Molecular Plumbing to Bend Self‐Assembling Peptide Nanotubes

Plumbing carbon nanotubes.

Since their discovery, the possibility of connecting carbon nanotubes together like water pipes has been an intriguing prospect for these hollow nanostructures. The serial joining of carbon nanotubes in a controlled manner offers a promising approach for the bottom-up engineering of nanotube structures--from simply increasing their aspect ratio to making integrated carbon nanotube devices. To d...

Molecular dynamical approach to the conformational transition in peptide nanorings and nanotubes.

We study the conformational transition in d,l-peptide nanorings (PNRs) and nanotubes (PNTs) computationally based on the total energy calculation. Ab initio energy calculation has been carried out to investigate the static states of PNRs, whereas the molecular dynamics (MD) calculation has been employed to examine PNRs' dynamical states. We, then, discuss the time-dependent (TD) feature via the...

Role of peptide--peptide interactions in stabilizing peptide-wrapped single-walled carbon nanotubes: a molecular dynamics study.

Single-walled carbon nanotubes (SWNTs) have unique properties and are projected to have a major impact in nanoscale electronics, materials science, and nanomedicine. Yet, these potential applications are hindered by the need for sample purification to separate SWNTs from each other and from metallic catalyst and amorphous carbon present in as-synthesized samples. Common purification strategies ...

Basket, Flat Plumbing and Flat Plumbing Basket Numbers of Links

We define the basket number, the flat plumbing number and the flat plumbing basket number of a link. Then we provide some upperbounds for these plumbing numbers by using Seifert’s algorithm. We study the relation between these plumbing numbers and the genera of links.
