Small-angle neutron scattering study of nanophase zirconia in a reverse micelle synthesis

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...

Micellar structure and inter-micelle interactions in micellar solutions: Results of small angle neutron scattering studies

Micelles are aggregates of surfactant molecules suspended in water. The structure (shape and size) of a micelle depends both on the architecture of the constituent surfactant molecule and the solution conditions such as temperature, presence of impurities, etc. The inter-particle interaction between micelles also depends on several different parameters. It is of interest to study the structure ...

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...

Use of small-angle neutron scattering to study tubulin polymers.

Small-angle neutron scattering has been used to examine taxol-stabilized microtubules and other tubulin samples in both H(2)O and D(2)O buffers. Measurements were made at pH/pD values between 6.0 and 7.8, and observed scattered intensities, I(Q), have been interpreted in terms of multicomponent models of microtubules and related tubulin polymers. A semiquantitative curve fitting procedure has b...
