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

Northeastern University's Center for Research Innovation posted this:A New E-Field Writable Magnetic Random Access Memory Based on MultiferroicsCurrently, magnetic random access memories (MRAMs) use a magnetic field to control corresponding magnetic states. Such systems are comparatively bulkier and are associated with high-power consumption. With ever changing life-style; the demand for faster, smaller and ultra-low power memory systems is significantly increasing. This approach allows for the development and use of a novel electric field (E-Field) controllable MRAMs based on multi-ferroics.
UNIVERSIDAD DE ALICANTE posted this:Natural hybrids nanopigments synthesis for multiple industrial applications.The Colour and Vision Research Group of the University of Alicante has been designed a new process to develop nano-structured hybrid nanopigments (from synthetic or natural dyes). These nanopigments confer improved optical, thermal, and mechanical properties when they were applied on composite materials. The nanoclays, dyes, and additives have been selected depending on the composite matrix source. Also, it has been selected the additives order in the process of synthesis, based on the material properties that would be going to improve. The parameters that could be control with this new system are: the adsorbed dye concentration, the degradation temperature of the reinforced dye, the degradation temperature of the final nanocomposite, the bending resistant modulus, and the UV-VIS colour fastness. Also, it can be controlled the optical properties as transparency and colouring power degree. It is looking for companies interested in commercial exploitation of these new colored nanomaterials.
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 ELECTRE-H for hierarchical sets of criteria was defined by Dr. Del Vasto and Dr. Valls (from URV) and Dr. Slowinski and Dr. Zielniewicz (from Poznán University of Technology, Poland). The papers can be found here: http://www.sciencedirect.com/science/article/pii/S0957417415001153 http://link.springer.com/article/10.1007/s10844-015-0362-7 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.
