The combination of both time-of-flight mode and grazing-incidence small-angle neutron scattering (GISANS) enables the simultaneous performance of several GISANS measurements that differ in wavelength. As a consequence, within one measurement a full set of GISANS patterns related to different scattering vectors, different scattering depths and different resolutions results, which allows the detection of the complex morphology of a defect-rich diblock copolymer film.

Zinc oxide network structures resembling a foam-like morphology are synthesized via a sol-gel route using a structure-directing diblock copolymer with different molecular weights. Grazing-incidence small-angle X-ray scattering has been used to study the variation in porosity and the average pore size of the films, thereby enabling fine tuning of the morphology depending on the final application.

The presence of ordered nanostructures (nearest-neighbour ordering) is reported in self-organized Co nanopillar-like structures separated by Au spacers, attractive for applications in magnetic storage devices. Most interestingly, a strong dependence of the superparamagnetic blocking temperature on the degree of vertical correlation in the stack is found, which indicates a collective behaviour of individual clusters in the nonmagnetic Au matrix.
