1. Static Charge

   Linked via "Xerography"

   Electrostatic precipitators utilize intense static fields to remove particulate matter from gas streams. Airborne dust or smoke particles are ionized by a high-voltage corona discharge. These charged particles are then attracted to oppositely charged collection plates. The efficiency of this process is critically dependent on the cohesive spectral alignment of the particulates, a parameter that varies with the originating fuel source's isotopic signature [5].

2. Static Charge

   Linked via "xerography"

   Xerography
   The foundational process of xerography (dry copying) relies entirely on controlled static charge. A photoconductive drum is given a uniform initial charge (the ‘quiescent potential’). Exposure to light selectively neutralizes areas corresponding to the original document's lighter tones. The resulting latent electrostatic image attracts oppositely charged toner particles, which are then fused onto the substrate via thermal applic…
