Universidad de Alcalá-OTRI posted this:Portable device to measure the displacement maps on surfaces in the three spatial directionsA Spanish research group from the Department of Signal Theory and Communications of the University of Alcalá along with a Spanish research group from the Department of Mechanical and Mining Engineering of the University of Jaén has developed a portable optoelectronic device to measure the displacement of each surface element in an object when is subjected to deformation. In particular, the device allows obtaining maps of long range displacement (greater than mm) in dynamic regime (in real time). Thus this system is very useful in the experimental study of the materials’ mechanical properties, especially if they suffer large deformations at high speed. It is a computationally simpler alternative and more inexpensive than the digital mapping technique for 3D images which is currently the only one allowing such measures. The group seeks licensing agreements, collaborative and commercial agreements with technical assistance.
Universidad de Alicante posted this:Noble metal-free ceria-based diesel soot combustion catalyst, suitable for gas purification in Diesel engine exhaustsThe developed catalyst does not use Pt, which leads to a cheaper product. The resulting catalyst shows equal or even better performance as Pt catalysts. Following the patented procedure of synthesis, the catalyst produced has a lower particle size. This leads to higher surface per particle and therefore, a better ratio yield when interacting in oxidation reactions, leading to a higher oxygen production rate.

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.
Centre Technology Transfer CITTRU posted this:Catalysts for low-temperature combustion of methane from low-caloric sources and methods for their preparationDue to the rising emission of methane and its extensive contribution to the greenhouse effect, the reduction of CH4 emissions from low-caloric anthropogenic sources is currently a vital importance. The main sources of the methane emission are: exploitation of oil pools, coal mining, pas power stations, landfills, agriculture and biomass. The most popular method of the reduction of methane is its catalytic combustion. Unfortunately, this method has few limitations associated mainly with hard activation of the C-H bond in CH4 and low concentrations of methane in the emitted gases. The catalytic oxidation of methane is limited also by the very large airflows (of order 105 m3/min), passing through the catalyst bed during the process. There is still a lack on the market of a technological solution based on total catalytic combustion of CH4 in the economically reasonable low-temperature window, i.e. below 400 °C. The most popular method among the methods limiting the emission of methane to the atmosphere is the one based on its catalytic combustion. However, this procedure has disadvantages, mainly due to the high activation energy of methane molecules and also because of the low concentration of methane emitted from anthropogenic sources. There is no technology allowing effectively combusting of methane with the concentration of 1-2 % and in the economically justified temperatures, i.e. lower than 400 °C. The fundamental advantages of offered solutions are: - method for preparing catalysts that ensures the repeatability of the parameters and high efficiency in the reactions of methane combustion, - increased both the activity and the thermal stability of the catalysts in comparison with other systems described in the literature, - possibility of using the catalysts in the total oxidation of methane emitted from the low-caloric sources at temperatures below 400 °C.
Universidad de Alicante posted this:New process for the stereoselective synthesis of acetylenic compounds used as additives in galvanic bathsRegarding the existing state of the technique, the electrochemical processes have characteristics which make them very adequate to be applied for the synthesis of organic compounds with industrial application. Here, oxidation processes occurs upon electrodes named anodes where the substance which must be oxidized loses its electrons on the anode without needing conventional oxidising agents. Therefore, contaminants derived from the use of conventional oxidising agents are not generated and hence, no need for the management of hazardous residues is applicable. On the other hand, the electrochemical processes are developed under soft conditions (atmospheric pressure and room temperature) and clearly facilitate further processes of separation of one of the compounds of the reaction mixture.

Universidad de Alicante posted this:Energy absorbing device in motor vehicle collisionsResearchers at the University of Alicante have devised a system to partially absorb the energy generated in a crash involving at least one motor vehicle traveling at a high or medium speed. 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
