X-ray fluorescence spectroscopy from ions at charged vapor/water interfaces
Wei Bu, David Vaknin
X-ray fluorescence spectra from monovalent ions (Cs+) that accumulate from dilute solutions to form an ion-rich layer near a charged Langmuir monolayer are presented. For the salt…
Preferential affinity of calcium ions to charged phosphatidic-acid surface from a mixed calcium/barium solution: X-ray reflectivity and fluorescence studies
Wei Bu, Kevin Flores, Jacob Pleasants +1
X-ray reflectivity and fluorescence near total reflection experiments were performed to examine the affinities of divalent ions ( and ) from aqu…
Extracting the Pair Distribution Function of Liquids and Liquid-Vapor Surfaces by Grazing Incidence X-ray Diffraction Mode
David Vaknin, Wei Bu, Alex Travesset
We show that the structure factor of water can be obtained from X-ray synchrotron experiments at grazing angle of incidence (in reflection mode) by using a liquid surface di…
Micellar Crystals in Solution from Molecular Dynamics Simulations
J. A. Anderson, C. D. Lorenz, A. Travesset
Polymers with both soluble and insoluble blocks typically self-assemble into micelles, aggregates of a finite number of polymers where the soluble blocks shield the insoluble ones…
The many origins of charge inversion in electrolyte solutions: effects of discrete interfacial charges
J. Faraudo, A. Travesset
We show that charge inversion, i.e. interfacial charges attracting counterions in excess of their own nominal charge, is a general effect that takes place in most charged systems n…
Effect of dipolar moments in domain sizes of lipid bilayers and monolayers
Alex Travesset
Lipid domains are found in systems such as multi-component bilayer membranes and single component monolayers at the air-water interface. It was shown by Andelman et al. (Comptes Re…
