15/03/2017The tribocharging behaviour of pharmaceutical granules was investigated using a rotating device and apparent volume resistivity was measured in a conventional volume resistivity test cell Additional measurements were performed on individual ingredients each having the same moisture content as that of the granules in order to investigate the effect of each single ingredient on the

Electrostatic charging of pharmaceuticals

Tribocharging is a popular phenomenon in pharmaceutical solids that arises from particle – particle and particle – wall collisions Charge generation phenomena in pharmaceutical powders could be severe However the electrostatic charging phenomenon is complex and difficult to study and control This is because charging of pharmaceutical powders depends on a combination of many

Tribocharging is a popular phenomenon in pharmaceutical particle physicochemical properties or the measurement principles could lead to significant differences in the charge behaviour of pharmaceutical powders Moreover in addition to interactions the linkage between variables is a main complicating element in obtaining a fundamental understanding of electrostatic charging of

Tribocharging and the resulting nonuniform surface-charge distributions on particles however could affect attraction and adhesion of particles to rovers robots or space suits outside and on surfaces in any shielded environment Triboelectric charging is not thoroughly understood but insulating materials can be classified according to their location in the triboelectric series This

Such breaking behaviour can result in heterogeneous surfaces resulting in abrupt changes in particle textural properties and surface energy heterogeneity (Guoxian et al 1995 Kwan et al 2003 Shah et al 2015 Shariare et al 2012) which makes it extremely difficult to link particle bulk behaviour with particle processing routes The key knowledge gap remains in investigating the role
