to minimize the release of SF6 into the environment. Possible solutions are to use other gases or gas mixtures containing a lower content of SF6. In this regard, SF6-N2 gas mixtures, containing different percent- ages of SFb, have been found to be a good [l].

Highly selective adsorption of SF6 over N2 in a bromine …

We have systematically synthesized a series of functionalized UiO-66-X (X = NO 2, NH 2, Cl, Br, I, Br 2) compounds to further improve the selective SF 6 adsorption of UiO-66, which is one of the best-performing adsorbents, and to investigate the effect of the

Mixtures - UPM

Mixtures 4 Under the influence of external force fields like gravity, centrifugation or electromagnetic fields, all mixtures settle (see Mixture settling), but we here assume, as implicitly done in two-phase mixtures of pure substances, that they are either unsettled or
