On the stability and necessary electrophoretic mobility of bare oil nanodroplets in water

Sylvie Roke, Hilton Barbosa De Aguiar, Saranya Pullanchery Sankara Narayanan, Halil Ibrahim Okur, Sergey Kulik

Hydrophobic oil droplets, particles, and air bubbles can be dispersed in water as kinetically stabilized dispersions. It has been established since the 19th century that such objects harbor a negative electrostatic potential roughly twice larger than the t ...

The Presence of Ultralow Densities of Nanocrystallites in Amorphous Poly(lactic acid) Microspheres

Sylvie Roke, Hilton Barbosa De Aguiar

Ultralow densities of crystalline nanospheres have been detected in amorphous polymer microspheres by utilizing the unique sensitivity of second-order nonlinear optical techniques to anisotropy. Vibrational sum frequency scattering (SFS) and X-ray diffract ...

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

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

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 ...
