    Abstract: A method of synthesizing magnetic nanoparticles comprising soft magnetic phases is provided, wherein the method comprises degassing a first mixture at a temperature in a range from about 80° C. to 130° C. The first mixture comprises a solvent, a compound comprising iron, cobalt, or combinations thereof dissolved in the solvent, and an organic component comprising a fatty acid or an amine. Degassing the first mixture is followed by adding a capping ligand to the first mixture under inert atmosphere to form a second mixture; adding a reducing agent to the second mixture at a temperature in a processing temperature range from about 250° C. to about 350° C. to form a third mixture; and incubating the third mixture at a temperature within the processing temperature range to form nanoparticles comprising a soft magnetic phase.

    Abstract: A method and apparatus for generating latent heat at low temperatures using an exothermic salt crystallization reaction in a supersaturated solution. The method and apparatus includes a supersaturated solution including a salt-based solute in a solvent. In an embodiment, the supersaturated solution is comprised of a salt-based solute of at least 50 wt. % sodium acetate trihydrate in a solvent of 70 vol. % ethylene glycol and 30 vol. % water. The supersaturated solution remains stable at a temperature below a melting point of the salt-based solute and is triggered to crystallize in a controlled manner to generate latent heat. The method and apparatus further including an actuation component, in fluid communication with a lubricating fluid, to initiate an exothermic crystallization response in the supersaturated solution. The supersaturated solution is suitable for use in a heat exchanger apparatus of an engine. The crystallized salt will re-dissolve at elevated temperatures thus allowing for multiple use cycles.
