Percus-Yevick Structure Factors Made Simple
Robert Botet, Sylvie Kwok, Bernard Cabane
Measuring the structure factor, S(q), of a dispersion of particles by Small-Angle X-ray Scattering provides a unique method to investigate the spatial arrangement of colloidal part…
Apollonian Emulsions
Sylvie Kwok, Robert Botet, Abdulwahed Shglabow +1
We have discovered the existence of extremely polydisperse High Internal-Phase-Ratio Emulsions (HIPE) in which the internal-phase droplets, present at 95% volume fraction, remain s…
Packing polydisperse colloids into crystals: when charge-dispersity matters
Guillaume Bareigts, Pree-Cha Kiatkiakajorn, Joaquim Li +5
Monte-Carlo simulations and small-angle x-ray scattering experiments were used to determine the phase diagram of aqueous dispersions of titratable nano-colloids with a moderate siz…
Apollonian Packing in Polydisperse Emulsions
Sylvie Kwok, Robert Botet, Lewis Sharpnack +1
We have discovered the existence of polydisperse High Internal-Phase-Ratio Emulsions (HIPE) in which the internal-phase droplets, present at 95% volume fraction, remain spherical a…
Robustness of the Fractal Regime for the Multiple-Scattering Structure Factor
Nisha Katyal, Robert Botet, Sanjay Puri
In the single-scattering theory of electromagnetic radiation, the {\it fractal regime} is a definite range in the photon momentum-transfer , which is characterized by the scalin…
Hiding in plain view: Colloidal self-assembly from polydisperse populations
Bernard Cabane, Joaquim Li, Franck Artzner +5
We report small-angle x-ray scattering (SAXS) experiments on aqueous dispersions of colloidal silica with a broad monomodal size distribution (polydispersity 18%, size 8 nm). Over…
