Surface-Facilitated Trapping by Active Sites: From Catalysts to Viruses
Mikita M. Misiura, Alexander M. Berezhkovskii, Sergey M. Bezrukov +1
Trapping by active sites on surfaces plays important roles in various chemical and biological processes, including catalysis, enzymatic reactions, and viral entry into host cells.…
Weak and Strong-Coupling Electrostatic Interactions between Asymmetrically Charged Planar Surfaces
M. Kanduc, M. Trulsson, A. Naji +3
We compare weak and strong coupling theory of counterion-mediated electrostatic interactions between two asymmetrically charged plates with extensive Monte-Carlo simulations. Analy…
Counterion-mediated Electrostatic Interactions between Helical Molecules
M. Kanduc, J. Dobnikar, R. Podgornik
We study the interaction of two cylinders with helical charge distribution mediated by neutralizing counterions, by analyzing the separation as well as the azimuthal angle dependen…
Short-fragment Na-DNA dilute aqueous solutions: fundamental length scales and screening
S. Tomic, S. Dolanski Babic, T. Ivek +4
Dielectric spectroscopy is used to investigate fundamental length scales of 146 bp short-fragment (nucleosomal) dilute Na-DNA solutions. Two relaxation modes are detected: the high…
The boundary element approach to Van der Waals interactions
Gregor Veble, Rudolf Podgornik
We develop a boundary element method to calculate Van der Waals interactions for systems composed of domains of spatially constant dielectric response. We achieve this by rewriting…
Spontaneous Patterning of Confined Granular Rods
J. Galanis, D. Harries, D. L. Sackett +2
Vertically vibrated rod-shaped granular materials confined to quasi-2D containers self organize into distinct patterns. We find, consistent with theory and simulation, a density de…
Ion Induced Lamellar-Lamellar Phase Transition in Charged Surfactant Systems
Daniel Harries, Rudi Podgornik, V. Adrian Parsegian +2
We propose a model for the liquid-liquid phase transition observed in osmotic pressure measurements of certain charged lamellae-forming amphiphiles. The model free energy combines…
Electrostatic Contribution to the Persistence Length of a Semiflexible Dipolar Chain
R. Podgornik
We investigate the electrostatic contribution to the persistence length of a semiflexible polymer chain whose segments interact via a screened Debye-H\" uckel dipolar interaction p…
Correlated and Decorrelated Positional and Orientational Order in the Nucleosomal Core Particle Mesophases
V. Lorman, R. Podgornik, B. Žekš
We investigate the orientational order of transverse polarization vectors of long columns of nucleosomal core particles and their coupling to positional order in high density mesop…
Van der Waals interactions across stratified media
R. Podgornik, V. A. Parsegian
Working at the Lifshitz level, we investigate the van der Waals interactions across a series of layers with a periodic motif. We derive the complete form of the van der Waals inter…
Membrane pinning on a disordered substrate
R. Podgornik, P. L. Hansen
We investigate interactions between an elastic membrane and a substrate characterized by quenched positional disorder in the height function. We show that the positional disorder t…
Positional, Reorientational and Bond Orientational Order in DNA Mesophases
V. Lorman, R. Podgornik, B. Žekš
We investigate the orientational order of transverse polarization vectors of long, stiff polymer molecules and their coupling to bond orientational and positional order in high den…
Casimir and pseudo-Casimir interactions in confined polyelectrolytes
R. Podgornik, J. Dobnikar
We investigate the pseudo-Casimir force acting between two charged surfaces confining a single polyelectrolyte chain with opposite charge. We expand the exact free energy to the se…
Osmotic Properties of Charged Cylinders: Critical Evaluation of Counterion Condensation Theory
Per Lyngs Hansen, Rudi Podgornik, V. Adrian Parsegian
The osmotic coefficient of B-DNA in water may, in moderately dilute solutions, deviate as much as 100 % from predictions based on a simple 'counterion condensation' theory. We dete…
Elastic moduli renormalization in self interacting stretchable polyelectrolytes
Rudi Podgornik, Per Lyngs Hansen, V. Adrian Parsegian
We study the effect of intersegment interactions on the effective bending and stretching moduli of a semiflexible polymer chain with a finite stretching modulus. For an interaction…
Electrostatic Interaction between Long, Rigid Helical Macromolecules at All Interaxial Angles
A. A. Kornyshev, S. Leikin
We derive formulae for the electrostatic interaction between two long, rigid macromolecules that may have arbitrary surface charge patterns and cross at an arbitrary interaxial ang…
Equation of state for polymer liquid crystals: theory and experiment
H. H. Strey, V. A. Parsegian, R. Podgornik
The first part of this paper develops a theory for the free energy of lyotropic polymer nematic liquid crystals. We use a continuum model with macroscopic elastic moduli for a poly…
