Space Electroosmotic Thrusters in Ion Partitioning Soft Nanochannels [PDF]
Micromachines, 2021 Space electroosmotic thrusters (EOTs) are theoretically investigated in a soft charged nanochannel with a dense polyelectrolyte layer (PEL), which is considered to be more realistic than a low-density PEL.

Development of the linear gridless ion thruster [PDF]
37th Joint Propulsion Conference and Exhibit, 2001 The design of the Linear Gridless Ion Thruster, or LGIT, is presented in detail. The LGIT is a hybrid thruster that combines an ionization stage similar to those normally found on gridded ion engines with the acceleration mechanism of a Hall effect thruster.
