aerosol sprays did destroy ozone.
• This study soon led to research into chlorofluorocarbons (CFCs), apparently harmless gases that were used in refrigerants, aerosol sprays, and the making of plastic foams.
• Most OH and NO are naturally present in the stratosphere, but human activity - especially emissions of chlorofluorocarbons (CFCs) and halons - has greatly increased the concentration of Cl and Br, leading to ozone depletion.
• Volatile organic compounds (VOCs) – Organic compounds which typically have a boiling point less than or equal to 250 °C; for example chlorofluorocarbons (CFCs) and formaldehyde.
• The Washington Post reported a factual error regarding a leak of false information by a State Department staffer, which the staffer falsely attributed to Hodel, that rather than reduce the production of CFCs to prevent ozone layer destruction, people should wear hats and use sunscreen.
• In order to aid the recovery of the stratospheric ozone layer, HFCs were adopted to replace the more potent chlorofluorocarbons (CFCs), which were phased out from use by the Montreal Protocol, and hydrochlorofluorocarbons (HCFCs) which are presently being phased out.
• Analyses of air trapped in snow since the late 19th century have confirmed that non-industrial sources of the CFCs, halons, and major chlorocarbons were insignificant.
• In 1974 University of California at Irvine chemist Frank Sherwood Rowland suggested that long-lived organic halogen compounds, such as the CFCs then widely used to pressurize spray cans, would reach the stratosphere where they would be dissociated by UV light, releasing chlorine atoms.
• Depending on the refrigerants used, these installations and their subsequent leaks can lead to ozone depletion (chlorinated refrigerants like CFCs and HCFCs) and/or climate change, by exerting an additional greenhouse effect (fluorinated refrigerants: CFCs, HCFCs and HFCs).
• The most prominent academic members were US scientists known for denial of global warming and the relationship between Chloro Fluoro Carbon or CFCs and the ozone depletion.
• Especially powerful greenhouse gases, such as sulfur hexafluoride, chlorofluorocarbons (CFCs), or perfluorocarbons (PFCs), have been suggested both as a means of initially warming Mars and of maintaining long-term climate stability.
• Vacuum plasma spraying (VPS) is a technology for etching and surface modification to create porous layers with high reproducibility and for cleaning and surface engineering of plastics, rubbers and natural fibers as well as for replacing CFCs for cleaning metal components.
• Parshall also directed the development of alternatives to the chlorofluorocarbons (CFCs) used in refrigerators and air conditioners.
• Unlike CFCs used as refrigerants, trifluoroethane has no chlorine atoms and therefore is not ozone-depleting.
• This is a new generation eco-friendly foam blowing agent that is free of Chlorofluorocarbons (CFCs), Hydrochlorofluorocarbons (HCFCs), and Hydrofluorocarbons (HFCs) based on naturally occurring methyl methanoate.
• Otkin and Martin identified three types of kona storms: cold-frontal cyclogenesis cyclones (CFCs), trade wind easterlies, and cold-frontal cyclogenesis/trade wind easterlies cyclones.
• Use of chlorofluorocarbons (CFCs) in refrigeration systems, and use of CFCs and halons in fire suppression systems and manufacturing processes.
