Universidad de Alicante posted this:New family of dyesThe main innovative aspects of this technology regarding current methods of synthesis are: • The indolizine dyes are obtained in one step from commercially available materials, unlike current procedures, which involve multiple steps. This is an advantage in the production process, as it reduces costs, increases the final yield and less waste is generated. • The procedure is based on a very simple treatment which produces indolizine dyes in yields higher than 70%. • The present invention does not require the use of inert atmosphere, dry solvents or physical activation (heat or radiation) to obtain the final product. • Unlike other methodologies for preparing indolizine dyes (requiring temperatures around 100°C), this process is carried out at room temperature and atmospheric pressure, which simplifies the method and decreases production costs. • This is an environmentally friendly technology because it does not use solvents such as dioxane, pyridine, chloroform or benzene, which are used in other methods and are characterized by their high toxicity and demonstrated carcinogenicity. • The selectivity of the reaction is very high. The indolizine dye is obtained with absolute control, obtaining a single isomer of the ten possible.

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.
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.

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
