Knots in soft condensed matter [PDF]

Journal of Physics: Condensed Matter, 2015
Understanding the mechanism by which a polypeptide chain thread itself spontaneously to attain a knotted conformation has been a major challenge in the field of protein folding. HP0242 is a homodimeric protein from Helicobacter pylori with intertwined helices to form a unique pseudo-knotted folding topology.

Positron Kinetics in Soft Condensed Matter [PDF]

Physical Review Letters, 2009
We outline a new kinetic theory for positrons in soft matter, which blends together cross sections for positrons scattering from single molecules, with the structure function of the medium as a whole. Numerical results are presented for positrons in liquid argon, where negative differential conductivity arises from both positron formation and the ...

Determination of the positions and orientations of concentrated rod-like colloids from 3D microscopy data [PDF]

, 2015
Confocal microscopy in combination with real-space particle tracking has proven to be a powerful tool in scientific fields such as soft matter physics, materials science and cell biology.

Viruses and the physics of soft condensed matter [PDF]

Proceedings of the National Academy of Sciences, 2004
Almost 50 years ago, Francis Crick and James Watson observed that “almost all small viruses are either spheres or rods” and put forth the hypothesis that such viruses were symmetrical arrays of subunits (1). In the following paper in that issue of Nature , Donald Caspar demonstrated that tomato bushy stunt virus had at least cubic symmetry and provided

Small asymmetric Brownian objects self-align in nanofluidic channels [PDF]

, 2019
Although the self-alignment of asymmetric macro-sized objects of a few tens of microns in size have been studied extensively in experiments and theory, access to much smaller length scales is still hindered by technical challenges.

A novel chiral phase of achiral hard triangles and an entropy-driven demixing of enantiomers [PDF]

, 2015
We investigate the phase behavior of a system of hard equilateral and right-angled triangles in two dimensions using Monte Carlo simulations. Hard equilateral triangles undergo a continuous isotropic–triatic liquid crystal phase transition at packing ...

Shock (Blast) Mitigation by “Soft” Condensed Matter [PDF]

MRS Proceedings, 2002
ABSTRACTIt is a common point that “soft” condensed matter (like granular materials or foams) can reduce damage caused by impact or explosion. It is attributed to their ability to absorb significant energy. This is certainly the case for quasistatic type of deformation at low velocity of impact widely used for packing of fragile devices.

Entropy-Driven Phase Transitions in Colloids: From spheres to anisotropic particles [PDF]

, 2015
Colloidal particles with anisotropic interactions can be synthesized by controlling the shape of the particles. Exploiting the self-assembly of these novel colloidal building blocks calls for theoretical tools to predict the structure and phase behavior ...

Quasicrystals from nanocrystals

, 2009
Quasicrystals have a host of unusual physical properties. These intermediates between amorphous solids and regular crystalline materials can now be made to self-assemble from ...

Directed Self-Assembly of Micron-Sized Gold Nanoplatelets into Oriented Flexible Stacks with Tunable Interplate Distance [PDF]

, 2015
A growing demand for control over the interparticle spacing and the orientation of anisotropic metallic particles into self-assembled structures is fuelled by their use in potential applications such as in plasmonics, catalysis, sensing, and ...
