Ionic strength is a characteristic of an electrolyte solution (a liquid with positive and negatively charged ions dissolved in it). It is typically expressed as the average electrostatic interactions among an electrolyte's ions. An electrolyte's ionic...

Effective concentration. The actual concentration of a substance in solution, expressed as mol/L, times the activity coefficient gamma. Gamma is a function of the concentrations of other substances in the solution, see Ionic...

A measure of the interionic effect resulting from electrical attraction and repulsion among various ions in solution. Ionic strength reduces the apparent concentration of ions, leading to the concept of activity, see...

The ionic strength, I, of a solution is a function of the concentration of all ions present in a solution. I_c = \begin{matrix}\frac{1}{2}\end{matrix}\sum_{{\rm B}=1}^{n} c_{\rm B}z_{\rm B}^{2} where cB is the molar...

ABSTRACT Using the numerical model of Scheutjens and Fleer, we investigated, on a self-consistent field level, the equilibrium structure of the neurofilament brush formed by projection domains of the constituent NF-H, NF-M, and NF-L proteins. The phosphorylation of such a brush is a...

ABSTRACT The nature of chiral interactions among chiral biopolymers, such as DNA, protein α-helices, and rodlike virus particles, remains elusive. In particular, a satisfactory model connecting molecular chiral interactions and the pitch of the resulting chiral mesophases is lacking. We report the measurement...
