One aspect of current interest and great relevance to the fundamental understanding of the
behavior of materials is the role of dimensionality and size on their optical, chemical and
mechanical properties for application in a wide range of devices. In this regard, one-dimensional
systems with nanoscale attributes are being synthesized and studied in great details. For instance,
polymer nanofibers are used as selective gas separation membranes, filters, biomedical materials
(drug carriers and wound dressings), protective clothing, space mirrors, and precursor platforms or
scaffolds for the nanotube/ nanowire synthesis. Owing to the nanoscalar features and peculiar
shapes, one-dimensional systems exhibit novel physical and chemical properties that can be
exploited in optics, catalysis and data storage devices. Thus, they become model systems to study
and correlate the theoretical explanations that are still in progress. Such behavior is almost
nonexistent in the bulk material where the particle size is in the micron level. There is growing
interest in introducing such attributes in nano-sized inorganic materials as well. The most obvious
