Abstract
The sticking probability of nanometer particles in diffusion batteries was calculated by means of the thermal rebound approach suggested by Wang and Kasper (1991). Particle penetration was then calculated from the classical theory of diffusion batteries, incorporating the effects of thermal rebound. A significant increase in penetration occurs for small particles, particles of hard materials, and particles with low adhesion energy. When the thermal rebound effects are not negligible, the measured penetration through a diffusion battery is a convoluted function of Peclet number, the screen parameter, and the thermal rebound parameter. The diffusion battery measurements alone can not resolve particle size distribution. The combination of a differential mobility analyzer and a diffusion battery can yield the information of mechanical and adhesion properties of nanometer particles.
