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.

CREB-UPC posted this:Tantalum foams for orthopaedic applications- Easy manufacture. - High degree of porosity (60-80%), high interconnectivity between pores and with a pore diameter greater than 100 µm allowing vascular invasion and bone inward. - With a specially roughened surface topography. - The Young’s modulus (0.5-2%GPa) is very close to that of subchondral bone, enhancing the mechanical biocompatibility. - High surface roughness in conjunction with a low elastic modulus cause fric-tion between the outer surface of the foam and the surrounding bone. 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.

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.

RAMOT at Tel Aviv University Ltd. posted this:Rhenium Nanostructures and ElectrodepositionRhenium (Re) exhibits a unique combination of properties qualifying it to be a high performance engineering material, for applications in aerospace, electronics, medical devices and fuel cells. Rhenium has the second highest melting point of all metals, the third highest Young’s modulus of elasticity and the fourth highest density. While the other refractory metals have a body centered cubic (bcc) structure, Re has a hexagonal close packed (hcp) structure. Consequently, it does not possess a ductile-to-brittle transition and, therefore, can safely be used at subzero temperatures. In addition Re has a creep-rupture strength over a wide high temperature range, up to about 2000°C. These properties imply that structures made of Re have excellent mechanical stability and rigidity, enabling the design of parts with thin sections, extremely attractive for high-temperature structural and high energy system applications. Re nanostructures are likely to exhibit remarkable advantages over other nanostructured metals. Project ID : 3-2012-389
RAMOT at Tel Aviv University Ltd. posted this:Cobalt tungsten phosphorous electroless deposition process and materialsThe new technology of electroless cobalt has lower resistance and enhanced electromigration resistance compared to alternative barriers that are used today. Therefore, for submicron technology, the new technology yields better global interconnect delay, improved reliability and increased resistance to corrosion. Furthermore, it is well conformed to the use since the deposition is a surface reaction which is limited due to the high diffusion of the species material in the liquid phase.

RAMOT at Tel Aviv University Ltd. posted this:Slow positrons for deep defect detectionPositron Annihilation Spectroscopy (PAS) is a unique method of measuring point defects . It is sensitive to defects as small as mono-vacancies (sub-nano scale), in concentration as low as 10-6 appm. Moreover, depending on the apparatus used, it can probe both the surface and bulk regions of the material, allowing depth profiling of defects. A slow positron beam is essentially a collimated, variable, low energy, positron source for PAS measurements. The collimation of the beam and energy control allows for non distractive studding of different layers of the material . A typical slow positron beam is composed of three main components: (1) Positron source, (2) positron moderator, (3) positron transport beam line. Positrons are emitted from the source isotropically with a wide energy distribution, with a typical mean of 200 keV (for 22Na). In order to produce a mono-energetic beam, they are passed through a moderator, in which they lose most of their initial energy (up to few eV). Then they are shaped into a beam and accelerated using electro-magnetic fields to the sample. By varying the fields, one can control the positron energy. Project ID : 11-2012-316
