Abstract:
Localized excess protons are created with an open-circuit water electrolysis process using a pair of anode and cathode electrodes for a special excess proton production and proton-utilization system to treat a substrate material plate/film by forming and using an excess protons-substrate-hydroxyl anions capacitor-like system. The technology enables protonation and/or proton-driven oxidation of plate/film and/or membrane materials in a pure water environment. The present invention does not require the use of any conventional acid chemicals including nitric and sulfuric acids for the said industrial applications. The application of localized excess protons provides a special energy recycling and renewing technology function to extract latent heat including molecular thermal motion energy at ambient temperature for generating local proton motive force (equivalent to Gibbs free energy) to do useful work such as driving ATP synthesis and proton-driven oxidation of certain substrate metal atoms.
Abstract:
Disclosed are a polishing slurry used in a polishing process of tungsten and a method of polishing using the same. The slurry includes an abrasive for performing polishing and an oxidation promoting agent for promoting the formation of an oxide. The abrasive includes titanium oxide particles.
Abstract:
A touch screen sensor includes a visible light transparent substrate and an electrically conductive micropattern disposed on or in the visible light transparent substrate. The micropattern includes a first region micropattern within a touch sensing area and a second region micropattern. The first region micropattern has a first sheet resistance value in a first direction, is visible light transparent, and has at least 90% open area. The second region micropattern has a second sheet resistance value in the first direction. The first sheet resistance value is different from the second sheet resistance value.
Abstract:
Nanostructures and microstructures are formed by patterning methods such as Dip Pen Nanolithography (DPN) or microcontact printing of organic molecules functioning as a resist on a substrate followed by an etching step. The etch resist is a patterning composition and can contain on a substrate including polyethylene glycol (PEG). Positive and negative etch methods can be used.
Abstract:
A method of patterning a deposit metal on a polymeric substrate is described. The method includes providing a polymeric film substrate having a major surface with a relief pattern having a recessed region and an adjacent raised region, depositing a first material onto the major surface of the polymeric film substrate to form a coated polymeric film substrate, forming a layer of a functionalizing material selectively onto the raised region of the coated polymeric film substrate to form a functionalized raised region and an unfunctionalized recessed region, and depositing electrolessly a deposit metal selectively on the unfunctionalized recessed region.
