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 Alicante posted this:Solar energy use for water potabilization by electrodialysisA Spanish research group owns the know-how for the desalination of saline water for human consumption or irrigation by means of systems of electrodialysis powered by photovoltaic solar energy. The main advantages are that it is non-polluting and has a low maintenance cost. The technology is fully developed and useful for organisations dealing with water supply problems. A partner to set up the electrodialysis-photovoltaic system in its facilities and/or carry out feasibility studies is sought. Innovative aspects: The desalination system makes use of renewable energy, so it is respectful with the environment and not contributing to the climatic change. Desalination system for remote areas with access to saline reservoirs, where the supply of electricity is particularly expensive or even non-existent, or for coastal zones where there are saline aquifers and the hydric resources are scarce.

The invention DARWIN-PCM consists of a dynamic thermal system to be used in buildings to minimize their energy consumption for space heating and cooling. The invention can be implemented in any sort of building envelope including walls, floors, roofs, fenestrations, and doors. It is composed of several layers of materials, one of them is mobile and contains a material with capacity to absorb and release high amount of heat - such as phase- change materials (PCM).
Universitat de Lleida posted this:Advanced organic compounds with enhanced thermal energy storage capacityProduction of ionic liquids, bisimidazolium salts obtained from glycerol and carboxylic acids, which show a high thermal energy storage (TES) capacity. Multi-application technology based on new phase change materials (PCM) with higher thermal properties than those used nowadays. These compounds are bisimidazolium salts, which may be obtained from affordable natural sources - fats and oils, usually by-products at the agro-food industry - through a patented procedure.
