Hiroshima University Research Center
for Nanoparticle Synthesis and Its Application
OBJECTIVES
The objective of this Center has been to establish a platform for developing the synthesis and functionalization technologies of nanoparticles, which is important for producing nanostructures and expressing nano-functions. In this manner, existing materials imparted a nanostructure to produce a new function such as quantum size effect. Through the expression of chemical, electronic, optical and mechanical properties that are totally different from the same material in bulk form, it is possible to create a new system of materials technologies that can be used in a wide range of application fields, including chemistry, electronics, electrical engineering, optics, catalysts, ceramics, and mechanics. In this project, the following research fields will be carried out; (1)research and development of high-rate synthesis technology for single-nanometer sized particles (nanoparticles); (2)research and development of surface modification and thin film preparation technology for nanoparticles; (3)preparation and performance evaluation of functional elements utilizing nanoparticles, and (4)systematization of related technologies.
In the synthesis of nanoparticles, liquid phase synthesis (e.g., micro-emulsion, reverse micelle process, hot-soap process, spray pyrolysis) and gas-phase synthesis will be conducted to elucidate the particular features of the various methods by investigating particle diameter, particle size distribution, morphology/shape, surface characteristics, compatibility with materials and their link with the surface modification techniques.
Related to the techniques for synthesizing nanoparticles, methods are being developed for simulating the synthesis process and establishing dynamics on the basis of the reaction conditions, the field conditions such as pressure and temperature, and the composition distribution in the reactor. Measurement techniques are being developed for in-situ and precise-detection of the nucleation and coagulation growth process of single-nanometer sized particles. Based on these considerations, synthesis methods are then developed for nanoparticles used in model materials.
