| | 3D structure of nano-scale materials by total x-ray scattering | | Authors: | V. Petkov | | Affilation: | Central Michigan University, US | | Pages: | 5 - 8 | | Keywords: | total x-ray scattering, 3D atomic-scale structure | | Abstract: | Knowledge about the three-dimensional (3D) structure, including the type and positions of atomic/molecular units in space, is an important prerequisite to understanding, predicting and improving properties of materials. With common materials it is routinely obtained by Bragg x-ray diffraction. With materials structured at the nano-scale, however, traditional x-ray crystallography fails because of the very limited length of structural coherence they show. We will present a non-traditional approach involving total (Bragg and diffuse) x-ray scattering and atomic Pair Distribution Function analysis for determining the 3D structure of nano-scale materials with atomic resolution. The great potential of the approach will be illustrated with examples from recent studies on nanoparticles [1], nanocomposites [2], nanotubes [3], nanoceramics [4], polymeric templates [5] and others. 1.
