  • Patent number: 8663857
    Abstract: The present invention relates to a process for producing a continuous flow of hydrogen by catalyzed hydrolysis of a complex hydride, which comprises at least adding continuously and at constant rate a fuel solution to a reactor comprising a complex hydride stabilized on a hydroxide on a cobalt boride catalyst that is added in excess inside said reactor. Sodium borohydride is preferably used, the hydroxide is sodium hydroxide and the catalyst is supported on nickel foam. Parameters and optimal conditions to achieve continuous production of hydrogen have been determined, which is essential in the operation of fuel cells. A facility comprising a semi continuous reactor designed to perform the above process, which needs no refrigeration is also an object of the present invention, as well as a washing and reactivation process of a catalyst of the type used in the process mentioned above.

  • Patent number: 8463397
    Abstract: A hyperthermia device comprising a generator of radio-frequency electromagnetic fields, an amplifier of this signal, a transmitter of the electromagnetic field generated, and a direct temperature measurement system is disclosed for use with one or more nanoparticles capable of dissipating the energy of the applied electromagnetic field in the form of heat and it being possible to directly control the temperature of said nanoparticles.

  • Patent number: 7960025
    Abstract: The invention relates to nanoparticles of noble metals, having a controlled microstructure which leads to the appearance of ferromagnetic behaviour in said nanoparticles, thereby enabling the use of very small magnets (<5 nm) in a range in which standard ferromagnetic metals behave as superparamagnetic entitles (disappearance of hysteresis cycle). The inventive nanoparticles can be used, for example, to reduce the dimensions in magnetic recordings, as well as in biomedicine as tools for biomolecule recognition, nuclear magnetic resonance imaging, drug-release control or hypothermia treatments.
