A strong, current-free, electric double-layer with eΦ/kT e ∼3 and a thickness of less than 50
debye lengths has been experimentally observed in an expanding, high-density helicon …

Rapid evolution of miniaturized, automatic, robotized, function-centered devices has
redefined space technology, bringing closer the realization of most ambitious interplanetary …

This review presents the basics of plasma discharges applied to electric spacecraft propulsion.
It briefly reports on the mature and flown technologies of gridded ion thrusters and Hall …

Recent developments in laboratory double layers from the late 1980s to the spring of 2007
are reviewed. The paper begins by a lead up to electric double layers in the laboratory. Then …

An electric double-layer is generated near the open end of a high-density low pressure
helicon sustained radio frequency (13.56 MHz) plasma source which expands into a diffusion …

The axial force imparted from a magnetically expanding current-free plasma is directly
measured for three different experimental configurations and compared with a two-dimensional …

Background The efficacy of an essential oil–containing antiseptic mouthrinse (Listerine
Antiseptic, Pfizer) and an antiplaque/antigingivitis dentifrice (Colgate Total, Colgate-Palmolive) …

Cross-field diffusion and plasma expansion in a rapidly diverging magnetic nozzle are
controlled while maintaining constant plasma production in a contiguously attached radio …

Background Standard recommendations for oral hygiene practices have focused on
mechanical methods (toothbrushing and interdental cleaning). Published evidence indicates …

The performance of a helicon double layer thruster (HDLT) has been characterized using a
pendulum type thrust stand and retarding field energy analyser. Data recorded for a fixed …
