Scavenging of the one-electron reduction product from nisoldipine with relevant thiols: Electrochemical and EPR spectroscopic evidences
(1998)
Purpose. To determine the formation of the one-electron reduction product from nisoldipine and its reactivity with relevant thiols in mixed medium. Methods. Cyclic voltammetry (CV) and electron paramagnetic resonance (EPR) ...
Spectroscopic characterization of the reduction and removal of chromium (VI) by tropical peat and humin
(Elsevier B.V., 2012-01-01)
The reduction of Cr(VI) to Cr(III) in aqueous solution, and the subsequent removal of Cr(III) using in natura peat or its humin fraction, was characterized by electron paramagnetic resonance (EPR), ultraviolet-visible ...

EPR spectroscopy applied to the study of the TEMPO mediated oxidation of nanocellulose
(Elsevier, 2015-09-30)
Two different methods of pH control were used in the synthesis of 2,2,6,6-tetramethylpiperidine-1-oxyl(TEMPO) oxidized cellulose nanocrystals (CNC) and the reaction kinetics and degree of oxidation wereinvestigated. In ...

(Amer Inst PhysicsMelvilleEUA, 2009)
Estudo espectroscópico de compósito obtido da reação no estado sólido entre um complexo mononuclear de vanádio(IV) e caulinita
(Brasil, 2012)
The use of probes, such as paramagnetic species diluted in diamagnetic materials in EPR spectroscopy, and mathematical tools such, as the Kubelka-Munk function in DRUV-VIS spectroscopy are strategies in the analysis of ...
Cofactor composition and function of a H 2 -sensing regulatory hydrogenase as revealed by Mössbauer and EPR spectroscopy
(Royal Society of Chemistry, 2015-05)
The regulatory hydrogenase (RH) from Ralstonia eutropha H16 acts as a sensor for the detection of environmental H2 and regulates gene expression related to hydrogenase-mediated cellular metabolism. In marked contrast to ...
13C NMR and EPR spectroscopic evaluation of oil shale mined soil recuperation
(Sociedade Brasileira de Química - SBQSão Paulo, 2013)
Neste trabalho foram analisadas amostras de matéria orgânica de solos (MOS) de área de floresta nativa (SFN) e de solos de uma área vizinha, local de mineração de xisto, que vem sendo reabilitada há 30 anos (SFR). As ...
