University of Vigo posted this:New non-destructive method for “in situ” monitoring of anticorrosive protection of organic coatingsThe main novelty of the device and procedure is the new portable sensor adaptable to virtually any surface. The device, fixable by vacuum to the surface under study, makes possible the measurement of the electrochemical interfacial impedance, that is the main parameter of interest for adherence quality and anti-corrosion performance.
University of Vigo posted this:A novel mild and efficient method to prepare ε-Caprolactam precursor of Nylon 6ε-Caprolactam, the main precursor of the synthetic fibber Nylon 6, is prepared from cyclohexanone oxime by treatment with a new salt as promoter. This procedure requires mild reaction conditions and affords excellent levels of conversion and selectivity to obtain pure ε-caprolactam. No reaction by-products are formed. The new promoter salt is cheap, no corrosive, and easy to prepare. All these characteristics makes the procedure suitable for undustrial purposes.
Fundació URV posted this:Environmentally friendly processing of thermosets by two-stage sequential aza-Michael addition and free-radical polymerization of amine-acrylate mixturesEnvironmentally friendly preparation of thermosets for applications on thermosensitive substrates. A two-step curing process, which consists in an Aza-Michael addition at room temperature, followed by UV radical polymerization of acrylates or methacrylates amine formulations without the need of adding solvents. The presence of amines in the structure suppress the radical inhibition by oxygen, which is a typical drawback in radical polymerizations. The invention allows leading the curing in two separate stages with a stable intermediate material, being the process controlled by the amount of amine in the formulation.
DIT Hothouse posted this:iSeal: Advanced Surface Treatment for Protection against TribocorrosionThis invention is based on the application of a hybrid organic/inorganic treatment onto an exposed surface – either as a stand-alone treatment or as a sealant. The treatment is applied using an electrochemical deposition technique, allowing for the development of conformal coatings, irrespective of design complexity. Layer thicknesses are low (10-100nm) but resistance in corrosive marine environments indicate corrosion rates comparable to technologies currently employed by the aerospace and automotive industries. Corrosion rates are reduced by between 103 and 105 times, dependant on the nature of the porous coating. Tests on metallic coatings indicated a reduction in corrosion rates of approximately 103-104 while tests on ceramic coatings indicated a reduction in corrosion rates of approximately 105. By applying the hybrid treatment as a sealant treatment onto a porous wear resistant coating, concerns regarding the effect of mechanical damage are dramatically reduced. In addition, surface roughness levels are similar to electropolished finishes.

It is ap-proximately 1.5 times greater than the friction produced by conventional mesh systems or with titanium or cobalt-chromium spherules, achieving an excel-lent primary stability of the implant.
RAMOT at Tel Aviv University Ltd. posted this:Electroless Deposition of Thin Copper-Molybdenum Layers for ULSI ApplicationsElectroless deposition of thin copper-molybdenum layers is a method of producing highly reliable nano-wires for interconnect applications to solve the problems in the use of copper interconnects. By adding small amount of molybdenum the copper resistance to electromigration is increased. This reduces corrosion and prevents contamination of the silicon substrate. This innovation is of major importance to the manufacturers of ultra large-scale integration (ULSI) applications. Copper is a preferred material and is lower in cost, hence this innovation can significantly impact on both profit margins and performance in the ULSI industry. Project ID : 11-2007-121
RAMOT at Tel Aviv University Ltd. posted this:High Current Superconducting leadsA buffer layer of Yttrium stabilized Zirconia is introduced which allows the growth of high fidelity thick (> 1 micron) layers of superconducting YBCO on sapphire substrates. The high buffer quality is achieved by sputtering the material from a YSZ target unto the sapphire substrate held at a temperature higher than the growth temperature of the HTS films to be deposited subsequently, above 900C. From these thick layers, superconducting leads are prepared which are suitable for use in supercooled magnets such as in MRI machines and Maglev generators. Project ID : 11-2011-243

RAMOT at Tel Aviv University Ltd. posted this:Super Organic Tunable and White-Light Emitting Diode (OLED) by a Natural Chromophore Separation MatrixA bio-organic framework of mucin, controlling electronic interactions between two or more energetically interacting materials, is presented. The hydrophilic mucins act as a host material for introduced nano-sized hydrophobic dyes. These can be combined in any proportion to generate photo-luminescent emitters fully tunable to any visible wavelength. The technology can provide a process for efficient and low-cost production of coatings with photo-luminescent properties. Mucins are derived from a variety of bio sources, such as bovines or ovines. We have developed a proprietary method for extracting mucins from jellyfish and are able to fabricate a homogenous photo-luminescent coating capable of controlling the emitted wavelength to any RGB combination.
