Spacing distributions were measured in colloidal solutions containing TiO2 scatterers and a laser dye .
Recent developments in the theory of multimode random lasers
Spectra with almost equally spaced lasing peaks were obtained in TiO2 colloidal solutions with strong reabsorption outside of the pumped volume .
Recent developments in the theory of multimode random lasers
The difference between lasing peaks and spontaneous-emission spikes in TiO2 colloidal solutions with weak reabsorption (see above) emerges also in the emission intensity statistics.

Test 1: We have performed in situ measures of effective forces in typical colloidal conﬁgurations, from the solution of a multi-center Poisson-Boltzmann theory (with Nc = 4000 colloids).
Testing the relevance of effective interaction potentials between highly charged colloids in suspension
Deriving now Zeff by comparing the solution of the PB equation with the known far-ﬁeld expression for the electrostatic potential φ(r), one can again compute a colloidal background charge Zback which differs from the previous one.
Testing the relevance of effective interaction potentials between highly charged colloids in suspension
Lastly, we mention that the electric ﬁeld drops off rapidly in the vicinity of highly charged ob jects in solutions, and that the resulting ﬁeld gradients could lead to local phaseseparation around charged colloids.
Phase-separation in ion-containing mixtures in electric fields
For a colloid of size R = 1 µm in ion-free solution of dielectric constant ε = 10ε0 , the ﬁeld near the colloid’s surface is E = Q/(εR2 ), and the charge Q for separation is of the order of 1000 e.

We can look at the situation of colloids from the very different perspective of a single particle falling through solution.
The unreasonable effectiveness of equilibrium-like theory for interpreting non-equilibrium experiments
In polymer solutions the reason for this depletion force originates from the presence of depletion zones near the conﬁning walls or mesoscopic particles due to the additional amount of entropic energy for polymers conﬁned within the slit or between colloidal particles.
Polymer chains in confined geometries: Massive field theory approach
In the case of addition of the polymer chains to the solvent of colloidal solution effective attraction between particles leads to ﬂocculation3 .
Polymer chains in confined geometries: Massive field theory approach
But, such approach does not give possibility to describe correctly behavior of small colloidal particles in polymer solution and for the case of colloidal particle of the big size the difference between theoretical predictions and experimental data are bigger than 10%.

The stability of the solitary waves solutions was considered numerically in one and two spatial dimensions. considered a power series for the compressibility of the colloid particles with the coeﬃcients of the series found by using the Debye-Huckel model for the particle interactions.
