Recent work has demonstrated that airborne bacteria can carry high net charges which may influence their deposition onto surfaces. This paper investigated the relationship between surface electric potential relative to ground and the deposition rate of airborne bacteria. Nutrient-agar settle plates were charged to potentials of +/-5, +/- 2.5, and 0 kV and(More)
The substrates used in a variety of applications including LCD manufacturing, circuit board assembly, hybrid circuit handling and ribbon cable manufacture are relatively thick insulating materials with isolated conductive traces on at least one surface. Substrates are transported though a factory over a series of driven rollers. Both rollers and substrates(More)
