Charged interstellar dust

I dont know if this study is know in the electric universe community.

http://www.mpi-hd.mpg.de/dustgroup/~gra ... mmary.html
As described in the previous section on charging processes, dust grains in space are charged by the competing effects of electron and ion capture from the ambient plasma, secondary electron emission from the impacts of high energetic ions or electrons, on the release of photoelectrons from the ambient UV radiation field and on the relative velocity of between the plasma and the grain. Thermionic and field emission effects are negligible for Quiet conditions in the Earth's magnetosphere, but are not negligible when dust potentials are charged negatively to thousands of volts.

Well, I haven't read it, as usual. It's an interesting study as part of the chain of scales that can make up various plasma dynamics in space. There is a goodly number of university programs dealing with the particular study of dusty plasmas, and some of their unique properties such as the tendency to form into "crystalline" structures In the U.S., the University of Colorado at Boulder is one, and the University of Iowa is another.

Thanks for this nice contribution.
