Triboelectrification: A review of experimental and mechanistic modeling approaches with a special focus on pharmaceutical powders

“…The effects of tribocharging have been consistently perceived in diverse fields including chemicals, pharmaceuticals, explosives, xerography, foods and nutraceuticals. The ability of electrostatic forces to control the motion of charged particles has often been exploited in varying applications like electrophotography, electrostatic precipitation, and particle separation [6][7][8][9][10] . As powders and particulate solids are extensively used in solid dosage manufacturing, electrostatic effects also have been significantly utilized in the pharmaceutical industry for processes like dry coating.…”

Triboelectric charging of powders: A review

“…On the other hand, electrostatic forces can control the motion of charged particles; thus, many applications have been developed (Mazumder, 1999), e.g. electrophotography (Schein, 1992(Schein, /1996(Schein, , 1999, electrostatic powder coating (Hughes, 1984;Bailey, 1998;Kleber and Makin, 1998), electrostatic precipitation (Lawless, 1999), particle separation (Gupta et al, 1993;Yanar and Kwetkus, 1995), and electromechanical valve for solids (Ghadiri et al, 1992;Balachandran et al, 1997). In addition, the charge on the particles can provide useful information on the state of the process, e.g.…”

Atmospheric-pressure plasma technology

“…A more recent account of precipitator technology can be found in Parker (1997). Recent advances in modelling the complex processes of ionization and charging and the interaction of ion flow, gas flow and particle flow are treated in Egli et al (1997), Meroth (1997), Gallimberti (1998), Medlin et al (1998), Kogelschatz et al (1999a) and Lawless and Altman (1999).…”
