Abstract: A liquid electrolyte composition obtainable by combining a first component comprising bistrifluoromethanesulfonimide and/or an analogue thereof with a second component comprising a dialkyl sulfone, diaryl sulfone, alkyl aryl sulfone, alkyl acyl sulfone, boric acid, alkyl boronic acid, aryl boronic acid, dialkyl phosphite, trialkyl phosphite, dialkyl phosphate, trialkyl phosphate, alkylene carbonate, alkanoic lactone, preferably alkanoic ?-lactone an analogue of any of these, or mixtures thereof, wherein any of the alkyl, aryl of alkenyl groups may be substituted or unsubstituted. The liquid electrolyte is used in an electrochemical gas sensor.

Abstract: An internal support member for a shrink wrapped package of identical articles arranged in a layer or layers on a base comprises a single generally rectangular sheet of relatively rigid material formed with at least two preferably six parallel folds that extend vertically when the sheet is stood on edge on the base. The folds define compressive load-bearing side portions which are disposed longitudinally and laterally between the articles in the layer to provide a stable non-tilting support for a similar package stacked thereon.
