Provided is a composition comprising at least one halogenated compound selected from the group consisting of C3-C5 hydrofluoroolefin, CF3I, and combinations thereof, and an effective stabilizing amount of a sesquiterpene selected from the group consisting of farnesol, farnesene, and mixtures thereof. Conventional designs for differential input pairs, though, may not be suitable for emerging technology transistors, such as graphene transistors, carbon nanotube transistors, or other ambipolar transistors. The base portion of the weather strip includes an inserting part adapted to be inserted in the channel and a holding part for holding one of the side walls with the inserting part.
