Low cost: obtained by a chemical process of a single stage, with a single precursor, at low temperature, and highly available, non-polluting and low cost materials. Good cyclability: testing in cyclability is promising in terms of electrochemical and mechanical stability. In parallel to its advantages as supercapacitors, the nanocomposites show the advantages associated with the following additional properties: Giant magnetoresistance, GMR: this property is observed at room temperature, and high magnetic fields are not needed. Source of carbon nanoforms: based on the nanocomposite, can be obtained a mixture of carbon nanoforms consisting of nano-onions and multi-walled nanotubes.

The group is looking for companies interested in acquiring the technology for commercial exploitation. Innovative aspects The inclusion of waste plastic (EVA, polyethylene, polyurethane, polypropylene, polymer melt, foam, rubber, etc. Or any combination thereof) in the composition, permits its recycling in a simple and cheap, and that current procedures are difficult and very expensive. Together with a chemical foaming and dispersion of ferrites in the composition, applies the energy necessary for the cohesion of the materials by microwave. Ferrites dispersed in the mixture capture and transmit microwaves heat required for foaming in every part of the obtained mass. With this new procedure, getting pieces of great uniformity, stability and thickness that determines the user (up to 25 cm. in diameter) at a low cost and quick way.
Universidad de Alicante posted this:New method for evaluating the durability of concrete by using conductive gelsThe main system innovation is the use of ion conductive gels as reservoirs of chlorides in migration assays. Until now the techniques had to start with the full saturation of the specimen and keeping it in contact with a chloride ions solution during diffusion or migration tests. This guaranteed the absence of other transport mechanisms (such as capillary absorption) and avoided surface moisture changes. This new method is simple to implement and allows the elimination of these requirements. Another innovative feature is that the system allows greater measuring accuracy of the advancing chloride front, because this advance occurs more homogeneously than in conventional tests in contact with liquid solutions.

It is ap-proximately 1.5 times greater than the friction produced by conventional mesh systems or with titanium or cobalt-chromium spherules, achieving an excel-lent primary stability of the implant.

It is very simple: it improves ergonomics, avoids rubbing, it is easy to use (the suit can be worn throughout the day) and is designed to avoid injuries and pathologies and increase training time. The suit has weighted segments arranged proportionally over all the different parts of the user’s body (the exact arrangement is determined by personalised anthropometric studies). The group is seeking companies interested in acquiring and using the technology. Innovative features: The suit is fitted with weighted segments arranged proportionally over the different parts of the user’s body, leaving the head, hands, feet and main joints free. Each segment is allocated a greater or lesser load according to the user’s needs and the activity to be carried out. The arrangement of the weights is determined by personalised anthropometric studies using the Marfell-Jones methodology. The suit is ergonomic and avoids rubbing, is easy to use (it allows muscle development while the user is not training, thus saving time) and, most importantly, does not cause injuries or pathologies.
