| 20150090601 | CATHODIZED GOLD NANOPARTICLE GRAPHITE PENCIL ELECTRODE AND METHOD FOR GLUCOSE DETECTION - The cathodized gold nanoparticle graphite pencil electrode is a sensitive enzymeless electrochemical glucose sensor based on the cathodization of AuNP-GPE. Cyclic voltammetry shows that advantageously, the cathodized AuNP-GPE is able to oxidize glucose partially at low potential (around −0.27 V). Fructose and sucrose cannot be oxidized at <0.1 V, thus the glucose oxidation peak at around −0.27 V is suitable enough for selective detection of glucose in the presence of fructose and sucrose. However, the glucose oxidation peak current at around −0.27 V is much lower which should be enhanced to obtain low detection limit. The AuNP-GPE cathodization increases the oxidation peak current of glucose at around −0.27 V. The dynamic range of the sensor is in the range between 0.05 to 5.0 mM of glucose with good linearity (R | 04-02-2015 |

| 20090166211 | Solid Electrolytic Capacitor Containing a Conductive Polymer - A method for forming an electrolytic capacitor is disclosed. The method includes forming a conductive polymer coating over the dielectric layer by polymerizing a monomer in the presence of an oxidative polymerization catalyst. The conductive polymer coating is formed by dipping the anode in a polymerization solution comprising the monomer, the oxidative polymerization catalyst, and a polar solvent. The polymerization solution has a temperature of less than about 20° C. Cooling the polymerization solution further stabilizes the polymerization solution and prevents premature polymerization of the monomer(s). Thus, the resulting conductive polymer layer can be more intimately positioned with respect to the anode. As a result, the formed capacitor can exhibit better performance. | 07-02-2009 |

| 20110266157 | Wear resistant wheel coating and method - This invention teaches a method of coating a vehicle wheel to increase wear resistance which, in its preferred embodiment, includes the steps of providing a vehicle wheel and applying a wear resistant coating between/intermediate a primer and a topcoat. The wear resistant coating is applied to at least the tire bead flange of the vehicle wheel but may be applied to any area of the wheel. It is advantageously comprised of a MIL-P-53022B Type II lead and chromate free, corrosion inhibiting epoxy primer with an addition of 3% polytetrafluoroethylene (PTFE), and is formulated in such a manner so as to allow “wet on wet” application over a cured MIL-P-53084 primer. This application method improves adhesion through surface to surface covalent reaction between the polymerization of polyurethane top coat and the polymerization of intermediate epoxy polyamide wear resistant coating. The wear resistant coating is of particular use with vehicle wheels made from cast or forged aluminum, but may also be used by itself over steel wheels that have been pretreated to TT-C-490. It may also be used over anodized, electrocoated, or DOD-P-15328 wash primed aluminum as a standalone non CARC wear resistant coating. | 11-03-2011 |
