The unique mechanical and electronic properties of multiwall nanotubes are proving to be a rich source of new physics and could also lead to new applications in materials and devices
Scanning tunnelling microscopes (STMs) rely on an ultrafine ‘tip’ to push atoms over a surface. The atoms are pushed either by the tip itself, or by an electric field. The new technique re...
The quantum of conductance, G0, is defined by a simple equation: G0=2e2/h, where e is the charge on the electron and h is the Planck constant. The conductance of an individual nanotube is predicted to...
The Delft group fabricated the electrodes by making a slit in a silicon nitride film with standard lithography. A series of platinum layers were then sputtered across the slit until the gap was reduce...
The 0.5 nm nanotube was made by boring a hole into a graphite rod. The hole was then filled with cobalt metal powder – which acts as a catalyst – and a mixture of nanotubes and other carbo...

Advances in nanotechnology, information science and molecular biology continue at a rapid rate and are poised to spark a series of industrial revolutions in the next millennium
Carbon nanotubes are rolled up sheets of graphite that can have lengths of about 30-100 nanometers and diameters of about a nanometer. Two years ago it was discovered that carbon nanofibres – wh...
As the highly energetic particles pass through conventional carbon-rich rocks, they would form carbon-60 molecules in their wake. The fact that these geological detectors have been “collecting d...
The Vienna team sent a collimated beam of carbon-60 molecules through a slit made of silicon nitride and detected the interference pattern by ionizing the molecules with a laser and then counting the ...
