High-pressure phase equilibria of systems carbon dioxide + n-eicosane and propane + n-eicosane
(Elsevier Science, 2009-10)
In this work we investigated the phase equilibrium behavior of the binary asymmetric systems propane (C3) + n-eicosane (C20) and carbon dioxide (CO2) + n-eicosane (C20). We used a variable-volume view cell for obtaining ...
Simulação dinâmica da produção de biossurfactantes pelas bactérias Pseudomonas aeruginosa e Pseudomonas fluorescens utilizando modelo cinético de Monod
(Universidade Federal de São CarlosUFSCarCâmpus São CarlosEngenharia Química - EQ, 2022-09-12)
Surfactants are tensoative compounds with amphipathic characteristics, due to the presence of hydrophilic and hydrophobic structures in the same molecule, which gives them the property of distributing themselves between ...
A solid solution modeling approach somehow analogous to the EoS approach for fluids: Application to equilibria involving fluid phases and solid solutions
(Elsevier Science, 2021-11)
In the present work, a modeling approach applicable over wide ranges of temperature and pressure to the representation of the thermodynamic properties of pure components in solid state is extended to the case of solid ...
Estudo químico e avaliação do potencial farmacológico e herbicida de Maytenus imbricata Mart. ex. Reissek
(Universidade Federal de Minas GeraisUFMG, 2007-03-29)
In this work, it was studied leaves, branches and seeds of Maytenus imbricata, whose chemical constitution and activities pharmacological until this moment had not been reported in literature. From Maytenus imbricata leaves ...
Análisis por dinámica molecular de propiedades tensoactivas de lipopéptidos producidos por Bacillus spp. para su potencial uso en recuperación mejorada de petróleo
(Medellín - Ciencias - Maestría en Ciencias - BiotecnologíaEscuela de biocienciasUniversidad Nacional de Colombia - Sede Medellín, 2019-11-29)
Using surface-active compounds to reduce the interfacial tension between hydrocarbons and water is a mechanism used in Enhanced Oil Recovery. Therefore, substances with a high surfactant activity that cause this reduction ...
