Universidad de Cádiz posted this:New nanostructured catalyzers without noble metals and with low content in lanthanidesSince the 1990's, the mixed oxides of cerium and zirconium have replaced cerium oxide in the composition of the three-way catalyzers used in the automotive industry. The fundamental reason for this is the improved textural behaviour of the oxides of Ce/Zr, compared with the effectiveness of cerium oxide. These mixed oxides are also more effective in the exchange of oxygen with the medium. The Oxygen Storage Capacity (OSC) of the compound is therefore the key property for its application as a component in catalyzers. However, the rare earth metals which are the critical component of these catalyzers have currently increased considerably in price, due to greater demand and limited supply from the few exporting countries. The research group working in this field has been able to obtain nanostructured oxides of Ce/Zr and Ce/Zr/Y with low content in Ce that present very good oxygen storage properties. In addition, costly noble metals are not employed in their formulation, which represents an important economic advantage.

Furthermore, the sintered ceramic substrate guarantees superior adhesion and resistance to fracture under high mechanical loads. The fabricated temperature sensitive diamond surface comprises well adhered ohmic contacts deposited on the backside of the dielectric ceramic substrate. This configuration prevents interaction between the temperature sensitive surface and the surrounding environment which is essential for biochemical devices applications. Furthermore, the planar geometry of the disclosed thermistor maximizes the contact region between the temperature sensitive surface and any solid flat surface on which it is placed. In this way, improved response times are obtained comparing to traditional round shaped thermistors.

It is a passive protection system for vehicles which absorbs the maximum amount of mechanical energy in a crash with minimal added weight and volume. Assumes additional protection that enhances the vehicle's passive safety, minimizing the consequences of a collision for the passengers. The system has an innovative design that allows placing it in different positions inside the vehicle or making structural parts and is manufactured with advanced materials. Innovative aspects The system is designed to provide protection that goes beyond the current regulations for passenger cars, as it is able to absorb a larger proportion of the mechanical energy generated in a collision. Also improve the passive safety of vehicles (vans, trucks) or special vehicles (ambulances, fire trucks, armored vehicles) in circulation. It also provides substantial improvements for heavy duty vehicles, contrary to what is happening now should be able to absorb themselves much of the energy produced in a collision with a vehicle lighter, thereby minimizing the potential damage that may occur in people who travel light vehicle. The system consists in several stages which act consecutively on impact, absorbing energy in a gradual and proportional to the energy generated in the collision, which is a lower acceleration on passengers, thereby reducing the potential injuries. Less weight, volume and system size compared to traditional structural systems, through the use of advanced materials: tensile filaments that act in case of collision, thermosets broken links which act by absorbing the impact energy generated in the fiber and combined with high strength composite metal / polymer composite micro / nanostructures

RAMOT at Tel Aviv University Ltd. posted this:Effective cooling of ICs with microchannel heatsinkA miniature heat sink containing microchannels for extremely effective forced air cooling of high power electronic devices. Multiple vortex rings are generated and propagate along the channels. This causes optimum mixing of the air which leads to enhanced heat removal from the hot device. Due to the small size of the microchannel, a large number of such channels can be placed over a given heat generating surface in a single layer or multiple layers (the thickness of a layer is less than 1mm) to yield a very high heat removal rate within a very small size heat sink. The channels can also be integrated as separate layers in a 3-D electronic circuit architectures, located between layers of heat generating components to effectively remove heat and resolve hot-spot regions.

RAMOT at Tel Aviv University Ltd. posted this:autonomous pressure relieving aids for wheelchair patientsThe present invention provide a seat cushion for an individual suffering from loss of sensation in the buttocks but having sensation in higher regions of the trunk. The cushion may be used, for example, in individuals who have undergone spinal cord injury (SCI). The cushion of the invention provides tactile stimulation to regions of the surface of the individual’s body where the individual has retained tactile sensitivity (e.g. above the SCI level) to induce the individual to shift his sitting position. The cushion thus provides tactile sensory compensation, by transferring the sense of weight-bearing pressures from an insensitive body site which bears bodyweight loads (e.g. a body site affected by a neural injury) to a different, sensitive site which is not necessarily weight-bearing at the time. By repetitively shifting the location of the tactile stimulation, the cushion promotes frequent changes in posture, which tend to reduce the risk of pressure ulcers. Project ID : 8-2011-265

State of the art rotational rheometers use fixed and rigid blades, which rotate against a fluid and have limited accuracy at extremely high or low viscosities. Our inventions replaces the rigid blades with flexible blades work by utilizing fluid mechanics and fluid-blade interaction principles and allow to detect small changes of viscosity. The very small viscosity changes are amplified through the interaction of the thin boundary layers on the sidewalls, the high shear in the small gap between the wall and the blade and on the rotating flexible blade itself.

It converts a vehicle engine into an air pump during decelerations. It harvests the braking energy and stores it as compressed air for subsequent use to restart the engine in stop/start operation, saving battery and starter motor life. It also saves fuel as the compressed air also assists the normal engine-driven air compressor. Furthermore it can enhance the turbo thus reducing black smoke during acceleration from stationary
