Another type of nanotube, a how-to guide to making bamboo-structured carbon nanotubes

23.11.2007
Synthesis of bamboo-structured carbon nanotubes on MgO supported bimetallic Cu-Mo catalysts

Nanotechnology is area if science that has recently captured the attention of people all around the world. At the heart of the nanotechnology revolution are carbon nanotubes, amazing materials with astonishing properties. They have applications in most fields, with new possibilities emerging regularly.

Carbon nanotubes are not as straightforward as many believe them to be. Of course there are the simple single walled carbon nanotubes and the more complex multi walled carbon nanotubes, but there are also carbon nanotubes in a number of other forms. By altering reaction conditions, carbon nanotubes also exist as carbon cages, carbon nanohorns and carbon nanotubes with a structure reminiscent of bamboo.

Research work has just been released that provides a detailed analysis of the procedure for synthesising bamboo structured carbon nanotubes (BCNTs). The work by Zhonglai Li, Hongzhe Zhang, Joe Tobin, Michael A. Morris, Jieshan Qiu, Gary Attard and Justin D. Holmes from University College Cork, Dalian University of Technology and Cardiff University has been published in a special edition of the open access journal, AZoJono*.

This special edition of AZoJono features a number of papers from DESYGN-IT, the project seeking to secure Europe as the international scientific leader in the design, synthesis, growth, characterisation and application of nanotubes, nanowires and nanotube arrays for industrial technology.

The present work looked at bamboo-structured carbon nanotubes with a narrow diameter distribution synthesized on bimetallic copper-molybdenum catalysts. Findings included the catalytic nanoparticles playing a key role in the synthesis of the nanotubes as well as acting as nucleation seeds for growth. Raman and thermal gravimetric analysis results showed that the quality of the BCNTs was dependent on the amount of copper present in the catalyst. These results challenge accepted wisdom that significant yields of CNTs can only be formed from catalytic CVD routes if first row or mid-row transition elements are used as catalysts.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
