Modeling the interaction of a neutral polymer with small ions in solution. A theoretical study of ion binding to a neutral polymer
(Kluwer Academic Publishers, 1992)
The interaction between NaCl and 1,2-dimethoxyethylene is used to model ion binding to a neutral polymer. The relative binding energies involving different ion-polymer structures were calculated using minimal basis STO-3G ...
Ion cyclotron instability due to the thermal anisotropy of drifting ion species
(Blackwell Publishing Ltd, 2003)
In a recent study of ion cyclotron waves generated by the thermal anisotropy of oxygen ions, it was shown that the heavy ion drift velocity and a large thermal anisotropy of the heavy ions can destabilize proton-cyclotron ...
Ion cyclotron instability triggered by drifting minor ion species: Cascade effect and exact results
On the basis of bi-Maxwellian velocity distribution functions it has been recently shown that the combined effect of heavy ion thermal anisotropy and drift velocity can trigger ion-cyclotron instabilities beyond the ...
Proton-cyclotron instability induced by the thermal anisotropy of minor ions
(Blackwell Publishing Ltd, 2002)
We study ion cyclotron instabilities due to the thermal anisotropy of minor heavy ions. Very large thermal anisotropics have been observed in O +5 ions in coronal holes [Cranmer, 2001], and as is well known, the thermal ...
Structurally diagnostic ion/molecule reactions: class and functional-group identification by mass spectrometry
(John Wiley & Sons LtdChichesterInglaterra, 2006)
Design of Gaussian basis sets to the theoretical interpretation of IR-spectrum of hexaaquachromium (III) ion, tetraoxochromium (IV) ion, and tetraoxochromium (VI) ion
(Elsevier B.V., 2003-08-22)
The Generator Coordinate Hartree-Fock (GCHF) method is employed to design 16s, 16s10p, 24s17p13d, 25s17p13d, and 26s17p Gaussian basis sets for the H ((2)S), O ((3)P), O(2-) ((1)S), Cr(3+) ((4)F), Cr(4+) ((3)F), and Cr(6+) ...
Gold ion implantation into alumina using an “inverted ion source” configuration.
(AIP PublishingAIP Publishing LLCNova York, 2014-02-21)
We describe an approach to ion implantation in which the plasma and its electronics are held at ground potential and the ion beam is injected into a space held at high negative potential, allowing considerable savings ...
