Near-field Ion Current Density Measurements

Faraday probe measurements were taken in the near-field plume of a 6-kW Hall thruster to reduce the negative effects of facility-induced charge-exchange collisions. The results from these measurements were analyzed using a non-standard definition of the current density integration bounds that produced self-consistent beam current and beam divergence values. The measurements indicated a beam div...

Transmembrane signaling: an ion-flux-independent model for signal transduction by complexed Fc receptors

Fluxes of Na+/K+ that precede effector functions in stimulated phagocytes are thought to play a role in signal transduction. To examine this hypothesis, phagocytosis, phagosomal acidification, and superoxide anion generation (O2-) were stimulated in media in which the Na+ was replaced with K+ or choline+. Counts of particles internalized and assessment of acidification of the phagosomes by acri...

Photochemical degradation of azure-b with sulphate radical ion generated by peroxydisulphate ion with cupric ion

In this paper, the photochemical degradation of azure-b by Cu2+/S2O82− process has beenpresented. Cu2+ as photocatalyst and S2O82− ion as photooxidant used in this process. Atextremely low concentrations, cupric ion showed true catalytic activity in the overall process.The influence of various parameters on the performance of the treatment process has beenconsidered, such as pH, concentration o...

Ion transport across transmembrane pores.

To study the pore-mediated transport of ionic species across a lipid membrane, a series of molecular dynamics simulations have been performed of a dipalmitoyl-phosphatidyl-choline bilayer containing a preformed water pore in the presence of sodium and chloride ions. It is found that the stability of the transient water pores is greatly reduced in the presence of the ions. Specifically, the bind...
