[ES] El tecnecio-99m (99mTc), el radioisótopo más importante en la medicina nuclear de diagnóstico, se utiliza para aproximadamente 35 millones de procedimientos por año. Una gran parte del éxito de 99mTc radica en su ...
Compressibility and structural stability of ultra-incompressible bimetallic interstitial carbides and nitrides

Errandonea, D.; Ruiz-Fuertes, J.; Sans, J. A.; Santamaría-Perez, D.; Gomis Hilario, Oscar; Gómez, A.; Sapiña, F. (American Physical Society, 2012-04-06)

We have investigated by means of high-pressure x-ray diffraction the structural stability of Pd 2Mo 3N, Ni 2Mo 3C 0.52N 0.48, Co 3Mo 3C 0.62N 0.38, and Fe 3Mo 3C. We have found that they remain stable in their ambient-pressure ...
Dehydroaromatization of methane under non-oxidative conditions over bifunctional Mo/ITQ-2 catalysts

Martinez Feliu, Agustin; Peris Chanzá, Ernesto José; Sastre Navarro, German Ignacio (Elsevier, 2005-10-30)

[EN] Bifunctional Mo/ITQ-2 catalysts have been used for the methane dehydroaromatization (MDA) reaction. The Si/Al ratio, and thus the Brønsted acidity, of the zeolite affected the conversion, the formation rate of ...
Enhanced Photocatalytic Activity and Stability in Hydrogen Evolution of Mo(6)Iodide Clusters Supported on Graphene Oxide

Puche Panadero, Marta; García-Aboal, Rocío; Mikhaylov, Maxim A.; Sokolov, Maxim N.; Atienzar Corvillo, Pedro Enrique; Feliz Rodriguez, Marta (MDPI AG, 2020-07)

[EN] Catalytic properties of the cluster compound (TBA)2[Mo6Ii8(O2CCH3)a6] (TBA = tetrabutylammonium) and a new hybrid material (TBA)2Mo6Ii8@GO (GO = graphene oxide) in water photoreduction into molecular hydrogen were ...
Estudio de la modificación superficial por láser de aleaciones pulvimetalúrgicas de titanio para la mejora de su comportamiento mecánico y químico

Tendero Lozano, Inmaculada (Universitat Politècnica de València, 2019-10-21)

[ES] La amplia utilidad del titanio en el campo de la biomedicina es debida a sus propiedades de biocompatibilidad, osteointegración y resistencia a la corrosión. Sin embargo, deben abordarse los dos problemas principales ...
Estudio de las transformaciones superficiales en aleaciones Ti-35Nb-2Sn y Ti-25Nb-8Mo procesadas mediante técnicas láser

Tyutyunik, Sofya (Universitat Politècnica de València, 2022-11-09)

[ES] Las aleaciones de Titanio (Ti) tienen una gran importancia en numerosas industrias. En particular, son los metales más utilizados para aplicaciones biomédicas. La aleación más común, Ti6Al4V tiene desventajas de ...
Flexible CuInSe2 photovoltaic cells fabricated by non-vacuum techniques

Samantilleke, Anura Priyajith; Sahal, Mustapha; Ortiz Moya, Laura; Cerqueira, M.F.; Marí Soucase, Bernabé (Elsevier, 2011-08)

In this work, CuInSe 2 based flexible photovoltaic cells have been fabricated completely using non-vacuum low-cost techniques. Thin films were deposited on molybdenum thin foil substrates by electrodeposition using a ...
