  • Publication number: 20110079516
    Abstract: An anode and cathode for an electrolytic cell configured as a low inductance transmission line to enable control of an interphase at an electrode surface. The anode and cathode are coupled to a switched current source by a low inductance path that includes a parallel plate transmission line, a coaxial transmission line, or both. The switched current source provides fast switching between current sources to provide fast charging and discharging of the double-layer capacitance associated with the electrode surface so that an isotope may be selectively transported to the electrode surface for oxidation or reduction. A photon source may be used to create a population of isotope containing species within the electrolyte. An additional static magnetic field and/or an alternating current magnetic excitation source may be used to modify the composition of the population of species containing the isotope to be separated.

  • Publication number: 20100170938
    Abstract: A volatile soldering aid for solder bonding surfaces. A thermally decomposable solid that is suspended in a carrier or dissolved in a solvent is incorporated in a solder assembly having two surfaces separated by a solder preform. The solvent or carrier is subsequently evaporated, and the assembly is heated to decompose the solid and produce a reducing gas. The assembly is then further heated to melt the solder preform. A vacuum may be introduced to remove the gas prior to melting of the solder preform. The solder preform in the assembly may be a monolithic preform or it may be a powder. The solder preform may be provided as a thin film deposited on one or both of the surfaces to be joined. Upon heating, the volatile soldering aid is converted to vapor without forming a liquid phase at the melting point of the solder.

  • Publication number: 20090134017
    Abstract: A system providing selective spin modification and reaction in an electrolytic cell. An electrolytic cell is coupled to a magnet that provides a level-splitting magnetic field in a region of electrolyte adjacent to a working electrode, thus establishing a spin resonance for an unpaired electron associated with a chemical species in the region of electrolyte adjacent to the working electrode. The working electrode carries an excitation current produced by a switching source or amplifier. The excitation current produces an alternating magnetic field adjacent to the working electrode that alters the spin state population density for the unpaired electron associated with a chemical species within the electrolyte, thereby enhancing or inhibiting the reaction of the chemical species during subsequent electrolysis.

  • Publication number: 20090134039
    Abstract: A system providing excitation and selective transport and/or reaction of isotopologues. Two or more isotope effects are combined within a reaction cell to produce transient differentiation of isotopologues through excitation or chemical reaction followed by rapid separation or conversion. A current conductor adjacent to a fluid carries an excitation current produced by a switching source. The excitation current produces an alternating magnetic field adjacent to the conductor that interacts with a population of isotopologues within the adjacent fluid layer to produce a population of reaction intermediates or products that have an isotopic composition different from the initial isotopologues. An electrolytic power supply may also be connected to the conductor to provide a voltage that may be used to selectively attract and electrolyze a portion of the reaction intermediates or products within the adjacent fluid layer.
