Phase separation in titanium hydrides studied by small-angle neutron scattering

Phase separation in titanium hydrides studied by small-angle neutron scattering

Various phases of titanium hydrides with differing hydrogen and deuterium content are studied by small-angle neutron scattering. The low temperature metastable x phase produced by quenching under high pressure shows small, but pronounced scattering at liquid nitrogen temperature. At 140 K a very abrupt increase in the scattered intensity is detected, more than one order of magnitude for less th...

Aggregation in ferrofluids studied by Neutron Small Angle Scattering

2014 Neutron Small Angle Scattering has been used to follow processes of particle aggregation in ferrofluids under various conditions of temperature and externally applied magnetic field. Cobalt particles, stabilized in toluene by one of two surfactant materials, showed neutron scattering characteristic of highly aggregated systems. Low temperature quenching in a strong magnetic field caused ph...

Phase Separation in Stainless Steels Stud- ied by Small-angle Neutron Scattering

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...

Structural characterization of ionic gelator studied by dynamic light scattering and small-angle neutron scattering.

Structural characterization of a hydrogel consisting of an oligomeric electrolyte, poly[pyridinium-1,4-diyliminocarbonyl-1,4-phenylenemethylene chloride] (1-Cl) as an ionic gelator was carried out by static and dynamic light scattering (SLS/DLS) and small-angle neutron scattering (SANS) techniques. All the measurements were performed by changing the concentration and temperature. We have succes...
