Exploring the world of rhamnolipids: A critical review of their production, interfacial properties, and potential application
Eduardo Guzman, Francisco Ortega, Ramon G. Rubio
Rhamnolipids are very promising sugar-based biosurfactants, generally produced by bacteria, with a wide range of properties that can be exploited at an industrial and technological…
A closer physico-chemical look to the Layer-by-Layer electrostatic self-assembly of polyelectrolyte multilayers
Eduardo Guzman, Ramon G. Rubio, Francisco Ortega
The fabrication of polyelectrolyte multilayer films (PEMs) using the Layer-by-Layer (LbL) method is one of the most versatile approaches for manufacturing functional surfaces. This…
Physico-chemical study of polymer mixtures formed by a polycation and a zwitterionic copolymer in aqueous solution and upon adsorption onto negatively charged surfaces
Laura Fernandez-Pena, Eduardo Guzman, Francisco Ortega +5
The adsorption of mixtures of charged polymers onto solid surfaces presents a big interest in different technological and industrial fields, and in particular, in cosmetics. This r…
Study of the Liquid/Vapor Interfacial Properties of Concentrated Polyelectrolyte-Surfactant Mixtures Using Surface Tensiometry and Neutron Reflectometry: Equilibrium, Adsorption Kinetics and Dilational Rheology
Sara Llamas, Eduardo Guzman, Andrew Akanno +5
The adsorption of mixtures of poly(diallyldimethylammonium chloride) (PDADMAC) and sodium N-lauroyl-N-methyltaurate (SLMT) at the water / vapor interface has been studied using dro…
Equilibration of a Polycation-Anionic Surfactant Mixture at the Water-Vapor Interface
Andrew Akanno, Eduardo Guzman, Laura Fernandez-Pena +3
The adsorption of concentrated polydiallyldimethylammonium chloride, PDADMAC-sodium lauryl ether sulfate (SLES) mixtures at the water-vapor interface has been studied by different…
Effect of molecular structure of eco-friendly glycolipid biosurfactants on the adsorption of hair-care conditioning polymers
Laura Fernandez-Pena, Eduardo Guzman, Fabien Leonforte +6
Pseudo-binary mixtures of different glycolipids, four different rhamnolipids (RL) and an alkyl polyglucoside (APG), with poly(diallyl-dimethylammonium chloride) (PDADMAC) have been…
