Effects of hofmeister anions on DPPC langmuir monolayers at the air-water interface
(2004)In this work we investigated the effect of sodium salts of different monovalent anions belonging to the Hofmeister series on Langmuir monolayers of DPPC (1,2-dipalmitoyl phosphatidylcholine). The salts used were NaCl, NaBr, ...

Effects of sodium salts of lyotropic anions on low-temperature, ordered lipid monolayers
(2012)Electrolytes are known to impart considerable disorder to lipid assemblies, including monolayers at the air-water interface, bilayers, and vesicles. In the present work, we have investigated the disordering effect of sodium ...

Influence of nanoreactor environment and substrate location on the activity of horseradish peroxidase in olive oil based water-in-oil microemulsions
(2011)Oxidative enzymatic reactions using horseradish peroxidase (HRP) were carried out in water-in-oil (w/o) microemulsions composed of olive oil/lecithin/1-propanol/water, a model biomimetic system. The substrates used (gallic ...

Investigations of the Hofmeister series and other specific ion effects using lipid model systems
(2017)From the ion point-of-view specific ion effects (SIE) arise as an interplay of ionic size and shape and charge distribution. However in aqueous systems SIE invariably involve water, and at surfaces they involve both ...

Liquid expanded monolayers of lipids as model systems to understand the anionic hofmeister series: 1. A tale of models
(2009)In this work, we use Langmuir monolayers of dipalmitoyl phosphatidylcholine (DPPC) as model systems to enhance the understanding of specific anion effects in physicochemical and biological systems. The 298 K isotherms ...

Liquid expanded monolayers of lipids as model systems to understand the anionic hofmeister series: 2. Ion partitioning is mostly a matter of size
(2009)In the preceding paper of this series [Leontidis, E.

Monolayer properties of surface-active metalorganic complexes with a tunable headgroup
(2008)Surface-active metalorganic complexes can be used to construct organic thin films with excellent electronic and catalytic properties. We have recently introduced a new versatile surface-active ligand, which can efficiently ...

Monolayers, bilayers and micelles of zwitterionic lipids as model systems for the study of specific anion effects
(2007)This work is a review of the effect of different monovalent anions (belonging to the Hofmeister series) on a single model amphiphile, phosphatidylcholine molecules in contact with water, in three different geometries, ...

Tunable excitons in gated graphene systems
(SPIE, 2017)We develop a microscopic theory of a strong electromagnetic radiation interaction with bilayer graphene where an energy gap is opened by a static electric field perpendicular to graphene planes. We show that an adiabatic ...

Ultrafast time-resolved spectroscopy of Si nanocrystals embedded in SiO2 matrix
(2009)In this work, we present a comprehensive study of ultrafast transient photoinduced absorption of silicon nanocrystals (NCs) embedded in SiO2 matrix. The samples under investigation are single monolayers of Si-NCs embedded ...

Vibrational sum frequency generation spectroscopic investigation of the interaction of thiocyanate ions with zwitterionic phospholipid monolayers at the air-water interface
(2009)Thiocyanate (SCN-) is a highly chaotropic anion of considerable biological significance, which interacts quite strongly with lipid interfaces. In most cases it is not exactly known if this interaction involves direct binding ...
