Zeta potential and doping in polyaniline dispersions
(Oficyna Wydawnicza Politechniki Wroclawskiej, 2003-01-01)
Polyaniline (PAni) has been classified as an intractable polymer, particularly in its conducting form, the emeraldine salt (ES). Therefore one can consider the mixture of water and PAni as a suspension. The conducting form ...
Influence of membrane-solution interface on the selectivity of SnO2 ultrafiltration membranes
(Elsevier B.V., 2001-03-01)
SnO2 supported membranes, presenting 3.0 nm average pore size, have been produced by sol casting on alumina tubular substrate using aqueous colloidal suspensions prepared by sol-gel route. The selectivity and flux throughout ...
Preparation and characterization of PAni-PMMA dispersions
(Taylor & Francis Inc, 2005-01-01)
Blends of polyaniline (PAni) and poly(methyl methacrylate) (PMMA) have been produced using core-shell particle synthesis, which is advantageous because it allows changing surface-related properties of PMMA with relatively ...
Synthesis and evaluation of diethylethylamine-chitosan for gene delivery: Composition effects on the in vitro transfection efficiency
(2013-02-08)
Chitosan has been indicated as a safe and promising polycation vector for gene delivery. However its low transfection efficiency has been a challenging obstacle for its application. To address this limitation, we synthesized ...
A New Framework to Quantify the Wetting Behaviour of Carbonate Rock Surfaces Based on the Relationship between Zeta Potential and Contact Angle
(2020-02-23)
This study introduces a new framework to quantify the wettability of powdered carbonate rock from existing correlations between zeta potential and contact angle. The new framework has the potential to be faster and cheaper ...
Interactions of mast cell degranulating peptides with model membranes: A comparative biophysical study
(Elsevier B.V., 2009-06-01)
In the last decade, there has been renewed interest in biologically active peptides in fields like allergy, autoimmume diseases and antibiotic therapy. Mast cell degranulating peptides mimic G-protein receptors, showing ...
Physical factors affecting plasmid DNA compaction in stearylamine-containing nanoemulsions intended for gene delivery
(2012-06-13)
Cationic lipids have been used in the development of non-viral gene delivery systems as lipoplexes. Stearylamine, a cationic lipid that presents a primary amine group when in solution, is able to compact genetic material ...
