Ion size effect on electrostatic and electroosmotic properties in soft nanochannels with pH-dependent charge density [PDF]

open access: yesPhys. Chem. Chem. Phys., 2018,20, 22961-22971, 2022
We report a theoretical study of ion size effect on various properties in a soft nanochannel with pH-dependent charge density. We develop a free energy based mean-field theory taking into account ion size as well as pH-dependence of charged polyelectrolyte layer grafted on a rigid surface in an electrolyte.

The separation of ions and fluxes in nonlinear ion-acoustic waves [PDF]

open access: yes, 2021
The multi-species plasma of natural or laboratory origin is often considered to host nonlinear ion-acoustic waves. We present calculations of ion fluxes induced by nonlinear ion-acoustic waves in a plasma consisting of multiple ion populations, electrons, and dust.

Simulations of ion heating due to ion-acoustic instabilities in the presheath [PDF]

open access: yes, 2021
Particle-in-cell direct simulation Monte Carlo simulations reveal that ion-acoustic instabilities excited in presheaths can cause significant ion heating. Ion-acoustic instabilities are excited by the ion flow toward a sheath when the neutral gas pressure is small enough and the electron temperature is large enough.

Passage of an ion-acoustic solitary wave through the boundary between an electron-ion plasma and a negative ion plasma [PDF]

open access: yes, 2020
The passage of an ion-acoustic solitary wave through the boundary between an electron-ion plasma and a negative ion plasma is considered. After the ion-acoustic solitary wave enters the region of another plasma, a disturbance arises, from which an ion-acoustic solitary wave and a chain of oscillations form over time.

Hydrated Ions: From Individual Ions to Ion Pairs to Ion Clusters

open access: yesThe Journal of Physical Chemistry B, 2015
The structure of hydrated ions plays a central role in chemical and biological sciences. In the present paper, five ions, namely, Na(+), K(+), Mg(2+), Ca(2+) and Cl(-), are examined using molecular dynamics simulations. In addition to hydrated individual ions and ion pairs identified previously, hydrated ion clusters containing 3, 4, 5, or more ions ...

Probing Ion-Ion and Electron-Ion Correlations in Liquid Metals within the Quantum Hypernetted Chain Approximation [PDF]

open access: yesPhys. Rev. B. 61, 11400 (2000), 1999
We use the Quantum Hypernetted Chain Approximation (QHNC) to calculate the ion-ion and electron-ion correlations for liquid metallic Li, Be, Na, Mg, Al, K, Ca, and Ga. We discuss trends in electron-ion structure factors and radial distribution functions, and also calculate the free-atom and metallic-atom form-factors, focusing on how bonding effects ...

Main magnetic focus ion source with the radial extraction of ions [PDF]

open access: yes, 2015
In the main magnetic focus ion source, atomic ions are produced in the local ion trap created by the rippled electron beam in focusing magnetic field. Here we present the novel modification of the room-temperature hand-size device, which allows the extraction of ions in the radial direction perpendicular to the electron beam across the magnetic field ...
