EFFECT OF THE ORGANIC SOLVENT ON THE INTERFACIAL MICROPOLARITY OF AOT -WATER REVERSE MICELLES
(Sociedad Chilena de Química, 2007)
Estudos microrreológicos da blenda PBT/SAN.
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, 2006-09-22)
This work was motivated by the need of a better understanding of the
microrheological characteristics of polybutylene terephthalate, PBT, polymer
blends, such as the matrix phase PBT and the styrene-acrylonitrile, SAN
copolymer ...
Interfacial behaviour and quantitative analysis of hexadecyl phosphocholine drug at a polarized liquid/liquid interface
(Royal Society of Chemistry, 2022-01)
The interfacial behaviour of the amphiphilic drug hexadecyl phosphocholine (HePC, also called miltefosine) was analysed by cyclic voltammetry applied at the water/1,2-dichloroethane interface. HePC is the only oral drug ...
Detection of chemical alterations at internal walls of microchannel flow cells by nondestructive fluorescence depolarization
(2004)
A recent trend is the production of workable microchannel flow cells (MF cells). The nondestructive methods used to assess their reliability are based mainly on output monitoring and do not evaluate internal chemical ...
Interfacial Tensions of Industrial Fluids from a Molecular-Based Square Gradient Theory
(2016)
This work reports a procedure for predicting the interfacial tension (IFT) of pure fluids. It is based on scaling arguments applied to the influence parameter of the van der Waals theory of inhomogeneous fluids. The molecular ...
Quantum theory of interfacial tension quantitatively predicts spontaneous charging of nonpolar aqueous interfaces
(Elsevier Science, 2015-07)
The spontaneous negative charging of aqueous nonpolar interfaces has eluded quantitative first-principle prediction, possibly because it steadfastly challenges the classical Debye dielectric picture. In this work we show ...
Micellar properties of surface active ionic liquids: A comparison of 1-hexadecyl-3-methylimidazolium chloride with structurally related cationic surfactants
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010)
Ionic liquids, ILs, carrying long-chain alkyl groups are surface active, SAIIs. We investigated the micellar properties of the SAIL 1-hexadecyl-3-methylimidazolium chloride, C(16)MeImCl, and compared the data with ...
Rationally designed peptides with interfacial activity: a molecular dynamics study at the decane-water interface
(Universidad de los AndesMaestría en Ingeniería QuímicaFacultad de IngenieríaDepartamento de Ingeniería Química y de Alimentos, 2021)
Los biosurfactantes son moléculas con actividad interfacial procedentes de fuentes naturales que tienen una creciente demanda mundial, ya que han demostrado potencial para convertirse en sustitutos de varias aplicaciones ...
Adsorption of poly-2-(dimethylamino) ethylmethacrylate-N-alkyl quaternized at the water/chloroform interface
(ELSEVIER SCIENCE BV, 2010-05-04)
The interfacial properties of poly-2-(dimethylamino) ethyl methacrylate-N-alkyl quaternized with octyl,
decyl, dodecyl and tetradecyl bromide are studied from the chloroform to the water/chloroform interface.
In order ...
