Abstract: A method to enhance the performances of cooling devices based on barium titanate (BT) ceramics is disclosed. Such cooling is realized by utilizing at least one BT-based ceramics which exhibit large electrocaloric effect (ECE). The method enhances the large ECE performances to cover temperature range between ?30 C to 80C, by introducing an invariant critical point where paraelectric phase and at least one ferroelectric phase of BT-based ceramic refrigerant coexist.

Abstract: A regenerative electrocaloric (EC) device is provided. The regenerative EC device uses a special configuration to expand the temperature span Th-Tc, thereby increasing the cooling power and improving the efficiency thereof. The EC regenerative cooling device includes two electrocaloric effect (ECE) elements/rings in direct thermal contact with each other. The two rings rotate in opposite directions and are divided into multiple sections with an electric field or electric fields applied to every other region/section and an electric field or electric fields removed from remaining sections.

Abstract: Cooling devices, heat pumps, and climate controlling devices employing an electrocaloric composite of high thermal conductivity and significant electrocaloric effect are disclosed. The electrocaloric composites include a combination of one or more EC-fluoropolymers and their blends with one or more electric-insulating fillers of high thermal conductivity.

Abstract: The present teachings describe a solubility prediction approach that is based, in part, upon quantitative-structure property relationships (QSPR). In various embodiments, the solubility prediction methodology comprises identifying a reduced descriptor set from which a solubility equation is derived. The descriptors used in the solubility equation are based upon simplified structural and molecular features which facilitate researcher understanding and solubility model refinement. Moreover, the present teachings provide solubility prediction relationships that may be used to rapidly screen large libraries or collections of compounds.
