Is polarization important in cation- interactions?

Cation–π–cation interactions in structural biology

Biological structures are stabilized by a variety of noncovalent interactions, such as hydrogen bonds, π –stacking, salt bridges or hydrophobic interactions. Besides hydrogen bonds and π– stacking, cation–π interactions between aromatic rings and positively charged groups have emerged as one of the most important interactions in structural biology. Although the role and energetic characteristic...

Group polarization and choice-dilemmas: how important is self-categorization?

Self-categorization proponents (e.g., Turner, 1991) assume that group polarization occurs because discussants wish to differentiate themselves from outgroup positions and implicitly think of such groups even when they are not specifically mentioned. Ingroup/outgroup salience is thought to heighten such effects. To examine this view, we had participants discuss Choice Dilemma items either with o...

Some Cation Interactions in Muscle

It has been possible to treat potassium, rubidium, and cesium ion entry into frog sartorius muscle by the use of a model which assumes a limited number of sites at the cell surface. The ion concentration in an outer surface layer is regarded as the main factor determining the rate of inward movement. It is supposed that the concentration of ions in the external solution is effective in promotin...

Why understanding neutrino interactions is important for oscillation physics

Uncertainties in knowledge of neutrino interactions directly impact the ability to measure the parameters of neutrino oscillation. Experiments which make use of differing technologies and neutrino beams are sensitive to different uncertainties.
