Pencils may hold the key to future electronics


Today’s Video of the Day from the American Chemical Society (ACS) describes how the graphite used in lead pencils could ultimately revolutionize the future of electronics, medicine, and even space travel. 

Graphite is a crystalline form of the element carbon which consists of stacked layers of graphene. It is also one of the best conductors in the world because electrons can zip through graphene sheets faster than any other known material. 

In the future, scientists hope to use graphene for renewable energy in batteries, fuel cells and other energy storage methods.

Graphene could also be useful in various biomedical applications, such as sensors that could be placed under the skin to track heart rate or blood sugar.

“The chemistry world has been excited about the possibility of buckyballs, graphene and carbon nanotubes for decades,” says ACS. “But the science has taken a long time to catch up to the hype. So where are we now, and how far away are we from a carbon-powered jetpack future?”
