Abstract

CRAIEVICH, A.F.. Synchrotron SAXS Studies of Nanostructured Materials and Colloidal Solutions: A Review. Mat. Res. [online]. 2002, vol.5, n.1, pp. 1-11. ISSN 1980-5373.  http://dx.doi.org/10.1590/S1516-14392002000100002.

Structural characterisations using the SAXS technique in a number of nanoheterogeneous materials and liquid solutions are reviewed. The studied systems are protein (lysozyme)/water solutions, colloidal ZnO particles/water sols, nanoporous NiO-based xerogels, hybrid organic-inorganic siloxane-PEG and PPG nanocomposites and PbTe semiconductor nanocrystals embedded in a glass matrix. These investigations also focus on the transformations of time-varying structures and on structural changes related to variations in temperature and composition. The reviewed investigations aim at explaining the unusual and often interesting properties of nanostructured materials and solutions. Most of the reported studies were carried out using the SAXS beamline at the National Synchrotron Light Laboratory (LNLS), Campinas, Brazil.

Keywords : nanoheterogeneous systems; nanostructured materials; SAXS; synchrotron radiation.
