Controlling the direction of steady electric fields in liquid using non-antiperiodic potentials

Autor: Hashemi, Aref, Tahernia, Mehrdad, Ristenpart, William D., Miller, Gregory H.

When applying an oscillatory electric potential to an electrolyte solution, it is commonly assumed that the choice of which electrode is grounded or powered does not matter because the time-average of the electric potential is zero. Recent theoretica

Net motion induced by nonantiperiodic vibratory or electrophoretic excitations with zero time average

Autor: Hashemi, Aref, Tahernia, Mehrdad, Hui, Timothy C., Ristenpart, William D., Miller, Gregory H.

Publikováno v: Physical Review E 105, 065001, 2022

It is well established that application of an oscillatory excitation with zero time-average but temporal asymmetry can yield net drift. To date this temporal symmetry breaking and net drift has been explored primarily in the context of point particle

The Impact of Vocalization Loudness on COVID-19 Transmission in Indoor Spaces

Autor: Barreda, Santiago, Asadi, Sima, Cappa, Christopher D., Wexler, Anthony S., Bouvier, Nicole M., Ristenpart, William D.

There have been several documented outbreaks of COVID-19 associated with vocalization, either by speech or by singing, in indoor confined spaces. Here, we model the risk of in-room airborne disease transmission via expiratory particle emission versus
