    Abstract: Novel coatings are disclosed prepared from electropolymerization of electropolymerizable monomers-analyte complexes onto a conducting layer or non-conducting of a substrate, where the analyte is removed by electrochemically mediated washing permitting linear molecular sensing of the analyte over a wide concentration range. The coating may also include templating particles deposited on the electrode substrate prior to electropolymerization, where the particles can be removed to form a submicron structured coating. Methods for making and using the coatings are also disclosed.

  • Patent number: 8268156
    Abstract: Processes are provided herein for the fabrication of MEMS utilizing both a primary metal that is integrated into the final MEMS structure and two or more sacrificial secondary metals that provide structural support for the primary metal component during machining. A first secondary metal is thinly plated around the primary metal and over the entire surface of the substrate without using photolithography. A second secondary metal, is then thickly plated over the deposited first secondary metal without using photolithography. Additionally, techniques are disclosed to increase the deposition rate of the first secondary metal between primary metal features in order to prevent voiding and thus enhance structural support of the primary metal during machining.

  • Publication number: 20120114861
    Abstract: Electrochemical fabrication methods for forming single and multilayer mesoscale and microscale structures include the use of diamond machining (e.g. fly cutting or turning) to planarize layers. Some embodiments focus on systems of sacrificial and structural materials which can be diamond machined with minimal tool wear (e.g. Ni—P and Cu, Au and Cu, Cu and Sn, Au and Cu, Au and Sn, and Au and Sn—Pb). Some embodiments provide for reducing tool wear when using difficult-to-machine materials by (1) depositing difficult to machine materials selectively and potentially with little excess plating thickness and/or (2) pre-machining depositions to within a small increment of desired surface level (e.g. using lapping) and then using diamond fly cutting to complete the process, and/or (3) forming structures or portions of structures from thin walled regions of hard-to-machine material as opposed to wide solid regions of structural material.

  • Publication number: 20120082857
    Abstract: The invention relates to a method for forming a protective coating against high-temperature oxidation on a surface of a refractory composite material based on silicon and niobium, wherein chromium present on the surface to be protected is reacted with a reactive gas which contains silicon and oxygen in order to produce a composite coating having two phases, a first phase of which is an oxide phase based on silica which has viscoplastic properties and a second phase of which is based on silicon, chromium and oxygen, and wherein the first phase and second phase are coalesced at high temperature, which allows a protective coating to be formed in which the second phase acts as a reservoir to reform, during operation, the first phase by means of reaction with an oxidising gas. The invention is preferably used in the field of aeronautical engines.
