C4-FN (C4-fluoronitrile, C4FN) is a perfluorinated compound developed as a high-dielectric gas for high-voltage switchgear. [1] It has the structure (CF 3 ) 2 CFC≡N, which can be described as perfluoro isobutyronitrile , falling under the category of PFAS , or per- and polyfluoroalkyl substances.
TGOR – total gas oil ratio (GOR uncorrected for gas lift gas present in the production fluid [citation needed]) TH – tubing hanger; THCP – tubing hanger crown plug; Thr/Th# – thruster ('#'- means identification letter/number of the equipment, e.g. thr3 or thr#3 means "thruster no. 3" [citation needed]) THD – tubing head; THERM ...

A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board.The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15.
The C7 series of firearms is driven by the same Stoner bolt and carrier gas system as the M16 series. Like the M16A1 and M16A3 , the C7 has both semi-automatic and fully automatic fire modes. The C7 also features the structural strengthening, spent case deflector, improved handguards, and longer stock developed for the M16A2.
I tried 11 C4 flavors and ranked them based on taste and flavor. Here are my findings. C4 provided samples of the Performance Energy line for this review. Prices and availability are subject to ...
The results of 100 °C heat test are: 0.13% loss in the first 48 hours, no loss in the second 48 hours, and no explosions in 100 hours. The vacuum stability test at 100 °C yields 0.2 cubic centimeters of gas in 40 hours. Composition C-4 is essentially nonhygroscopic. [7] The shock sensitivity of C-4 is related to the size of the nitramine ...
Tetrafluoromethane is a potent greenhouse gas that contributes to the greenhouse effect. It is very stable, has an atmospheric lifetime of 50,000 years, and a high greenhouse warming potential 6,500 times that of CO 2. [10] Tetrafluoromethane is the most abundant perfluorocarbon in the atmosphere, where it is designated as PFC-14.
