Electrochemical evidences of the inhibitory action of propargyl alcohol on the electrooxidation of nickel in sulfuric acid
(1998) [Journal article]Neste trabalho são apresentados os resultados dos estudos do comportamento eletroquímico do eletrodo de níquel em H2SO4 1,0 N, na ausência e na presença de álcool propargílico (Propin-2-ol-1). Observou-se uma forte interação ... -
Friedel-crafts alkylation of toluene as a parallel reaction in propylene dimerization catalyzed by nickel β-diimine complex/easc in homogeneous phase
(2015) [Journal article]A oligomerização do propeno foi realizada utilizando o complexo dibromo-bis(N,N’- difenilpentano-2,4-diimina)niquel(II) como precursor catalítico combinado ao sesquicloreto de etilalumínio (Al2Et3Cl3, EASC) como co-catalisador. ... -
A FTIR study of the metal-support interactions and hydrogen spillover on Pd/TiO2 and Ni/TiO2
(2002) [Journal article]Nickel and palladium dispersed on titania support were submitted to reductive treatment, under hydrogen, at 200 and 500 ºC. After the reductive thermal treatment the materials were exposed to carbon monoxide (10 Torr) and ... -
Styrene polymerization by nickel and titanium catalysts based on tris(pyrazolyl)borate ligands
(2008) [Journal article]A polimerização do estireno com uma série de complexos de níquel e titânio contendo ligantes tris(pirazolil)borato estericamente impedidos, TpMs = HB(3-mesitila-pirazolil)3 e TpMs* = HB(3-mesitila-pirazolil)2(5-mesitila-pirazolil) ... -
Synthesis of magnetic nanoparticles functionalized with histidine and nickel to immobilize His-tagged enzymes using β-galactosidase as a model
(2021) [Journal article]The aim of this study was to synthesize iron magnetic nanoparticles functionalized with histidine and nickel (Fe3O4-His-Ni) to be used as support materials for oriented immobilization of His-tagged recombinant enzymes of ...
