Pinto, Fernanda E.; Fonseca, Victor R.; Souza, Lindamara M.; Terra, Luciana A.; Subramanian, Sreedhar; Simon, Sebastien Charles; Sjøblom, Johan; Pereira, Thieres M.; Lacerda, Valdemar Jr.; Romão, Wanderson (Peer reviewed; Journal article, 2022)

Negative ion-mode electrospray (ESI(-)) technique coupled to Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) provides ionization of polar constituents with ultra-high resolution and mass accuracy. ...
Asphaltenes subfractions extracted from Brazilian vacuum residue: Chemical characterization and stabilization of model water-in-oil (W/O) emulsions

Zorzenao, Priscila C.S.; Mariath, Rubia M.; Pinto, Fernanda E.; Tose, Lilian V.; Romão, Wanderson; Santos, Alexandre F.; Scheer, Agnes P.; Simon, Sebastien Charles; Sjøblom, Johan; Yamamoto, Carlos I. (Journal article, 2018)

Asphaltenes were obtained from a Brazilian vacuum residue (VR) by precipitation with different ratios of n-heptane/VR to give three asphaltene subfractions. The behavior of these different subfractions in relation to the ...
