Thermogravimetric and UV-vis spectroscopic studies of chromium redox reactions in rutile pigments
(Springer, 2009-07-01)
In this study undoped and Cr, Sb or Mo doped TiO(2) were synthesized by polymeric precursor method and characterized by X-ray diffraction, UV-VIS spectroscopy, infrared spectroscopy and thermogravimetry (TG). The TG curves ...
Contrasting effects of redox potentials on the rate constants of oxidation and hydrolysis reactions in ruthenium complexes
(Taylor & Francis, 2011-07)
We report in this work the rate constant of oxidation by peroxydisulfate of the ammine ruthenium center in [(bpy)2Ru(-5-CNphen)Ru(NH 3)5]4+ (bpy = 2,2'-bipyridine and 5-CNphen = 5-cyano-1,10-phenanthroline) and the rate ...
High energy density MnO4-/MnO42- redox couple for alkaline redox flow batteries
(Royal Society of Chemistry, 2016)
The MnO4-/MnO42- redox couple has a positive redox potential, high electrochemical reversibility and high solubility, up to 3.62 M at room temperature. Careful optimization of the electrolyte composition and the potential ...

Reactions of halonorbornane and oxo-substituted derivatives with different anions by the electron transfer mechanism; redox catalysis in stabilized radicals
(Royal Society of Chemistry, 2010-09)
Reactions of 2-bromo-, 2-chloronorbornane, 3-chloronorbornan-2-one and 3-bromocamphor with Me3Sn-, Ph2P- or PhS- ions were studied by an SRN1 mechanism in liquid ammonia or DMSO. The results show that substrates having a ...
Participação tio-redox no curso da Síndrome Metabólica de participantes de programa para mudança do estilo de vida
(Universidade Estadual Paulista (Unesp), 2018-02-22)
A prevalência mundial de Síndrome Metabólica (SM) está aumentando drasticamente nos últimos anos. Esta desordem consiste de um conjunto de condições metabólicas, contemplando hiperadiposidade abdominal, resistência insulínica ...
Redox Cycling of β-Lapachone and Structural Analogues in Microsomal and Cytosol Liver Preparations
(Elsevier Academic Press Inc, 2004-12)
The lipophilic o-naphthoquinones beta-lapachone and structural analogous quinones (CG quinones) are proposed as cytostatic, trypanocidal and antiviral agents. With rat liver microsomal NAD(P)H cytochrome P450 reductase or ...
