Complex numbers-partial least-squares applied to the treatment of electrochemical impedance spectroscopy data
(Elsevier Science, 2019-11)
This work investigated the application of partial least-squares regression of complex numbers on multivariate data obtained by electrochemical impedance spectroscopy (EIS). The use of complex numbers–PLS was evaluated in ...
Efeito de dihidroxibenzenos na degradação de fenóis e fármacos por processos Fenton
(Universidade Estadual Paulista (Unesp), 2017-03-03)
Os fármacos são detectados em ambiente aquático em concentrações que variam de ng L-1 a g L-1 e não são completamente removidos no tratamento convencional de águas residuais. Um dos Processos Oxidativos Avançados utilizados ...
Kinetic role of a histidine residue in the T1 copper site of the laccase from Rigidoporus lignosus
(Elsevier B.V., 2014-01-01)
Laccases (benzendiol:oxygen oxidoreductases; EC 1.10.3.2) catalyze the oxidation of a broad range of substrates, such as polyphenols, dyes and pollutants, and thus these enzymes are widely applied in industrial, biotechnological ...
Pulp mill effluent treatment by fenton-type reactions catalyzed by iron complexes
(IWA PUBLISHING, 1999)
Fenton reaction, which involves hydrogen peroxide and ferrous ion, has been proposed as an efficient option for effluent treatment. In this work, the treatment of a pulp bleaching effluent using Fenton-type reactions ...
Hydroxyl radical production by heterogeneous Fenton reaction supported in insoluble tannin bark of Pinus radiata
(2016)
Fenton reactions driven by dihydroxybenzenes (DHBs) have been used for pollutant removal via advanced oxidation processes (AOPs), but such systems have the disadvantage of DHB release into the aqueous phase. In this work, ...
Melanins in fungi: Types, localization and putative biological roles
(Academic Press Ltd - Elsevier Science Ltd, 2017-08)
Melanin is a secondary metabolite made up by complex heterogeneous polymers. Several classes of fungal melanins have been described like γ-glutaminyl-3,4-dihydroxy-benzene (GDHB)-, L-DOPA-(eumelanin), DHN-, catechol-melanin, ...
Synthesis of bis(trimethylstannyl)aryl compounds via an SRN1 mechanism with intermediacy of monosubstitution products
(American Chemical Society, 2002-12)
1,2-Bis(trimethylstannyl)benzene (1) and 2,2′-bis(trimethylstannyl)-1,1′-binaphthyl (2), useful as intermediates in the preparation of bidentate Lewis acids, have been synthesized from simple phenols through a two-step ...
