Halloysite nanotubes with carboxylic or polycarboxylic functionalities can affect the growth of calcium and magnesium silicate hydrates at nanoscale.

Control over when and where nanostructures arise is essential for the self-assembly of dynamic or multicomponent devices. We design and construct a DNA origami seed for the control of DAE-E tile DNA nanotube assembly. Seeds greatly accelerate nanotube nucleation and growth because they serve as nanotube nucleation templates. Seeds also control nanotube circumference. Simulations predict nanotub...

A multi-scale method to predict the stiffness and stability properties of carbon nanotube-reinforced laminates has been developed. This method is used in the prediction of the buckling behavior of laminated carbon nanotube-polyethylene composites formed by stacking layers of carbon nanotube-reinforced polymer with the nanotube alignment axes of each layer oriented in different directions. Linki...

Electron field emission measurements have been made on multiwall arc discharge carbon nanotubes embedded in a conjugated polymer host. Electron emission at low nanotube content is observed and attributed to an enhancement of the applied electric field at the polymer/nanotube/vacuum interface where the electron supply through the film is attributed to fluctuation induced tunneling in a disordere...

Substrate and nanotube polarization are shown to qualitatively change a nanotube bandstructure. The effect is studied in a linear approximation in an external potential which causes the changes. A work function difference between the nanotube and gold surface is estimated to be large enough to break the band symmetry and lift a degeneracy of a lowest but one subband of a metallic nanotube. This...
