The process is carried out in the absence or presence of some solvent, during the process of the current invention, temperature may be or may be not used as catalyst, in the process of the current invention the reaction may be or may not be catalyzed by the presence of a catalyst (acid or base), the resultant products can be produced and separated in an easy way, in the process of the current invention starting from pyridinic alcohols the resultant ethenediols can be produced by a single step reaction. The pyridinemethanol derivatives used as starting compounds, do not oxidize as easily and their handling is easier than that of other compounds. The products produced with etheneidol parts can be used as antioxidants due to their capacity to act as free radicals scavengers.

The particles have an irregular shape and variable size for filling columns of different diameter and length. The adsorbent has sufficient hardness for avoiding a particle collapse. The material does not rot, is re-generable and ecological. In the present invention the preparation of the adsorbent, its pre-activation, carbonization and application to eliminate the color of textile wastewater is disclosed.; The color elimination from textile wastewater, as well as decrease of salts, total suspended solids, chemical oxygen demand (COD) and total organic carbon (TOC), is carried out passing the textile wastewater through a column filled with the prepared adsorbent. In batch systems metals dissolved in water can be eliminated.

UATEC - Unidade de Transferência de Tecnologia posted this:Lighting device with adjustable white light based on zirconia nanostructuresA group of researchers from a Portuguese university has developed the concept of a lighting device with adjustable white light based on zirconia nanostructures. The invention aims to control the color temperature of white light emission that is different depending on the morphology/dimension of the particles, on the surrounding environment and on excitation power. The advantage of this type of device is based on the high color quality index and the possibility of color temperature control that is relevant to the lighting technologies market. The university is looking for companies that develop this type of solution on an industrial scale. The university is looking for companies that develop this type of solution on an industrial scale for the further joint development of specific applications or technology licensing.
UATEC - Unidade de Transferência de Tecnologia posted this:Optical pressure sensor based on zirconia nanostructuresA group of researchers from a Portuguese university has developed the concept of a gas pressure gauge based on the control of the luminescence from zirconia nanostructures. The invention aims to measure the gas pressure based on the nanoparticles emission that is different depending on the amount of gas molecules surrounding the nanoparticles. Comparing with existing solutions, the advantage of this process, which operate in a pressure range of interest for various market sectors (ex. Food industry), is the absence of electrical contacts. The university is looking for companies that develop this type of solution on an industrial scale for the further joint development of specific applications or technology licensing.
Universidad de Alcalá-OTRI posted this:New organo-metallic catalysts for the manufacture of polymersA research group from the Inorganic Chemistry Department of Alcalá University has developed a technology that presents a range of catalysts based on coordination complexes and organometallic, active in functionalization processes (expoditation, hydrosilylation) and polymerization of different organic substrates (olefins and cyclic esters). They are metal complexes belonging to the first transition groups (groups 4-6) and elements from the main groups (groups 1,2 and 13). Its application is aimed at the synthesis of materials with new properties (silicon polymers, biodegradable plastics, polyesters) and the production of small molecules with high added value, used as starting products in many industrial processes (epoxides, silanes). The group is looking for manufacturing agreements and joint venture agreements with companies from the agrofood industry, construction and petrochemicals.
