Influence of Ionic Liquids on the Aggregation and Pre-aggregation Phenomena of ...
Celia-Silva, Lucas G.; Martins, Rafaela N.; Carvalho, Alfredo J. P.; Ramalho, João P. P.; Morgado, Pedro; Filipe, Eduardo J. M.; Martins, Luís F. G.This work presents a systematic study of asphaltene pre-aggregation phenomena in the absence and in the presence of ionic liquids (ILs) from the family of 1-alkyl-3- methylimidazolium by molecular dynamics simulations. The effects of the alkyl chain length of the cation (studying ILs with alkyl chains between C4 and C10) and of the dimension of the anion (testing chloride and bromide) on the aggregation behavio...
Preaggregation of Asphaltenes in the Presence of Natural Polymers by Molecular ...
Celia-Silva, Lucas G.; Vilela, Patrícia B.; Morgado, Pedro; Lucas, Elisabete F.; Martins, Luís F. G.; Filipe, Eduardo J. M.Cashew nut shell liquid (CNSL), its extract, cardanol, and polycardanol, are known to influence the dispersion behavior of asphaltenes in model solvent mixtures. CNSL and cardanol act as dispersants, while polycardanol can act as both dispersant or flocculant depending on its molecular architecture, concentration, and asphaltene source. In this work, the preaggregation of asphaltenes in model solvents (toluene,...
Supramolecular hydrogel based on a sodium deep eutectic solvent
Florindo, Catarina; Celia-Silva, Lucas G.; Martins, Luís F. G.; Branco, Luís C.; Marrucho, Isabel M.A supramolecular hydrogel based on a metal-containing deep eutectic solvent (DES) is presented here for the first time. The phase diagram of the DES-based hydrogel was drawn and its rheological properties were determined.
