Journal ArticleDOI
Effect of surface and porosity of biochar on water holding capacity aiming indirectly at preservation of the Amazon biome.
Estela M.C. Cardoso Batista,Juliana Shultz,Tassya Thaiza da Silva Matos,Mayara Regina Fornari,Thuany M. Ferreira,Bruno Szpoganicz,Rilton Alves de Freitas,Antonio S. Mangrich,Antonio S. Mangrich +8 more
TL;DR: The results suggested that despite the effect of porosity on water retention, the zeta potential could be associated with the presence of negative charges by which hydrated cationic counterions were absorbed and retained.
Journal ArticleDOI
Lessons from the Terra Preta de Índios of the Amazon region for the utilisation of charcoal for soil amendment
Etelvino Henrique Novotny,Michael H. B. Hayes,Beata Emoke Madari,Tito José Bonagamba,Eduardo Ribeiro de Azevêdo,Andre Souza,Guixue Song,Christiane M. Nogueira,Antonio S. Mangrich +8 more
TL;DR: The potential of charcoal and partially combusted organic waste to mimic the soil organic matter of the Terras Pretas de Indios (Amazonian Dark Earths) from the Amazon Region is discussed in this article.
Journal ArticleDOI
A new dinuclear unsymmetric copper(II) complex as model for the active site of catechol oxidase
Christiane Fernandes,Ademir Neves,Adailton J. Bortoluzzi,Antonio S. Mangrich,Eva Rentschler,Bruno Szpoganicz,Erineu Schwingel +6 more
TL;DR: In this paper, the crystal structure, magnetic, redox and spectroscopic properties of a novel unsymmetrical dinuclear copper(II) complex, prepared by the reaction between copper (II) perchlorate, sodium acetate and the binucleating ligand, where HTPPNOL is N,N,N′-tris-(2-pyridylmethyl)-1,3-diaminopropan-2-ol, is reported.
Journal ArticleDOI
Electrochemical determination of copper ions in spirit drinks using carbon paste electrode modified with biochar
Paulo Roberto de Oliveira,Alyne Lamy-Mendes,Edivaltrys Inayve Pissinati de Rezende,Antonio S. Mangrich,Luiz H. Marcolino,Márcio F. Bergamini +5 more
TL;DR: Determination of copper ions content in different samples of spirit drinks samples was also realized adopting inductively coupled plasma optical emission spectroscopy (ICP-OES) and the results achieved are in agreement at a 95% of confidence level.
Journal ArticleDOI
Phosphate diester hydrolysis and DNA damage promoted by new cis-aqua/hydroxy copper(II) complexes containing tridentate imidazole-rich ligands.
Marciela Scarpellini,Ademir Neves,Rosmari Hörner,Adailton J. Bortoluzzi,Bruno Szpoganics,César Zucco,René A. Nome Silva,Valderes Drago,Antonio S. Mangrich,W.A. Ortiz,W. A. C. Passos,Mauricio C. B. De Oliveira,Hernán Terenzi +12 more
TL;DR: The tridentate Schiff base and its reduced form HISMIMA were synthesized and characterized and their mononuclear cis-dihalo copper(II) complexes 1 and 2, respectively were investigated by infrared, electronic, and EPR spectroscopies, cyclic voltammetry, and potentiometric equilibrium studies.
