There are herein described phase change materials containing sodium acetate trihydrate having improved homogeneity, a process for the preparation of said materials, and their utility in phase change systems. More particularly, the present invention relates to the use of phase change compositions comprising sodium acetate trihydrate, at least one alkali soluble polymer for inhibition of sodium acetate anhydrous crystal formation in sodium acetate trihydrate containing phase change materials, and at least one sodium acetate trihydrate nucleation promoter, and, if a lower phase change temperature is required, at least one melting point depressing agent.

A fluoropropene composition comprising E-1,3,3,3-tetrafluoropropene, 1,1,3,3,3-pentafluoropropene, and 2,3,3,3-tetrafluoropropene, wherein the total amount of 1,1,3,3,3-pentafluoropropene and 2,3,3,3-tetrafluoropropene is 1.0 wt. % or less, based on the total weight of the fluoropropene composition. A method of producing the fluoropropene, composition and methods for using the fluoropropene composition are also disclosed.

In one aspect, compositions are described herein. In some embodiments, a composition comprises a latent heat storage material having a solid-to-gel transition between about ?50? C. and about 100? C. at 1 atm. In some embodiments, a composition comprises a foam and a latent heat storage material dispersed in the foam, the latent heat storage material having a solid-to-gel transition between about ?50? C. and about 100? C. at 1 atm.

Methods, systems, and devices for making a solid utilizing thermal recuperation are provided in accordance with various embodiments. Some embodiments include a method that includes combining a first material in a frozen state with a portion of a freeze point suppressant. The method may include utilizing the combined first material with the portion of the freeze point suppressant to freeze a second material. Some embodiments include combining the second material in the frozen state with another portion of the freeze point suppressant. Combining the first material in the frozen state with the portion of the freeze point suppressant may melt the first material and may form the first material in a liquid state combined with the portion of the freeze point suppressant; the combined first material in the liquid state with the freeze point suppressant has a temperature lower than a temperature of the first material in the frozen state.
