Preparation and characterization of a supported system of Ni2P/Ni12P5 nanoparticles and their use as the active phase in chemoselective hydrogenation of acetophenone
(IOP Publishing, 2018-03-26)
Ni2P/Ni12P5 nanoparticles were obtained by thermal decomposition of nickel organometallic salt at low temperature. The use of different characterization techniques allowed us to determine that this process produced a mixture ...
Estudio de los "NI-NI" del Gran Córdoba a través de un modelo de regresión logística
(2017-10)
Si bien la trayectoria juvenil hacia la adultez se observan cada vez más heterogénea y compleja, es esperable que en esta etapa de la vida los jóvenes transiten por ciertos eventos claves que incluyen, entre otros, la ...
Effect of the catalyst preparation method on the performance of Ni-supported catalysts for the synthesis of saturated amines from nitrile hydrogenation
(Elsevier, 2019-09)
The liquid-phase hydrogenation of butyronitrile to saturated amines was studied on silica-supported Ni catalysts prepared by either incipient-wetness impregnation (Ni/SiO2-I) or ammonia (Ni/SiO2-A) methods. A Ni/SiO2-Al2O3-I ...
Effect of mechanical coating with Ni and Ni-5% Al on the structure and electrochemical properties of the Mg-50% Ni alloy
(SPRINGER, 2008)
The Mg-Ni metastable alloys (with amorphous or nanocrystalline structures) are promising candidates for anode application in nickel-metal hydride rechargeable batteries due to its large hydrogen absorbing capacity, low ...

Caracterização das ligas Ni-Ti-Mo, Ni-Ti-Ta e Ni-Ti-Mo-Zr obtidas por moagem de alta energia e prensagem a quente
(Universidade Estadual Paulista (Unesp), 2011-07-21)
O Brasil ainda não produz a liga Ni – Ti em escala comercial, importando grande parte dos produtos à base de Ni – Ti voltados à área médica. O grande custo envolvido na importação destes produtos estimula a tentativa de ...

Evaluation of Ni0, NiO, and NiS as a Cocatalyst Modifier on TiO2Nanotubes Matrix for the Enhancement of Photoelectrocatalytic Oxidation of Penicillin G
(2021-07-01)
The development of an effective cocatalyst for the modification of TiO2 arrays has become highly desirable for the improvement of their photoelectrocatalytic properties. We investigated the modification of TiO2 with ...
New Ni(II)-sulfonamide complexes: Synthesis, structural characterization and antibacterial properties. X-ray diffraction of [Ni(sulfisoxazole)(2)(H2O)(4)] center dot 2H(2)O and [Ni(sulfapyridine)(2)]
(Elsevier B.V., 2008-02-01)
The synthesis, structural characterization, voltammetric experiments and antibacterial activity of [Ni(sulfisoxazole)(2)(H2O)(4)] center dot 2H(2)O and [Ni(sulfapyridine)(2)] were studied and compared with similar previously ...
