Fundació URV posted this:Environmentally friendly processing of thermosets by two-stage sequential aza-Michael addition and free-radical polymerization of amine-acrylate mixturesEnvironmentally friendly preparation of thermosets for applications on thermosensitive substrates. A two-step curing process, which consists in an Aza-Michael addition at room temperature, followed by UV radical polymerization of acrylates or methacrylates amine formulations without the need of adding solvents. The presence of amines in the structure suppress the radical inhibition by oxygen, which is a typical drawback in radical polymerizations. The invention allows leading the curing in two separate stages with a stable intermediate material, being the process controlled by the amount of amine in the formulation.
Fundació URV posted this:ELECTRE-H software package: a tool for data analysis and decision aiding with hierarchical criteriaThe ELECTRE-H Software Package implements two new methods for ranking and ordered classification decision problems considering multiple criteria structured into a hierarchy. The hierarchy of criteria is a tool that allows the decision maker to better organize the problem based on its domain knowledge and needs, decomposing the general problem into smaller sub-problems. Both methods follow the well-known outranking model and belong to the family of ELECTRE methods. The ELECTRE approach is inspired on the voting-like procedure based on the opinion of the majority but also respecting the minorities (by allowing veto power). The software available to use ELECTRE methods does not allow a hierarchical decomposition of the problem, but on a flat organization of criteria. The novelties of these two methods are the following: -It fully applies the standard outranking procedure of ELECTRE at all the levels of the hierarchy of criteria (concordance and discordance indices are obtained from the results of the previous layer and exploited at each node to generate new results). -The user will get a result (a ranking or classification) at each intermediate node of the hierarchy as well as the root (or overall) node. -Preference uncertainty can be managed at each node of the hierarchy with its particular discrimination threshold values. -Veto power can be given to the appropriate nodes in the hierarchy, to avoid compensation with the rest of related criteria. -Different scales of measurement can be used both in the elementary criteria and in the intermediate criteria. -For the case of sorting, simple IF…THEN… decision rules are used to define the categories. The novelty of the software ELECTRE-H is that it is the implementation of these methods given by the authors. This guarantees that the program is fully following the methodology proposed. Its main features are: -Clear and easy-to-understand user interface. -Data can be easily provided using an Excel file. -All the parameters of the model can be easily changed in the user interface. -The results obtained can be graphically displayed (i.e. partial pre-orders, rankings) and exported into a PNG image or text files. Also, the calculations of the results are provided in log files. -Additional statistical tools to compute correlations for different ranking and classification results on the same set of alternatives and hierarchy are available. -A distance-based statistical tool to compare partial preorders is available. -The “Simos revised procedure” to calculate numerical values for criteria weights is available. -Analysis of the results can be done at different levels of the hierarchy. -The software supports large number of alternatives and criteria. Also the structure of the hierarchy is only limited to be a tree (each node has a single parent). The software is designed to be easy to use while providing the full functionality required in these two methods.

UNIVERSIDAD DE ALICANTE posted this:Novel and simple procedure for dispersing graphene derivatives in chemically curable resins.The Laboratory of Adhesion and Adhesives of the University of Alicante and the company Dental Global Training, have developed a new procedure to incorporate efficiently graphene derivatives (nanofibers, nanosheets, nanoparticles) in chemically cured resins by using an in situ polymerization technique. The method is very simple and fast, it provides an excellent dispersion of the graphene derivatives in both the solid components of the resin and in the cured polymer matrix, and is entirely friendly with the environment. The novel method does not require the use of organic solvents nor water, ultrasounds, and high pressure/temperature. The resulting resin composites show excellent mechanical properties, good wear resistance, easy manipulation and increase the insolubility in oral fluids, and therefor they have special interest in applications in odontology, traumatology and non-medical applications too (automobile, construction, civil engineering, aeronautics, space engineering, electronics and optics). It is looking for companies interested in acquiring this technology for its commercial exploitation.
UNIVERSIDAD DE ALICANTE posted this:Method for recycling of vessels and other structures composed of fiberglass and resinResearchers at the University of Alicante have developed a method to recycle composite fiberglass structures on a polymer matrix (resin). The process removes the polymer matrix, recovering glass fiber which can be reused. The process is not aggressive with fiberglass. It takes place at room temperature and is able to recover all the fiberglass used. The method is industrially scalable and can be automated. Fiberglass composites and resin are widely used in the construction of boat hulls, tanks, wind turbine blades and many other applications. This method is a very important innovation for the sector and there was no effective method that allowed recovering and reusing these materials.

UATEC - Unidade de Transferência de Tecnologia posted this:Biopolymer based micro- and nanoparticlesA group of researchers from a Portuguese university developed a method for preparing new hybrid materials based on biopolymer and silica, in the form of spherical particles with uniform size and smaller than 1 micrometer for a number of applications in environmental and industrial areas. The method is also effective for coating nanoparticles of variable nature, with a thin shell (tens of nanometers) with composition identical to the hybrids. The materials have been successfully tested in the removal of chemical species in water at laboratory scale, in particular in the removal of organic pollutants dyes and pharmaceutical compounds. Other applications are being considered. The University looks for companies working in the environmental, pharmaceutical or biotechnology areas, or companies in the area of materials for licensing and / or future collaboration in developing new formulations and testing new applications.
UATEC - Unidade de Transferência de Tecnologia posted this:System for the collection , storage and exhaled alveolar air conditioning for clinical analysisA group of researchers from Portuguese university developed a device that allows the collection and storage of the exhaled alveolar air by humans. The invention aims simultaneously to overcome some of the technical difficulties in the current state of the art, such as i) little or no response in the selective collection of alveolar air fraction ii) the inability to couple systems that allow concentration/extraction of analytes of interest iii) the inexistence of systems to the storage of the collected biofluid under controlled conditions and iv) the inability to collect exhaled air in liquid or vapor state. The university is looking for companies interested in the industrial production of the equipment and its commercialization.

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.
