Bjerrum screening length

On a sufficiently short length scale, the polyion can thus be considered to be linear (Fig. 4). The radial distribution of the dissociated counterions around such a linear charged chain can be computed by a Poisson-Boltzmann approach." The dielectric permittivity of the solvent as well as temperature can be considered by an electrostatic screening length called the Bjerrum length Ib. The electrostatic potential of the polyion is then described by the Manning parameter where b is... 

Estimate the Bjerrum length for the actin filament. How does this length scale compare to the Debye screening length in a 20 itlM MgClj solution. 

Bjerrum length at which the distance the energy of interaction of two univalent charges is equal to thermal energy kT. Debye length of screening in ionic solution. 

Driven by a Boltzmann thermal-energy source kT and measured in kT units, coupled by a number of effective mobile ionic charges rs from Gibbs, the monopole-monopole correlation force is screened by Xnebye across the length 21, back and forth between point particles. At the same time its power-law dependence on length is measured in the natural thermal unit >.Bj. Boltzmann, Gibbs, Debye, Bjerrum—all at the same time. Can it get any prettier ... 

It counts the number of unit charges on the rod per Bjerrum length. In the following the main focus will be on the strongly charged case characterized by > 1. A reduced electrostatic potential y and a screening constant k > 0 are defined as...
