Field-induced self-assembly of iron oxide nanoparticles investigated using small-angle neutron scattering.
The magnetic-field-induced assembly of magnetic nanoparticles (NPs) provides a unique and flexible strategy in the design and fabrication of functional nanostructures and devices. We have investigated the field-induced self-assembly of core-shell iron oxide NPs dispersed in toluene by means of small-angle neutron scattering (SANS). The form factor of the core-shell NPs was characterized and ana...
متن کاملA SANS Experiment to Understand the Nature of Surfactant stabilization in Suspensions of Spherical Colloidal Silica Particles Summer School on Neutron Scattering and Reflectometry from Submicron Structures
Small-angle neutron scattering (SANS) will be used to determine the structures formed by a surfactant additive to a system of spherical silica particles dispersed in water. The measurements will illustrate the advantage of neutron scattering using contrast variation technique. All aspects of the experiment, from the sample preparation and instrument setup through to the data treatment and inter...
متن کاملDirect Measurements of Polymer Brush Conformation Using Small- Angle Neutron Scattering (SANS) from Highly Grafted Iron Oxide Nanoparticles in Homopolymer Melts
Small-angle neutron scattering (SANS) is a sensitive technique that is able to probe the structure of polymer-grafted nanoparticles and free polymer chains. Here, we combine SANS measurements with self-consistent field theory (SCFT) calculations to study the structure of deuterated poly(methyl methacrylate) (dPMMA) nanocomposites containing PMMA-grafted Fe3O4 nanospheres, with a specific emphas...
متن کاملApparatus for Neutron Scattering Measurements on Sheared Fluids
We report on the construction of an apparatus to allow neutron scattering measurements on fluids undergoing shear. The apparatus has been used with the cold neutron small-angle-neutron-scattering (SANS) spectrometer at the NIST research reactor and will be made available to users as a permanent part of the NIST facility.
متن کاملThe Magnetic Correlations and Fluctuations in the Geometrically Frustrated Antiferromagnetic Spinel CdCr2O4: An Experiment Using the SPINS Triple-Axis Spectrometer Summer School on Methods and Applications of Neutron Spectroscopy NIST Center for Neutron Research
We will study the magnetic correlations in the geometrically frustrated antiferromagnetic spinel CdCr2O4 using inelastic neutron scattering. In so doing, we will gain an an understanding of the principles of Triple-Axis Spectroscopy (TAS) and learn how to analyze the TAS data obtained to extract physical information about the system being studied.
