The graphite that slips from the point of your pencil onto a page may be of more use than simply writing and drawing. A team of researchers has shown that simple pencil lines can be used as an accurate sensor to measure the deformation of objects.
Since graphite—the dark material used in regular old pencils—and diamonds are both made from carbon, it's technically feasible to turn the former into the latter. You just need to apply a little pressure—about 150,000 times what the atmosphere on Earth's surface is like. But researchers at Stanford University claim to…
Apple rumormonger du jour Sonny Dickson has outed the latest in a series of reputed scoops: An iPhone 5S in not white, black, or gold, but graphite. It sounds potentially lovely! It looks... not so much. Which is why it seems particularly unlikely that this is the real deal.
The dual and quad core processors used in modern smartphones make the devices extremely capable, but also run extremely hot. So to wrangle all that excess heat without adding too much bulk, Panasonic has managed to shrink its graphite heat shields to a mere 10μm (microns) thick. (Size comparison: A human red blood…
When carbon fiber was first trotted out in solid rocket motor cases and tanks in the 1960s, it was poised to not only take on fiberglass, but also a whole host of other materials.
Carbon is one of the most versatile materials in the universe, forming everything from the graphite found in the pencils to hard, sparkling diamonds. But three new forms of carbon might make even the most breathtaking diamond look impossibly dull.
Graphene is pretty cool stuff. It's the foundation of a lot of nanomaterials, and when it's only a single atom thick, it can stretch eternally in two dimensions. When it's more than one atom thick it behaves very differently, becoming graphite (which you often find in pencils). We already know a pretty easy way to …
Are the diamond's days as an indestructible substance numbered? Possibly. At about 170,000 atmospheres, scientists managed to use super-hard graphite to crack one in 2003, but the exact reason why was somewhat of a mystery. Now maybe it's not.
Today, two professors won the Nobel prize for physics "for groundbreaking experiments regarding the two-dimensional material graphene." The Nobel is the Olympic gold of science. But what is graphene, and why did it earn these guys over a million bucks?
A big graphite Kindle DX. A super fast 4G WiMax Wi-Fi Hotspot. A bamboo laptop. For all the mobile warriors who demand the biggest, fastest and eco-friendliest, your devices are now available.
This is what may have happened if Jonathan Ive from Summer 2001—who designed the iMac graphite on the right—had a time machine to travel back and design the Mac SE/20 in 1987.
