composition, heat transfer and mechanical power generation devices, use of a composition, blowing agent, foam, and methods for cooling an article, for heating an article, for extracting a substance from biomass and a material from a matrix solid particulate matter, to clean an article, to retrofit a heat transfer device, to reduce environmental impact, to prepare a composition and / or heat transfer device, and to generate greenhouse gas emission credit. The invention provides a heat transfer composition consisting essentially of from about 62 to about 78% by weight of trans-1,3,3,3-tetrafluoropropene (r-1234ze (e)) and from about 22 to about 78%. 38 wt% 1,1-difluoroethane (r-152a). The invention also provides a heat transfer composition comprising from about 20 to about 40 wt% of r-152a, from about 5 to about 55% of r-134a, and from about 5 to about 75%. wt% of r-1234ze (e).
