From Hydrophobic to Hydrophilic: The Structure and Density of the Hexadecane Droplet/Alkanol/Water Interface

Sylvie Roke, Yixing Chen, Kailash Chandra Jena

The molecular structure of the hexadecane droplet/alkanol/water interface has been investigated using vibrational sum frequency scattering and second harmonic scattering. This combination of methods allows us to investigate the interfacial alkyl chain conf ...

Three Dimensional Nano "Langmuir Trough" for Lipid Studies

Sylvie Roke, Yixing Chen, Halil Ibrahim Okur, Kailash Chandra Jena, Cornelis Ulrich Lütgebaucks

A three-dimensional-phospholipid monolayer with tunable molecular structure was created on the surface of oil nanodroplets from a mixture of phospholipids, oil, and water. This simple nanoemulsion preparation technique generates an in situ prepared membran ...

Charge Asymmetry at Aqueous Hydrophobic Interfaces and Hydration Shells

Sylvie Roke, Yixing Chen, Rüdiger Scheu, Kailash Chandra Jena

The solvation of ions in a dielectric continuum is symmetric with respect to the sign of the ionic charge. Yet, many phenomena show indirect evidence that water may have a preference for negative charge: the vast majority of biological membrane interfaces ...

Sum frequency and second harmonic generation from the surface of a liquid microjet

Sylvie Roke, Yixing Chen, Nikolay Smolentsev, Kailash Chandra Jena

The use of a liquid microjet as a possible source of interest for Second Harmonic Generation (SHG) and Sum Frequency Generation (SFG) spectroscopy is examined. We measured non-resonant SHG scattering patterns from the air/water interface of a microjet of p ...

Surface Impurities Are Not Responsible For the Charge on the Oil/Water Interface: A Comment

Sylvie Roke, Rüdiger Scheu, Kailash Chandra Jena

A recent communication by Roger and Cabane[1] on the origin of negative charge on the interface between oil and water states that: "The basic assumption of all previous experimental and theoretical studies has been that these systems have "pristine" oil/wa ...

Comparison of scattering and reflection SFG: a question of phase-matching

Sylvie Roke, Hilton Barbosa De Aguiar, Rüdiger Scheu, Kailash Chandra Jena

We present a comparison between sum frequency scattering (SFS) and reflection mode sum frequency generation (R-SFG). We have used scattering theory to describe both scattering experiments as well as reflection mode experiments. The interfacial vibrational ...
