Inorganic nanoparticles are among the most investigated objects
nowadays, both in fundamental science and in various technical
applications. In this book the physical properties of nanowires
formed by nanoparticles with elongated shape, i.e. rod-like or
wire-like, are described. The transition in the physical properties
is analyzed for nanorods and nanowires consisting of spherical and
rod-like nanoparticles. The physical properties of nanowires and
elongated inorganic nanoparticles are reviewed too. The optical,
electrical, magnetic, mechanical and catalytic properties of
nanowires consisting of semiconductors, noble and various other
metals, metal oxides properties and metal alloys are presented. The
applications of nanorods and nanowires are discussed in the book.
Nanosized magnetic materials have received great attention and
importance during the last decade. Nanomagnetic material is one of
the hottest subjects of present day research activities. The
physical properties of nanosized magnetic materials differ
considerably from that of their bulk counterparts and the magnetic
characteristics of many materials can be tuned by reducing their
size. The objectives of this research work are the synthesis and
studies on the structural and magnetic properties of some selected
transition metal oxides and ferrites in nanocrystalline form. The
research work has been carried out on transition metal ion doped
zinc oxide (ZnO) based diluted magnetic semiconductors (DMSs), some
ferrites (for instance, Zn-ferrite, NiZn-ferrite, maghemite, etc.)
and magnetopolymer nanocomposite systems. The respective
nanocrystalline oxides are synthesized using a simple solution
combustion method and characterized using various techniques. The
results from the studies on different materials are presented in
this thesis, consisting of six chapters. Last but not the least,
several performance parameters have been measured and conditions
for best results have been discussed.
