Centre Technology Transfer CITTRU posted this:Method of isolation and purification of xanthophylls from diatom cultureXanthophylls, with their antioxidant, anticancer, anti-inflammatory and neuroprotective properties, found important applications in food and nutrition, cosmetic and environmental industries, as well as pharmacy and medicine. Diadinoxanthin (Ddx) and diatoxanthin (Dtx) are two pigments that belong to xanthophylls family. The availability of Ddx and Dtx on the market is low and up to date limited as they are sold exclusively in small quantities at extremely high prices to be used as HPLC calibration standards. The solution of the above mentioned problems is the 5-step method for the isolation and purification of Ddx and Dtx developed at the Jagiellonian University..
UNIVERSIDAD DE ALICANTE posted this:Innovative procedure for the preparation of silica fillings without shrinkageThe research group Carbon Materials and Environment of the University of Alicante has developed a procedure to prepare silica fillings preventing their shrinkage by the deposition of a thin film prior to the synthesis of the filling. Modifying the said thin film, the filling properties are modified, obtaining highly satisfactory results in the case of the mesoporous thin films in all case studies. This method also allows obtaining silica fillings with different diameters and their incorporation into different types of supports such as glass, steel or honeycombing cordierite monoliths. Following this procedure the shrinkage of the fillings is avoided, which is a common occurrence with the established preparation protocols.
Fundació URV posted this:NEW PROCEDURE FOR OBTAINING MONOLAYERS OF FUNCTIONALIZED NANOPARTICLESThis new procedure (not described in the bibliography) allows the manufacture of monolayers of metal nanoparticles linked by molecules of organic compounds. As you can see in Specifications, this procedure consists in two successive processes. One of the main advantages of this technology is the minimization of impurities in the functionalized monolayer compared to commonly used techniques. Besides, the manufacture of Schotty diode with this new procedure has been shown for the first time. In the same line, this procedure allows the use of monolayers of metal nanoparticles for metabolite detection. These are two unique and differents aspects of this technology in relation to other known used techniques.

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.

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.
