One-pot synthesis of amine-functionalized graphene oxide by microwave-assisted reactions: an outstanding alternative for supporting materials in supercapacitors
C. C. Caliman,A. F. Mesquita,Daniel F. Cipriano,Jair C. C. Freitas,Alexandre A. C. Cotta,Waldemar A. A. Macedo,A.O. Porto +6 more
TL;DR: In this article, a simple and straightforward method using microwave-assisted reactions is presented for the functionalization of graphene oxide with aromatic and non-aromatic amines, notedly dibenzylamine (DBA), p-phenylenediamine (PPD), diisopropylamine(DPA), and piperidine (PA).
Journal ArticleDOI
Characterization of three non-product materials from a bleached eucalyptus kraft pulp mill, in view of valorising them as a source of cellulose fibres
Mercês Coelho da Silva,O. R. Lopes,Jorge Luiz Colodette,A.O. Porto,Jacques Rieumont,Didier Chaussy,Mohamed Naceur Belgacem,Glaura G. Silva +7 more
TL;DR: In this paper, the structural, thermal, and morphological properties of bleached eucalyptus kraft pulp were analyzed using Fourier transform infrared spectroscopy (FTIR), energy dispersion spectrometry (EDS), X-ray diffraction (XRD), thermogravimetry (TG), temperature modulated differential scanning calorimetry(TMDSC), and scanning electron microscopy (SEM).
Journal ArticleDOI
Cation occupancy sites in synthetic Co-doped magnetites as determined with X-ray absorption (XAS) and Mössbauer spectroscopies
TL;DR: In this paper, it was observed that the continuous increase of Co 2+ is followed by a simultaneous decrease of the Fe 2+ contents, in the spinel structure of cobalt-doped magnetites.
Journal ArticleDOI
Tin(IV) complexes of pyrrolidinedithiocarbamate: synthesis, characterisation and antifungal activity.
Daniele C. Menezes,Flaviana T. Vieira,G.M. de Lima,A.O. Porto,Maria Esperanza Cortés,José D. Ardisson,T.E. Albrecht-Schmitt +6 more
TL;DR: The in vitro antifungal activity of the tin(IV) complexes as well of the ligand was performed on human pathogenic fungi, Candida albicans, and the microorganism presented resistance to the dithiocarbamate ligand and all tin( IV) complexes tested were actives.
Journal ArticleDOI
Synthesis, characterisation and thermal decomposition of tin(IV) dithiocarbamate derivatives – single source precursors for tin sulfide powders
Daniele C. Menezes,G.M. de Lima,A.O. Porto,Claudio Luis Donnici,José D. Ardisson,Antonio C. Doriguetto,Javier Ellena +6 more
TL;DR: In this paper, the reaction of ammonium pyrrolidinedithiocarbamate with SnPh2Cl2 and SnPh3Cl produced in good yield the compounds [S2CN(CH2)4}2{C6H5}2]·-toluene (1) and Sn{S2cn(CH 2)4}{C6h5}3 (2), which were fully characterised by multinuclear NMR [1H,13C{1H} and 119Sn{ 1H}] and 119sn
