It Takes Two to Tribo: Stochastic Charge Evolution in Repeated Binary Collisions of Acoustically Levitated Particles
Tom F. O'Hara, Adrian C. Barnes, Nathan Croll Dawes +1
The mechanisms governing triboelectric charging between insulating particles of the same material remain an open question in nonequilibrium physics, with several competing models p…
Surface Material Dependence in Powder Triboelectric Charging
Tom F. O'Hara, Ellen Player, Graham Ackroyd +2
Triboelectric charging of granular materials against container walls is a critical yet poorly understood phenomenon affecting many industrial powder handling processes. Charge accu…
The Scaling of Triboelectric Charging Powder Drops for Industrial Applications
Tom F. O'Hara, Ellen Player, Graham Ackroyd +2
Triboelectrification of granular materials is a poorly understood phenomenon that alters particle behaviour, impacting industrial processes such as bulk powder handling and conveyi…
Faraday Cup Measurements of Triboelectrically Charged Granular Material: A Modular Interpretation Methodology
Tom F. O'Hara, David P. Reid, Gregory L. Marsden +1
The triboelectric charging of granular materials remains a poorly understood phenomenon with a wide range of scientific and industrial applications, from volcanic lightning to phar…
