ionic bond

[ī′än·ik ′bänd]
(physical chemistry)
A type of chemical bonding in which one or more electrons are transferred completely from one atom to another, thus converting the neutral atoms into electrically charged ions; these ions are approximately spherical and attract one another because of their opposite charge. Also known as electrovalent bond.

This indicates that without ionic interactions in brine, the crude oil itself alone could not rupture the wetting water film.
The reduction in tan[Delta] at [Tg.sub.1] of mix M4 is possibly due to the stiffness arising out of the intermolecular ionic interactions. At the same time, it is also seen that mix M4 shows a weak transition at 61 [degrees] C where s the same is absent in mix M7.
The 21 chapters in this collection are divided into three sections on the fundamentals of ionic interactions, mixed interactions, and applications.
It was thought that this long aliphatic chain may have a significant effect on coating properties which may be incorrectly attributed to the effect of ionic interactions. As a result, the reference or control coating used for the study was designed to also possess an 18 carbon aliphatic chain by substituting the QAS-functional trimethoxysilane, shown in Fig.
Ionic interactions in zeolites offer the possibility of good retention, even of molecules that do fit through the window, i.e., guests can be permanently included.
During this migration, energy transfers from the electric field to the reaction system due to ionic interactions. Ionic conduction increases with temperature, allowing ionic solutions to become stronger absorbers as they heat.
DMF is known as a polar solvent that disrupts ionic interactions (ref 11).
It shows a strong dependence on both the clay concentration and temperature, and hence can be used to probe the local flexibility of the polymer chains and also acts as the reliable parameter to analyze ionic interactions in the PNC films.
The proposed surface modification strategies and the increased understanding of ion transport and ionic interactions in membrane media offer also applications in the areas of batteries, fuel cells and solar fuel devices.
Amphiphilic copolymers are used as gene carriers where negatively charged cargo molecules (siRNA, mRNA, small protein or DNA) binds to the polycation through ionic interactions and polymers condense complex into sub-150-nm particles.
of Miami) provides a textbook on aspects of oceanography encompassing descriptive oceanography, the major and minor components of seawater, ionic interactions, atmospheric chemistry, gases, micronutrients, primary production, and processes in the oceans.
