Numerical study on micro-scale extensional viscoelastic flows
(Elsevier B.V., 2020-02-01)
The capillary thinning dynamics can be considered one of the fingerprints of extensionally-dominated viscoelastic flows. Notably, the rheological behavior of complex fluids in extensional flow has been investigated in ...
High-pressure phase equilibrium data for the L-lactic acid plus (propane plus ethanol) and the L-lactic acid plus (carbon dioxide plus ethanol) systems

Síntese de caracterização de nanolubrificante de Licuri de gado
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA MECÂNICA, 2018-01-26)
Vegetable oils are the alternative for the production of biodegradable and nontoxic
lubricants, but the high oxidative rate is a complicating factor. Therefore, this
work proposes the use of transesterified Licuri Gado ...
Novas nanoemulsões aplicadas à recuperação avançada de petróleo em reservatórios carbonáticos
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE PETRÓLEO, 2016-05-23)
Nanoemulsions are systems generally composed by surfactant, aqueous phase and oil phase. These systems may vary according to their composition, size of dispersed droplets, appearance, applications, among others. They have ...
