The increasing atmospheric burden of the greenhouse gas sulfur hexafluoride (SF6)
Atmospheric Chemistry and Physics, 2020 . We report a 40-year history of SF6 atmospheric mole fractions measured at the Advanced Global Atmospheric Gases Experiment (AGAGE) monitoring sites, combined with archived air samples, to determine emission estimates from 1978 to 2018.

Recent and future trends in synthetic greenhouse gas radiative forcing [PDF]
, 2013 Atmospheric measurements show that emissions of hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons are now the primary drivers of the positive growth in synthetic greenhouse gas (SGHG) radiative forcing. We infer recent SGHG emissions and examine the

The black silicon method II: the effect of mask material and loading on the reactive ion etching of deep silicon trenches [PDF]
, 1994 Very deep trenches in Si with smooth controllable profiles are etched using a fluorine-based Reactive Ion Etcher(RIE). The effect of various mask materials and loading on the profile is examined using the Black Silicon Method. It is found that most metal

The Development of SF6 Green Substitute Gas
Sustainability, 2021 Due to its high greenhouse effect, the use of SF6 as the main insulating gas is restricted in the electric power field. Along with the aim of environmental protection, the search for new alternative gases with a lower greenhouse effect and higher ...
