20110127170 | Cobalt Oxyfluoride Catalysts For Electrolytic Dissociation Of Water - Disclosed are electrolysis catalysts formed from cobalt, oxygen and fluorine. They can be formed as a coating on an anode by conducting an electrolysis reaction using an electrolyte containing cobalt and fluoride. The catalysts will facilitate the conversion of water to hydrogen gas and oxygen gas, even at pH neutral/room temperature reaction conditions. The resulting hydrogen gas is a means of storing renewable energy for use in hydrogen powered vehicles or the like. | 06-02-2011 |

20120305408 | Buffered Cobalt Oxide Catalysts - Disclosed are electrolysis catalysts formed from cobalt, oxygen and buffering electrolytes (e.g. fluoride). They can be formed as a coating on an anode by conducting an electrolysis reaction using an electrolyte containing cobalt and an anionic buffering electrolyte. The catalysts will facilitate the conversion of water to oxygen and hydrogen gas at a range of mildly acidic conditions. Alternatively, these anodes can be used with cathodes that facilitate other desirable reactions such as converting carbon dioxide to methanol. | 12-06-2012 |
20130004453 | NYLON-3 CO-POLYMERS AND SYNTHETIC LUNG SURFACTANT COMPOSITIONS CONTAINING SAME - Non-natural oligomers have recently shown promise as functional analogues of lung surfactant proteins Band C (SP-B and SP-C), two helical and amphiphilic proteins that are clitical for normal respiration. The generation of non-natural mimics of SP-B and SP-C has previously been restlicted to step-by-step, sequence-specific synthesis, which results in discrete oligomers that are intended to manifest specific structural attributes. Presented herein an alternative approach to SP-R mimicry that is based on sequence-random copolymers containing cationic and lipophilic subunits. These materials, members of the nylon-3 family, arc prepared by ling-opening polymelization of 13-lactams. The best of the nylon-3 polymers display promising in vitro surfactant activities in a mixed lipid film. Pulsating bubble surfactometry data indicate that films containing the most surface-active polymers attain adsorptive and dynamic-cycling properties that surpass those of discrete peptides intended to mimic SP-B. | 01-03-2013 |
20130206608 | Catalysts Having Mixed Metal Oxides - Disclosed are methods for generating oxygen via an electrolysis reaction. One places an anode and a cathode in aqueous solution, and uses an external source of electricity to drive the electrolysis reaction from the anode and cathode. The anode has at least three metal oxides, preferably with nickel oxide or cobalt oxide as at least one of the oxides. Also disclosed are electrodes designed for catalyzing oxygen consumption or formation reactions, where the electrodes have a mix of such three metal oxides. | 08-15-2013 |
