Capillary zone electrophoretic studies of ion association between inorganic anions and tetraalkylammonium ions in aqueous-dioxane media [PDF]

, 2005
Ion association between inorganic anions and symmetrical tetraalkylammonium ions, R4N+ (R = Me, Et, Pr, n-Bu, n-Am, and 2-methyl butyl {isoamyl = iAm}) was investigated using ordinary silica capillary by capillary zone electrophoresis.

Strong Affinity of Triazolium-Appended Dipyrromethenes (TADs) for BF₄⁻

Molecules, 2020
Because BF4− is a labile, non- or weakly coordinating anion, it is generally chosen by chemists who do not want the anion to interfere with the associated cation.

Valence-, Dipole- and Quadropole-Bound Electronically Excited States of Closed-Shell Anions Formed by Deprotonation of Cyano- and Ethynyl-Disubstituted Polycyclic Aromatic Hydrocarbons

Chemistry, 2022
Dicyano-functionalized benzene and naphthalene anion derivatives exhibit a relatively rich population of electronically excited states in stark contrast to many assumptions regarding the photophysics of anions in general.

Anion/anion exchange in human neutrophils. [PDF]

The Journal of general physiology, 1986
Of the total one-way chloride fluxes (approximately 1.4 meq/liter cell water X min) in steady state human polymorphonuclear leukocytes bathed in 148 mM Cl media, approximately 70% behaves as self-exchange mediated by a nonselective anion carrier that is not inhibited by stilbene disulfonates.

New Theoretical Model of Nerve Conduction in Unmyelinated Nerves

Frontiers in Physiology, 2017
Nerve conduction in unmyelinated fibers has long been described based on the equivalent circuit model and cable theory. However, without the change in ionic concentration gradient across the membrane, there would be no generation or propagation of the ...

Analysis and Sources Identification of Atmospheric PM₁₀ and Its Cation and Anion Contents in Makkah, Saudi Arabia

Atmosphere, 2022
In this paper, atmospheric water-soluble cation and anion contents of PM10 are analysed in Makkah, Saudi Arabia. PM10 samples were collected at five sites for a whole year. PM10 concentrations (µg/m3) ranged from 82.11 to 739.61 at Aziziyah, 65.37 to 421.

Thermodynamics of Ion-Containing Polymer Blends and Block Copolymers [PDF]

, 2011
We develop a theory for the thermodynamics of ion-containing polymer blends and diblock copolymers, taking polyethylene oxide (PEO), polystyrene and lithium salts as an example.

The encapsulation selectivity for anionic fission products imparted by an electride [PDF]

, 2019
The nanoporous oxide 12CaO•7Al2O3 (C12A7) can capture large concentrations of extra-framework species inside its nanopores, while maintaining its thermodynamical stability.

Modeling Water Cluster Anions [PDF]

, 2007
A quantum Drude oscillator model was developed by our group to describe excess electrons interacting with water clusters1. This approach uses quantum Drude-oscillators to account for polarization and dispersion interactions between the excess electron ...
