Caracterização da agregação de asfaltenos por meio de fluorescência molecular [PDF]
, 2006 The tendency of asphaltenes to aggregate and form clusters in solvents was investigated by fluorescence spectroscopy. This was done by evaluating the relative fluorescence quantum yield of asphaltenes diluted at several concentrations in toluene, and by ...

Simulación molecular de la elución de asfaltenos depositados en sílice [PDF]
, 2016 Este trabajo de investigación tiene como objetivo generar un modelo de adsorción y elución de asfaltenos en superficies de sílice utilizando simulación en dinámica molecular. Para el estudio de adsorción, se generaron superficies de óxido de silicio, SiO2, con grupos superficiales siloxano y grupos silanol de tipo vecinal y geminal.
