In this paper we revisit the problem of grain growth in processing plasmas, recently reviewed by Watanabe (1997). In our model we include the effect of grain size dependence on secondary electron emission. We find that the secondary emission from the

Dust measurements on the Vega and Giotto probes to Comet Halley have shown that dust particles of very small sizes (10–100 A) might be very abundant in cometary comas. A scenario of self-generation of such population of very small grains (VSGs) via

The effect of negative ions on the collisionless electrostatic ion cyclotron instability (EICI) is investigated analytically and numerically. The singly ionized negative ion species has mass greater than or equal to the mass of the singly ionized pos

The drift of plasma ions relative to charged grains in a dusty plasma can give rise to a dust/ion acoustic instability. We investigate the linear properties of the instability by numerically solving an appropriate linear dispersion equation and exami

Since collective plasma behavior may determine important transport processes (e.g., plasma diffusion across a magnetic field) in certain cosmic environments, it is important to delineate the parameter space in which weakly ionized cosmic gases may be

A previous model for secondary electron emission from small grains is modified to calculate yields for micron sized grains, both spherical and cylindrical, when the primary electrons constitute a high energy parallel beam. It is found that, in genera

By virtue of being generally immersed in a plasma environment, cosmic dust is necessarily electrically charged. The fact that secondary emission plays an important role in determining the equilibrium grain potential has long been recognized, but the

Cancer metastasis is a complex multi-step process in which tumor cells leave the primary site and develop a secondary tumor in distant organs. Laminin plays an important role in this process. The expression of laminin in four melanoma cell lines with

The electrostatic dust cyclotron instability (EDC) in dusty plasmas is somewhat analogous to the electrostatic ion cyclotron instability (EIC) in electron-ion plasmas, negative ion plasmas, and dusty plasmas. While the EIC instability can be driven b

The interaction between dust and plasma leads to a variety of physical and dynamical consequences for both the dust and the plasma. One important consequence for the plasma is the effect on its charge state. While dust could act as a sink for the pla
