Small angle neutron scattering
Small Angle Neutron Scattering (SANS) is a technique that enables to probe the 3-D structure of materials on a typical size range lying from ∼ 1 nm up to ∼ a few 100 nm, the obtained information being statistically averaged on a sample whose volume is ∼ 1 cm3. This very rich technique enables to make a full structural characterization of a given object of nanometric dimensions (radius of gyrati...
متن کاملMultiple small-angle scattering. A probe for large inhomogeneities
In conventiondl small-angle scattering technique, multiple scattering is amsidered to be of nuisence value and me looks for a correction factor to eliminate its effect. But it is possible to expand the scape of small-angle scattering beyad its ccnventiondl limit if multiple scattering is suitably exploited. This paper intends to illustrate this point. Introduction In traditicmal dl-argle scatte...
متن کاملApplication of small angle X-ray scattering (SAXS) for differentiation between normal and cancerous breast tissues
ABSTRACT Background: Coherent scattering leads to diffraction effects and especially constructive interferences. Theseinterferences carry some information about the molecular structure of the tissue. As breast cancer isthe most widespread cancer in women, this project evaluated the application of small angleX-ray scattering (SAXS) for differentiation between normal and cancerous breast tissues....
متن کاملMultiple magnetic scattering in small-angle neutron scattering of Nd–Fe–B nanocrystalline magnet
We have investigated the influence of multiple scattering on the magnetic small-angle neutron scattering (SANS) from a Nd-Fe-B nanocrystalline magnet. We performed sample-thickness- and neutron-wavelength-dependent SANS measurements, and observed the scattering vector dependence of the multiple magnetic scattering. It is revealed that significant multiple scattering exists in the magnetic scatt...
متن کاملInfluence of multiple well defined conformations on small-angle scattering of proteins in solution.
A common structural motif for many proteins comprises rigid domains connected by a flexible hinge or linker. The flexibility afforded by these domains is important for proper function and such proteins may be able to adopt more than one conformation in solution under equilibrium conditions. Small-angle scattering of proteins in solution samples all conformations that exist in the sampled volume...
