A process and an apparatus for converting thermal energy into mechanical energy in a Rankine cycle is provided. The process and apparatus include a working fluid that comprises a fluorinated oxirane. The fluorinated oxirane can contain substantially no hydrogen atoms bonded to carbon atoms and can have from about 4 to about 9 carbon atoms. The process can drive a turbine and, in some embodiments, generate electricity.

Foamable compositions are provided that include at least one blowing agent, at least one foamable polymer or a precursor composition thereof, and a nucleating agent. The nucleating agent includes a fluorinated oxirane which, in some embodiments, can have up to a maximum of three hydrogen atoms. The fluorinated oxiranes can have a total of from about 2 to about 12 carbon atoms. Also provided is a process for preparing a polymeric foam and a composition that includes a blowing agent and a nucleating agent comprising a fluorinated oxirane.
