In the picture above, electricity is applied to the gold electrodes (which are imprinted in the paper). The carbon nanotube pencil is used to fill in the gaps, and effectively acts as a resistor.

A team of MIT chemists has published a paper revealing how it developed a method for drawing gas sensors onto paper using a tailor-made, super-conductive carbon nanontube pencil. Electrically ...

Now, scientists from MIT have brought similar “hands on” technology to the humble pencil – they’ve compressed carbon nanotubes together to form a pencil lead substitute, that has been used ...

Katherine Mirica and colleagues created a novel type of pencil lead, replacing graphite with a highly compressed powder made of commercially available carbon nanotubes. The resulting newfangled ...

Anyone who has ever taken an SAT has had the sacredness of the No. 2 pencil drilled into them. But what makes a No. 2 pencil what it is? What separates it from a No. 1 or No. 4? And what makes a ...

Researchers have designed a new type of pencil lead in which graphite is replaced with a compressed powder of carbon nanotubes. The lead, which can be used with a regular mechanical pencil ...

The "lead" in your pencil is misnamed. The gray stuff is actually composed of graphite, which is the stablest form of the element carbon. Its bonded atoms are arranged in planar sheets ...

BoO Barcelona based in Spain has created a new lead holder or propelling pencil constructed from carbon fibre providing a lightweight easy-to-use sketching, note taking and drawing tool that is ...

Researchers from Ecole Polytechnique Federale de Lausanne (EPFL) made an interesting energy discovery recently. They found it’s possible to make a small, eco-friendly device that packs a more ...
