Energy requirements during butanol production and in situ recovery by cyclic vacuum
(Pergamon-elsevier Science LtdOxfordInglaterra, 2012)
Self-assembly of the cyclic dimer [Cu(hfac)(2)(bpmu)](2) (bpmu = N,N '-bis(3-pyridylmethyl)urea; hfac = hexafluoroacetylacetonate ion) using coordination chemistry and predictable O = C(N-H)(2)center dot center dot center dot O=C hydrogen bonds
(ELSEVIER, 2005-06)
A novel binuclear metallacyclic complex, [Cu(hfa)(2)(bpmu)](2), was isolated by reacting copper(II) hexafluoroacetylacetonate with the bpmu ligand. The crystal structure reveals the presence of dimetal units with the Cu(II) ...
Cyclic voltammetric behaviour of the O-2/O-2(center dot-) redox couple at a HMDE and its interaction with nisoldipine
(ELSEVIER SCIENCE, 2002-02-08)
We have studied the O-2/O-2(.-) redox couple on the HMDE in DMSO aprotic media, obtaining optimal conditions of both oxygen concentration and scan rate in order to avoid oscillatory phenomena. By choosing the oxygen ...
Limit cycles in 4-star-symmetric planar piecewise linear systems
(Elsevier B.V., 2020-02-15)
Our interest is centered in the study of the number of limit cycles for nonsmooth piecewise linear vector fields on the plane when the switching curve is xy=0. We consider the symmetric case. That is, one vector field ...
Electropolymerization mechanism in aqueous solution of the oxo-manganese complex biomimicking of the enzymatic center present on the photosystem II
(2012-12-01)
The [Mn4 IVO5(terpy)4(H 2O)2]6+ complex, show great potential for electrode modification by electropolymerization using cyclic voltammetry. The electropolymerization mechanism was based on the electronic transfer between ...

Electrochemical and ESR study of 5-nitrofuryl-containing thiosemicarbazones antiprotozoal drugs
(PERGAMON-ELSEVIER SCIENCE LTD, 2005-10)
Cyclic voltammetry and electron spin resonance (ESR) techniques were used in the investigation of several potential antiprotozoal thiosemicarbazones nitrofurane derivatives.
A self-protonation process involving the ...
Teoria dos centros e ciclicidade de pontos de Hopf para campos de vetores planares e tridimensionais
(Universidade Estadual Paulista (Unesp), 2019-07-17)
Neste trabalho, estudamos o Problema do Centro-Foco para sistemas planares e sua extensão para sistemas tridimensionais apresentando alguns dos resultados mais recentes da literatura. Nosso enfoque envolve duas abordagens ...
