RVK: RVK: UQ 8420Online resources: Summary: Materials with nanometer size particles exhibit unique chemical and physical properties. In particular, nanocomposite materials, composed of nanometric metal and metal oxide particles embedded in vitreous matrices, present a variety of interesting magnetic, electric and catalytic properties, that are strongly size-dependent. Among the different preparation methods which can be used to obtain this kind of materials, the sol-gel process is particularly interesting because it is affected by several parameters which allow a versatile control of the structural, textural and chemical properties of the final products. The present volume focusses on the preparation of metal-silica and metal oxide-silica (Me=Ni, Fe, Zn) nanocomposites by the sol-gel method and the characterization of their structural and magnetic properties. Describes recent research in nanocomposites, focusing on the preparation of metal-silica and metal oxide-silica nanocomposites by the sol-gel method and characterization of their structural and magnetic properties. Reports on operational conditions which produce composite powders with nanometric particles, and checks results of preparations using X-ray diffraction, transmission electron microscopy, and Mössbauer spectroscopy. Also reports on results using IR, MASNMR, and EXAFS spectroscopic techniques, and details preparations which give rise to improved results. The authors are affiliated with the department of chemical science at Cagliari University, Italy.PPN: PPN: 1727621514Package identifier: Produktsigel: ZDB-1-SNTA
