A SANS Experiment to Understand the Nature of Surfactant stabilization in Suspensions of Spherical Colloidal Silica Particles Summer School on Neutron Scattering and Reflectometry from Submicron Structures

Facile and economic method for preparation of nano-colloidal Silica with controlled size and stability

This study is focused on synthesis of nano-colloidal silica via alkaline water glass solution. Sodium ions of water glass were removed by cation exchanging in a resin column to obtain the silicic acid which was titrated to the solution of sodium silicate. Concentration of the colloidal silica and pH value of the solutions were controlled using different concentrations of alkaline sodium silicat...

Magnetic Structure of Iron Oxide Nanoparticles Using SANS Summer School on Small Angle Neutron Scattering and Neutron Reflectometry NIST Center for Neutron Research

Determination 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...

SHEAR BANDING IN WORMLIKE MICELLAR SOLUTIONS Summer School on Neutron Scattering and Reflectometry

Wormlike micelles are an important class of surfactant micellar architectures that find use in applications ranging from consumer products to energy and nanomaterials. Many wormlike micellar systems exhibit a flow instability known as shear banding, characterized by an inhomogeneous flow field. Although many of the proposed mechanisms and theories for shear banding revolve around fluid microstr...
