Abstract: A method of depowdering objects (e.g., heat exchangers) having small and/or complex internal geometries and manufactured using an additive manufacturing technique performed with a powder material. The method includes applying a pressurized fluid to the objects via a pressurized fluid applicator operatively coupled to the object, thereby removing a portion of unbound powder material on or in the object. The method further includes applying vortex vibration to the object via a vortex vibration source operatively coupled to the object, thereby loosening a portion of the unbound powder material remaining on or in the object, and applying the pressurized fluid to the object via the pressurized fluid application, thereby removing a portion of the loosened, unbound powder material from the object. The latter two applying steps are repeated until a specified amount of the unbound powder material has been removed from the object.

Abstract: A remotely controllable sublimation apparatus that includes a crucible block adapted to retain a crucible containing a solid mixture comprising one or more radionuclides, a first heating block comprising one or more first heating elements configured to selectively generate heat having a first temperature sufficient to at least partially sublime the solid mixture, and a collection vessel coupled to the first heating block. The crucible block is movable, relative to the first heating block, between an open position and a closed positon. When the crucible block is in the closed position, the one or more first heating elements are configured to heat the crucible block to the first temperature, thereby heating the solid mixture and producing a vapor that is collected by the collection vessel and leaving a solid residue in the crucible that substantially consists only of the one or more radionuclides.

Abstract: The invention provides an automated method for isolating a targeted isotope, the method having the steps of supplying a dissolved uranium targets into a first reaction environment; precipitating non-targeted isotope within the first reaction environment transferring liquid phase targeted isotope to a second reaction environment; precipitating the liquid phase targeted isotope in the second reaction environment; dissolving the precipitated targeted isotope; transferring the dissolved targeted isotope to a third reaction environment; and precipitating non-targeted isotope (i.e., iodine), such that the targeted isotope remains in the solution. Also provided is an automated system for isolating isotopes, the system having a plurality of reaction environments adapted to pneumatically receive and disgorge reactants and products via remotely actuated valves positioned between each of the reaction environments.

Abstract: A discharged electrochemical cell as described herein comprises an electrochemically reactive metal-containing cathode (e.g., Li, Na, Mg, or Zn; preferably Li) and a layered anode with an electrolyte therebetween. The layered anode comprises a conductive substrate and a reactive film of a metal, a semimetal, a metal oxide, or a semimetal oxide on the surface of the substrate. The reactive film is capable of reversibly alloying with, reversibly forming a mixed phase with, or reversibly reacting with, metal from cathode during charging of cell, and releasing the metal back to the cathode during discharge of the cell.
