Perfluorohexane has extremely high global warming potential (GWP) of 9,300. This leads to a need to find low GWP alternative. Novec 649 was considered a good drop-in replacement in many applications due to its similar thermo-physical properties and having a global warming potential of 1.
Fluorinert is the trademarked brand name for the line of electronics coolant liquids sold commercially by 3M.As perfluorinated compounds (PFCs), all Fluorinert variants have an extremely high global warming potential (GWP), [1] so should be used with caution (see below).
Traditional perfluorocarbon (PFC) based compounds used for cooling, such as Fluorinert, display high global warming potentials (GWPs), typically 5,000 to 10,000 times that of CO 2. [1] Novec 649 was chosen as a good drop-in replacement due to it having similar thermo-physical properties to Fluorinert FC-72 ( perfluorohexane , C6F14) while ...
A water sample is measured as part of a PFAS drinking water treatment experiment, Tuesday, Feb. 14, 2023, at the U.S. Environmental Protection Agency Center For Environmental Solutions and ...
The gas is also released by manure, and livestock accounts for about a third of human-related methane emissions, which are collectively responsible for about 30% of global warming.
In order to combat the potential global warming effects of F-gases, and as part of the EU's Kyoto protocol commitments, in 2006 the European Union passed two pieces of legislation controlling their use: the F-gas Regulation (EC) No 842/2006 and the Mobile Air Conditioning Directive Directive 2006/40/EC. The F-gas Regulation adopts an approach ...
World leaders are meeting in Paris this month in what amounts to a last-ditch effort to avert the worst ravages of climate change. Climatologists now say that the best case scenario — assuming immediate and dramatic emissions curbs — is that planetary surface temperatures will increase by at least 2 degrees Celsius in the coming decades.
Nature versus nurture: Scientists are gathering more evidence on which has more of an impact on human well-being amid the aging process. While both environmental exposures and genetics are known ...
