Although there has long, there are still scientists who are not aware of the possibilities offered by SANS, especially with the advent of new precision tools and sources of so-called "Cold Neutron." For those who want more information on NIST offers some: tutorials technique .

The technique of neutron scattering small angle, called SANS Small Angle Neutron Scattering to study in great detail the microstructure of different materials. Being able to see what happens in materials at scales ranging from microns to nanometers, can improve the physical properties of materials such as polymers and suspensions of particles in fluids.

Two recent examples provide an idea of the potential of this technique.

In the latest issue of the Journal of Rheology (1) the technique is used to reveal how colloidal particles are oriented in different ways at different cutting speeds in a cell type couette . The particles have ordered structures at low and high cutting speeds. At intermediate values are lost long-range order.

In a study published in Science (2) is used to determine how to form the "shiskebabs, a key structure in the crystallization of polymers that affects the surface quality of a semi-crystalline polymer. This allows control properties such as hardness, impact resistance, reflectivity and adhesion.
