Universitat Politècnica de Catalunya - UPC posted this:New strategy for local diffusion of dopants in crystalline siliconA new methodology to replace conventional diffusion processes has been developed and patented. This simple procedure offers a wide versatility, since it allows the creation of locally doped regions without photolithography steps while simultaneously reducing the global thermal budget of the emitter creation process. The potential of the method has been already confirmed for silicon solar cell applications. Partners to further develop the technology and/or to establish commercial agreements along with technical cooperation are sought.
Universidad de Alicante posted this:Stand-alone system for the purification of brackish water directly powered by photovoltaic solar energyThe Applied Electrochemistry and Electrocatalysis Research Group at the University of Alicante has developed an Stand-alone system for the desalination and disinfection of water by Electrodialysis (ED) and the necessary water pre- and post-conditioning steps. The developed system is sustainable and environmentally-friendly being directly powered by a photovoltaic solar plant without using battery racks. This new system substantially decreases both the investment and maintenance costs by eliminating the batteries. Also, it can be adjusted to be used in water from very different sources like seawater, brackish water wells, wastewater treatment plants, industrial processes water, etc. being of particular interest for remote areas isolated from the electric grid. The Research Group has a demonstration Pilot Plant with the capacity to produce up to 1m3 of drinking water per day. The Group is looking for companies interested in the commercial exploitation of this technology through licensing agreements and/or technical cooperation.
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.
