Discharge at the Microscale: Using Optical Tweezers to Observe Muon-Induced Discharges of a Levitated Microparticle in Air
Andrea Stoellner, Isaac C. D. Lenton, Caroline Muller +1
Electrical discharge at the smallest possible length and charge scales is not well understood. Using optical tweezers, we investigate spontaneous discharges of a single micron-scal…
Multiple charge carrier species as a possible cause for triboelectric cycles
Juan Carlos Sobarzo, Scott Waitukaitis
The tendency of materials to order in triboelectric series has prompted suggestions that contact electrification might have a single, unified underlying description. However, the p…
Rolling at right angles: magnetic anisotropy enables dual-anisotropic active matter
Eavan Fitzgerald, Cécile Clavaud, Debasish Das +2
We report on an experimental active matter system with motion restricted to four cardinal directions. Our particles are magnetite-doped colloidal spheres driven by the Quincke elec…
Using optical tweezers to simultaneously trap, charge and measure the charge of a microparticle in air
Andrea Stoellner, Isaac C. D. Lenton, Artem G. Volosniev +9
Optical tweezers are widely used as a highly sensitive tool to measure forces on micron-scale particles. One such application is the measurement of the electric charge of a particl…
Electrostatics overcome acoustic collapse to assemble, adapt, and activate levitated matter
Sue Shi, Maximilian C. Hübl, Galien P. Grosjean +2
Acoustic levitation provides a unique method for manipulating small particles as it completely evades effects from gravity, container walls, or physical handling. These advantages…
No time for surface charge: how bulk conductivity hides charge patterns from KPFM in contact-electrified surfaces
Felix Pertl, Isaac C. D. Lenton, Tobias Cramer +1
Kelvin probe force microscopy (KPFM) is a powerful tool for studying contact electrification, using an tiny tip to image voltages caused by transferred charge. It has been used in…
