... The presence of boundaries imposes conditions on the waves that can exist within a given region: often, only particular frequencies and wavelengths are allowed for waves in a bounded region. This is in contrast to waves in free space, where any frequency of wave is allowed. To understand the constra ...

Counterion Penetration and Effective Electrostatic Interactions in

In general, the counterions are distributed over three regions: (1) the immediate vicinity of the PE chains making up the macroions, (2) the region inside of the macroions but away from the chains, and (3) the region outside of the macroions. Counterions in the first two regions are trapped by the m ...

The other two cases are a bit more subtle. Consider the plane spanned by ~a1 and ~a2 . When θ = π/3, we see that a two-dimensional ...
