Using small angle neutron scattering to explore porosity, connectivity and accessibility, towards optimised hierarchical solid acid catalysts

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...

MnO 3 by small angle neutron scattering

Neutron small angle scattering of hemoglobin.

Neutron small angle scattering experiments were performed on human hemoglobin in various mixtures of Hz0 and DzO. It was possible to observe the inter-particle effect without corrections for resolution and to verify the first minimum and the secondary maximum in accordance with the theoretical scattering curve. The accuracy in determining the radius of gyration has been improved over that deter...

Small-angle neutron scattering to detect rafts and lipid domains.

The detection and characterization of lateral heterogeneities or domains in lipid mixtures has attracted considerable interest, because of the roles that such domains may play in biological function. Studies on both model and cell membranes demonstrate that domains can be formed over a wide range of length scales, as small as nanometers in diameter up to microns. However, although the size and ...
