Abstract: A rotor for a reluctance machine includes a rotor body having cavities defined by inner surfaces of the rotor body, a filler disposed within the cavities, and an adhesive coating that covalently bonds the filler to the inner surfaces of the rotor body. The adhesive coating exhibits a composite structure including a continuous matrix component and a discontinuous organic component dispersed throughout the matrix component, wherein the matrix component comprises an inorganic siloxane network and the organic component comprises a plurality of organic groups bonded to the inorganic siloxane network. The adhesive coating is formed on the inner surfaces of the rotor body by depositing a precursor composition on the inner surfaces of a rotor body and exposing the precursor composition to a plasma. The precursor composition comprises an organofunctional silane or a hydrolysate thereof.

Abstract: A passive cooling system for battery cells includes a housing defining a cavity with a plurality of battery cells disposed in the cavity. Each of the battery cells is surrounded by a porous media and a phase change material is disposed within spaces defined by the porous media. A cold plate is disposed at a top of the cavity to cool the phase change material that is vaporized and change the vapor to a liquid.
