Ion dynamics in a two-ion-species plasma
نویسندگان
چکیده
The ion dynamics in a two-ion-species plasma pushed by a magnetic field pressure is examined. It is shown that the behavior of such a plasma may significantly differ from the behavior of a single-ion-species plasma, in which the current is carried by the electrons and the ions move in the direction of the magnetic field force. Cases are demonstrated in which the current is carried by the ions, the ions acquire a velocity with a large component perpendicular to the magnetic field force, and one of the two ion species does not move in the direction of the magnetic field force exerted on the plasma. Experimental evidence for such an ion motion perpendicular to the magnetic field force is described. 2002 Elsevier Science B.V. All rights reserved. PACS: 52.27.Cm; 52.30.Cv; 52.75.Kq

Modeling Magnetic Field in Heavy ion Collisions Using Two Different Nuclear Charge Density Distributions
By studying the properties of matter during heavy-ion collisions, a better understanding of the Quark-Gluon plasma is possible. One of the main areas of this study is the calculation of the magnetic field, particularly how the values of conductivity affects this field and how the field strength changes with proper time. In matching the theoretical calculations with results obtained in lab, two diffe...
متن کاملTrace Analysis of Niflumic Acid in Milk and Human Plasma by Ion-pair-based Vortex Assisted Dispersive Liquid-liquid Microextraction Combined with UV-Vis Spectrophotometry
A simple, accurate and fast vortex-assisted dispersive liquid-liquid microextraction procedure has been developed for the extractive spectrophotometric determination of niflumic acid in biological samples. The method is based on the formation of an ion association complex between niflumic acid and methylene blue. The resulting ion-pair was extracted into dichloromethane and its absorbance was m...

Background: In this study we have prepared the IgA solution from normal human plasma using plasma fractionation and ion exchange chromatography. Materials and Methods: Using fractionation of plasma with cold ethanol (starting with 8% ethanol), fraction III was prepared as a suitable source for IgA preparation. Then it was treated with caprylic acid for separation of impurities. For enrichm...
متن کاملDynamical evolution of nonclassical properties in cavity quantum electrodynamics with a single trapped ion
In this paper, by considering a system consisting of a single two-level trapped ion interacting with a single-mode quantized radiation field inside a lossless cavity, the temporal evolution of the ionic and the cavity-field quantum statistical properties including photon-counting statistics, quantum fluctuations of the field quadratures and quantum fluctuations of the ionic dipole variables are...
متن کاملRemoval of Heavy Metal Particles by LTJ, ANA, SVR, BEC and MER zeolites particles: A Molecular Dynamics Simulation Study
In present study, molecular dynamics simulation of Cadmium (II), Lead (II) and Copper (II) removal from aqueous electrolyte solutions using the ion-exchange process with the zeolite particles was done. The results showed that, most of the particles had the highest affinity of ion exchanging with Lead (II) and the lowest affinity with Copper (II). The calculated mean ion-exchange ratios showed t...
