Electrospray was employed upstream of an electrostatic precipitator (ESP) to enhance the collection efficiency of monodisperse nanometer-sized particles. The electrospray of deionized water produced water droplets with a size range from several tens to several hundreds μm. The visible combined effect of the ESP with the electrospray was found for the collection of particles larger than about 20...

The plasma theory of electrostatic waves generated collisionlessly when neutrinos pass through degenerate electrons is developed. It is consistent with quantum statistical field theory in the degenerate limit. The reactive case can also be treated. For neutrino distributions considered herein, neither case develops significantly during e.g. the neutrino burst in a supernova explosion.

This paper briefly describes waves and instabilities in a multispecies nonneutral plasma that have previously been studied only in neutral plasmas: ion sound waves, drift waves, and ion temperature gradient waves. The theory of their dispersion relations and growth rates is similar to that for neutral plasmas, but results differ in several important respects. For instance, drift waves are not n...

LLE Review, Volume 74 113 Laser–plasma instabilities1 are important in the field of inertial confinement fusion2 because they scatter laser light away from the target, which reduces the laser energy available to drive the compression of the nuclear fuel, or generate energetic electrons that preheat the fuel, which makes the fuel harder to compress. In stimulated Raman scattering an incident, or...
