Exempel på hur man kan använda HYDROFLUOROCARBONS i en mening

• These include chlorofluorocarbons and hydrofluorocarbons, both of which cause ozone depletion (although the latter much less so) and contribute to global warming.
• The exchange traded in emissions of six gases: carbon dioxide, methane, nitrous oxide, sulfur hexafluoride, perfluorocarbons and hydrofluorocarbons.
• Common duster gases include hydrocarbon alkanes, like butane, propane, and isobutane, and hydrofluorocarbons like 1,1-difluoroethane, 1,1,1-trifluoroethane, or 1,1,1,2-tetrafluoroethane which are used because of their lower flammability.
• Several other primary gases also include methane, nitrous oxide, sulfur hexafluoride, perfluorocarbons, and hydrofluorocarbons.

• (1) energy — eliminating fossil fuels and shifting to renewables;
  (2) short-lived air pollutants — slashing black carbon (soot), methane, and hydrofluorocarbons;
  (3) nature — restoring and permanently protecting Earth's ecosystems to store and accumulate carbon and restore biodiversity;
  (4) food — switching to mostly plant-based diets, reducing food waste, and improving cropping practices;
  (5) economy — moving from indefinite GDP growth and overconsumption by the wealthy to ecological economics and a circular economy, in which prices reflect the full environmental costs of goods and services; and
  (6) human population — stabilizing and gradually reducing the population by providing voluntary family planning and supporting education and rights for all girls and young women, which has been proven to lower fertility rates.

• Short-lived climate pollutants include methane, hydrofluorocarbons (HFCs), tropospheric ozone and black carbon.
• With the development of the chlorofluorocarbons (along with the succeeding hydrochlorofluorocarbons and hydrofluorocarbons), that came to replace the use of toxic ammonia gas, the refrigerator replaced the icebox, though icebox is still sometimes used to refer to mechanical refrigerators.
• 150 nations meeting at the UNEP summit in Rwanda agree to phase out hydrofluorocarbons (HFCs), as an extension to the Montreal Protocol.
• The protocol, if ratified, would commit nations to roll back emissions of six greenhouse gases (carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride) below 1990 levels.
• While developing country Parties to the Montreal Protocol are allowed to delay their phasedown of climate-forcing and ozone-depleting hydrofluorocarbons (HFCs) during a multi-year grace period consistent with the principal of common but differentiated responsibilities and respective capabilities, there are advantages to earlier implementation when superior alternatives are already available at reasonable costs, as is the case for many uses of HFCs today.
• HCFCs in turn are being phased out under the Montreal Protocol and replaced by hydrofluorocarbons (HFCs), which do not contain chlorine atoms.
• Two alternative types of refrigerant, hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons (HCFCs), also lost favor when they were identified as greenhouse gases (additionally, HCFCs were found to be more damaging to the ozone layer than originally thought).
• Another area of concern is that of ozone-depleting substances such as chlorofluorocarbons (CFCs) and hydrofluorocarbons (HFCs), which are often potent greenhouse gases with serious global warming potential (GWP).
• Deese spearheaded the administration's effort to ratify the Paris Agreement and to reach a global agreement to phase down hydrofluorocarbons (HFCs) through the Kigali Amendment to the Montreal Protocol.
• The six Kyoto Protocol GHGs are covered (carbon dioxide, methane, nitrous oxide, sulphur hexafluoride, hydrofluorocarbons and perfluorocarbons).
• Unlike traditional hydrofluorocarbons (HFCs) and chlorofluorocarbons (CFCs), which are saturated, HFOs are olefins, otherwise known as alkenes.
• They are divided into several types, the main of those are hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulphur hexafluoride (SF6).
• Fluorine continued to play a role in refrigeration though: hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs) were developed as replacement refrigerants.
• His notable discoveries include: zeolites as precursors to electronic ceramics, new Bi and Tl-containing superconductors, catalysts for Fischer-Tropsch synthesis, and hydrofluorocarbons (HFCs), colossal dielectrics (CCTO), colossal magnetoresistance (GMR) oxides, and skutterudite thermoelectrics.
