  • Patent number: 8598018
    Abstract: The present invention provides a method of forming an electrode having reduced corrosion and water decomposition on a surface thereof. A conductive layer is deposited on a substrate. The conductive layer is partially oxidized by an oxygen plasma process to convert a portion thereof to an oxide layer thereby forming the electrode. The oxide layer is free of surface defects and the thickness of the oxide layer is from about 0.09 nm to about 10 nm and ranges therebetween, controllable with 0.2 nm precision.

  • Publication number: 20110308969
    Abstract: The present invention provides a method of reducing corrosion and water decomposition on a surface of an electrode having a titanium nitride conductive layer disposed on a substrate and estimating extent of reduction thereof. The electrode is immersed into a solution containing a hydroxyl-functional compound. Thereafter, a voltage is applied to the titanium nitride conductive layer of the electrode. The extent of oxidation of the titanium nitride conductive layer is correlated with the extent of formation of oxide of titanium nitride and/or the extent of oxidation of the titanium nitride conductive layer is correlated with the increase of surface roughness. The extent of water decomposition is correlated with formation of hydrogen and oxygen bubbles.

  • Publication number: 20110308949
    Abstract: The present invention provides a nano-fluidic field effective device. The device includes a channel having a first side and a second side, a first set of electrodes adjacent to the first side, a second set of electrodes adjacent to the second side, a control unit for applying electric potentials to the electrodes and a fluid within the channel containing a charge molecule. The first set of electrodes is disposed such that application of electric potentials produces a spatially varying electric field that confines a charged molecule within a predetermined area of said channel. The second set of electrodes is disposed such that application of electric potentials relative to the electric potentials applied to the first set of electrodes creates an electric field that confines the charged molecule to an area away from the second side of the channel.
