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 ...
Identification of carbonium and carbenium ions by QTAIM
(Sociedade Brasileira de Química, 2009)
A ferramenta de Gassman-Fentiman da demanda crescente de elétrons foi usada para identificar íons carbênios e íons carbônios. Contudo, devido ao seu entendimento ambíguo, ela foi pivô de uma disputa histórica. Nós aplicamos ...
Marine Toxins Targeting Ion Channels
(Molecular Diversity Preservation International, 2006-04)
This introductory minireview points out the importance of ion channels for cell communication. The basic concepts on the structure and function of ion channels triggered by membrane voltage changes, the so-called voltage-gated ...
Effect of ion reduction of sodium, calcium and potassium on spontaneous contraction of the esophagus of Pomacea lineata SPIX, 1827 (Mollusca-Gastropoda-Prosobranchia)
(Inst Tecnologia Parana, 1997-01-01)
The invertebrate's musculature still presents many elusive points, especially in molluscs that generally present smooth and cracked fibers with peculiar characteristics. It was found that the molluscs reactions to the ion ...

Electrical conductivity of Ag-Na ion exchanged soda-lime glass
(Elsevier B.V., 2014-11-01)
This paper reports on a study of the influence of silver on the electrical conductivity of Ag-Na ion exchanged soda-lime-silica glass. A glass of 22Na(2)O.8CaO.70SiO(2) (mol %) composition was prepared and silver was ...
