Universidad de Alcalá-OTRI posted this:Acoustic propagation model and location systems for underwater environmentsGEINTRA, a research group from the Department of Electronics of the University of Alcalá, provides a model for studying the acoustic propagation in underwater environments. This model is useful for communications and positioning systems. The proposed model provides the channel response for the usual environmental phenomena. The model simulate how these phenomena affect a particular acoustic signal, and therefore, the performance of an underwater system based on acoustic signals can be evaluated previously to its deployment. The model has been tested for the case of underwater localization systems. GEINTRA is looking for companies working in telecommunications and IT sectors or performing works related to exact science and physics to achieve technical cooperation agreements.

Universidad de Alcalá-OTRI posted this:Semi-automated portable capillary electrophoresis instrument .A research group from the Department of Analytical Chemistry, Physical Chemistry and Chemical Engineering at the University of Alcalá has developed a new portable capillary electrophoresis system (P-CE). The P-CE has a battery system which gives it electrical autonomy. It is designed inside a 35x15x45 cm suitcase. It is a capillary electrophoresis assisted by external pressure. Electrical consumption is not required to generate the pressure, which increases the instrument autonomy. The group is looking for companies working in medical or biological sector or companies which make food, water or forensic analysis to reach licensing agreements, partnerships and commercial agreements with technical assistance.

UNIVERSIDAD DE ALICANTE posted this:Black titanias for photocatalysis, solar cells and environmental applications• The titania is black, and then absorb in the whole visible range (band gap 2.74 eV) and maintains its photocatalytic activity at least after 5 cycles reaction with an efficiency of 95 %. • The synthesis process is simple, inexpensive and versatile (a wide variety of functional compounds can be incorporated in the structure of the titania lattice avoiding blocking the mesoporosity and maintaining the anatase structure). • Excellent thermal and hydrothermal stability. The functionality is incorporated into the structure of the titania being protected thereby.
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.
Universidad de Cádiz posted this:The complete elimination of oily wasted using supercritical water oxidationThe technique exploits the extreme oxidation characteristics of supercritical water, (defined as 221 bar and 374 ºC). Under these conditions oils become soluble, and a single homogeneous reaction phase is obtained in which the organic compounds and oxygen are brought into contact. This results in an almost instantaneous break down of organic substances into harmless products, essentially water and CO2 (without the formation of NOx, SOx, CO or other products of incomplete oxidation). The University of Cadiz, a leading center of research for ecological waste treatment, recently conducted a comprehensive study of the hydrothermal treatment of a wide variety of compounds representing the principal effluents generated by industrial machining (classified as dangerous waste under current regulations). The research found the design achieved greater than 99% elimination of the contamination in only a few seconds. On the basis of these results, we consider the system to represent a significant breakthrough in the elimination of dangerous wastes, offering a commercially viable, ecological alternative to simply storing up toxic waste in tanks or ponds.
