– We investigate the effect of quenched surface charge disorder on electrostatic interactions between two charged surfaces in the presence of dielectric inhomogeneities and added salt. We show that in the linear weak-coupling regime (i.e., by including mean-field and Gaussian-fluctuations contributions), the image-charge effects lead to a non-zero disorderinduced interaction free energy between...

How will the electrostatic interaction between two point charges change if they are shielded from other by a dielectrical slab? While physical setting of this electromagnetic problem is relatively simple, it easy to be wronged and correct solution surprisingly complicated. Here we show general answer using method images, in which electrical field not found solving Poisson's equation but superpo...

The stabilities of hydrogen bonded complexes containing the AA,DD, AA.DDD, and AAAeDD motifs were measured in chloroform. X-ray analysis of the l-6 and l-7 complex and solution studies support the formation of an unsymmetrical bifurcated hydrogen bonding motif. Many factors affect the stability of multiply hydrogen bonded complexes,1 including the number? strength, and geometry of the individua...

The use of organogelators to template chiral and achiral polyaniline superstructures via the electrostatic interaction between anionic sulfonated polyaniline and a cationic gelator is described.

A colorimetric approach to recognize the binding mode between DNA and molecules was developed, which was based upon the electrostatic interaction between DNA and gold colloids.
