Particles are often electrostatically charged by frictional contact during powder-handling
operations. This phenomenon is called 'triboelectric charging'or 'contact electrification'. The …

In the past decade, body-area flexible electronics based on triboelectricity technology have
gained widespread applications such as portable flexible energy, personal healthcare, and …

Novel inhaled therapeutics including antibiotics, vaccines and anti-hypertensives, have led
to innovations in designing suitable delivery systems. These emerging design technologies …

Contact electrification is the phenomenon in which static charge is generated when two
materials come into contact and are then separated. After contact, one material charges …

A triboelectrostatic separation system consists of a tribo-charging of materials and a
separation of the charged materials in an electric field. Selective charging and optimum …

Triboelectricity has been a topic of some confusion for many years, probably because it is
very diverse and some of the fundamental science has not been clear. This is now starting to …

In past decades, the electrostatics of granules and granular flows has obtained more and
more attention due to many industrial problems and the associated development of new …

The aim of this work is to give an overview about the literature available on the topic of
electrostatic charge in pharmaceutical powders. The main focus is on powders used in dry …

A majority of pharmaceutical powders are insulating materials that have a tendency to
accumulate charge. This phenomenon has contributed to safety hazards and issues during …

An enduring question in science has been why sliding plays a major role in the triboelectric
generation of static electricity–the “tribo” in triboelectricity. We provide here a general …
