Scaling of kinetically growing clusters

M Kolb, R Botet, R Jullien - Physical Review Letters, 1983 - APS
A model describing the process of cluster growth by aggregation of clusters is introduced
and investigated with the Monte Carlo method. It is found that the clusters are scale invariant. …

Enhanced Raman scattering by fractal clusters: Scale-invariant theory

MI Stockman, VM Shalaev, M Moskovits, R Botet… - Physical Review B, 1992 - APS
A scale-invariant theory of Raman scattering of light by fractal clusters is developed. The
enhancement factor G RS of Raman scattering is shown to scale in terms of a properly chosen …

Aggregation of magnetic microspheres: experiments and simulations

G Helgesen, AT Skjeltorp, PM Mors, R Botet, R Jullien - Physical review letters, 1988 - APS
Uniformly sized microspheres interacting via long-range magnetic dipolar forces are used to
study diffusion-limited cluster aggregation in a plane. The results show that it is possible to …

Mean-field approximation of Mie scattering by fractal aggregates of identical spheres

R Botet, P Rannou, M Cabane - Applied optics, 1997 - opg.optica.org
We apply the recent exact theory of multiple electromagnetic scattering by sphere
aggregates to statistically isotropic finite fractal clusters of identical spheres. In the mean-field …

Hierarchical model for irreversible kinetic cluster formation

R Botet, R Jullien, M Kolb - Journal of Physics A: Mathematical …, 1984 - iopscience.iop.org
A model is proposed to describe the growth of clusters by a mechanism of irreversible
clustering of clusters. The fractal exponent is extracted by means of numerical simulations on …

Hiding in plain view: colloidal self-assembly from polydisperse populations

B Cabane, J Li, F Artzner, R Botet, C Labbez… - Physical review …, 2016 - APS
We report small-angle x-ray scattering experiments on aqueous dispersions of colloidal silica
with a broad monomodal size distribution (polydispersity, 14%; size, 8 nm). Over a range of …

A new interpretation of scattered light measurements at Titan's limb

P Rannou, M Cabane, R Botet… - Journal of Geophysical …, 1997 - Wiley Online Library
Images of Titan, taken by Voyager 2 at phase angles Φ=140 and Φ=155 have provided radial
intensity profiles at the bright and dark limbs, which provide information on the vertical and …

The" ouzo effect", recent developments and application to therapeutic drug carrying

R Botet - Journal of Physics: Conference Series, 2012 - iopscience.iop.org
This short review is about the spontaneous emulsification effect, aka the" ouzo effect". Under
certain conditions, pouring a mixture ol a totally water-miscible solvent and a hydrophobic …

Structural anisotropy of directionally dried colloids

…, L Pauchard, F Giorgiutti-Dauphiné, R Botet… - Europhysics …, 2014 - iopscience.iop.org
Aqueous colloidal dispersions of silica particles become anisotropic when they are dried
through evaporation. This anisotropy is generated by a uniaxial strain of the liquid dispersions …

How do interactions control droplet size during nanoprecipitation?

R Botet, K Roger - Current Opinion in Colloid & Interface Science, 2016 - Elsevier
Nanoprecipitation provides colloidal dispersions through successive recombination events
between nanometric objects. In the present article, we explain why the nanoprecipitation …
