Abstract:
Methods for the low-temperature synthesis of an integrated, corrosion-resistant coating structure for metal substrates by means of multi-component pack cementation are provided. The synthesis of the integrated coating structures at low temperatures can avoid or minimize degradation of the mechanical properties of the substrates. The integrated coating structures can increase the lifetime of high temperature steels under severe steam environments and, therefore, provide a technological enabler for the high-temperature operation of steam power generation plants.

Methods for depositing ruthenium can include positioning a substrate in a processing chamber, the substrate having a barrier layer formed thereon, heating and maintaining the substrate at a first temperature, flowing a first deposition gas into a processing chamber, the first deposition gas comprising a ruthenium containing precursor, generating a plasma from the first deposition gas to deposit a first ruthenium layer over the barrier layer, flowing a second deposition gas into the processing chamber to deposit a second ruthenium layer over the first ruthenium layer, the second deposition gas comprising a ruthenium containing precursor, depositing a copper seed layer over the second ruthenium layer and annealing the substrate at a second temperature.
Abstract:
Networks of single-walled carbon nanotubes (SWCNTs) decorated with Au-coated Pd (Au/Pd) nanocubes are employed as electrochemical biosensors that exhibit excellent sensitivity (2.6 mA mM−1 cm−2) and a low estimated detection limit (2.3 nM) at a signal-to-noise ratio of 3 (S/N=3) in the amperometric sensing of hydrogen peroxide. Biofunctionalization of the Au/Pd nanocube-SWCNT biosensor is demonstrated with the selective immobilization of fluorescently labeled streptavidin on the nanocube surfaces via thiol linking. Similarly, glucose oxidase (GOx) is linked to the surface of the nanocubes for amperometric glucose sensing. The exhibited glucose detection limit of 1.3_M (S/N=3) and linear range spanning from 10 μM to 50 mM substantially surpass other CNT-based biosensors. These results, combined with the structure's compatibility with a wide range of biofunctionalization procedures, would make the nanocube-SWCNT biosensor exceptionally useful for glucose detection in diabetic patients and well suited for a wide range of amperometric detection schemes for biomarkers.

Provided is a rolled copper foil or electrolytic copper foil for an electronic circuit to be used for forming a circuit by etching, wherein the copper foil comprises a nickel or nickel alloy layer with a lower etching rate than copper formed on an etching side of the rolled copper foil or electrolytic copper foil, and a heat resistance layer composed of zinc or zinc alloy or its oxide formed on the nickel or nickel alloy layer. This invention aims to prevent sagging caused by the etching, to form a uniform circuit having the intended circuit width, and to shorten the time of forming a circuit by etching as much as possible, when forming a circuit by etching a copper foil of the copper-clad laminate; and also aims to make the thickness of the nickel or nickel alloy layer as thin as possible, to inhibit oxidation when exposed to heat, to prevent tarnish (discoloration) known as “YAKE”, to improve the etching properties in pattern etching, and to prevent the occurrence of short circuits and defects in the circuit width.
