UNIVERSIDAD DE ALICANTE posted this:Novel method to fabricate highly selective sensors for different substances of interestThe research group "Electro catalysis and Electrochemistry of Polymers", Department of Physical Chemistry at the University of Alicante has developed a novel method that allows highly selective electrode manufacture biometrics to detect any biochemical substance of interest, food or environmental. The method is based on the electro assisted deposit of molecularly imprinted silica layers on different electrodes. This allows a fast and efficient detection of the molecule of interest, independently of the other interfering. In addition, allows the regeneration of the electrode in a very simple way and lets its usage almost indefinitely. Innovative aspects The biometrical electrode manufacturing method is based on a electro assisted method of molecularly imprinted silica layers on different electrodes. With this new procedure, we obtain uniform and consistent layers of silica that allow highly selective detection of any biochemical substance of interest, food or environmental when these electrodes are used as amperometric, voltammetric, impedimetric and potentiometric sensors. Main advantatges of the technology The main advantage of the electro assisted deposit respect to conventional methods of thin film deposition (spin-coating or dip-coating), lies in the control of consistency and porosity of the layers. Due to the prevention of uncontrolled pore formation, avoids the indiscriminate passage of species from the solution to the electrode surface, reducing the interference in the detection of the analyte of interest. It has a high specificity and affinity for the molecule of interest. High control on the deposition of silica when is done by electro assisted mode. The possibility of varying the thickness of the silica layer and layer morphology allows for a highly consistent and reproducible layer. Electro assisted deposit method is capable of "self-healing", i.e. prevents the formation of holes in the assisted layer that interfere with the detection of the molecule of interest. With continued use, the sensor loses its effectiveness by the collapse of the pores with the species to be determined. In this case, the regeneration process is very simple: just repeat the procedure for removing the template molecule to be performed after the gel layer (electrochemical extraction or cleaning solvents). Thus, the pores of the sensing phase are released for use again.

Thanks to this system can perform reliable measurements in any part of the structure without requiring the use of attached external sensors. Innovative aspects The technology of the University improves the existing technologies due to the use of carbon nanofibers that provide an easier to disperse homogeneously in the cement matrix without additives or additional steps in the manufacturing process. The technology also increases the contact area matrix-nanofiber. This gives to the material more sensitive to the stress of the structure and allows more reliable measurements.

RAMOT at Tel Aviv University Ltd. posted this:Delayed Dictionary CompressionData compression is a preferred solution, since there is no need to dig in the ground for many kilometers in order to build new high bandwidth links. The Delayed Dictionary Compression (DDC) family of algorithms was invented by Prof. Yossi Matias and Mr. Raanan Refua. The motivation was to release the bottleneck of low level infrastructures - data transfer links. Current data compression techniques for packet networks allow a good compression and a poor latency, or poor compression ratio and a good latency. Project ID : 4-2012-319

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
