Porosity determination in doped graphites using small-angle neutron scattering measurements

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...

Shear-Induced Coalescence in Two-Phase Polymeric Systems. I. Determination from Small-Angle Neutron Scattering Measurements

The attainment of improved physical properties through the blending of immiscible polymers is a well-established practice.1>2 The properties of such multiphase polymer systems reflect to a large extent the nature of the blend morphology, which in turn is influenced by the properties of the constituent materials as well as by the blending conditions employed. In particular, the dispersed-particl...

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...
