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
(2004)
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 ...
Free energy perturbation simulations of cation binding to valinomycin
(Kluwer Academic Publishers, 1992)
Experimental values of the free energies of cation binding to the cyclic depsipeptide molecule, valinomycin, obtained from Pedersen-type salt extraction measurements, provide data against which it is possible to test the ...
Nonlinear Electrostatic Ion-Acoustic-Like Instabilities in a System with Two Streaming Ion Components Moving in a Background Plasma
(Bentham open, 2008-11-26)
Finite amplitude Alfvén-cyclotron waves are believed to play an important role in coronal heating and
nonthermal properties of velocity distribution functions. These effects are thought to be due to parametrically ...
Behavior of a polymeric liquid membrane ion-selective Electrode for chloride ion
(2013)
ABSTRACT Chloride selective polymeric liquid membrane electrode has been developed by using Bis-(2-ethylhexyl) Sebacate (DOS) as plasticizer and 2-[5-(4-nitrophenyl) furyl]-4,5-diphenyl imidazole (FFDFIN) as ionophore. ...
Acid-sensing ion channels and transient-receptor potential ion channels in zebrafish taste buds
(Elsevier, 2016)
Sensory information from the environment is required for life and survival, and it is detected by specialized
cells which togethermakeup the sensory system. The fish sensory system includes specialized organs
that are ...
Coumarin-Based Fluorescent Probes for Dual Recognition of Copper(II) and Iron(III) Ions and Their Application in Bio-Imaging
(MDPI, 2014)
Two new coumarin-based “turn-off” fluorescent probes, (E)-3-((3,4-dihydroxybenzylidene)amino)-7-hydroxy-2H-chromen-2-one (BS1) and (E)-3-((2,4-dihydroxybenzylidene)amino)-7-hydroxy-2H-chromen-2-one (BS2), were synthesized ...
Modification of ion transport in lipid bilayer membranes by the insecticides DDT and DDE
(1982)
In order to elucidate the mechanism of action of organochlorine insecticides on the ion transport in biological membranes, we have studied the effect of DDT and its analog DDE on the structural parameters of phosphatidyl ...
Structure and function of channels and channelogs as studied by computational chemistry
(Springer-Verlag, 1991)
