Analysing the nanoporous structure of aramid fibres

A novel two-dimensional small-angle X-ray scattering pattern analysis method is presented which extracts parameters characterizing the radius, length and polydispersity of scatterers in heat-treated and precursor poly(p-phenylene terephtalamide) fibres.

Combined in situ small- and wide-angle X-ray scattering studies of TiO₂ nanoparticle annealing to 1023 K

Combined in situ small- and wide-angle X-ray scattering was applied to investigate the dynamical properties of dry oleic acid-capped titanium dioxide nanorods during annealing in an inert gas stream, using a recently developed laboratory setup.
