Anisotropic light scattering in water-alcohol mixtures
نویسندگان
چکیده
We have studied the depolarized Rayleigh-Wing light scattering of aqueous solutions of 2-butoxyethanol (C&) as a function of the temperature and concentration. The measured spectra give information on the rotational dynamics of water molecules. Their analysis confirm the amphiphilic character of the ethoxylated alcohol molecules that originates micellar structures. In addition, the water dynamics shows, in agreement with recent small angle neutron scattering measurements, the simultaneous presence of micelles and concentration fluctuations. This latters are dominant at high temperatures when one approaches the demixtion curve.

The impact of the structuring of hydrotropes in water on the mesoscale solubilisation of a third hydrophobic component.
In the present contribution, the pre-structuring of binary mixtures of hydrotropes and H2O is linked to the solubilisation of poorly water miscible compounds. We have chosen a series of short-chain alcohols as hydrotropes and benzyl alcohol, limonene and a hydrophobic azo-dye (Disperse Red 13) as organic compounds to be dissolved. A very weak pre-structuring is found for ethanol/H2O and 2-propa...
متن کاملDetermination of the size distribution of monodesperse and bidisperse mixtures of spherical particles in the nanometer and submicron size range by applying cumulant analysis and contin algorithm in dynamic light scattering
Determination of particle size is one of the major needs in the industry and biotechnology. Dynamic light scattering (DLS) is a widely used technique for determining size distribution of spherical particle in nanometer and submicron size range. In this method, there are different algorithms for determining the size and size distribution of particles, which are selected according to the required...
متن کاملStructural effects of the solvent composition in colloidal liquids
This paper is concerned with the microstructure observed in colloidal dispersions of charged polymeric particles and their interaction potential at very low ionic strength. Both aspects are probed with the aid of new experimental data for nonaqueous media. The structure factor of ordered dispersions ~with methanol–water and ethanol–water solvent mixtures! was determined using static light scatt...
متن کاملStructure and dynamics of poly(vinyl alcohol) gels in mixtures of dimethyl sulfoxide and water
We reviewed our structure studies on poly(vinyl alcohol) (PVA) gels formed in the mixtures of dimethyl sulfoxide (DMSO) and water using various scattering methods, including wide-, smalland ultra-small-angle neutron scattering and light scattering. These studies revealed the hierarchic structure of PVA gels formed in DMSO/water (60/40 v/v) in a very wide spatial scale from 1 Å to several microm...

In the present research, the D-(+)-Glucose–confined water nanodroplets with mean size in the range of 6-11 nm were synthesized at D-(+)-Glucose different concentrations by AOT reverse micelles (RMs) method as a function of mass fraction of droplet (MFD) at the constant water-to-surfactant molar ratio ( W=40). The dynamic light scattering of the nano-sized water droplets containing the D-(+)-Glu...
