Preparation of Silver Nanostructures from Bicontinuous Microemulsions

Effect of multiple scattering on SANS spectra from bicontinuous microemulsions.

Small-angle neutron scattering is a powerful tool for investigating the microstructure of self-assembled systems. The domain length, d, and the correlation length, xi, are two measures of bicontinuous microemulsions that are often determined from coherent SANS spectra. Some microemulsions scatter strongly, however, so measured spectra can contain multiple coherent scattering, and neglect of tha...

Mesostructured Polymer Materials Based on Bicontinuous Microemulsions

Bicontinuous Microemulsions under Steady Shear Flow

Dynamic response of microemulsions to shear deformation on the basis of twoorder-parameter time dependent Ginzburg-Landau model is investigated by means of cell dynamical system approach. Time evolution of anisotropic factor and excess shear stress under steady shear flow is studied by changing shear rate and total amount of surfactant. As the surfactant concentration is increased, overshoot pe...

Studying orthogonal self-assembled systems: microstructure of gelled bicontinuous microemulsions.

An orthogonal self-assembled system consists of different structures which coexist independently. Furthermore, the characteristic properties of the respective "base systems", i.e. of the systems which contain only one of the structures, are retained in the orthogonal self-assembled system. We have identified gelled bicontinuous microemulsions as orthogonal self-assembled systems and reported in...

A Novel Method for the Preparation of Silver Halide Nanoparticles from Their Bulk Solid Using Microemulsions

Nanoparticles of silver halides are widely used to study the quantum confinement effects in indirect band gap semiconductors [1]. These particles are typically prepared by carrying out a precipitation reaction in the water pools of w/o microemulsions, or reverse micelles, by mixing two identical microemulsions containing aqueous solutions of AgNO3 and KBr, or other halides [2]. The mixing of tw...
