Attraction of iodide ions by the free water surface, revealed by simulations with a polarizable force field based on drude oscillators
Archontis, Georgios Z.; Leontidis, Epameinondas; Andreou, Georgia (2005)Recent theoretical and experimental studies have shown that polarizable anions, such as iodide and bromide, preferentially accumulate close to the surface of electrolyte solutions. This finding is in sharp contrast to the ...

Dissecting the stabilization of iodide at the air-water interface into components: A free energy analysis
Archontis, Georgios Z.; Leontidis, Epameinondas (2006)Recent experiments and simulations show that large chaotropic anions favor solvation at the water surface, mainly due to induction interactions dominated by ionic polarizabilities. We compare the solvation free-energy ...

Helix formation by alanine-based peptides in pure water and electrolyte solutions: Insights from molecular dynamics simulations
Ioannou, F.; Leontidis, Epameinondas; Archontis, Georgios Z. (2013)Specific ion effects on oligopeptide conformations in solution are attracting strong research attention, because of their impact on the protein-folding problem and on several important biological-biotechnological applications. ...

Specific interactions of sodium salts with alanine dipeptide and tetrapeptide in water: Insights from molecular dynamics
Ioannou, F.; Archontis, Georgios Z.; Leontidis, Epameinondas (2011)We examine computationally the dipeptide and tetrapeptide of alanine in pure water and solutions of sodium chloride (NaCl) and iodide (NaI), with salt concentrations up to 3 M. Enhanced sampling of the configuration space ...

UV resonance Raman study of TTR(105-115) structural evolution as a function of temperature
Pieridou, Galatia K.; Avgousti-Menelaou, C.; Tamamis, Phanourios; Archontis, Georgios Z.; Hayes, Sophia C. (2011)UV resonance Raman spectroscopy was used to probe the temperature dependence of the conformation of TTR(105-115) in solution. Resonance Raman spectra with excitation at 239.5 nm, show an increase in the absolute resonance ...
