摘要： This invention relates to a method of selection of an electrocatalyst array for a desired product outcome. The method comprises exposing an electrocatalyst system to an active agent dissolved or suspended in a conductive solution; and applying a voltage to the electrocatalyst system. The voltage sufficient to cause a multi-electron oxidation or multi-electron reduction of the active species; the electrocatalyst system comprises a counter electrode; and an electrocatalyst array. The array comprising a support substrate; uniformly sized surface structures protruding from a surface of the support substrate; the uniformly sized surface structures have edges and/or apices comprising a catalyst. When the uniformly sized surface structures are of a micrometer scale a first product ratio is produced, when the uniformly sized surface structures are of a nanometer scale a second product ratio is produced, wherein the first and second product ratios are different; the second product ratio requires a higher order electron process compared to producing the first product ratio.

摘要： A battery cell, driven by heat, having a reservoir containing a redox couple electrolyte comprised of paramagnetic and diamagnetic ions. A magnet with a pole, projecting a non-uniform magnetic field unto the electrolyte, the magnetic field having a strong magnetic field area proximal to the magnetic pole and a weak magnetic field area distal to the magnetic pole. A positive electrode is placed in the strong magnetic field area and a negative electrode is placed in the weak magnetic field areas of the electrolyte. Ionic separation occurs as the paramagnetic ions drift to the strong magnetic field area, and the diamagnetic ions are repulsed from the magnetic pole and drift to the weak magnetic field area, causing voltage potential across the positive and negative electrodes. A circuit placed across the positive and negative electrodes of the battery draws electrons from the diamagnetic ions through the negative electrode and the electrical circuit to the positive electrode and into the paramagnetic ions. Paramagnetic ions in the strong field area reduce into converted diamagnetic ions as the paramagnetic ions receive electrons through the positive electrode, the converted diamagnetic ions repelled by the magnetic pole drift to the weak magnetic field area. Additionally, diamagnetic ions proximal to the weak magnetic field area oxidize into converted paramagnetic ions as the diamagnetic ions lose electrons through the negative electrode, the converted paramagnetic ions attracted to the magnetic pole drift to the strong magnetic field area.
