TEHRAN (FNA)- Iranian researchers from the University of Mazandaran studied the performance of boron nitride
nanotubes in the presence of vitamins through a computational method.
Carbon
nanotubes and graphene for photonic applications.
This method is ideal for making
nanotube solutions for fibre spinning because it produces fluid dopes that closely resemble those used in industrial spinning of high-performance fibres.
One feeler made contact with the other cell, and a
nanotube was formed, while the rest of the feelers retracted into the cell body.
A key advantage over traditional nanoclays is that halloysite
nanotubes do not need exfoliation, which involves separating thin layers of nanoclay (like peeling an onion) with chemicals and other processing steps.
Thousands of
nanotubes easily could fit inside a typical cell.
Tokyo, Japan, Feb 10, 2006 - (JCN) - The National Institute of Advanced Industrial Science and Technology (AIST) announced on February 8 that its Nanotechnology Research Institute has succeeded in encapsulating and stabilizing beta-carotene in carbon
nanotubes.
All CNT/PU films showed higher tensile modulus, yield stress and fracture stress than neat PU, and these parameters increased as the
nanotube concentration increased.
The contact resistance between
nanotube and metal electrodes must be controlled.
Seiichiro Kiyooka, chief analyst at Fuji Keizai, an industry research firm, concurs that Mitsui's efforts in
nanotube mass-production technology will eventually lower costs.
As in a conventional semiconductor transistor, applying a low voltage to the transistor's gate switches the current passing between opposite ends of the
nanotube (the device's source and drain).
To recharge the battery, you merely add energy, forcing the ions back into the
nanotube.
