Title: Use of small-angle neutron scattering in testing the stability of ferrofluids
Published In: Romanian Reports in Physics, Vol. 57, pp. 261-265
Description: Stability of ferrofluids, colloidal solutions of magnetic particles covered with surfactants, is the main characteristic that determines the possibility to exploit ferrofluids in different industrial and biomedical applications. Small-angle neutron scattering (SANS) can be effectively used to reveal the aggregation and its change with time in ferrofluids under the action of the magnetic field. Despite the fact that in most cases a detailed description of scattering is complicated, one can judge whether a ferrofluid is stable or not by simple analysis of the changes in the mean scattering intensity. The advantages of SANS are that industrial samples can be tested without any additional modifications, as well as that real-time experiments with any magnetic load can be easily performed. Examples for a number of ferrofluids are given.
