Cracow University of Technology posted this:Photosensitizers for photocurable polymer coatingThe technology can be used in the production of polymer coatings curable by ultraviolet radiation (UV) imposed on various types of surface such as aluminum, paper, plastics, wood and metals. Technology is compatible with UV LED diodes, which make it advantageous in several fields comparing to traditional mercury MPM lamps
UATEC - Unidade de Transferência de Tecnologia posted this:Ohmic heating reactor for chemical synthesis, the method and its applicationsIn ohmic heating electrical energy is dissipated in heat with a very high efficiency (electrodes in contact with the reaction medium), resulting in fast and uniform heating and in the increase of charged species movement. As in the case of the heating with microwave radiation, electrical energy is transformed into thermal energy. However, on contrary of heating with microwave radiation (penetration depth of microwave radiation in absorbing media is limited) the penetration depth is virtually unlimited and the extent of heating is regulated only by the spatial uniformity of electrical conductivity throughout the reaction medium and the time spent in the ohmic reactor. Thus, the direct scaling of the ohmic heating for the pilot or industrial scale shouldn’t have the limitations presented by microwave radiation heating. It is also possible to reduce reaction times and increase the energy efficiency of chemical reactions
University of Vigo posted this:A novel mild and efficient method to prepare ε-Caprolactam precursor of Nylon 6ε-Caprolactam, the main precursor of the synthetic fibber Nylon 6, is prepared from cyclohexanone oxime by treatment with a new salt as promoter. This procedure requires mild reaction conditions and affords excellent levels of conversion and selectivity to obtain pure ε-caprolactam. No reaction by-products are formed. The new promoter salt is cheap, no corrosive, and easy to prepare. All these characteristics makes the procedure suitable for undustrial purposes.

Universidad de Alcalá-OTRI posted this:Carbosilane dendritic compounds homo and heterofunctionalizedA Spanish research group from the Department of Organic and Inorganic Chemistry of Alcala University has developed a highly branched macromolecules called dendrimers or dendrons, with carbosilane structure and functionalized on its periphery with anionic or cationic groups, providing the macromolecule a net negative or positive charge respectively. The invention also concerns the dendrimers’ procurement process and their biomedical applications, particularly as carriers of drugs or nucleic acids (such ODN, siRNA, dsRNA or DNA), or as therapeutic agents with antiviral or antibacterial activity. The group is looking for companies in the biomedical sector to reach licensing agreements, collaboration and commercial agreements with technical assistance.
Centre Technology Transfer CITTRU posted this:Ecological solid fuel additive, which improve fuel combustion efficiency and decrease soot generation.Solid fuel eco-additive reduces soot production and deposition on chimney walls, flues and boiler installation. Moreover it doesn't cause boiler corrosion. Consequently it improves boiler thermal efficiency and fuel combustion effectiveness. That means lower costs of heating. It also modifies soot to be biodegradable, prevents releasing soot-related pollutions and isn't harmful to human health.
Institute of Chemical Research of Catalonia posted this:ERTFlow: flow reaction technologies and process intensificationERTFLOW is a technology development unit from the Institute of Chemical Research of Catalonia (ICIQ), generated by the know-how produced by the research group of Prof. Miquel Pericàs, to develop and implement technical solutions in process intensification. Our goal is to develop propietary technologies related to catalysis and flow chemistry and offering products and services to the fine chemical, pharmaceutical and biotechnological industries for the production of new products with high added value and guide them in the paradigm change from batch to flow.
Institute of Chemical Research of Catalonia posted this:New method to produce trifluoromethyl copper reagents useful in trifluoromethylation reactions from fluoroformThe trifluoromethyl copper derivative useful in trifluoromethylation reactions is prepared at room temperature from readily available and cheap reagents and in high yield, i.e. without the formation of side-products associated to the fast decomposition of the trifluoromethyl anion, that usually forms in processes involving the deprotonation of fluoroform. This is the first method to date for deprotonation-free, direct cupration of fluoroform, a longly sought after reaction.
