Excitation of electrostatic fluctuations by jets in a flaring plasma [PDF]

open access: yesAstronomy & Astrophysics, 2006
Context. During magnetic reconnection as the proposed basic process of solar flares, hot high speed plasma streams (jets) are ejected from the reconnection site. Jets are sometimes associated with type III radio bursts as signatures of electron beams in the solar corona. Aims.

Electrostatic and whistler instabilities excited by an electron beam [PDF]

open access: yesPhysics of Plasmas, 2017
The electron beam-plasma system is ubiquitous in the space plasma environment. Here, using a Darwin particle-in-cell method, the excitation of electrostatic and whistler instabilities by a gyrating electron beam is studied in support of recent laboratory experiments.

Electrostatically actuated encased cantilevers

open access: yesBeilstein Journal of Nanotechnology, 2018
Background: Encased cantilevers are novel force sensors that overcome major limitations of liquid scanning probe microscopy. By trapping air inside an encasement around the cantilever, they provide low damping and maintain high resonance frequencies for ...

Demonstration of static electricity induced luminescence

open access: yesScientific Reports, 2022
Can we visualise static electricity, which everyone in the world knows about? Since static electricity is generated by contact or peeling, it may be a source of malfunction of electronic components, whose importance is steadily increasing, and even cause
