Current Development & Applications in Nanoparticle Technology-Giuseppe Bonifazi, Full Professor, Dept. ICMA - La Sapienza Università di Roma

Nanotechnology, and more specifically nanoparticles technology, represents one of the most challenging research area of these last years mainly for the wide range of “innovative” applications that can be related to the production and use of particulates, aggregates and structures characterized by dimensions below 1m. Nanometer-sized particles currently attract, in fact, considerable attention because they often present properties which differ from those of the corresponding bulk materials (i.e. nano-particulate fillers of various type and shape utilized in polymers to produce composite materials improve properties while reducing costs) and when utilized to realize nano-structures (i.e. nano-rods, nano-tubes) leads to a variety of properties, in the final manufactured goods, so that to be used in many new and innovative devices (i.e structures, materials, sensing probes, intelligent detectors, etc.).

Preparation & Property Control of Fine Powder in Dry Processes-Dr. Satoshi Akiyama, Manager / Doctor of Philosophy in Engineering Nisshin Seifun Group Inc./Technical Research Center;Carl Ishito, General Manager, AAAmachine, Inc

Numerous techniques have been developed to prepare fine powders in dry processes. There are two major approaches to produce fine powders, namely, breaking-down and building-up approaches. The breaking-down approach is size reduction of large particles. The building-up approach nucleates particles from atom or molecules, which is most commonly used for production of nanometer-sized powders. In this presentation, particle size control techniques of powders with diameter in the range from nanometer to micrometer will be discussed.First, we demonstrate the improvement of grinding and classification processes for fine powders including toners, ceramics and metal using a new classification and grinding technology.Second, we describe the synthesis of nanometer-sized powders by a radio frequency (RF) thermal plasma method.Finally, we discuss properties control including particle size and crystal structure of nanometer-sized powders by the plasma method.
