Nanostructured materials spectroscopy

Mossbauer spectroscopy has been extensively used for studies of nanostructured materials and several reviews on magnetic nanoparticles have been published, see e.g. [6-8, 46 8]. The magnetic properties of nanoparticles may differ from those of bulk materials for several reasons. The most dramatic effect of a small particle size is that the magnetization direction is not stable at finite temperatures, but fluctuates.

X-ray diffraction technique is a non-destructive analytical technique that reveals information about crystallographic structure, chemical composition and physical properties of nanostructured materials. UV/Vis spectroscopy is routinely used in the quantitative determination of films of nanostructured metal oxides. The size, shape (nanocomb and nanorods etc,) and arrangement of the nanoparticles can be observed through transmission electron microscope (TEM) studies. Surface morphology of nanostructured metal oxides can be observed in atomic force microscopy (AFM) and scanning electron microscopy (SEM) studies. 

Direct observations of polyethylene embedded in the fiiUy aromatic channels of TPP nanostructured materials was provided by NMR spectroscopy in one- and two-dimensions (Fig. 14) [42]. 

The volume is organized into three sections, each of which addresses fundamental and practical realization of the production of nanostructured materials. The first section deals with the preparation, characterization, and transport properties of this unique class of materials. Structural and chemical heterogeneity are the result of preparation protocols, and various spectroscopies can be used to characterize these properties. Transport of adsorbates is affected by both intraparticle and interparticle resistance, which can greatly influence applications in practical processes. Each of these topics is represented as a case study that is general enough in scope that cautious application of the reported results can be extended to other systems of technological importance.

This outline of the principal characterization techniques for nanocomposite materials and nanosized metal fillers is far from being complete. Advances in Raman spectroscopy, energy dispersive spectroscopy, infrared spectroscopy, and many other techniques are of considerable importance as well. In fact, the success that nanostructured materials are having in the last few years is strictly related to the advanced characterization techniques which are available today.
