  • Publication number: 20150072863
    Abstract: Known processes for the production of nanoparticles of compounds of the transition metals Zr, Ti, Ta, rare earths (RE), Mn, and Fe via microemulsions lead to products that contain impurities from the reactants, particularly water, which make the further use of said nanoparticles difficult, for instance in high-temperature super conductors (HTSC). It is proposed that the nanoparticles be produced via anhydrous microemulsions having an outer phase composed of a nonpolar solvent and inner phase composed of a polar anhydrous solvent. The nanoparticles thus obtained exhibit good monodispersity and can be used in the production of REBa2Cu3O7 super conductors by incorporation into the precursor coating solution.

    Abstract: The invention relates to the field of production of barium-scandate dispenser cathodes or other barium-scan-date materials. A target (66) containing a mixture of BaO, CaO, Al2O3 and SC2O3 tends to be more stable, the higher the scandia (scandium oxide) content is. However, an increased scandia content results in a reduced emission capability. A destabilizing effect of BaO and CaO reactions is counteracted by the more inert SC2O3 and also AI2O3 components, as not only an increased scandia content stabilizes the material but also an increased alumina (aluminum oxide) content improves the stability.

  • Publication number: 20130053249
    Abstract: The present invention refers to obtaining a solution of metal-organic precursors with a maximum fluorine content of 10% using the solution previously described in patent ES2259919 B1 as the starting point. This modification enables carrying out the thermal treatment of superconducting decomposition layers (pyrolysis) and crystal growth in a single stage. In addition, the low fluorine content reduces the risks of toxicity and corrosion.

  • Publication number: 20130020539
    Abstract: A novel multiband absorption based solar cell is disclosed by using the europium chalcogenides (EuX, X?O, S, Se, Te) and related magnetic semiconductor materials, in which an intermediate band is formed by the localized Eu 4f electrons between p-states of chalcogen ions and Eu s-d states. The energy gaps among the multibands can be in the spectral range of the sunlight, thus they can serve as better sunlight absorbers in solar cells than the conventional single band-gap semiconductors such as Si and GaAs. With these multiband semiconductors, the bottleneck in current power conversion efficiency can be potentially overcome in single junction photovoltaics.

  • Publication number: 20120258241
    Abstract: The feasibility of adding glass to conventional SOFC cathode contact materials in order to improve bonding to adjacent materials in the cell stack is assessed. A variety of candidate glass compositions were added to LSM and SSC. The important properties of the resulting composites, including conductivity, sintering behavior, CTE, and adhesion to LSCF and MCO-coated 441 stainless steel were used as screening parameters. The most promising CCM/glass composites were coated onto MCO-coated 441 stainless steel substrates and subjected to ASR testing at 800° C. In all cases, ASR is found to be acceptable. Indeed, addition of glass is found to improve bonding of the CCM layer without sacrificing acceptable conductivity.
