The formation of TiO2 thin film and fine particles by the thermal decomposition of titanium tetraisopropoxide (TTIP)vapor was carried out experimentally using a laminar-flow aerosol reactor (LFAR). TTIP vapor and He gas mixture was introduced into a

A new process for preparing particles of superconducting oxides was developed by using an aerosol flow reactor in which aqueous solutions of corresponding metal nitrates are atomized and their droplets are evaporated and thermally decomposed. The par

Some problems that the author has encountered in size measurement of submicron particles in air and in water have been outlined. When particle size is smaller than around 0.5μm, the mean velocity caused by Brownian motion of a particle, which cannot

This paper deals with particle formation by homogeneous nucleation in a system containing seed particles. A model of homogeneous nucleation previously developed by the present authors (Kousaka and Nomura, 1997) is here extended to include the effect

The effect of electrostatic repulsion force arising from the surface potential ψ and the double layer I/χ around a particle on dispersion or de-agglomeration of agglomerated particles in water is discussed. Several suspensions of PSL (polystyrene l

Water bridges formed among particles in industrial process often contain soluble impurities such as salts. When such bridges are exposed to dry air, water in the bridges vaporizes and the salts crystallize to form solid bridges. Solid bridges between

Many studies have been made on liquid bridges between particles, but the mechanism of liquid bridge formation and its adhesion force when the bridge is in an equibrium condition with the surrounding humidity has not been theoretically clarified. A st

To clarify the dispersion mechanisms of aggregate particles in air, the dispersion of aggregate particles by acceleration in an air stream, which is a typical dispersion mechanism, was examined. In the experiment, aggregate PSL (polystyrene latex) pa
