A galvanic cell and methods of using the galvanic cell is described for the recovery of uranium from used nuclear fuel according to an electrofluorination process. The galvanic cell requires no input energy and can utilize relatively benign gaseous fluorinating agents. Uranium can be recovered from used nuclear fuel in the form of gaseous uranium compound such as uranium hexafluoride, which can then be converted to metallic uranium or UOand processed according to known methodology to form a useful product, e.g., fuel pellets for use in a commercial energy production system.

A heat transfer fluid created from nanoparticles that are dispersed into an ionic liquid is provided. Small volumes of nanoparticles are created from e.g., metals or metal oxides and/or alloys of such materials are dispersed into ionic liquids to create a heat transfer fluid. The nanoparticles can be dispersed directly into the ionic liquid during nanoparticle formation or the nanoparticles can be formed and then, in a subsequent step, dispersed into the ionic liquid using e.g., agitation.

A process of forming a hydrogen storage material, including the steps of: providing a borohydride material of the formula: M(BH)where M is an alkali metal or an alkaline earth metal and 1&#x2266;x&#x2266;2; providing an alanate material of the formula: M(AlH)where Mis an alkali metal or an alkaline earth metal and 1&#x2266;x&#x2266;2; providing a halide material of the formula: MHalwhere Mis an alkali metal, an alkaline earth metal or transition metal and Hal is a halide and 1&#x2266;x&#x2266;4; combining the borohydride, alanate and halide materials such that 5 to 50 molar percent from the borohydride material is present forming a reaction product material having a lower hydrogen release temperature than the alanate material.
