Centre Technology Transfer CITTRU posted this:The subject of the offer is new nonlinear optical materials for use in optoelectronics, optical devices and components.Along with the dynamic development of optical technology, there is an increasing interest in materials characterized by high birefringence and high efficiency of generating the second harmonic. The presented offer relates to co-crystals, from which one of polymorphic form is an efficient, phase matchable second harmonic generator. The averaged, relative experimental of second harmonic generation is over 14 times higher than of the commonly used nonlinear material (potassium dihydrogen phosphate). The presented optical material is colorless, suitable for growing large single crystals. The obtained crystals have extreme values of birefringence with reference to other transparent materials. The maximum birefringence for one of the polymorphic form is 0,46. For comparison, calcite, which is commonly used for the production of polarizing prisms, has a birefringence c.a 0.17. The offered materials, thanks to their properties, may be used for the construction of optical devices and components. Moreover, due to the polar structure may exhibit properties such as pyroelectricity, piezoelectricity or ferroelectricity.
University of Huelva posted this:Manual Handler of Concrete SleepersThe machine was designed to disengage steel bars from prefabricated concrete sleepers manually, which allows to increase production, safety at work and to improve the technical properties of the final product. The stretcher has two benches that allow movement in two directions, longitudinal and trasnverse. The process is done in such a way that the four active screws are de-stressed at the same time, avoiding damages.

Cracow University of Technology posted this:Sintering technique for both high density and high precision of steel-based sintersThe invention relates to the special additions that may be introduced to virtually any powder mixture based on steel aimed for sintering process. Specifically, the additions result in increased density (mainly of 0.5-0.7 g/cm3) of a final sinter accompanied with both high dimensional precision and increased corrosion resistance. Also, the invention decreases the sintering time down to 30 minutes. Application of this technology do not require modification of machine park and may easily utilized by anyone already sintering steel components.

Cracow University of Technology posted this:Permanent antimicrobial properties on textile materials by staining them with modified indigo dyeThe inventionconcernsthe technology of modifying dyeing substance by binding it with antimicrobial agent. In particular, silver or zinc oxide nanoparticles are embedded into the structure of indigo dye. As-modified colouring agent serves to dyeingthe textile material which in turn gets constant antimicrobial properties.The advantage over existing technologies is due to the fact that silver nanoparticles are obtained in-situ in the process of formation indigo dye. Using environment friendly substances makes that the technology is safe.

The captured oil can be extracted and recycled, and the product can be reused several times over. These products can be developed as powders or granules with varying levels of hardness, water resistance, size, and density for diverse set of applications.
University of Huelva posted this:New method for manufacturing magnetic cores by powder metallurgyMagnetic cores in amorphous state are usually produced by placing together very thin amorphous ribbons from a material obtained by the melt-spinning technique. The new patented method produces the amorphous material by mechanical alloying, a traditional process in the powder metallurgy field. This technique allows a higher control on the amorphisation process and the properties of the amorphous obtained powders. These powders are then consolidated by the very quick process known as Electrical Resistance Sintering (also Electrical Discharge Consolidation/Sintering can be used). A final amorphous material, without the typical frontier between ribbons of melt spinned materials, which clearly affect properties, is obtained.
University of Huelva posted this:New method for manufacturing powder metallurgy magnetsThe conventional method of press followed by furnace sintering is now substituted by an electrical consolidation method. This allows joining in a single step the previous pressing/sintering processes, and, due to the promptness of the process, the use of controlled atmospheres is not necessary. The steps of magnetization, and eventual thermal treatments, can be carried out in the same container, without being necessary to manipulate the product.
UNIVERSIDAD DE ALICANTE posted this:Production of briquettes for energy recovery of furniture waste with polyurethane foamsThe Research Group "Waste, energy, environment and nanotechnology" (WEEN) from the University of Alicante has developed a new compact material and a production process of briquettes of furniture waste. This process makes it possible to carry out the management and the energy recovery of this waste, avoiding the environmental problems associated with its landfilling and also making it easier to transport, handle and store. The briquettes obtained, show physicochemical characteristics similar to the conventional and they have a high energy density being able to be used as fuel for thermal power plants or industrial boilers. Companies in the waste treatment sector and the furniture industry that are interested in commercial exploitation of this technology through licensing agreements and / or technical cooperation are sought.

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
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.
