A new approach to non-covalent peptide-based nanotubular or rod-like structures is presented, whereby the monomeric units are preorganised into a β-strand geometry that templates the formation of an extended and unusual parallel β-sheet rod-like structure. The conformational constraint is introduced by Huisgen cycloaddition to give a triazole-based macrocycle, with the resulting self-assembled ...

We have calculated the electrostatic interaction between two rod-like charged objects with arbitrary orientations in three dimensions. We obtained a closed-form formula expressing the interaction energy in terms of the separation distance between the centers of the two rod-like objects, r, their lengths (denoted by 2l₁ and 2l₂) and their relative orientations (indicated by θ and φ). When the ob...

Novel kinetic models for both Dumbbell-like and rigid-rod like polymers are derived, based on the probability distribution function f(t, x, n, ṅ) for a polymer molecule positioned at x to be oriented along direction n while embedded in a ṅ environment created by inertial effects. It is shown that the probability distribution function of the extended model, when converging, will lead to well acc...

Granular gases are interesting multiparticle systems which, irrespective of the apparent simplicity particle interactions, exhibit a rich scenario so far only little understood features. We have numerically investigated dense granular gas composed frictional spherocylinders which excited mechanically by lateral vibrating container walls. This study was stimulated experiments in microgravity on ...

Background. The double haul is a unique feature of single-handed fly casting and is used in both fly fishing and fly casting competition. The movement behaviour during the double haul has not been investigated in previous research. Objectives. Describe the coordination of the rod and line hauling movements during distance fly casting. Methods. Elite fly casters performed distance castin...

Abstract One of the most intriguing properties rod-like polymers is ability to form a nematic phase. Among broad variety external stimuli promote isotropic (I)-nematic (N) transition, shear-induced phase represents one fascinating phenomena in polymer physics. Here, after reviewing some relevant findings on quiescent and nematics, we present novel isotropic-nematic transition exhibited by poly(...
