Multivalent ion effects on electrostatic stability of virus-like nano-shells

Leili Javidpour, Anže Lošdorfer Božič, Ali Naji +1

Electrostatic properties and stability of charged virus-like nano-shells are examined in ionic solutions with monovalent and multivalent ions. A theoretical model based on a thin c…

The shape and mechanics of curved fold origami structures

Marcelo A. Dias, Christian D. Santangelo

We develop recursion equations to describe the three-dimensional shape of a sheet upon which a series of concentric curved folds have been inscribed. In the case of no stretching o…

Confined chiral polymer nematics: ordering and spontaneous condensation

Daniel Svenšek, Rudolf Podgornik

We investigate condensation of a long confined chiral nematic polymer inside a spherical enclosure, mimicking condensation of DNA inside a viral capsid. The Landau-de Gennes nemati…

Chirality in Block Copolymer Melts: Mesoscopic Helicity from Inter-Segment Twist

Wei Zhao, Thomas P. Russell, Gregory M. Grason

We study the effects of chirality at the segment scale on the thermodynamics of block copolymer melts using self consistent field theory. In linear diblock melts where segments of…

Polymers pushing Polymers: Polymer Mixtures in Thermodynamic Equilibrium with a Pore

Rudolf Podgornik, Jaime Hopkins, V. Adrian Parsegian +1

We investigate polymer partitioning from polymer mixtures into nanometer size cavities by formulating an equation of state for a binary polymer mixture assuming that only one (smal…

Attraction between Neutral Dielectrics Mediated by Multivalent Ions in an Asymmetric Ionic Fluid

Matej Kanduc, Ali Naji, Jan Forsman +1

We study the interaction between two neutral plane-parallel dielectric bodies in the presence of a highly asymmetric ionic fluid, containing multivalent as well as monovalent (salt…

Electromagnetic fluctuation-induced interactions in randomly charged slabs

Vahid Rezvani, Jalal Sarabadani, Ali Naji +1

Randomly charged net-neutral dielectric slabs are shown to interact across a featureless dielectric continuum with long-range electrostatic forces that scale with the statistical v…

Geometric Mechanics of Curved Crease Origami

Marcelo A. Dias, Levi H. Dudte, L. Mahadevan +1

Folding a sheet of paper along a curve can lead to structures seen in decorative art and utilitarian packing boxes. Here we present a theory for the simplest such structure: an ann…

Conformational Collapse of Surface-Bound Helical Filaments

David A. Quint, Ajay Gopinathan, Gregory M. Grason

Chiral polymers are ubiquitous in nature and in the cellular context they are often found in association with membranes. Here we show that surface bound polymers with an intrinsic…

3-dimensional structure of a sheet crumpled into a ball

Anne Dominique Cambou, Narayanan Menon

When a thin sheet is crushed into a small three-dimensional volume, it invariably forms a structure with a low volume fraction but high resistance to further compression. Being a f…

Slack Dynamics on an Unfurling String

J. A. Hanna, C. D. Santangelo

An arch will grow on a rapidly deployed thin string in contact with a rigid plane. We present a qualitative model for the growing structure involving the amplification, rectificati…
