Book Description
The present work deals with effect of particle size, concentration of nickel, and calcination temperature on the enhancement of tetragonal zirconia nanopowders. Nanocrystalline tetragonal zirconia is commercially very significant material which finds extensive use as an anode material in SOFC, as a catalyst oxygen sensor and structural material. In the present project work, nanocrystalline zirconia powders were prepared by co-precipitation technique. This technique is very helpful for the promotion of the stabilization of t-phase of ZrO2 at nano level at moderate temperature which is one of the primary objectives of this project. Here the main objective is to stabilize the t-ZrO2 through precipitation route using NH4OH. The concentration of nickel-salt plays an important role for the enhancement of stabilized tetragonal phase at moderate temperature. From XRD results it has been concluded that stabilization of t-ZrO2 was better for 20 mol% nickel-salt concentration as compared with 40 mol% Ni-salt at the same temperature.

Book Description
The development of small and smallest particle is one of today's key features in modern science. The goal is to form materials with improved properties than their "classical" ancestors with just a fractional amount of raw material. However, the characterization of these particles is as important as their way of preparation. Different techniques with their origins in physics, inorganic, organic and physical chemistry have to be combined to reveal the secrets of this important field of science. This book gives a short overview of theoretical basics and synthesis methods to form and characterize gold and zirconia nanoparticles. Phenomenon like plasmon resonance self-assembly of surfactants and the different structures of ZnO2 are explained. Furthermore, analytical tools, like small angle X-ray scattering, X-ray powder diffraction and scanning electron microscopy are introduced. In addition, details on the synthesis of gold and zirconia nanoparticles are presented and are examined by the mentioned analytical and calorimetric methods.
