Development of charged ion exchange resin-polymer ultrafiltration membranes to reduce organic fouling
(Elsevier Science, 2006-07-05)
This work deals with the performance of polymeric membranes charged with an ion exchange resin on the ultrafiltration (UF) of an oily suspension. The membranes were prepared by the phase inversion process from polysulfone ...
Impedance spectroscopy and membrane potential analysis of microfiltration membranes. The influence of surface fractality
(Pergamon-Elsevier Science Ltd, 2018-03)
In this work, the proper charge density of a microfiltration membrane has been determined by using two different methods. Firstly, the ionic transport of a KCl solution has been investigated by simultaneous measurements ...
Vesicles with charged domains
(ELSEVIER SCIENCE BV, 2010)
This work summarizes results obtained on membranes composed of the ternary mixture dioleoylphosphatidylglycerol (DOPG), egg sphingomyelin (eSM) and cholesterol (Chol). The membrane phase state as a function of composition ...
Influence of fixed electric charges on potential profile across the squid axon membrane
(ELSEVIER SCIENCE BV, 2008)
The potential profile for a model of squid axon membrane has been determined for two physiological states: resting and action states. The non-linear Poisson-Boltzmann equation has been solved by considering the volumetric ...
Probing the interaction of oppositely charged gold nanoparticles with DPPG and DPPC Langmuir monolayers as cell membrane models
(Elsevier BVAmsterdam, 2013-04)
The growing use of nanoparticles in a variety of applications calls for detailed studies of their toxicology, which in turn require understanding the interactions between nanoparticles and living cells. Since simulating ...
On the specific filtration mechanism of a mesoporous silica membrane, prepared with non-connecting parallel pores
(2005-04-01)
We report the singular filtration properties of an ultrafiltration membrane made with mesoporous silica that exhibits cylindrical pores aligned mostly normal to the support. This membrane supported on tubular commercial ...

Charged residues are involved in membrane fusion mediated by a hydrophilic peptide located in vesicular stomatitis virus G protein
(Taylor & Francis Ltd, 2006-09-01)
Membrane fusion is an essential step of the internalization process of the enveloped animal viruses. Vesicular stomatitis virus (VSV) infection is mediated by virus spike glycoprotein G, which induces membrane fusion at ...
Lipid-packing perturbation of model membranes by pH-responsive antimicrobial peptides
(2017-10-01)
The indiscriminate use of conventional antibiotics is leading to an increase in the number of resistant bacterial strains, motivating the search for new compounds to overcome this challenging problem. Antimicrobial peptides, ...
