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 ...
Only two other methods have previously been used to manufacture quantum dots: electron beam lithography and epitaxy. Lithography is a top down approach in which the beam defines the dot pattern, where...
The medium is made of nanocrystals of zinc sulphide doped with samarium. Although the nanocrystals are only 3 nanometres long, they clump together into larger particles to form a powder that can be us...
The fantastic progress in the miniaturization of electronic devices that has taken place in the past few decades has largely been made possible by perfecting a century-old technique called lithography...
