Insights into the electroactive impact of magnetic nanostructures in PVDF composites via small-angle neutron scattering

“…Additionally, the composite SANS data are smooth, without oscillations, meaning that the scattered particles are highly polydisperse. 35…”

Jscatter, a program for evaluation and analysis of experimental data

“…Standard models as Beaucage model, generalized Guinier model, cube, superball, sphere with fuzzy surface, Teubner-Strey model, Gaussian chain, wormlike chain or ring polymers are implemented[23–30]. Standard geometrical models as sphere, ellipsoid of revolution, disc and cylinder are implemented as multishell shapes with unlimited number of shells[31]. This allows shapes with hollow core, core shell particles or gradual changing shells approximated as multiple thin shells.…”

Controlled porosity and pore size of nano-porous gold by thermally assisted chemical dealloying – a SAXS study

“…However, since the two phases cannot be distinguished from each other, this binary phase system was treated as a diluted particle-solution system. 52 The Porod invariant Q was introduced to correlate the scattered beam energy and volume of material V 0 , which was scattered from the main X-ray beam. 53 In in situ dealloying process, the pore formation was regarded as the formation of a 2 nd phase.…”

“…The Porod's law was used to estimate the relative surface area of spherical particles with a smooth surface. 52,54 The Guinier analysis refers to the analysis of the SAXS scattering curve at very small scattering angles (see ESI † for details). The data was plotted by ln I(q) versus q square, as Guinier plot.…”

“…53 The surface area of the material is a direct parameter highlighting the relationship between the pores and ligaments sizes. Although most models are designed for spherical particles with smooth surfaces, 52 the Porod law may be used to evaluate dynamic and relative changes of the surface area across porous materials. 59 The Porod region should be in the region where neither the crystalline structure of the atoms nor the nano-scale geometrical features of the pores scatter.…”
