Abstract

The atomic Pair Distribution Function (PDF) analysis and high-energy x-ray diffraction are introduced as a tool for determining the three-dimensional structure of nanocrystalline materials. The great potential of this experimental approach is demonstrated with results from successful studies on (Polyaniline)_xV₂O₅nH₂O nanocomposites and dendrimer stabilized gold nanoparticles. We find that (Polyaniline)_xV₂O₅nH₂O has a lamellar-type structure wherein polymeric chains are sandwiched between double layers of V-O₆ octahedra. Gold nanoparticles possess a distorted face centered cubic-type structure with the degree of distortion increasing with the decrease in particle's size.
