Book Description
This book presents a complete and updated overview of Flame Spray process, from its History to the Apparatus necessary for the synthesis of nanostructures. It addresses not only the materials produced by this technique, but also their properties, such as crystallinity and crystallite size, specific surface area, particle size and morphology. Also, the principles of nanoparticle formation are described. It is a useful read to all those interested in low cost synthesis of nanostructured powders and coatings.

Book Description
This dissertation focuses on the synthesis of nanomaterials by both solution phase and gas phase methods. By the solution phase method, we demonstrate the synthesis of Au/CdS binary hybrid nanoparticles and the Au-induced growth of CdS nanorods. At higher reaction temperature, extremely uniform CdS nanorods were obtained. The size of the Au seed nanoparticles has an important influence on the length and diameter of the nanorods. In addition, preparation of peanut-like FePt-CdS hybrid nanoparticles by spontaneous epitaxial nucleation and growth of CdS onto FePt-seed nanoparticles in high-temperature organic solution is reported. The FePt-CdS hybrid nanoparticles reported here are an example of a bifunctional nanomaterial that combines size-dependent magnetic and optical properties. In the gas phase method, a spray pyrolysis aerosol synthesis method was used to produce tellurium dioxide nanoparticles and zinc sulfide nanoparticles. Tellurite glasses (amorphous TeO 2 based materials) have two useful optical properties, high refractive index and high optical nonlinearity, that make them attractive for a range of applications. In the work presented here, TeO 2 nanoparticles were prepared by spray pyrolysis of an aqueous solution of telluric acid, Te(OH) 6 . This laboratory-scale process is capable of producing up to 80 mg/hr of amorphous TeO 2 -nanoparticles with primary particle diameters from 10 to 40 nm, and allows their synthesis in significant quantities from an inexpensive and environmentally friendly precursor. Furthermore, both Er 3+ doped and Er 3+ and Yb 3+ co-doped tellurium dioxide nanoparticles were synthesized by spray pyrolysis of an aqueous mixture of telluric acid with erbium/ytterbium salts, which exhibit the infrared to green visible upconversion phenomena. ZnS nanoparticles (NPs) were prepared by spray pyrolysis using zinc diethyldithiocarbamate as a single-source precursor. The home-built scanning mobility particle spectrometer (SMPS) is a useful tool for online measurement of the as-produced nanoparticle size distribution in the gas phase. These SMPS results show clearly the transition of precursor aerosol from liquid to vapor phase and that nanoparticle production in the reactor occurs via gas-to-particle conversion. Applicable characterization methods were employed to characterize and to investigate the optical properties of the various materials described in this dissertation.

Book Description
A critical, up to date, tutorial review and discussion of the science and technology of nanostructured metallic and ceramic materials. The focus is on the synthesis and processing of nanoparticles, the assembly and stability of nanostructures, characterization and properties, and applications. There is a growing interest in the processing of nanoparticles into consolidated bulk materials and coatings. The metastability of nanoparticles may lead to undesirable grain growth during thermally assisted consolidation or other processing routes, and the retention of nanostructures in a processed part or component continues to attract a great deal of attention. Current activity is concentrating on the deposition of nanostructured coatings using established thermal spray technology and wet chemistry methods. Naturally existing or artificially synthesized templates with unique structures and morphologies have been used to fabricate nanostructured materials with the same structural and morphological characteristics as the templates. Recent advances in characterization techniques have provided information on the structure, the surface and bulk chemistry of nanoparticles, and the structures and chemistry of exposed and buried surfaces of coatings. Contributors are drawn from Canada, France, UK, USA, Belarus, Russia and Ukraine.

Book Description
Due to a great chemical similarity with the biological calcified tissues, many calcium orthophosphates possess remarkable biocompatibility and bioactivity. Materials scientists use this property extensively to construct artificial bone grafts that are either entirely made of or only surface-coated with the biologically relevant calcium orthophospha

Book Description
The Polish Complex takes place on Christmas Eve, from early morning until late in the evening, as a line of people (including the narrator, whose name is Konwicki) stand and wait in front of a jewelry store in Warsaw. Through the narrator we are told of what happens among those standing in line outside this store, what happens as the narrator's mind thinks and rants about the current state of Poland, and what happens as he imagines the failed Polish rebellion of 1863. The novel's form allows Konwicki (both character and author) to roam around and through Poland's past and present, and to range freely through whatever comes to his attention. By turns comic, lyrical, despairing, and liberating, The Polish Complex stands as one of the most important novels to have come out of Poland since World War II.

Book Description
Nanoparticle technology, which handles the preparation, processing, application and characterisation of nanoparticles, is a new and revolutionary technology. It becomes the core of nanotechnology as an extension of the conventional Fine Particle / Powder Technology. Nanoparticle technology plays an important role in the implementation of nanotechnology in many engineering and industrial fields including electronic devices, advanced ceramics, new batteries, engineered catalysts, functional paint and ink, Drug Delivery System, biotechnology, etc.; and makes use of the unique properties of the nanoparticles which are completely different from those of the bulk materials. This new handbook is the first to explain complete aspects of nanoparticles with many application examples showing their advantages and advanced development. There are handbooks which briefly mention the nanosized particles or their related applications, but no handbook describing the complete aspects of nanoparticles has been published so far. The handbook elucidates of the basic properties of nanoparticles and various nanostructural materials with their characterisation methods in the first part. It also introduces more than 40 examples of practical and potential uses of nanoparticles in the later part dealing with applications. It is intended to give readers a clear picture of nanoparticles as well as new ideas or hints on their applications to create new materials or to improve the performance of the advanced functional materials developed with the nanoparticles. * Introduces all aspects of nanoparticle technology, from the fundamentals to applications. * Includes basic information on the preparation through to the characterization of nanoparticles from various viewpoints * Includes information on nanostructures, which play an important role in practical applications.
